In 2001 and 2002, a survey with special emphasis oil virus isolation in migrating waders and some other birds were conducted. In one of the most important inland resting sites for migratory waterfowl, tracheal and cloacal swabs were collected from 465 waders representing 19 different species, and 165 other birds that were not captured on purpose. A total of 42 avian viruses were isolated, 34 of these were identified as paramyxoviruses (PMVs). The majority of isolates came from waders and wild ducks, and were characterized as PMV-1. In contrast, PMV-4 was found in wild ducks only, PMV-6 was mainly detected in wader species. Four avian influenza viruses (ATVs), belonging to H4 and H3 haemagglutinin subtype, were isolated from wild duck species. Furthermore, four reo-like viruses were isolated from one particular wader species for the first time. The majority of virus positive birds were < 1 year old and did not show any clinical symptoms. There was no evidence for the presence of West Nile virus in these birds. These results confirm that the restricted resting sites in Western Europe must be considered as important locations for the intra- and interspecies transmission of avian viruses Y1 - 2006 SN - 0931-1793 ER - TY - GEN A1 - Rolinski, Susanne A1 - Rammig, Anja A1 - Walz, Ariane A1 - von Bloh, Werner A1 - van Oijen, M. A1 - Thonicke, Kirsten T1 - A probabilistic risk assessment for the vulnerability of the European carbon cycle to weather extremes BT - The ecosystem perspective T2 - Postprints der Universität Potsdam : Mathematisch naturwissenschaftliche Reihe (487) N2 - Extreme weather events are likely to occur more often under climate change and the resulting effects on ecosystems could lead to a further acceleration of climate change. But not all extreme weather events lead to extreme ecosystem response. Here, we focus on hazardous ecosystem behaviour and identify coinciding weather conditions. We use a simple probabilistic risk assessment based on time series of ecosystem behaviour and climate conditions. Given the risk assessment terminology, vulnerability and risk for the previously defined hazard are estimated on the basis of observed hazardous ecosystem behaviour. We apply this approach to extreme responses of terrestrial ecosystems to drought, defining the hazard as a negative net biome productivity over a 12-month period. We show an application for two selected sites using data for 1981-2010 and then apply the method to the pan-European scale for the same period, based on numerical modelling results (LPJmL for ecosystem behaviour; ERA-Interim data for climate). Our site-specific results demonstrate the applicability of the proposed method, using the SPEI to describe the climate condition. The site in Spain provides an example of vulnerability to drought because the expected value of the SPEI is 0.4 lower for hazardous than for non-hazardous ecosystem behaviour. In northern Germany, on the contrary, the site is not vulnerable to drought because the SPEI expectation values imply wetter conditions in the hazard case than in the non-hazard case. At the pan-European scale, ecosystem vulnerability to drought is calculated in the Mediterranean and temperate region, whereas Scandinavian ecosystems are vulnerable under conditions without water shortages. These first model- based applications indicate the conceptual advantages of the proposed method by focusing on the identification of critical weather conditions for which we observe hazardous ecosystem behaviour in the analysed data set. Application of the method to empirical time series and to future climate would be important next steps to test the approach.

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.
