Widespread insect losses are a critical global problem. Mitigating this problem requires identifying the principal drivers across different taxa and determining which insects are covered by protected areas. However, doing so is hindered by missing information on most species owing to extremely high insect diversity and difficulties in morphological...
Mitigating ongoing losses of insects and their key functions (e.g. pollination) requires tracking large‐scale and long‐term community changes. However, doing so has been hindered by the high diversity of insect species that requires prohibitively high investments of time, funding and taxonomic expertise when addressed with conventional tools. Here,...
Political responses to the COVID-19 pandemic led to changes in city soundscapes around the globe.From March to October 2020, a consortium of 261 contributors from 35 countries brought togetherby the Silent Cities project built a unique soundscape recordings collection to report on local acousticchanges in urban areas. We present this collection her...
The progressive loss of biodiversity in rivers and their floodplains has not yet been stopped. With the European Biodiversity Strategy and the goal of restoring at least 25,000 km of free‐flowing European rivers by 2030, the first important step has been taken. Now we need to be able to effectively demonstrate a reversal of biodiversity loss as wel...
Natural rivers offer riparian habitats to many highly specialised, rare, and endangered insect species and are extremely important for ecosystem services. In the past, these ecosystems have been heavily degraded by anthropogenic use and run the risk of losing their favourable ecological conditions. For this reason, restoration measures are urgently...
Over the last 40 years, a growing number of restoration projects have been implemented to improve the ecological conditions of highly degraded rivers and their floodplains. Despite considerable investment in these projects, information is still limited about the effectiveness and the success of such river restoration measures, mainly due to a lack...
• Among the many concerns for biodiversity in the Anthropocene, recent reports of flying insect loss are particularly alarming, given their importance as pollinators, pest control agents, and as a food source. Few insect monitoring programmes cover the large spatial scales required to provide more generalizable estimates of insect responses to glob...
A participatory monitoring programme of an exceptional modification of urban soundscapes during Covid-19 containment.
Near-natural rivers and riparian ecosystems can represent biodiversity hotspots harbouring many highly specialised, rare and endangered species. During the past centuries, these habitats have been heavily degraded by anthropogenic use, and therefore river restoration is one of the most striking fields of action that is legally defined by the Europe...
Von 325 für das Bundesland Sachsen-Anhalt nachgewiesene Schwebfliegen-Arten wurden insgesamt 100 einer der Gefährdungskategorien zugeordnet.

The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear...
Das Projekt Wilde Mulde verfolgt das Ziel mittels Einbringung von Raubäumen, der Wiederherstellung eines Naturufers und der Anbindung eines Seitenarms hydromorphologische Prozesse im Fluss und in angebundenen Altwässern zu initiieren. Ferner sollen eine nachhaltige Revitalisierung des Fluss-Auen-Ökosystems Untere Mulde und die Förderung seiner biol...
Restoration of ecosystems can mitigate the global loss of biodiversity and provide essential ecological functions and services. Although trait composition and functional diversity ( FD ) are important tools in assessing recovery processes, very few restoration projects use them to evaluate restoration success. Consequently, little is known about tr...
Um Auswirkungen des Klimawandels auf die biologische Vielfalt sowie die Effektivität von Strategien und Maßnahmen zu deren Minimierung darzustellen, sind geeignete Monitoring- und Indikatorensysteme zur Erfassung und Aufbereitung thematisch breit gefächerter Datenerforderlich. Für die Eignung der Indikatoren sind thematische Relevanz, ausreichende...
Der durch den Menschen verursachte Klimawandel führt bereits heute global und somit auch in Deutschland zu Veränderungen der biologischen Vielfalt. Diese werden sowohl durch direkte als auch indirekte Einflüsse des Klimawandels bestimmt. Direkte Wirkungen auf die biologische Vielfalt werden bspw. unmittelbar durch Änderungen der Temperatur- und Nie...
Die Fauna Indicativa charakterisiert in Tabellenform ökologische Präferenzen und biologische Eigen- schaften aller in der Schweiz einheimischen Libellen-, Heuschrecken-, Laufkäfer- und Tagfalterarten. Die Angaben für Präferenzen und Eigenschaften werden meist als Zahlen angegeben und entweder als skalierte Werte oder als Ja-Nein Entscheide aufgefüh...
