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...
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,...
Background The trade-off between current and residual reproductive values is central to life history theory, although the possible mechanisms underlying this are largely unknown. 'molt constraint' hypothesis suggests that molt plumage functionality compromised by preceding breeding event, yet candidate mechanism remains insufficiently explored. Methodology/Principal Findings seasonal change in photoperiod was manipulated accelerate rate. This treatment simulates case of naturally...
Abstract Natural sounds, and bird song in particular, play a key role building maintaining our connection with nature, but widespread declines populations mean that the acoustic properties of natural soundscapes may be changing. Using data-driven reconstructions lieu historical recordings, here we quantify changes soundscape characteristics at more than 200,000 sites across North America Europe. We integrate citizen science monitoring data recordings individual species to reveal pervasive...
Female-biased sex ratio is a common phenomenon in parasites; however, the cause and consequence of skewed less well known. Here, we studied difference ratio, possible mechanism responsible for development unbalanced proportion sexes its consequences on sexual size dimorphism, between 3 louse species parasitizing house sparrow Passer domesticus. Philopterus fringillae was more prevalent than Sturnidoecus refractariolus Brueelia cyclothorax. As expected, most species, which probably least...
Social groups often consist of diverse phenotypes, including personality types, and this diversity is known to affect the functioning group as a whole. selection theory proposes that composition (i.e. social environment) also influences performance individual members. However, effect behavioural on members remains largely unexplored, it still contentious whether individuals benefit more in environment with homogeneous or composition. We experimentally formed house sparrows Passer domesticus...

Because it is impossible to comprehensively characterize biodiversity at all levels of organization, conservation prioritization efforts need rely on surrogates. As species distribution maps relished groups as well high-resolution remotely sensed data increasingly become available, both types surrogates are commonly used. A good surrogate should represent much possible, but often remains unclear what extent this the case. Here, we aimed address question by assessing how bird and habitat...
