En primer lugar, el artículo explora lo que los biógrafos de Humboldt han llamado “ein zweiter Kolumbus” (un segundo Colón). En segundo lugar, se traza la historia de la edificación humboldtianna de una “imaginación poética” y de una “geografía mítica” atribuidas por Humboldt a Cristóbal Colón.

En premier lieu, il explore ce que les biographes de Humboldt ont appelé “ein zweiter Kolumbus” (un deuxième Colomb). En deuxième lieu, il trace l’histoire d’une « imagination poétique » et d’une « géographie mythique », attribuées par Humboldt à Christophe Colomb. N2 - This article explores Alexander von Humboldt’s reception of Christopher Columbus as a historical figure, mainly in his Relation historique and in his Examen critique. First of all, it explores what Humboldt’s biographers have referred to as a “zweiter Kolumbus” (a second Columbus). It then proceeds to trace the history of a “poetic imagination” and a “mythical geography” attributed by Humboldt to Christopher Columbus.

Dieser Artikel untersucht die Fußnoten in Humboldts Essai politique sur l‘île de Cuba (1826). Zwar ist es nicht immer leicht, die manchmal recht geheimnisvollen Verweise zu entschlüsseln, dennoch lohnt sich der Versuch: Humboldts Fußnoten geben nicht nur Auskunft über seine umfassenden Netzwerke des Wissens. Sie verweisen auch auf Auseinandersetzungen verschiedener Gelehrter über Humboldts Schriften. Schließlich beinhalten sie Humboldts Reaktionen auf solche Auseinandersetzungen. Eine Untersuchung von Humboldts Fußnoten erlaubt es folglich dem Leser, mehr über Humboldt den Wissenschaftler aber auch Humboldt den Mensch zu erfahren. N2 - When it comes to footnotes, Alexander von Humboldt was ahead of his times even though his references leave much to be desired by today’s academic standards. This article examines the footnotes of Humboldt’s Essai politique sur l‘île de Cuba (1826). While it is not always easy to decipher his sometimes cryptic references, the undertaking is worthwhile: Humboldt’s footnotes do not only reveal his vast networks of knowledge. They also provide glimpses of ongoing, contemporary disputes among different scholars that involve Humboldt’s writings. They also present Humboldt’s reactions to such disputes. Exploring Humboldt’s footnotes consequently allows the reader to access both Humboldt the scholar and Humboldt the human being. N2 - Quand il s’agit de notes, Alexandre de Humboldt était en avance sur son temps, même si ses références laissent beaucoup à désirer par rapport aux normes universitaires d’aujourd’hui. Cet article examine les notes de l’Essai Politique sur l‘île de Cuba de Humboldt (1826). Même s’il n’est pas toujours facile de déchiffrer ses références parfois cryptiques, l’entreprise vaut la peine: les notes de Humboldt ne révèlent pas seulement ses vastes réseaux de savoir. Ils fournissent également des aperçus de conflits contemporains en cours entre les différents spécialistes qui s’occupent des écrits de Humboldt. Ils présentent également les réactions de Humboldt à de tels différends. Explorer les notes de Humboldt permet donc au lecteur d’accéder à la fois Humboldt le savant et Humboldt l’être humain.

Deshalb wird auch dieser Brief zum ersten Mal vollständig veröffentlicht. N2 - Le court article donne une vue d’ensemble de la correspondance conservée entre A. v. Humboldt et Charles Lyell. En plus, il publie une lettre sans date et inconnue jusqu’aujourd’hui de Humboldt à Lyell qui peut être datée au moyen d’une lettre à Pertz. Pour cette raison, cette lettre est aussi publiée complètement pour la première fois. N2 - The short paper gives a survey of the preserved correspondence between A. v. Humboldt and Charles Lyell. Moreover it publishes an undated, hitherto unknown letter of Humboldt to Lyell that can be dated by means of a letter to Pertz. For that reason this letter is also completely published for the first time.

Más aun, de ahí en adelante este marco además le serviría para darle sentido de conjunto a las incontables y diversas informaciones que recogería en los restantes cinco años de viaje. Para poner en evidencia el enfoque de la visita a Tenerife de Humboldt, analizo su relato de la ascensión al Teide suponiendo que está estructurado según los relatos de viajes épicos y peregrinaciones. N2 - In dieser kurzen Abhandlung wird dargelegt, dass Alexander von Humboldt durch die Besteigung des Teide eine integrierende Perspektive erwerben konnte, die ihm als Rahmen wissenschaftlicher Kommunikation dienen würde um die Vielzahl der Daten, welche er sich vorgenommen hatte auf der Insel zu sammeln, zu vereinen. Darüber hinaus wird ihm dieser Rahmen von hier an auch dazu dienen, um den unzähligen und verschiedenartigen Informationen, die er in den verbleibenden fünf Reisejahren sammeln würde, einen einheitlichen Sinn zu geben. Um die Blickrichtung von Humboldts Besuch auf Teneriffa darzulegen, untersuche ich seinen Bericht über die Besteigung des Teide unter der Annahme, dass er den Aufbau epischer Reisen und Pilgerfahrten hat. N2 - In this brief essay I propose that, with the ascent of the Teide, Alexander von Humboldt was able to acquire an integrating perspective that served him as a framework for scientific communication to unify the multitude of data that he had set out to collect during his brief stay on the island. Moreover, thereafter this framework would also serve him to give a unified sense to the countless and diverse kinds of information that he could collect during the remaining five years of travel. To bring out the focus of Humboldt’s visit to Tenerife, I analyse his account of the ascent of the Teide by assuming that it is structured in the manner of the stories of epic journeys and pilgrimages.

