Declines in European bird populations are reported for decades but the direct effect of major anthropogenic pressures on such declines remains unquantified. Causal relationships between and population responses difficult to identify as interact at different spatial scales vary among species. Here, we uncover time-series 170 common species, monitored more than 20,000 sites 28 countries, over 37 y, four widespread pressures: agricultural intensification, change forest cover, urbanisation...
Summary Illegal killing/taking of birds is a growing concern across the Mediterranean. However, there are few quantitative data on species and countries involved. We assessed numbers individual each killed/taken illegally in Mediterranean country per year, using diverse range sources incorporating expert knowledge. estimated that 11–36 million individuals year may be region, many them migration. In Cyprus, Egypt, Italy, Lebanon Syria, more than two average year. For such as Blackcap Sylvia...
Abstract Around fifteen thousand fieldworkers annually count breeding birds using standardized protocols in 28 European countries. The observations are collected by country-specific and protocols, validated, summarized finally used for the production of continent-wide annual long-term indices population size changes 170 species. Here, we present database provide a detailed summary methodology fieldwork calculation relative change estimates. We also brief overview how data research,...
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....
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...
Climate warming is driving changes in species distributions and community composition. Many have a so-called climatic debt, that is, shifts range lag behind temperature isoclines. Inside protected areas (PAs), response to climate can be facilitated by greater colonization rates warm-dwelling species, but also mitigated lowering extirpation of cold-dwelling species. An evaluation the relative importance colonization-extirpation processes important inform conservation strategies aim for both...
Animal migrations are unique phenomena involving mass movements of individuals, which pose significant challenges to develop conservation strategies. Migratory seabirds, particularly, face many anthropogenic threats across their distributions, and populations declining worldwide. We provided a thorough isotopic method characterise individual migratory patterns identify main moulting areas two closely-related Puffinus shearwaters breeding in the Mediterranean that produces minimal intrusion...
Greece holds the third larger breeding population of Dalmatian Pelican in world. We present data about establishment and growth, performance conservation status for all six colonies species 40 years. Main features wetlands are described. discuss local, regional global natural anthropogenic factors that may have affected colony growth. After 1982 surveys were carried out with various methods, adapted to particularities each wetland availability resources, targeted estimating number nests...
The greatest loss of biodiversity in the EU has occurred on agricultural land. Common Starling (Sturnus vulgaris) is one many numerous and widespread European farmland breeding bird species showing major population declines linked to intensification. Here we present results based monitoring data collected since 1975 24 countries examine influence changing extent grassland cattle abundance (based earlier studies importance lowland grazed for species), wintering provenance temperature national...
In the present study we investigated diet of Eleonora's falcons in Greece and assessed regional dietary pattern 16 breeding colonies Aegean. Overall 224 nests were visited a total 8067 prey items collected which contained two mollusca classes, seven insect orders, one reptile family, mammalian taxa at least 54 avian species. Cicadas most common insects found pellets (45.1%) followed by flying ants (34.8%) beetles (15.8%) while just 20 species (33.3%) accounted for over 90% identified bird...
Abstract Protected area networks help species respond to climate warming. However, the contribution of a site's environmental and conservation‐relevant characteristics these responses is not well understood. We investigated how composition nonbreeding waterbird communities (97 species) in European Union Natura 2000 (N2K) network (3018 sites) changed response increases temperature over 25 years 26 countries. measured community reshuffling based on abundance time series collected under...
Abstract Sea‐level rise (SLR) is expected to cause major changes coastal wetlands, which are among the world's most vulnerable ecosystems and critical for nonbreeding waterbirds. Because strategies adaptation SLR, such as nature‐based solutions designation of protected areas, can locally reduce negative effects flooding under SLR on it crucial prioritize efforts, especially wetlands international importance biodiversity. We assessed exposure important waterbirds projected along Mediterranean...
Key Biodiversity Areas (KBAs) represent the largest global network of sites critical to persistence biodiversity, which have been identified against standardised quantitative criteria. Sites that hold very high biodiversity value or potential are given specific attention on site‐based conservation targets Kunming‐Montreal Global Framework (GBF), and KBAs already used in indicators for GBF Sustainable Development Goals. However, most species trigger KBA status birds maximise benefits under...
