To safeguard the sustainable use of ecosystems and their services, early detection of potentially damaging changes in functional capabilities is needed. To support a proper ecosystem management, the analysis of an ecosystem’s vulnerability provide information on its weaknesses as well as on its capacity to recover after suffering an impact. However, the application of the vulnerability concept to ecosystems is still an emerging topic. After providing background on the vulnerability concept, we summarize existing ecosystem vulnerability research on the basis of a systematic literature review with a special focus on ecosystem type, disciplinary background, and more detailed definition of the ecosystem vulnerability components. Using the Web of ScienceTM Core Collection, we overviewed the literature from 1991 onwards but used the 5 years from 2011 to 2015 for an in-depth analysis, including 129 articles. We found that ecosystem vulnerability analysis has been applied most notably in conservation biology, climate change research, and ecological risk assessments, pinpointing a limited spreading across the environmental sciences. It occurred primarily within marine and freshwater ecosystems. To avoid confusion, we recommend using the unambiguous term ecosystem vulnerability rather than ecological, environmental, population, or community vulnerability. Further, common ground has been identified, on which to define the ecosystem vulnerability components exposure, sensitivity, and adaptive capacity. We propose a framework for ecosystem assessments that coherently connects the concepts of vulnerability, resilience, and adaptability as different ecosystem responses. A short outlook on the possible operationalization of the concept by ecosystem vulnerabilty indices, and a conclusion section complete the review.
Seit dem 01. 04. 2017 erfolgte eine umfangreiche Reform der Psychotherapie-Richtlinie. Neben der Einführung neuer Leistungen (z. B. Akutbehandlung, psychotherapeutische Sprechstunde) wurden auch Änderungen im Ablauf und der Beantragung von Psychotherapie beschlossen. Beispielsweise ist der Bericht an den Gutachter bzw. die Gutachterin seltener eine notwendige Voraussetzung zur Durchführung einer psychotherapeutischen Behandlung, als dass zuvor der Fall war. Im Zuge der Reform wurde auch der Leitfaden für die Gestaltung des Berichts an den Gutachter bzw. die Gutachterin überarbeitet.
Vor dem Hintergrund der Psychotherapie-Richtlinien-Reform ist das Werk „Leitfaden für den VT-Bericht an den Gutachter“ von Daniel Surall und Oliver Kunz sehr willkommen. Das Buch gliedert sich insgesamt in zehn Kapitel, in denen die Autoren ausführlich auf den reformierten Bericht an den Gutachter bzw. an die Gutachterin eingehen. In den ersten beiden Kapiteln fassen die Autoren die Änderungen zur Psychotherapie-Richtlinie und im Bericht an den Gutachter / die Gutachterin zusammen. In den folgenden sechs Kapiteln wird auf die einzelnen Abschnitte des neuen Berichts an den Gutachter/die Gutachterin eingegangen. Sehr hilfreich ist hierbei, dass die Autoren zahlreiche Fallbeispiele nutzen, um die einzelnen Abschnitte des Berichts an den Gutachter/die Gutachterin zu erläutern. Auch die übersichtliche Darstellungsform in Form von Tabellen (z. B. zur Darstellung der Verhaltensanalyse) erleichtert den Leser_innen die Nachvollziehbarkeit der Inhalte. Erfreulich ist auch, dass die Autoren hinsichtlich der Antragstellung auch immer auf Unterschiede zwischen erwachsenen Patient_innen und Kindern und Jugendlichen eingehen. Im neunten Kapitel des Leitfadens wird ausführlicher das Thema Umwandlungs- und Fortführungsanträge aufgegriffen. Dies ist insbesondere sinnvoll, da nach der neuen Psychotherapie-Richtlinie für Kurzzeitanträge in der Regel keine Berichtspflicht besteht und Umwandlungs- und Fortführungsanträge in der Praxis häufiger als zuvor von Relevanz sein dürften. Im zehnten Kapitel wird in knapper Weise darauf eingegangen, wie bei Ablehnung oder Kürzung von beantragten Leistungen vorgegangen werden kann.