Learning outcomes and competencies are designed to sensitize students to the many cultural backgrounds of U.S. learning institutions. Nevertheless, true globality, as represented through diverse discourses and perspectives of the world, still seems neglected in curricula and course assignments. This article explores the possibilities offered through a new shared space in education where different forms of networked knowledge and multifaceted perspectives can build a global platform of exchange in a diverse student population. The universal science concept described by Alexander von Humboldt at the beginning of the 19th Century illuminates this intertwined approach to knowledge of the world, which has the potential to positively impact contemporary curricula and course design. Von Humboldt’s writings emphasize inclusion and interplay among cultures and natural phenomena. By inviting our students to be active representatives of diverse discourses, these interconnecting links will become more transparent. In turn, productive forms of knowing about the world may enrich current learning objectives and thereby reflect a true global citizenship as it evolves in a new shared space of education. Keywords: global citizenship, plurality, diverse discourses, multicultural education. N2 - Weltbürgerschaft und kulturelle Vielfalt sind überall gegenwärtige Konzepte im heutigen Bildungswesen. In den Vereinigten Staaten werden Lernziele und Kompetenzen geformt, um die Studenten gegenüber den vielen kulturellen Hintergründen, die in den Bildungsinstitutionen vorzutreffen sind, zu sensibilisieren.Trotzdem wird wahre Globalität, wie sie heute in den vielfältigen Diskursen und Perspektiven der Welt repräsentiert ist, immer noch in Lehrplänen und Studienarbeiten vernachlässigt. Dieser Artikel untersucht die Möglichkeiten, die sich heute im Bildungswesen durch den neuen, gemeinsam geteilten, globalen Bildungsraum anbieten, in dem die multikulturelle Studentenbevölkerung verschiedene Formen vernetzten Wissens und facettenreiche Perspektiven der Welt eine globale Plattform des Austausches bildet. Das von Alexander von Humboldt am Anfang des neunzehnten Jahrhunderts beschriebene universale Wissenschaftskonzept, beleuchtet solch einen vernetzten Ansatz an ein Wissen um die Welt, der auf heutige Bildungskonzepte und Kursdesigns einen positiven Einfluss nehmen könnte. Humboldts Schriften unterstreichen die Bedeutung der Inklusivität und des Wechselspiels zwischen Kulturen und Naturphänomenen. Indem wir Studenten mit unterschiedlichem kulturellen Hintergrundwissen dazu einladen, ihre jeweiligen Diskurse des Wissens aktiv zu repräsentieren, werden diese gegenseitig mit einander verknüpten Beziehungen des Wissens transparenter. Auf diese Weise, entsteht die Möglichkeit, heutige Lernziele mit neuen, produktiven Formen des Weltwissens zu berreichern, worin sich ein wahres Weltbürgertum, wie es sich in diesem neuen Bildungsraum des globalen Austausches hervortut, wiederspiegeln würde. N2 - La citoyenneté mondiale et la diversité figurent aujourd’hui parmi les concepts les plus représentés dans les études supérieures. Les résultats de l’apprentissage et les compétences sont conçus pour rendre les étudiants sensibles aux nombreuses origines culturelles des établissements d’instruction des États-Unis. Néanmoins, la vraie globalité, représentée à travers des perspectives et des discours divers, semble être toujours négligée dans les programmes scolaires et les attributions de cours. Dans cet article l’auteur explore les possibilités offertes par un nouvel espace partagé dans le domaine de l’éducation -- une éducation caractérisée d’ailleurs par des formes variées de connaissances atteintes dans des réseaux différents et en des perspectives multiples qui peuvent contribuer à construire une plate-forme globale d’échange dans une population d’étudiants hétérogène. Le concept de la science universelle décrit par Alexander von Humboldt au début du dix-neuvième siècle éclaire cette approche étroitement liée aux connaissances du monde qui a le potentiel d’avoir un impact positif sur les programmes scolaires contemporains et les conceptions des cours. En effet, dans son oeuvre Von Humboldt met l’emphase sur l’importance de l’inclusion et de l’interaction entre les cultures et les phénomènes naturels. En invitant nos étudiants à être des représentants actifs de discours divers, ces liens d’interconnexion leur seront de plus en plus évidents. Par conséquent, il se peut que les objectifs du savoir puissent être enrichis par ces façons différentes de connaître le monde tandis qu’ils réflèteront de plus en plus une véritable citoyenneté mondiale qui évoluera en même temps en réponse à ce nouvel espace partagé dans l’éducation contemporaine. Mots-clés: la citoyenneté mondiale, la pluralité, les discours divers, l’éducation multiculturelle.

Das 1807 während der Franzosenzeit in Berlin entstandene Porträt verweist als Teil eines im Conseil d’État in Paris aufbewahrten Porträt-Albums auf die Zirkel und Beziehungen, die sich in der besetzten preußischen Hauptstadt zwischen Besatzern, jüdischen Salonkreisen und der wissenschaftlichen Community gebildet haben, ein Nährboden für den transnationalen Austausch von Vertretern einer jungen und vitalen Generation, die sich als echte Europäer verstanden. N2 - Un portrait jusqu’à présent inédit d’Alexander von Humboldt par Frédéric d’Houdetot, élève de Jacques-Louis David, enrichit l’iconographie humboldtienne d’une effigie qui donne à voir le célèbre voyageur et érudit en jeune homme, quelques années seulement après son retour des Amériques – un portrait qui frappe par sa vitalité, sa concentration et la forte présence du savant. Dessiné dans le contexte de l’occupation de Berlin par l’armée napoléonienne et conservé au Conseil d’Etat à Paris, ce portrait est issu d’un album réunissant un grand nombre d’autres portraits de Berlinois des années 1800, qui témoigne des relations étroites que l’occupant put entretenir avec les représentants de l’élite juifs de la ville et la communauté scientifique, dans une dynamique propice aux échanges transnationaux d’une génération jeune, vitale et profondément européenne. N2 - A previously unreleased portrait of Alexander von Humboldt, drawn by Jacques-Louis David’s disciple Frédéric d’Houdetot, adds a lively, focused and astonishingly present image to the iconography of Humboldt, that of the famous traveler and scholar as a young man, a few years after his return from the Americas. The effigy, traced in 1807 Berlin during the French occupation, is part of an album of portraits by Houdetot conserved in the Conseil d’État in Paris and throws some light upon the relationships that formed in the Prussian capital between members of the occupying forces, Jewish salon circles and the scientific community – a breeding ground for the transnational exchange of representatives of a young and vital generation that saw themselves as true Europeans.

