Climate change is predicted to cause changes in species distributions and several studies report margin range shifts some species. However, the reported rarely concern a species' entire distribution are not always linked climate change. Here, we demonstrate strong north-eastwards centres of gravity wintering three common waterbird along North-West Europe flyway during past decades. These correlate with an increase 3.8 °C early winter temperature north-eastern part areas, where bird abundance...

Abstract: As countries worldwide become increasingly interested in conserving biodiversity, the profile of national threatened species lists expands and these more influential determining conservation priorities. The World Conservation Union (IUCN) Categories Criteria for evaluating extinction risk, originally intended use at global level, are being used level. To facilitate this process, IUCN recently published guidelines application criteria subglobal levels. We evaluated guidelines,...

Abstract Climate change has been associated with both latitudinal and elevational shifts in species’ ranges. The extent, however, to which climate driven recent range alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years explore dynamics, considering effects climate, land cover, environmental variables, traits on probability local colonisation extinction. On average, shifted their ranges by 2.4 km/year....

Species respond dynamically to climate change and exhibit time lags. Consequently, species may not occupy their full climatic niche during range shifting. Here, we assessed tracking recent shifts of European United States (US) birds. Using data from two bird atlases the North American Breeding Bird Survey between 1980s 2010s, analysed overlap based on kernel density estimation. Phylogenetic multiple regression was used assess effect morphological, ecological biogeographic traits metrics....

Abstract Aim Species are responding to climate change by changing their distributions, creating debate about the effectiveness of existing networks protected areas. As a contribution this debate, we assess whether regional winter abundances and distribution Smew Mergellus albellus , migratory waterbird species listed on Annex I ( EU Birds Directive) that overwinters exclusively in European wetlands, changed during 1990–2011, role global warming driving distributional changes network Special...

Abstract Wetland bird species have been declining in population size worldwide as climate warming and land-use change affect their suitable habitats. We used distribution models (SDMs) to predict changes range dynamics for 64 non-passerine wetland birds breeding Europe, including size, position of centroid, margins. fitted the SDMs with data collected first European Breeding Bird Atlas distributional over a century (the 1970s–2070s). The predicted annual were then compared observed centroid...

Abstract: National red lists of threatened animal and plant species prepared according to the criteria World Conservation Union (IUCN) adequately reflect extinction risk within a country but cannot be used directly set conservation priorities. In particular, significance national populations for as whole is not taken into account. We present procedure that can assess responsibility based on red‐list status species, international importance population, species' “historical rarity” status....

Abstract Aim Many species are showing distribution shifts in response to environmental change. We explored (a) the effects of inter‐annual variation winter weather conditions on non‐breeding distributional abundance waterbirds exploiting different habitats (deep‐water, shallow water, farmland) and (b) long‐term shift population centroid these investigate its link changes conditions.

Species’ range shifts and local extinctions caused by climate change lead to community composition changes. At large spatial scales, ecological barriers, such as biome boundaries, coastlines, elevation, can influence a community's ability shift in response change. Yet, barriers are rarely considered studies, potentially hindering predictions of biodiversity shifts. We used data from two consecutive European breeding bird atlases calculate the geographic distance direction between communities...

Migratory waterbirds require an effectively conserved cohesive network of wetland areas throughout their range and life-cycle. Under rapid climate change, protected area (PA) networks need to be able accommodate climate-driven shifts in wildlife if they are continue effective the future. Thus, we investigated geographical variation relationship between local temperature anomaly abundance 61 waterbird species during wintering season across Europe North Africa 1990–2015. We also compared...

We analysed annual changes in abundance of EurasianWigeon (Anas penelope) derived frommid-winter InternationalWaterbird Census data throughout its northwest European flyway since 1988 using log-linear Poisson regressionmodelling. Increases the north and east wintering range (Norway, Sweden, Denmark, Germany, Switzerland), stable numbers central (Belgium,Netherlands,UKand France) declining west south (Spain Ireland) suggest a shift distribution consistent with milder winters range. However,...

Summary In Europe, population estimates of breeding birds are produced nationally and periodically compiled at EU or pan-European scales. Until now, no other source was available to explore the robustness these estimates. this study, we compared sizes reported in latest edition European Red List Birds (ERLoB) with those using data from second Breeding Bird Atlas (EBBA2) assess their consistency determine parameters behind variability that deserve further attention future. general, derived...