Das Buch umfasst einen umfangreichen Anhang (67 Seiten), in dem Beispiele für Berichte an den Gutachter / die Gutachterin und Behandlungspläne für verschiedene psychische Störungen zu finden sind. Auch hierbei werden sowohl Berichte für Erwachsene als auch für Kinder und Jugendliche präsentiert. Zudem beinhaltet der Anhang des Buches das Berner Inventar für Therapieziele, Auszüge aus dem AMDP-Befundbogen (Arbeitsgemeinschaft Methodik und Dokumentation in der Psychiatrie, 2018)<\litr>, den Leitfaden zum Erstellen des Berichts an die Gutachter_innen (PTV 3) sowie einer Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an die Gutachter_innen.
Bei dem von Surall und Kunz vorgelegten Buch handelt es sich um einen äußerst hilfreichen Leitfaden, der Therapeut:innen bei der Abfassung des Berichts an den Gutachter / die Gutachterin im Rahmen der Verhaltenstherapie unterstützen kann. Hierbei kann der Leitfaden Psychotherapeut_innen in Ausbildung bei der Abfassung ihrer ersten Anträge unterstützen. Aber auch erfahrenen Kolleg_innen können bei dem Übergang in die neuen Antragsformalitäten, die mit der Reform der Psychotherapie-Richtlinie einhergingen, unterstützen werden. Hierbei ist insbesondere die Im Anhang befindliche Gegenüberstellung des alten und des neuen Leitfadens für den Bericht an den Gutachter / die Gutachterin hilfreich, um sich einen schnellen Überblick über die Änderungen zu verschaffen. Insgesamt werden die einzelnen Abschnitte des Berichts an den Gutachter / die Gutachterin sehr gut strukturiert und verständlich erläutert. Die vielen Beispiele und die ausführlichen Materialien im Anhang ergänzen zudem die Erläuterungen und erleichtern das Verständnis. Zu Beginn des Buches wäre zudem noch eine Abbildung hilfreich gewesen, die den Ablauf der Beantragung von Psychotherapie schematisch darstellt, um einen genaueren Überblick über die Beantragung von Psychotherapie nach der neuen Psychotherapie-Richtlinie zu erhalten. Auch ein Stichwortverzeichnis würde die Suche nach bestimmten Inhalten erleichtern.
Zusammenfassend kann festgehalten werden, dass es sich bei dem Werk von Surall und Kunz um einen sehr empfehlenswerten Leitfaden handelt, der im Rahmen der Antragstellung von Verhaltenstherapie genutzt werden kann. Aufgrund der klaren Struktur und Anschaulichkeit durch viele Beispielanträge bringt das Buch alle Voraussetzungen mit, um sich als Standartwerk zu etablieren, dass Therapeut_innen bei der Beantragung von Verhaltenstherapie in äußerst hilfreicher Weise unterstützt.

Islands as model systems in ecology and evolution: prospects fifty years after MacArthur-Wilson
(2015)
The study of islands as model systems has played an important role in the development of evolutionary and ecological theory. The 50th anniversary of MacArthur and Wilson's (December 1963) article, An equilibrium theory of insular zoogeography', was a recent milestone for this theme. Since 1963, island systems have provided new insights into the formation of ecological communities. Here, building on such developments, we highlight prospects for research on islands to improve our understanding of the ecology and evolution of communities in general. Throughout, we emphasise how attributes of islands combine to provide unusual research opportunities, the implications of which stretch far beyond islands. Molecular tools and increasing data acquisition now permit re-assessment of some fundamental issues that interested MacArthur and Wilson. These include the formation of ecological networks, species abundance distributions, and the contribution of evolution to community assembly. We also extend our prospects to other fields of ecology and evolution - understanding ecosystem functioning, speciation and diversification - frequently employing assets of oceanic islands in inferring the geographic area within which evolution has occurred, and potential barriers to gene flow. Although island-based theory is continually being enriched, incorporating non-equilibrium dynamics is identified as a major challenge for the future.