Der kodikologische Aspekt beinhaltet eine umfassende Erfassung aller physischen Merkmale und Besonderheiten der Tagebücher, wobei ein Fokus auf die Zusammenstellung der Lagen, auf heraus getrennten oder ganz fehlenden Seiten liegt. Dies geschieht vor dem Hintergrund, die ursprüngliche Zusammenstellung der Tagebücher zu rekonstruieren, die Genese zu erforschen und im Nachlass befindliche Teile ggf. fehlenden Blättern oder Fragmenten in den Tagebüchern zuzuordnen. Wasserzeichenaufnahmen mit der Thermographiekamera und Tintenanlaysen mithilfe der Röntgenfluoreszenztechnik können dabei helfen aufzuzeigen, wie die Tagebücher entstanden sind und wie sie bis zum Tod Alexander von Humboldts von ihm als Arbeitsinstrument genutzt wurden. N2 - El artículo trata de los resultados codicológicos y exámenes tecnológicos sobre los aspectos materiales (papeles, tintas) de los Diarios del viaje americano. El aspecto codicológico incluye una revisión extensa de las características y particularidades materiales de los diarios, enfocando las encuadernaciones y las páginas separadas o faltantes. La revisión tiene como fin de reconstruir la compilación original de los diarios, de explorar su génesis y de adjudicar partes (fragmentos, folios faltantes) del legado a los diarios tal como los tenemos hoy. Las marcas de agua se registran con la cámara termográfica, el análisis de las tintas usadas se realiza con ayuda de un sistema de medida por fluorescencia de rayos X. Esto contribuirá a mostrar como evolucionaron los diarios de viaje y como fueron usadas por Alejandro de Humboldt a lo largo de su vida y hasta antes de su muerte. N2 - The American Travel Diaries’ paper and writing materials have been examined under codicological aspects as well as in terms of material based technologies. The report on the codicology includes a comprehensive survey of all physical features and specifics within the diaries. The examination is focused on the structure of the gatherings and cut-out or missing leafs. This is done in order to reconstruct the original compilation of the diaries, to research on their genesis and to possibly allocate parts of the bequest to missing pages or fragments in the diaries. Images taken of watermarks with the help of a thermographical camera and the analysis of the inks with the X-ray fluorescence method can help to show how the Travel Diaries were created in the first place and how they have been used by Alexander von Humboldt as a continuous working-tool until his death.

Der vorliegende Aufsatz will ausgehend vom Scheitern einer eindeutigen gattungsgeschichtlichen Zuschreibung die Sonderstellung der Bände als Instrumente der Erfahrung herausarbeiten, welche an der Schwelle zum 19. Jh. den ontologischen Optimismus sowie das methodische Tasten eines Wissenschaftlers, Schriftstellers und Forschungsreisenden in subjektbezogener Form zugänglich machen. Gerade der multifunktionale Charakter der ‚Journale‘ als Log- bzw. Reisetagebücher und Skizzenhefte, die noch weit entfernt von der Ordnung wissenschaftlichen Schreibens scheinen, lassen jene Voraussetzungen wissenschaftlicher Erkenntnisprozesse sichtbar werden, mithilfe derer Humboldt innerhalb der kantschen Koordinaten Raum und Zeit einen ‚Rhythmus‘ situativ verarbeiteter Natur- und Welterfahrung in ein dynamisches Speichermedium einfließen lässt. N2 - Les Journaux de Voyage Américains lancent un défi aux études de l’épistémologie historique. Basé sur l’échec d’une attribution explicite à un genre littéraire bien défini, cet essai veut souligner la position exceptionnelle des volumes comme instruments d’expérience, lesquels, à l’aube du 19ème siècle, donnent accès à l’optimisme ontologique, ainsi qu’à l’échantillonnage méthodologique d’un écrivain, scientifique et explorateur, qui devient manifeste comme sujet découvrant. D’une part, le caractère multifonctionnel des cahiers comme journaux de bord, journaux de voyage et carnets de croquis semble un éloignement de l’ordre formel d’une écriture scientifique, d’autre part, ce caractère dévoile les conditions préalables pour les processus épistémologiques qui conduisent à connaissances scientifiques. Dans les coordonnés kantiennes de l’espace et du temps, Humboldt semble suivre son propre rythme épistémologique d’expérience de la situation, qui concerne la nature et le monde à coup d’un moyen de stockage dynamique. N2 - The American Travel Diaries represent a challenge for the studies of historical epistemology. Based on the failure of their explicit attribution to a well-defined literary genre, this paper wants to emphasize the exceptional position of the volumes as instruments of experience, which, at the dawn of the 19th century, grant access to the ontological optimism, as well as to the methodological sampling of a scientist, writer and explorer, who becomes manifest as experiencing subject. On the one hand, the multi-functional character of the Diaries as log-, travel- and sketchbooks seems to distance them from the formal order of scientific writing, on the other hand, they unveil the prerequisites for epistemological processes that lead to scientific knowledge. Within the Kantian coordinates of space and time, Humboldt seems to follow his own epistemological rhythm of situational experience concerning nature and world by means of a dynamic storage medium.

These focus points center around three pillars: relationality, the reciprocity of science and aesthetics and movement.

A1 - Malatesta, Davide A1 - Granacher, Urs T1 - Effects of three types of exercise interventions on healthy old adults’ gait speed BT - a systematic review and meta-analysis JF - Sports medicine N2 - Background: Habitual walking speed predicts many clinical conditions later in life, but it declines with age. However, which particular exercise intervention can minimize the age-related gait speed loss is unclear. Purpose: Our objective was to determine the effects of strength, power, coordination, and multimodal exercise training on healthy old adults' habitual and fast gait speed. Methods: We performed a computerized systematic literature search in PubMed and Web of Knowledge from January 1984 up to December 2014. Search terms included 'Resistance training', 'power training', 'coordination training', 'multimodal training', and 'gait speed (outcome term). Inclusion criteria were articles available in full text, publication period over past 30 years, human species, journal articles, clinical trials, randomized controlled trials, English as publication language, and subject age C65 years. The methodological quality of all eligible intervention studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. We computed weighted average standardized mean differences of the intervention-induced adaptations in gait speed using a random-effects model and tested for overall and individual intervention effects relative to no-exercise controls. Results: A total of 42 studies (mean PEDro score of 5.0 +/- 1.2) were included in the analyses (2495 healthy old adults; age 74.2 years [64.4-82.7]; body mass 69.9 +/- 4.9 kg, height 1.64 +/- 0.05 m, body mass index 26.4 +/- 1.9 kg/m(2), and gait speed 1.22 +/- 0.18 m/s). The search identified only one power training study, therefore the subsequent analyses focused only on the effects of resistance, coordination, and multimodal training on gait speed. The three types of intervention improved gait speed in the three experimental groups combined (n = 1297) by 0.10 m/s (+/- 0.12) or 8.4 % (+/- 9.7), with a large effect size (ES) of 0.84. Resistance (24 studies; n = 613; 0.11 m/s; 9.3 %; ES: 0.84), coordination (eight studies, n = 198; 0.09 m/s; 7.6 %; ES: 0.76), and multimodal training (19 studies; n = 486; 0.09 m/s; 8.4 %, ES: 0.86) increased gait speed statistically and similarly. Conclusions: Commonly used exercise interventions can functionally and clinically increase habitual and fast gait speed and help slow the loss of gait speed or delay its onset.