The checklist of the hoverflies of Saxony-Anhalt includes 322 Species.
In the year 2010 cicadas (Auchenorrhyncha) were collected by standardised net catches (SCHIWORA 2011). With the presented study different fly families such as by-catches of the cicada investigation were evaluated. Alltogether four species of Asilidae, one in each case of Bombyliidae, Coenomyidae and Conopidae, three species in each case of Stratiom...
Dieser bislang umfassendste Bericht der Bundesregierung zur Anpassung an den Klimawandel zeigt: Steigende Temperaturen, feuchtere Winter und häufigere Wetterextreme wirken sich zunehmend auf die deutsche Gesellschaft aus. Betroffen sind unter anderem die Energieversorgung, die Landwirtschaft und die Gesundheitsvorsorge. Anhand von Daten aus 15 vers...
Analyses of species traits have increased our understanding of how environmental drivers such as disturbances affect the composition of arthropod communities and related processes. There are, however, few studies on which traits in the arthropod community are affected by environmental changes and which traits affect ecosystem functioning. The assem...
Bat activity is often concentrated near linear and edge landscape structures such as hedgerows, but information about seasonal and species-specific bat activity near hedges is scarce despite their abundance in the cultural landscapes of central Europe. Exact knowledge on animals' habitat use, however, is key to effective landscape planning to avoid...
Ecosystem functions and underlying services are strongly influenced by multitrophic relationships, with functional traits playing a central role in structuring them. Which traits and functional metrics mediate the impact of different types of land use on ecosystem function within and across trophic levels?
We studied the functional relationships be...
Integrated management of mosquitoes is becoming increasingly important, particularly in relation to avoiding recolonization of ponds after larvicide treatment. We conducted for the first time field experiments that involved exposing natural populations of the mosquito species Culex pipiens to: a) application of the biological insecticide Bacillus t...
Humans are rapidly reducing and isolating the habitats of native species such as the wheatear (Oenanthe oenanthe) through urbanisation and agricultural intensification. The wheatear, a small songbird, has declined dramatically throughout Europe. It is known to live in alpine meadows, in tundra, and rural landscapes as well as in urban areas, but it...
Bird species of cultivated landscapes have been declining dramatically for decades. The main cause for this decline is intensified agricultural practice. At the same time, worldwide urbanisation increases and has severe impacts on land use. Urban wastelands, i.e., unused land within urban agglomerations, are known to provide habitat for endangered...
Extreme environmental events are predicted to increase in future due to global climate change. However, their effects on biodiversity still remain insufficiently understood because of the rarity and consequently the difficulty of studying the effects of extreme events. Here, we investigate the impacts on ground beetles of an unpredictable catastrop...
Habitat templet theory predicts that habitat provides the templet on which evolution shapes species' multiple traits and thus their characteristic life-history strategies. By analysing entire trait communities (multiple species and traits) in this framework we can enhance our understanding of how species composition changes as environmental constra...
Aim To investigate whether trait–habitat relations in biological communities converge across three global regions. The goal is to assess the role of habitat templets in shaping trait assemblages when different assembly mechanisms are operating and to test whether trait–habitat relations reflect a common evolutionary history or environmental trait f...
The role of habitat disturbance on biodiversity is central as it promotes changes in ecological systems. That said, still little is known about the functional consequences of such changes. Functional diversity can be used to revealing more mechanistically the disturbance effects on communities by considering the richness and the distribution of tra...
The decline of bat populations across Europe has generated considerable interest and activities for the conservation of this enigmatic group of mammals. However, the factors influencing their distribution and species richness are still poorly understood, particularly on regional scales. We used the presence/absence data of the bat atlas of the Germ...
The ecological reaction of species on environmental factors can differ both, temporally and geographically. Therefore, bioindicator systems must be shown to remain accurate at different places and points of time. Extreme events pose challenges for testing this robustness, which has not yet been explored systematically. The unique opportunity of the...
1. Wood-decaying fungi are crucial for the functioning of forest ecosystems. We tested the hypotheses that on coarse woody debris (CWD), the abundance, diversity and composition of fungi depend more on the amount of available resource than on macro- or microclimate, and that on fine woody debris (FWD) more on the microclimate because of the rapid d...