The nutrition of animal consumers is an important regulator of ecological processes due to its effects on their physiology, life-history and behaviour. Understanding the ecological effects of poor nutrition depends on correctly diagnosing the nature and strength of nutritional limitation. Despite the need to assess nutritional limitation, current approaches to delineating nutritional constraints can be non-specific and imprecise. Here, we consider the need and potential to develop new complementary approaches to the study of nutritional constraints on animal consumers by studying and using a suite of established and emerging biochemical and molecular responses. These nutritional indicators include gene expression, transcript regulators, protein profiling and activity, and gross biochemical and elemental composition. The potential applications of nutritional indicators to ecological studies are highlighted to demonstrate the value that this approach would have to future studies in community and ecosystem ecology.

Purpose of reviewIncretin-based therapy with glucagon-like peptide-1 receptor (GLP-1R) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors is considered a promising therapeutic option for type 2 diabetes mellitus. Cumulative evidence, mainly from preclinical animal studies, reveals that incretin-based therapies also may elicit beneficial effects on kidney function. This review gives an overview of the physiology, pathophysiology, and pharmacology of the renal incretin system.Recent findingsActivation of GLP-1R in the kidney leads to diuretic and natriuretic effects, possibly through direct actions on renal tubular cells and sodium transporters. Moreover, there is evidence that incretin-based therapy reduces albuminuria, glomerulosclerosis, oxidative stress, and fibrosis in the kidney, partially through GLP-1R-independent pathways. Molecular mechanisms by which incretins exert their renal effects are understood incompletely, thus further studies are needed.SummaryThe GLP-1R and DPP-4 are expressed in the kidney in various species. The kidney plays an important role in the excretion of incretin metabolites and most GLP-1R agonists and DPP-4 inhibitors, thus special attention is required when applying incretin-based therapy in renal impairment. Preclinical observations suggest direct renoprotective effects of incretin-based therapies in the setting of hypertension and other disorders of sodium retention, as well as in diabetic and nondiabetic nephropathy. Clinical studies are needed in order to confirm translational relevance from preclinical findings for treatment options of renal diseases.

Malnutrition is widespread in older people and represents a major geriatric syndrome with multifactorial etiology and severe consequences for health outcomes and quality of life. The aim of the present paper is to describe current approaches and evidence regarding malnutrition treatment and to highlight relevant knowledge gaps that need to be addressed. Recently published guidelines of the European Society for Clinical Nutrition and Metabolism (ESPEN) provide a summary of the available evidence and highlight the wide range of different measures that can be taken—from the identification and elimination of potential causes to enteral and parenteral nutrition—depending on the patient’s abilities and needs. However, more than half of the recommendations therein are based on expert consensus because of a lack of evidence, and only three are concern patient-centred outcomes. Future research should further clarify the etiology of malnutrition and identify the most relevant causes in order to prevent malnutrition. Based on limited and partly conflicting evidence and the limitations of existing studies, it remains unclear which interventions are most effective in which patient groups, and if specific situations, diseases or etiologies of malnutrition require specific approaches. Patient-relevant outcomes such as functionality and quality of life need more attention, and research methodology should be harmonised to allow for the comparability of studies.

Setting the PAS, the role of circadian PAS domain proteins during environmental adaptation in plants
(2015)
The per-ARNT-sim (PAS) domain represents an ancient protein module that can be found across all kingdoms of life. The domain functions as a sensing unit for a diverse array of signals, including molecular oxygen, small metabolites, and light. In plants, several PAS domain-containing proteins form an integral part of the circadian clock and regulate responses to environmental change. Moreover, these proteins function in pathways that control development and plant stress adaptation responses. Here, we discuss the role of PAS domain-containing proteins in anticipation, and adaptation to environmental changes in plants.

Eye movement data have proven to be very useful for investigating human sentence processing. Eyetracking research has addressed a wide range of questions, such as recovery mechanisms following garden-pathing, the timing of processes driving comprehension, the role of anticipation and expectation in parsing, the role of semantic, pragmatic, and prosodic information, and so on. However, there are some limitations regarding the inferences that can be made on the basis of eye movements. One relates to the nontrivial interaction between parsing and the eye movement control system which complicates the interpretation of eye movement data. Detailed computational models that integrate parsing with eye movement control theories have the potential to unpack the complexity of eye movement data and can therefore aid in the interpretation of eye movements. Another limitation is the difficulty of capturing spatiotemporal patterns in eye movements using the traditional word-based eyetracking measures. Recent research has demonstrated the relevance of these patterns and has shown how they can be analyzed. In this review, we focus on reading, and present examples demonstrating how eye movement data reveal what events unfold when the parser runs into difficulty, and how the parsing system interacts with eye movement control.