T1 - Endogenous murine leukemia retroviral variation across wild European and inbred strains of house mouse JF - BMC genomics N2 - Background: Endogenous murine leukemia retroviruses (MLVs) are high copy number proviral elements difficult to comprehensively characterize using standard low throughput sequencing approaches. However, high throughput approaches generate data that is challenging to process, interpret and present. Results: Next generation sequencing (NGS) data was generated for MLVs from two wild caught Mus musculus domesticus (from mainland France and Corsica) and for inbred laboratory mouse strains C3H, LP/J and SJL. Sequence reads were grouped using a novel sequence clustering approach as applied to retroviral sequences. A Markov cluster algorithm was employed, and the sequence reads were queried for matches to specific xenotropic (Xmv), polytropic (Pmv) and modified polytropic (Mpmv) viral reference sequences. Conclusions: Various MLV subtypes were more widespread than expected among the mice, which may be due to the higher coverage of NGS, or to the presence of similar sequence across many different proviral loci. The results did not correlate with variation in the major MLV receptor Xpr1, which can restrict exogenous MLVs, suggesting that endogenous MLV distribution may reflect gene flow more than past resistance to infection.

But only one letter has survived. This letter was written by Kreil on September 3, 1836; one day later Kreil wrote a letter to Carl Friedrich Gauss with nearly the same contents, some sentences are even literally corresponding. Four letters from Kreil to Humboldt were published in the „Annalen der Physik und Chemie“. Some letters were mentioned in the biographical literature dealing with Kreil. These letters show, that the correspondence covered at least the period until 1851 and give information about the intensive relationship between the two scientists. A further interesting source is the library of Humboldt which unfortunately has not survived. The catalogue mentions nine works of Kreil some of them where annotated by Humboldt. This makes it plausible that the contacts even lasted until 1856. N2 - Die Korrespondenz zwischen Alexander von Humboldt und Karl Kreil war umfangreich und betraf den Erdmagnetismus. Aber heute ist nur noch ein einziger Brief im Original bekannt. Dieser Brief, den Kreil am 3. September 1836 Alexander von Humboldt zukommen ließ, stimmt inhaltlich und teilweise wortwörtlich mit dem Brief überein, den Kreil nur einen Tag später, am 4. September 1836, an Carl Friedrich Gauß schickte. Vier Briefe von Kreil an Humboldt wurden in den „Annalen der Physik und Chemie“ publiziert, eine nicht allzu große Anzahl weiterer Briefe an Humboldt wurde in der biographischen Literatur über Kreil und in Briefen Kreils an Koller und Gauß erwähnt. Aber nicht nur die lückenhafte und bruchstückhaft bekannte Korrespondenz zwischen Humboldt und Kreil, die bis 1851 reicht, gibt Aufschluss über die Beziehungen, sondern von besonderer Bedeutung ist des Weiteren der Bestand an Kreiliana in der Bibliothek Humboldts. Es handelt sich um neun Werke Kreils, das letzte aus dem Jahr 1856. Nachweisbare Kontakte zwischen Kreil und Humboldt fanden also mit Sicherheit mindestens bis zu diesem Jahr statt! N2 - La correspondance entre Alexander von Humboldt et Karl Kreil était volumineuse et concernait le magnétisme terrestre. Mais aujourd’hui, une seule lettre originale est encore connue. Kreil a envoyé cette lettre à Humboldt le 3 septembre 1836. C’est partiellement la même lettre – même les phrases coincident parfois – que Kreil a écrite à Carl Friedrich Gauss un jour plus tard. Quatre lettres de Kreil à Humboldt ont été publiées dans les „Annalen der Physik und Chemie“. Quelques lettres sont mentionnées dans la litérature biographique concernant Kreil. Les lettres démontrent que la correspondance peut être attribuée au moins à la période jusque 1851 et révèlent la relation intensive entre les deux savants. La bibliothèque de Humboldt qui malheureusement n’existe plus est une autre source intéressante. Le catalogue mentionne neuf oeuvres de Kreil dont quelques sont annotées par Humboldt. Donc, les contacts existaient vraisemblablement au moins jusque 1856.

Dabei zeigte er nicht nur, dass er als Experimentator und Teil der wissenschaftlichen Gemeinschaft fähig war, sich mit einem so neuen und komplexen Phänomen zu beschäftigen. Es lässt sich auch erkennen, dass er bereits in dieser frühen Schrift versuchte, das umfangreiche Wissen dem Leser zugänglich zu machen. Der Artikel betrachtet Humboldts Galvanismusschrift Versuche über die gereizte Muskel- und Nervenfaser (1797–1798) und untersucht einige Elemente wie Anhänge und Schreibstil, die Humboldt nutzte, um die umfangreichen Informationen zu ordnen und dem Leser so neben den Big Data seiner Erkenntnisse auch passende Suchfunktionen zur Verfügung zu stellen, die eine gezielte Nutzung überhaupt ermöglichen. N2 - In the early stages of his scientific career, Alexander von Humboldt took an interest in experiments in galvanism. He publicised the results in a two-volume work under the title Versuche über die gereizte Muskel- und Nervenfaser (Experiments on the Stimulated Muscle and Nerve Fibre) in 1797 and 1798. In this treatise, he presented himself as competent experimenter and member of the scientific community, but also demonstrated that he was capable of researching new and complex phenomena. These volumes also provide insight into his early attempts to facilitate the readers’ access to the extensive information he had compiled. This article analyses some aspects of Humboldt’s efforts to arrange his vast numbers of observations and theories, for example by means of appendices and narrative style, which he used not only to present the resulting big data collected during his research, but also to make it possible for the reader to organise and utilise this data. N2 - A temprana edad Alexander von Humboldt se dedicó a galvanismo. En 1797 y 1798 publicó los resultados en dos amplios volúmenes llamados Experiencias acerca del galvanismo, y en general sobre la irritacion de las fibras musculares i nerviosas (Versuche über die gereizte Muskel- und Nervenfaser). Así se presentó como experimentador inteligente y se estableció en la comunidad científica porque no sólo demostró ser capaz de dedicarse a un fenómeno tan nuevo y complejo sino también es evidente que en este tratado temprano tuvo la intención de poner al alcance de los lectores todas las informaciones coleccionadas. Este artículo analiza algunos aspectos como los apéndices y la forma de escribir que Humboldt empleó para ordenar sus numerosas observaciones y teorías. Aparte de eso, usó estos elementos para que el lector pueda organizar y utilizar sus datos por sí solo.

