Summary 1. Species distribution models are increasingly used to address questions in conservation biology, ecology and evolution. The most effective species require data on both presence the available environmental conditions (known as background or pseudo‐absence data) area. However, there is still no consensus how where sample these pseudo‐absences many. 2. In this study, we conducted a comprehensive comparative analysis based simple simulated distributions propose guidelines how, many...
In this paper, we tested whether the spatial distribution of a given species in more or less fragmented and disturbed landscapes depends on habitat specialization. We studied 891 replicates from French Breeding Bird Survey (FBBS) monitored at least two years during 2001–2005, independent landscape databases measuring respectively fragmentation recent disturbance each FBBS replicate. used continuous specialization index for 105 most common bird by FBBS. further modelled variation abundance...
Range shifts of many species are now documented as a response to global warming. But whether these observed changes occurring fast enough remains uncertain and hardly quantifiable. Here, we developed simple framework measure change in community composition climate This is based on temperature index (CTI) that directly reflects, for given assemblage, the balance between low- high-temperature dwelling species. Using data from French breeding bird survey, first found strong increase CTI over...
ABSTRACT Aim Worldwide, functional homogenization is now considered to be one of the most prominent forms biotic impoverishment induced by current global changes. Yet this process has hardly been quantified on a large scale through simple indices, and connection between landscape disturbance established. Here we test whether changes in land use fragmentation are associated with bird communities at national scale. Location France. Methods We estimated community as average specialization...
Abstract Few studies have examined how life history traits and the climate envelope influence ability of species to respond change habitat degradation. In this study, we test whether 18 species‐specific variables, related envelope, ecological history, could predict recent population trends (over 17 years) 71 common breeding bird in France. Habitat specialists were declining at a much higher rate than generalists, sign that quality is decreasing globally. The lower thermal maximum...
The increase in species richness from the poles to tropics, referred as latitudinal diversity gradient, is one of most ubiquitous biodiversity patterns natural world. Although understanding how rates speciation and extinction vary with latitude central explaining this pattern, such analyses have been impeded by difficulty estimating diversification associated specific geographic locations. Here, we use a powerful phylogenetic approach nearly complete phylogeny mammals estimate speciation,...
Abstract: We studied the community richness and dynamics of birds in landscapes recently affected by urbanization to test prediction that biotic communities living degraded are increasingly composed generalist species. analyzed bird 657 plots monitored French Breeding Bird Survey from 2001 2005, accounting for probability species detection spatial autocorrelation. used an independent land‐cover program assess intensity each FBBS plot, 1992 2002. found induced homogenization populations...
Rapid climatic change poses a threat to global biodiversity. There is extensive evidence that recent has affected animal and plant populations, but no indicators exist summarise impacts over many species large areas. We use data on long-term population trends of European birds develop such an indicator. find significant relationship between interspecific variation in trend the potential range extent late 20(th) 21(st) centuries, forecasted by envelope models. Our indicator measures...
Birds populations allied in abundance Changes climate can cause of species to decline, increase, or remain steady. Stephens et al. looked across common birds Europe and the United States. Despite many differences between two regions, expectations about how a might respond change did predict actual responses. Species predicted benefit from increasing temperatures, their associated effects, tended whereas those be negatively affected declined. Thus, even widely varying ecological conditions...
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 Many species have already shifted their distributions in response to recent climate change. Here, we aimed at predicting the future breeding of European birds under climate, land‐use, and dispersal scenarios. We predicted current 409 within an ensemble forecast framework using seven distribution models ( SDM s), five scenarios three emission land‐use then compared results from s climate‐only variables, habitat‐only variables or both habitat variables. In order account for a species’...
Abstract Aim The impact of multiple stressors on biodiversity is one the most pressing questions in ecology and conservation. Here we critically assess how often efficiently two main drivers global change have been simultaneously integrated into research, with aim providing practical solutions for better integration future. We focus climate (CC) land‐use (LUC) when studying changes species distributions. Location Global. Methods analysed peer‐reviewed literature effects CC LUC observed...
Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens habitat integrity and connectivity for conservation human health; global network of sentinels change.
Abstract Climate change, habitat degradation, and direct exploitation are thought to threaten biodiversity. But what makes some species more sensitive global change than others? Approaches this question have relied on comparing the fate of contrasting groups species. However, if ecological parameter affects faced with response should vary smoothly along gradient. Thus, grouping into few, often two, discrete classes weakens approach. Using data from common breeding bird survey in France – a...
We explore population trends of widespread and common woodland birds using data from an extensive European network ornithologists for the period 1980–2003. show considerable differences exist in species according to broad habitat they occupy degree which specialize use. On average, forest are shallow decline at a scale; declined by 13%, specialists 18%, 1980 2003. In comparison, populations farmland have moderately, falling on average 28% These patterns contrast with that shown generalist...
Aim To test how far can macroecological hypotheses relating diversity to environmental factors be extrapolated functional and phylogenetic diversities, i.e. the extent which traits evolutionary backgrounds vary among species in a community or region. We use spatial partitioning of where regional γ-diversity is calculated by aggregating information on local communities, α-diversity corresponds one locality, turnover β-diversity average between localities Location France. Methods used Rao...
Climate suitability models are used to make projections of species’ potential future distribution under climate change. When studying the species richness with such modeling methods, extent study range is particular importance, especially when full occurrence not considered for some species, often because geographical or political limits. Here we examine biases induced by use range‐restricted data on predicted changes in and extinction rates, at area margins. We compared suitable space 179...
Citizen science, defined as participation of the general public in scientific research, could significantly help scientists to address biodiversity issues, through (i) monitoring state biodiversity, (ii) framing indicators which synthesise and communicate information on (iii) building scenarios evaluate plausible consequences different policies. A key asset citizen science is that participating citizens disseminate they gain, thereby increasing profile issues being researched. We review...
Beyond the effects of temperature increase on local population trends and species distribution shifts, how populations a given are affected by climate change along range is still unclear. We tested whether responses to related locations within thermal range. compared average 20 year growth rates 62 terrestrial breeding birds in three European countries latitudinal gradient ranges. After controlling for factors already reported affect bird (habitat specialization, migration distance body...