Sentence comprehension requires that the comprehender work out who did what to whom. This process has been characterized as retrieval from memory. This review summarizes the quantitative predictions and empirical coverage of the two existing computational models of retrieval and shows how the predictive performance of these two competing models can be tested against a benchmark data-set. We also show how computational modeling can help us better understand sources of variability in both unimpaired and impaired sentence comprehension.
The importance of carbohydrate chemistry in biological and medicinal chemistry has led to enormous developments in the synthesis of carbohydrate mimics. In this context, the synthesis of branched sugars in general and of 2-C-branched carbohydrates in particular, as well as the synthesis of 1,2-annulated sugars, have received immense attention. They serve not only as carbohydrate mimics in the form of stand-alone molecules, but also as useful intermediates in the synthesis of many natural products, their analogues, and glycosidase inhibitors. This microreview covers the recent synthetic efforts in this area and puts the subject matter into proper perspective for future developments.

Plans are currently being drafted for the next decade of action on biodiversity-both the post-2020 Global Biodiversity Framework of the Convention on Biological Diversity (CBD) and Biodiversity Strategy of the European Union (EU). Freshwater biodiversity is disproportionately threatened and underprioritized relative to the marine and terrestrial biota, despite supporting a richness of species and ecosystems with their own intrinsic value and providing multiple essential ecosystem services. Future policies and strategies must have a greater focus on the unique ecology of freshwater life and its multiple threats, and now is a critical time to reflect on how this may be achieved. We identify priority topics including environmental flows, water quality, invasive species, integrated water resources management, strategic conservation planning, and emerging technologies for freshwater ecosystem monitoring. We synthesize these topics with decades of first-hand experience and recent literature into 14 special recommendations for global freshwater biodiversity conservation based on the successes and setbacks of European policy, management, and research. Applying and following these recommendations will inform and enhance the ability of global and European post-2020 biodiversity agreements to halt and reverse the rapid global decline of freshwater biodiversity.
Particle filters contain the promise of fully nonlinear data assimilation. They have been applied in numerous science areas, including the geosciences, but their application to high-dimensional geoscience systems has been limited due to their inefficiency in high-dimensional systems in standard settings. However, huge progress has been made, and this limitation is disappearing fast due to recent developments in proposal densities, the use of ideas from (optimal) transportation, the use of localization and intelligent adaptive resampling strategies. Furthermore, powerful hybrids between particle filters and ensemble Kalman filters and variational methods have been developed. We present a state-of-the-art discussion of present efforts of developing particle filters for high-dimensional nonlinear geoscience state-estimation problems, with an emphasis on atmospheric and oceanic applications, including many new ideas, derivations and unifications, highlighting hidden connections, including pseudo-code, and generating a valuable tool and guide for the community. Initial experiments show that particle filters can be competitive with present-day methods for numerical weather prediction, suggesting that they will become mainstream soon.
Purpose
The purpose of this paper is to investigate whether and how evolving ideas about management control (MC) emerge in research about public sector performance management (PSPM).
Design/methodology/approach
This is a literature review on PSPM research through using a set of key terms derived from a review of recent developments in MC.
Findings
MC research, originating in the management accounting discipline, is largely disconnected from PSPM research as part of public administration and public management disciplines. Overlaps between MC and PSPM research are visible in a cybernetic control approach, control variety and contingency-based reasoning. Both academic communities share an understanding of certain issues, although under diverging labels, especially enabling controls or, in a more general sense, usable performance controls, horizontal controls and control packaging. Specific MC concepts are valuable for future PSPM research, i.e. trust as a complement of performance-based controls in complex settings, and strategy as a variable in contingency-based studies.
Research limitations/implications
Breaking the boundaries between two currently remote research disciplines, on the one hand, might dismantle “would-be” innovations in one of these disciplines, and, on the other hand, may provide a fertile soil for mutual transfer of knowledge. A limitation of the authors’ review of PSPM research is that it may insufficiently cover research published in the public sector accounting journals, which could be an outlet for MC-inspired PSPM research.