Während seine Studien der Pflanzen- und Tierwelt bis heute große Aufmerksamkeit genießen, wird Humboldts Beitrag zu der Entwicklung der modernen Landwirtschaft wenig beachtet. Während seines Aufenthalts in Lima erhielt er Proben von Guano, Vogelmist von den Chincha-Inseln vor der peruanischen Küste. Einige Proben, die er von dieser Reise zurückbrachte, wurden von Wissenschaftlern in Frankreich und Deutschland untersucht. Die Analysenergebnisse zeigten außerordentlich hohe Gehalte an Pflanzennährstoffen, insbesondere Stickstoff und Phosphor. In den folgenden Jahrzehnten wurde Guano zu einem bedeutsamen Düngemittel und Auslöser eines Booms in Europa und Peru. Die Auswirkungen dieser Entwicklung sind bis heute sichtbar und werden hier unter besonderer Beachtung von Phosphor beschrieben. N2 - One aspect of Humboldt’s travel to South America (1799─1804) received little attention. The fascination of his studies of the South American flora and fauna is unbroken to the present day. Yet Humboldt’s contribution to modern agriculture remains almost unnoticed. During his stay in Lima Humboldt received samples of guano, a mixture of bird droppings from the Chincha Islands off the Peruvian coast, which he took to Europe and had analyzed by the most famous chemists in France and Germany. The results showed outstanding fertilizing effects, in particular due to the high content of nitrogen and phosphorus. The ensuing boom starting from the 1840s influenced agriculture in Europe and the economy of Peru seriously. Some aspects of this historical development may give an idea of the ensuing change not only in agriculture. N2 - Il y a un aspect du voyage de Alexander von Humboldt en Amérique du Sud (1799─1804) qui jusqu’à présent a été peu considéré. Ses études de la flore at le da faune de l’Amérique du Sud ont attiré une large attention du public. Or, son influence au développement de l´agriculture moderne est plutôt ignoré. Pendant son séjour à Lima, Humboldt reçut des échantillons de guano qui est composé des excréments d’oiseaux des Iles Chincha face à la côte du Pérou. Humboldt les faisait examiner par des scientifiques français et allemands. Les résultats des analyses montraient des teneurs extraordinaires de nutriments pour plantes, en particulier d´azote et de phosphore. Pendant les décennies suivantes le guano devenait une source indispensable comme fertilisant et a créé un boom en Europe et au Pérou.

Los filósofos franceses Bruno Latour y Philippe Descola supieron destacar, aunque por caminos diferentes, la importancia de este nexo para asegurar la supervivencia del hombre; Bruno Latour centra sus reflexiones en la política de la naturaleza y Philippe Descola destaca el carácter ecológico de la naturaleza y la cultura. Sin embargo, ambos dejan de lado las literaturas del mundo y su capacidad de atesorar los diversos diseños del saber convivir entre hombre y naturaleza y las nociones de sustentabilidad. Descuella además la inspiración que Descola encuentra en la figura del gran erudito Alexander von Humboldt, quien en el siglo XIX ya daba fe de la relación inextricable entre naturaleza y cultura en innumerables testimonios, entre otros, el Chimborazo que, como cuadro global es representativo para entender que la naturaleza desde siempre ha sido cultura y la cultura es inimaginble sin la naturaleza. N2 - Im Vordergrund der vorliegenden Arbeit steht die unauflösbare Beziehung von Natur und Kultur, sowie die Nicht-Natürlichkeit derselben, Produkt der jahrhundertealten Eingriffe des Menschen, subsummiert unter dem Begriff des Anthropozän. Die französischen Philosophen Bruno Latour und Philippe Descola hoben, wenn auch auf unterschiedlichen Wegen, die Bedeutung dieses Zusammenhanges für die Gegenwart und Zukunft der Menschheit hervor; Bruno Latour konzentrier sich auf die Politik der Natur, Philippe Descola unterstreicht den ökologischen Charakter von Natur und Kultur. Beide lassen jedoch die Literaturen der Welt und ihre Fähigkeiten, die unterschiedlichen Entwürfe des Zusammenlebens und die Grundlagen der Nachhaltigkeit zu speichern, außen vor. Es wird auch auf Descolas Inspiration in der Figur des herausragenden Gelehrten Alexander von Humboldt eingegangen, der schon im 19. Jahrhundert in unzähligen Zeugnissen, unter anderem, das über den Chimborazo, das stellvertretend für ein Weltgemälde ist, auf die Unzertrennlichkeit von Natur und Kultur hingewiesen hatte. N2 - This paper investigates the inextricable correlation between nature and culture and the 'no naturality' of the first, product of men's millenarian interventions, subsumed in the word "anthropocene". French philosophers Bruno Latour and Philippe Descola emphasized, in different ways, the importance of this relation for humans present and future. Bruno Latour works out the politics of nature, Philippe Descola underscore the ecological character of nature and culture. Both disregard the literatures of the world and their capabilities to store different drafts of conviviality and the fundaments of sustainability. Descolas inspiration in the outstanding figure of the 19th century, Alexander von Humboldt is also mentioned, and the inseparableness of nature and culture which the erudite distinguished in innumerable testimonies, for example, the one about the Chimborazo.

This approach is applicable for a wide range of X-ray photon energies as well as for a broad range of excitation wavelengths and requires no external fields or changes of temperature. Moreover, the cross-correlator can be employed on a 10 ps or 100 fs time scale featuring up to 50% total X-ray reflectivity and transient signal changes of more than 20%. (C) 2016 Author(s).

Polycomb complexes are central to this memory, but many aspects of the underlying mechanism remain unclear. LIKE HETEROCHROMATIN PROTEIN 1 (LHP1) binds Polycomb-deposited H3K27me3 and is required for repression of many Polycomb target genes in Arabidopsis. Here we show that LHP1 binds RNA in vitro through the intrinsically disordered hinge region. By independently perturbing the RNA-binding hinge region and H3K27me3 (trimethylation of histone H3 at Lys27) recognition, we found that both facilitate LHP1 localization and H3K27me3 maintenance. Disruption of the RNAbinding hinge region also prevented formation of subnuclear foci, structures potentially important for epigenetic repression.