We determined the climate-sensitive zones along an altitudinal gradient in a low mountain range forest, the Bavarian Forest
National Park in south-eastern Germany, and studied which vascular plant species are likely to respond to climate change.
Plants were recorded on 273 plots along four straight transects. The composition of the plant species an...
The evidence for climate change is increasing, and global warming could lead to the extinction of some species. Here we estimated the extinction risk of six high-montane species of different taxonomic groups (fern, vascular plant, wood-inhabiting fungus, mollusk, saproxylic beetle, and bird) by modeling their occurrence under two global warming sce...
Although the effect of forest management on lichens in temperate forests has been widely examined, little is known about the influence of management-related factors on their biodiversity relative to factors that cannot be altered by management. Here we determined whether forest structure or climate determines lichen diversity in the Bavarian Forest...
Without robust and unbiased systems for monitoring, changes in natural systems will remain enigmatic for policy makers, leaving them without a clear idea of the consequences of any environmental policies they might adopt. Generally, biodiversity-monitoring activities are not integrated or evaluated across any large geographic region. The EuMon proj...
1. Relationships between species richness in higher taxa and large‐scale environmental variables have been widely studied over the past 15 years. Much less is known about how different functional groups (FGs) of species with similar biological and life‐history traits contribute to the overall trends, or how they differ in species‐richness patterns....
Extreme summertime flood events are expected to become more frequent in European rivers due to climate change. In temperate areas, where winter floods are common, extreme floods occurring in summer, a period of high physiological activity, may seriously impact floodplain ecosystems. Here we report on the effects of the 2002 extreme summer flood on...
Environmental change is not likely to act on biodiversity in a random manner, but rather according to species traits that affect assembly processes, thus, having potentially serious consequences on ecological functions. We investigated the effects of anthropogenic land use on functional richness of local hoverfly communities of 24 agricultural land...
Based on a literature review, the different approaches to biological indicator systems in floodplains are summarised. Four general categories of bioindication are defined and proposed here: 1. Classification indicators, 2.1 Environmental indicators, 2.2 Biodiversity indicators, 3. Valuation indicators. Furthermore, existing approaches in floodplain...
This is the first study to relate syrphid life history traits to environmental variables with a multi-trait approach. We aimed to answer two questions: 1. Do syrphid species respond to small scale changes in environmental variables in seasonally flooded grasslands in a Central European floodplain (Elbe)? 2. Can species response to environmental var...
We synthesise the results of the papers in this Special Issue, place them within the context of current trends in floodplain research, and outline promising new avenues that emerge from the contributions. The indication system presented complements existing approaches by focussing on a quantitative indication of environmental parameters. A promisin...
In this article the study design and data sampling of the RIVA project – “Development and Testing of a Robust Indicator System for Ecological Changes in Floodplain Systems” – are described. The project was set up to improve existing approaches to study species environment relationships as a basis for the development of indicator systems and predict...
The relationship of carabid beetle species occurrence patterns and environmental variables characterising the hydrological regime has been studied at the River Elbe in Central Germany. Both flood duration and groundwater depth had major influence on species assemblages as the ordination of study plots mainly followed a gradient along these two vari...
Interactions between syrphid predators and their prey are poorly known. The adaptations of syrphids to aphid defences and the consequences for the evolution of life history traits in these predators especially are mostly unstudied. This is the first of two papers investigating the evolution of prey specialization in aphidophagous hoverflies. The st...
Die Lösung zahlreicher Probleme der Praxis im Fluss- und Auenmanagement erfordert ein ausreichendes Verständnis dieser hochkomplexen, sehr artenreichen und vom Menschen in vielfältiger Weise beeinflussten Lebensräume. Ökologische Untersuchungen verwenden hierfür verschiedene Konzepte zu Umwelt-Organismen-Beziehungen. Je nach Fragestellung kommt es...
Auf Organismen an Wasser wie an Land wirken unzählige Umweltfaktoren ein; diejenigen Faktoren, die entscheidend die Dynamik von Populationen und Lebensgemeinschaften bestimmen, sind von besonderem Interesse für die ökologische Forschung. Auf diese so genannten Schlüsselfaktoren, beispielsweise in Flüssen auf die Strömungsgeschwindigkeiten oder in A...