Originality/value
The paper unravels the “apparent” and “real” differences between MC and PSPM research, and, in doing so, takes the detected “real” differences as a starting point for discussing in what ways PSPM research can benefit from MC achievements.
Many organisms have developed defences to avoid predation by species at higher trophic levels. The capability of primary producers to defend themselves against herbivores affects their own survival, can modulate the strength of trophic cascades and changes rates of competitive exclusion in aquatic communities. Algal species are highly flexible in their morphology, growth form, biochemical composition and production of toxic and deterrent compounds. Several of these variable traits in phytoplankton have been interpreted as defence mechanisms against grazing. Zooplankton feed with differing success on various phytoplankton species, depending primarily on size, shape, cell wall structure and the production of toxins and deterrents. Chemical cues associated with (i) mechanical damage, (ii) herbivore presence and (iii) grazing are the main factors triggering induced defences in both marine and freshwater phytoplankton, but most studies have failed to disentangle the exact mechanism(s) governing defence induction in any particular species. Induced defences in phytoplankton include changes in morphology (e.g. the formation of spines, colonies and thicker cell walls), biochemistry (such as production of toxins, repellents) and in life history characteristics (formation of cysts, reduced recruitment rate). Our categorization of inducible defences in terms of the responsible induction mechanism provides guidance for future work, as hardly any of the available studies on marine or freshwater plankton have performed all the treatments that are required to pinpoint the actual cue(s) for induction. We discuss the ecology of inducible defences in marine and freshwater phytoplankton with a special focus on the mechanisms of induction, the types of defences, their costs and benefits, and their consequences at the community level.
The identification of buried soil horizons in agricultural landscapes helps to quantify sediment budgets and erosion-related carbon dynamics. High-resolution mapping of buried horizons using conventional soil surveys is destructive and time consuming. Geoelectrical sensors can offer a fast and non-destructive alternative for determining horizon positions and properties. In this paper, we compare the suitability of several geoelectrical methods for measuring the depth to buried horizons (Apb, Ahb and Hab) in the hummocky ground moraine landscape of northeastern Germany. Soil profile descriptions were developed for 269 locations within a 6-ha experimental field "CarboZALF-D". A stepwise linear discriminant analysis (LDA) estimated the lateral position of the buried horizons using electromagnetic induction data and terrain attributes. To predict the depth of a buried horizon, multiple linear regression (MLR) was used for both a 120-m transect and a 0.2-ha pseudo-three-dimensional (3D) area. At these scales, apparent electrical conductivity (ECa), electrical resistivity (ER) and terrain attributes were used as independent variables. The LDA accurately predicted Apb- and Ahb-horizons (a correct classification of 93%). The LDA of the Hab-horizon had a misclassification of 24%, which was probably related to the smaller test set and the higher depth of this horizon. The MLR predicted the depth of the Apb-, Ahb- and Hab-horizons with relative root mean square errors (RMSEs) of 7, 3 and 13%, respectively, in the pseudo-3D area. MLR had a lower accuracy for the 2D transect compared to the pseudo-3D area. Overall, the use of LDA and MLR has been an efficient methodological approach for predicting buried horizon positions. Highlights The suitability of geoelectrical measurements for digital modelling of diagnostic buried soil horizons was determined. LDA and MLR were used to detect multiple horizons with geoelectrical devices and terrain attributes. Geoelectrical variables were significant predictors of the position of the target soil horizons. The use of these tested digital technologies gives an opportunity to develop high-resolution soil mapping procedures.
A class of adsorbents currently receiving growing attention is the clay-polymer nanocomposite (CPN) adsorbents. CPNs effectively treat water by adsorption and flocculation of both inorganic and organic micropollutants from aqueous solutions. Some of these CPNs - when modified with biocides - also have the ability to efficiently remove microorganisms such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans from water. CPNs are far more easily recovered from aqueous media than neat clay. They also exhibit far better treatment times than either polymer or clay adsorbents. They have higher adsorption capacity and better life cycles compared with clay alone. CPNs therefore show an excellent potential as highly efficient water and waste treatment agents.