This is mainly caused by the polygenetic nature of shallow‐water carbonate substrates, local carbon cycle processes causing considerable neritic–pelagic isotope gradients and the presence of hiatal surfaces resulting in extremely low carbonate preservation rates. Provided here is an in‐depth petrographic and geochemical evaluation of different carbonate phases of a mid‐Cretaceous (Barremian–Aptian) shallow‐water limestone succession (Jabal Madar section) deposited on the tropical Arabian carbonate platform in Oman. The superposition of stable isotope signatures of identified carbonate phases causes a complex and often noisy bulk carbon isotope pattern. Blocky sparite cements filling intergranular pores and bioclastic voids evidence intermediate to (arguably) deep burial diagenetic conditions during their formation, owing to different timing or differential faulting promoting the circulation of fluids from variable sources. In contrast, sparite cements filling sub‐vertical veins reveal a rock‐buffered diagenetic fluid composition with an intriguing moderate enrichment in 13C, probably due to fractionation during pressure release in the context of the Miocene exhumation of the carbonate platform under study. The presence of abundant, replacive dedolomite in mud‐supported limestone samples forced negative carbon and oxygen isotope changes that are either associated with the thermal breakdown of organic matter in the deep burial realm or the expulsion of buried meteoric water in the intermediate burial realm. Notwithstanding the documented stratigraphically variable and often facies‐related impact of different diagenetic fluids on the bulk‐rock stable isotope signature, the identification of diagenetic end‐members defined δ13C and δ18O threshold values that allowed the most reliable ‘primary’ bulk carbon isotope signatures to be extracted. Most importantly, this approach exemplifies how to place regional shallow‐water stable isotope patterns with evidence for a complex multi‐stage diagenetic history into a supraregional or even global context.

The dynamic of the surface crust is evaluated by a change-detection approach using the Iterative-reweighted Multivariate Alteration Detection (IR-MAD) based on the Landsat archive imagery from 1984 to 2015. The results show that the salt pan is a highly dynamic and heterogeneous landform. A change gradient is observed from very stable pan border to a highly dynamic central pan. On the basis of hyperspectral EO-1 Hyperion images, the current distribution of surface evaporite minerals is characterized using Spectral Mixture Analysis (SMA). Assessment of field and image endmembers revealed that the pan surface can be categorized into three major crust types based on diagnostic absorption features and mineralogical ground truth data. The mineralogical crust types are related to different zones of surface change as well as pan morphology that influences brine flow during the pan inundation and desiccation cycles. These combined information are used to spatially map depositional environments where the more dynamic halite crust concentrates in lower areas although stable gypsum and calcite/sepiolite crusts appear in higher elevated areas.

T1 - The Role of Sustainable Investment in Climate Policy JF - Sustainability N2 - Reaching the Sustainable Development Goals requires a fundamental socio-economic transformation accompanied by substantial investment in low-carbon infrastructure. Such a sustainability transition represents a non-marginal change, driven by behavioral factors and systemic interactions. However, typical economic models used to assess a sustainability transition focus on marginal changes around a local optimum, whichby constructionlead to negative effects. Thus, these models do not allow evaluating a sustainability transition that might have substantial positive effects. This paper examines which mechanisms need to be included in a standard computable general equilibrium model to overcome these limitations and to give a more comprehensive view of the effects of climate change mitigation. Simulation results show that, given an ambitious greenhouse gas emission constraint and a price of carbon, positive economic effects are possible if (1) technical progress results (partly) endogenously from the model and (2) a policy intervention triggering an increase of investment is introduced. Additionally, if (3) the investment behavior of firms is influenced by their sales expectations, the effects are amplified. The results provide suggestions for policy-makers, because the outcome indicates that investment-oriented climate policies can lead to more desirable outcomes in economic, social and environmental terms.

First, crop rotations are identified as a suitable tool for the assessment of the long-term effects of perennial polycultures on ecosystem services, which are not visible at the single-crop level. Second, the ability of perennial polycultures to support ecosystem services when used in crop rotations is quantified through eight agricultural ecosystem services. Legume-grass mixtures and wildflower mixtures are used as examples of perennial polycultures, and compared with silage maize as a typical crop for biomass production. Perennial polycultures enhance soil fertility, soil protection, climate regulation, pollination, pest and weed control, and landscape aesthetics compared with maize. They also score lower for biomass production compared with maize, which confirms the trade-off between provisioning and regulating ecosystem services. However, the additional positive factors provided by perennial polycultures, such as reduced costs for mineral fertilizer, pesticides, and soil tillage, and a significant preceding crop effect that increases the yields of subsequent crops, should be taken into account. However, a full assessment of agricultural ecosystem services requires a more holistic analysis that is beyond the capabilities of current frameworks.

Caffeine, a potent free radical scavenger and adenosine receptor antagonist, reduces rates of brain damage in preterm infants. In the present study, we investigated the effects of caffeine on oxidative stress markers, anti-oxidative response, inflammation, redox-sensitive transcription factors, apoptosis, and extracellular matrix following the induction of hyperoxia in neonatal rats. The brain of a rat pups at postnatal Day 6 (P6) corresponds to that of a human fetal brain at 28–32 weeks gestation and the neonatal rat is an ideal model in which to investigate effects of oxidative stress and neuroprotection of caffeine on the developing brain. Six-day-old Wistar rats were pre-treated with caffeine and exposed to 80% oxygen for 24 and 48 h. Caffeine reduced oxidative stress marker (heme oxygenase-1, lipid peroxidation, hydrogen peroxide, and glutamate-cysteine ligase catalytic subunit (GCLC)), promoted anti-oxidative response (superoxide dismutase, peroxiredoxin 1, and sulfiredoxin 1), down-regulated pro-inflammatory cytokines, modulated redox-sensitive transcription factor expression (Nrf2/Keap1, and NFκB), reduced pro-apoptotic effectors (poly (ADP-ribose) polymerase-1 (PARP-1), apoptosis inducing factor (AIF), and caspase-3), and diminished extracellular matrix degeneration (matrix metalloproteinases (MMP) 2, and inhibitor of metalloproteinase (TIMP) 1/2). Our study affirms that caffeine is a pleiotropic neuroprotective drug in the developing brain due to its anti-oxidant, anti-inflammatory, and anti-apoptotic properties.

Potential factors in its success are temperature, light and nutrient levels. Grazing losses through zooplankton have been measured in the laboratory but are typically not regarded as a factor in (failed) invasion success. In some potentially suitable lakes, C. raciborskii has never been found, although it is present in water bodies close by. Therefore, we tested the invasive potential of three different isolates introduced into natural plankton communities using laboratory mesocosm experiments under three grazing levels: ambient zooplankton densities, removal of large species using 100 mu m mesh and a ca. doubling of large species. Three C. raciborskii isolates originating from the same geographic region (North-East Germany) were added separately to the four replicates of each treatment and kept in semi-continuous cultures for 21 days. Two isolates disappeared from the mesocosms and were also not viable in filtered lake water indicating that the lake water itself or the switch from culture medium to lake water led to the decay of the inoculated C. raciborskii. Only one out of the three isolates persisted in the plankton communities at a rather low level and only in the treatment without larger zooplankton. This result demonstrates that under potentially suitable environmental conditions, top-down control from zooplankton might hamper the establishment of C. raciborskii. Non-metric multidimensional scaling showed distinct variation in resident phytoplankton communities between the different grazing levels, thus differential grazing impact shaped the resident community in different ways allowing C. raciborskii only to invade under competitive (= low grazing pressure) conditions. Furthermore, even after invasion failure, the temporary presence of C. raciborskii influenced the phytoplankton community.

This makes it difficult to compare results from different studies and to explore the relationship between SES and health outcomes. To aid researchers in choosing appropriate indicators of SES, this article proposes and tests a theory-based selection of SES indicators using chronic back pain as a health outcome. Results: Chronic back pain intensity was best predicted by the multidimensional index (beta = 0.31, p < 0.05), followed by job position (beta = 0.29, p < 0.05) and education (beta = -0.29, p < 0.05); whereas, income exerted no significant influence. Back pain disability was predicted strongest by education (beta = -0.30, p < 0.05) and job position (beta = 0. 29, p < 0.05). Here, multidimensional index and income had no significant influence. Conclusions: The choice of SES indicators influences predictive power on both back pain dimensions, suggesting SES predictors cannot be used interchangeably. Therefore, researchers should carefully consider prior to each study which SES indicator to use. The introduced framework can be valuable in supporting this decision because it allows for a stable prediction of SES indicator influence and their hierarchy on a specific health outcomes.

Their internal organs can be found in the collections of the Natural History Museum of Denmark, but the location of their skins has remained a mystery. In 1999, Great Auk expert Errol Fuller proposed a list of five potential candidate skins in museums around the world. Here we take a palaeogenomic approach to test which—if any—of Fuller’s candidate skins likely belong to either of the two birds. Using mitochondrial genomes from the five candidate birds (housed in museums in Bremen, Brussels, Kiel, Los Angeles, and Oldenburg) and the organs of the last two known individuals, we partially solve the mystery that has been on Great Auk scholars’ minds for generations and make new suggestions as to the whereabouts of the still-missing skin from these two birds.

Among the parasites and pathogens threatening health and survival of honey bees are two species of microsporidia, Nosema apis and Nosema ceranae. Nosema ceranae is considered an emerging pathogen of the Western honey bee. Reports on the spread of N. ceranae suggested that this presumably highly virulent species is replacing its more benign congener N. apis in the global A. mellifera population. We here present a 12 year longitudinal cohort study on the prevalence of N. apis and N. ceranae in Northeast Germany. Between 2005 and 2016, a cohort of about 230 honey bee colonies originating from 23 apiaries was sampled twice a year (spring and autumn) resulting in a total of 5,600 bee samples which were subjected to microscopic and molecular analysis for determining the presence of infections with N. apis or/and N. ceranae. Throughout the entire study period, both N. apis- and N. ceranae-infections could be diagnosed within the cohort. Logistic regression analysis of the prevalence data demonstrated a significant increase of N. ceranae-infections over the last 12 years, both in autumn (reflecting the development during the summer) and in spring (reflecting the development over winter) samples. Cell culture experiments confirmed that N. ceranae has a higher proliferative potential than N. apis at 27. and 33 degrees C potentially explaining the increase in N. ceranae prevalence during summer. In autumn, characterized by generally low infection prevalence, this increase was accompanied by a significant decrease in N. apis- infection prevalence. In contrast, in spring, the season with a higher prevalence of infection, no significant decrease of N. apis infections despite a significant increase in N. ceranae infections could be observed. Therefore, our data do not support a general advantage of N. ceranae over N. apis and an overall replacement of N. apis by N. ceranae in the studied honey bee population.

Usually, this process can only be investigated spectroscopically as long as there exists electron correlation between the photofragments. Important parameters, like their kinetic energy after separation, cannot be investigated. We are reporting on a femtosecond time-resolved Auger electron spectroscopy study concerning the photofragmentation dynamics of thymine. We observe the appearance of clearly distinguishable signatures from thymines neutral photofragment isocyanic acid. Furthermore, we observe a time-dependent shift of its spectrum, which we can attribute to the influence of the charged fragment on the Auger electron. This allows us to map our time-dependent dataset onto the fragmentation coordinate. The time dependence of the shift supports efficient transformation of the excess energy gained from photoionization into kinetic energy of the fragments. Our method is broadly applicable to the investigation of photofragmentation processes.

The time dependent curves were found to be delayed with respect to solar radiation, sap flow activity, temperature and vapor pressure deficit. A general equation for the potential difference was derived and simplified by analyzing the effect of temperature and tensile strength. The potential determining influence of oxygen concentration on the respective location of the platinum electrode was identified as the principal phenomenon measured.

The main goal of this paper is to argue for the realizability of the moral ideal by means of the principle of reflective judgment as a form of judgment that in fact clarifies human limitation. I assert that the very recognition of this limitation constitutes the possibility for hope in that ideal, or for striving towards it, and that this striving is the only way that the moral ideal can be concretized. I examine man’s recognition of self-limitation as a response to the moral demand to realize the moral ideal and the necessity of the power of imagination for this, used reflectively.

The relationship between lutein accumulation and egg yolk colouration was therefore studied in more detail. After feeding a low-luteine diet for 21 days, 14 birds (Lohmann brown hens aged 20 weeks) were fed a diet containing marigold (80 mg lutein/kg feed) and 14 other birds were fed a diet containing oleoresin (45 mg lutein/kg feed) for 21 days; for both groups of birds, this feeding period was followed by withdrawal for 21 days. The Roche Yolk Colour Fan (RYCF) score (0 to 15, where higher values denote greater colour intensity; R-2=0.87; P<0.01) and redness (R-2=0.89; P<0.01) increased with increasing lutein content of egg yolk. Total carotenoid content had a poor relationship with lightness (R-2=0.13; P>0.05) and yellowness (R-2=0.12; P>0.05) of the yolk. It may be concluded that increased lutein is potentially responsible for an increased RYCF score and redness (a*), but decreased yellowness (b*) and lightness (L*), of egg yolk.