This article reviews the various CPNs that have been prepared recently and used as adsorbents in the removal of micropollutants (inorganic, organic and biological) from aqueous solutions. A special focus is placed on CPNs that are not only interesting from an academic point of view but also effectively reduce the concentration of micropollutants in water to safe limits and also on new developments bordering on CPN use as water treatment agent that have not yet realized their full potential.

In eukaryotes, regulated protein turnover is required during many cellular processes, including defense against pathogens. Ubiquitination and degradation of ubiquitinated proteins via the ubiquitin proteasome system (UPS) is the main pathway for the turnover of intracellular proteins in eukaryotes. The extensive utilization of the UPS in host cells makes it an ideal pivot for the manipulation of cellular processes by pathogens. Like many other Gram-negative bacteria, Xanthomonas species secrete a suite of type-III effector proteins (T3Es) into their host cells to promote virulence. Some of these T3Es exploit the plant UPS to interfere with immunity. This review summarizes T3E examples from the genus Xanthomonas with a proven or suggested interaction with the host UPS or UPS-like systems and also discusses the apparent paradox that arises from the presence of T3Es that inhibit the UPS in general while others rely on its activity for their function.

Eye movements depend on cognitive processes related to visual information processing. Much has been learned about the spatial selection of fixation locations, while the principles governing the temporal control (fixation durations) are less clear. Here, we review current theories for the control of fixation durations in tasks like visual search, scanning, scene perception, and reading and propose a new model for the control of fixation durations. We distinguish two local principles from one global principle of control. First, an autonomous saccade timer initiates saccades after random time intervals (local-I). Second, foveal inhibition permits immediate prolongation of fixation durations by ongoing processing (local-II). Third, saccade timing is adaptive, so that the mean timer value depends on task requirements and fixation history (Global). We demonstrate by numerical simulations that our model qualitatively reproduces patterns of mean fixation durations and fixation duration distributions observed in typical experiments. When combined with assumptions of saccade target selection and oculomotor control, the model accounts for both temporal and spatial aspects of eye movement control in two versions of a visual search task. We conclude that the model provides a promising framework for the control of fixation durations in saccadic tasks.
We have isolated a cDNA coding for a putative invertebrate-type dopamine receptor (Peadop2) from P. americana brain by using a PCR-based strategy. The mRNA is present in samples from brain and salivary glands. We analyzed the distribution of the PeaDOP2 receptor protein with specific affinity-purified polyclonal antibodies. On Western blots, PeaDOP2 was detected in protein samples from brain, subesophageal ganglion, thoracic ganglia, and salivary glands. In immunocytochemical experiments, we detected PeaDOP2 in neurons with their somata being located at the anterior edge of the medulla bilaterally innervating the optic lobes and projecting to the ventro-lateral protocerebrum. In order to determine the functional and pharmacological properties of the cloned receptor, we generated a cell line constitutively expressing PeaDOP2. Activation of PeaDOP2-expressing cells with dopamine induced an increase in intracellular cAMP. In contrast, a C-terminally truncated splice variant of this receptor did not exhibit any functional property by itself. The molecular and pharmacological characterization of the first dopamine receptor from P. americana provides the basis for forthcoming studies focusing on the significance of the dopaminergic system in cockroach behavior and physiology.
The language situation in the Philipines between the many different native languages and English is complex. The book under review outlines the various contact situations, focussing on the contact between Tagalog, the most important indigenous language of the Philipines on the one hand and English on the other. This serves as the basis for a detailed discussion of the sociological determinasts of the contact continuum between Tagalog on the one hand and Standard English on the other. The main asset of the book is to be found in its well informed survey character resulting from personal teaching experience.
In previous research, the methodology of typological investigations into languages was based on the analysis of standard languages (or rather standardised written languages). Prof. Kortmann's collection of essays broadens this methodological scope by directing the scholars' typological interest to the traditional dialects, most of them transmitted orally only. Undoubtedly, there is a great potential in this effort. Most of the contributions in this volume, however, show, that the attempt to unify or perhaps rather to accommodate the methodologies of typological research and traditional dialectology needs to be further harmonised in future research in order to bear sound generalisable insights to the rich data available.