The United Nations REDD Programme (UN-REDD) is training governments in developing countries, including Nigeria, to implement REDD+. To protect local people, UN-REDD has developed social safeguards including a commitment to strengthen local democracy to prevent an elite capture of REDD+ benefits. This study examines local participation and representation in the UN-REDD international policy board and in the national-level design process for the Nigeria-REDD proposal, to see if practices are congruent with the UN-REDD commitment to local democracy. It is based on research in Nigeria in 2012 and 2013, and finds that local representation in the UN-REDD policy board and in Nigeria-REDD is not substantive. Participation is merely symbolic. For example, elected local government authorities, who ostensibly represent rural people, are neither present in the UN-REDD board nor were they invited to the participatory forums that vetted the Nigeria-REDD. They were excluded because they were politically weak. However, UN-REDD approved the Nigeria-REDD proposal without a strategy to include or strengthen elected local governments. The study concludes with recommendations to help the UN-REDD strengthen elected local government authority in Nigeria in support of democratic local representation.

T1 - ecoAO BT - a simple system for the study of human aldehyde oxidases role in drug metabolism JF - ACS OMEGA N2 - Although aldehyde oxidase (AO) is an important hepatic drug-metabolizing enzyme, it remains understudied and is consequently often overlooked in preclinical studies, an oversight that has resulted in the failure of multiple clinical trials. AO’s preclusion to investigation stems from the following: (1) difficulties synthesizing metabolic standards due to the chemospecificity and regiospecificity of the enzyme and (2) significant inherent variability across existing in vitro systems including liver cytosol, S9 fractions, and primary hepatocytes, which lack specificity and generate discordant expression and activity profiles. Here, we describe a practical bacterial biotransformation system, ecoAO, addressing both issues simultaneously. ecoAO is a cell paste of MoCo-producing Escherichia coli strain TP1017 expressing human AO. It exhibits specific activity toward known substrates, zoniporide, 4-trans-(N,N-dimethylamino)cinnamaldehyde, O6-benzylguanine, and zaleplon; it also has utility as a biocatalyst, yielding milligram quantities of synthetically challenging metabolite standards such as 2-oxo-zoniporide. Moreover, ecoAO enables routine determination of kcat and V/K, which are essential parameters for accurate in vivo clearance predictions. Furthermore, ecoAO has potential as a preclinical in vitro screening tool for AO activity, as demonstrated by its metabolism of 3-aminoquinoline, a previously uncharacterized substrate. ecoAO promises to provide easy access to metabolites with the potential to improve pharmacokinetic clearance predictions and guide drug development.

They allow the detection of directional changes in community dynamics and ecosystemic processes, being an additional tool to assess biodiversity than species richness. Analysis of functional patterns in plant communities provides mechanistic insight into biodiversity alterations due to anthropogenic activity. Although studies have consi-dered of either anthropogenic management or nutrient availability on functional traits in temperate grasslands, studies combining effects of both drivers are scarce. Here, we assessed the impacts of management intensity (fertilization, mowing, grazing), nutrient stoichiometry (C, N, P, K), and vegetation composition on community-weighted means (CWMs) and functional diversity (Rao's Q) from seven plant traits in 150 grasslands in three regions in Germany, using data of 6 years. Land use and nutrient stoichiometry accounted for larger proportions of model variance of CWM and Rao's Q than species richness and productivity. Grazing affected all analyzed trait groups; fertilization and mowing only impacted generative traits. Grazing was clearly associated with nutrient retention strategies, that is, investing in durable structures and production of fewer, less variable seed. Phenological variability was increased. Fertilization and mowing decreased seed number/mass variability, indicating competition-related effects. Impacts of nutrient stoichiometry on trait syndromes varied. Nutrient limitation (large N:P, C:N ratios) promoted species with conservative strategies, that is, investment in durable plant structures rather than fast growth, fewer seed, and delayed flowering onset. In contrast to seed mass, leaf-economics variability was reduced under P shortage. Species diversity was positively associated with the variability of generative traits. Synthesis. Here, land use, nutrient availability, species richness, and plant functional strategies have been shown to interact complexly, driving community composition, and vegetation responses to management intensity. We suggest that deeper understanding of underlying mechanisms shaping community assembly and biodiversity will require analyzing all these parameters.

In recent years, chromatin modifications, nucleosome positioning, and DNA methylation have been recognized as important components in these adaptations. Given their potential epigenetic nature, such modifications may provide a mechanistic basis for a stress memory, enabling plants to respond more efficiently to recurring stress or even to prepare their offspring for potential future assaults. In this review, we discuss both the involvement of chromatin in stress responses and the current evidence on somatic, intergenerational, and transgenerational stress memory.

Mineralization was performed between pH 6 and 9 and with NTA or EDTA concentrations of 0, 5, 10, and 15 mM. X-ray diffraction and infrared spectroscopy show that at low pH, mainly brushite precipitates and at higher pH, mostly hydroxyapatite forms. Both additives alter the morphology of the precipitates. Without additive, brushite precipitates as large plates. With NTA, the morphology changes to an unusual rod-like shape. With EDTA, the edges of the particles are rounded and disk-like particles form. Conductivity and pH measurements suggest that the final products form through several intermediate steps.

However, most countries still focus their efforts on responding to flooding events if and when they occur rather than addressing their current and future vulnerability to flooding. Flood insurance is one mechanism that could promote a more ex ante approach to risk by supporting risk reduction activities. This paper uses an adapted version of Easton's System Theory to investigate the role of insurance for FRM in Germany and England. We introduce an anticipatory FRM framework, which allows flood insurance to be considered as part of a broader policy field. We analyze if and how flood insurance can catalyze a change toward a more anticipatory approach to FRM. In particular we consider insurance's role in influencing five key components of anticipatory FRM: risk knowledge, prevention through better planning, property‐level protection measures, structural protection and preparedness (for response). We find that in both countries FRM is still a reactive, event‐driven process, while anticipatory FRM remains underdeveloped. Collaboration between insurers and FRM decision‐makers has already been successful, for example in improving risk knowledge and awareness, while in other areas insurance acts as a disincentive for more risk reduction action. In both countries there is evidence that insurance can play a significant role in encouraging anticipatory FRM, but this remains underutilized. Effective collaboration between insurers and government should not be seen as a cost, but as an investment to secure future insurability through flood resilience.
