Population sizes of many birds are declining alarmingly and methods for estimating fluctuations in species' abundances at a large spatial scale are needed. The possibility to derive indicators from the tendency of specific species to co-occur with others has been overlooked. Here, we tested whether the abundance of resident titmice can act as a gen...
Article
Full-text available
The impact of global change on biodiversity is commonly assessed in terms of changes in species distributions, community richness and community composition. Whether and how much associations between species are also changing is much less documented. In this study, we quantify changes in large-scale patterns of species associations in bird communiti...

Protected areas are the flagship management tools to secure biodiversity from anthropo-genic impacts. However, the extent to which adjacent areas with distinct protection levels host different species numbers and compositions remains uncertain. Here, using reef fishes, European alpine plants, and North American birds, we show that the composition o...
Article
Global changes alter the dynamics of biodiversity, and are forecasted to continue or worsen in the decades to come. Modelling approaches used to anticipate these impacts are mainly based on the equivalence between spatial and temporal response to environmental forcings, generally called space‐for‐time substitution. However, several processes are kn...

Full-text available
The global scientific community has become increasingly diverse over recent decades, but is this ongoing development also reflected among top‐publishing authors and potential scientific leaders? We surveyed 13 leading journals in ecology, evolution, and conservation to investigate the diversity of the 100 top‐publishing authors in each journal betw...
Article
Full-text available
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non‐breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate‐driven community shifts has not been thoroughly investigated at large spatial scales. 2. We c...
Preprint
Full-text available
Aim The impact of global change on biodiversity is commonly assessed in terms of changes in species distributions, species richness and species composition across communities. Whether and how much interactions between species are also changing is much less documented and mostly limited to local studies of ecological networks. Moreover, we largely i...
Article
Aim. This study investigates whether, and how the composition of riparian bird communities has been affected by climate warming and habitat change. Although these two forces act separately, their respective contributions are rarely examined. Moreover, while the response of a given community may be a function of latitude and altitude, most studies h...
Article
Adopting a multifaceted approach of biodiversity is believed to capture different aspects of the ecosystem functioning and it is thus advised for conservation prioritisation, especially for anthropogenic ecosystems but this key topic has never been conducted for the Mediterranean tree assemblages, despite their ecological importance. We explored ho...
Article
Full-text available
Temporal dynamics in ecological variables are usually assessed using linear trends or smoothing methods. Those trends qualitatively summarise the increase or decrease in the variable of interest over a given time period. Yet, linear trends do not capture changes in the direction or in the rate of change of indices such as population trajectories, t...
Article
Rural landscapes of western Europe have considerably changed in the last decades under the combined pressure of climate and land use changes, leading to a dramatic decline of farmland biodiversity, including common farmland birds. The respective roles of climate and land use and cover changes in driving bird population trends are primarily assessed...
Article
Full-text available
Latitudinal and altitudinal range shifts in response to climate change have been reported for numerous animal species, especially those with high dispersal capacities. In plants, the impact of climate change on species distribution or community composition has been documented mainly over long periods (decades) and in specific habitats, often forest...

Article
Community Weighted Means (CWM) are valuable tools describing community composition with respect to one given trait. They have been widely used as indicators in global change studies to measure biodiversity responses to environmental perturbations. However, how individual species contribute to such community indicators has hardly been investigated....
Data
Results of the meta-community pattern analysis on the first two axis of the Redundancy Analysis (RDA). (see Presley, Higgins and Willig, 2010 and Leibold and Mikkelson, 2002) The table present the value of the different indices, computed with the « meta-community function » in Matlab (see Leibold and Mikkelson, 2002): Abs = the number of embedded a...

Article
Full-text available
The relative contribution of ecological processes in shaping metacommunity dynamics in heavily managed landscapes is still unclear. Here we used two complementary approaches to disentangle the role of environment and spatial effect in farmland bird community assembly in an intensive agro-ecosystem. We hypothesized that the interaction between habit...
Data
Correlation between the RDA axis (first two axis) and the environmental variables at each environmental grain. (DOCX)
Data
Variation partitioning: comparison between two spatial models: Principal Coordinates of Neighbor Matrices (PCNM) and Trend Surface Analysis (TSA). Results are presented without the temporal component. In this analysis, all sessions and years have been pooled together. Because land use varied between years, both the mean (M) and the coefficient of v...
Data
Database. The database contains all the data from the point counts and GIS data. This includes the ID of the point (“IdPoint”), the year and the session (2 sessions per year from 2009 to 2013). The abundance of each species is reported on the table. The first column (“Gradient_HedgerowsForest200m”) corresponds to the gradient of wooded components u...
Data
Species list (per class) and results of the redundancy analysis (RDA). We observe that the three species classes are ordinated along the first axis of the RDA, which is strongly correlated with a gradient of wooded component (see also S4 Appendix). This first axis explains 17.65% of the total variation, while the second axis explains 9.23%. (DOCX)
Data
Analysis of species co-occurrence by correspondence analysis. Species are distributed along a tree cover gradient (strong correlation with the first axis of the correspondence analysis). A dendrogram can be built by transforming the ordination value along this axis into the Euclidean distance. Three species classes can be distinguished using the de...
Data
Variation partitioning for each class of landscapes (open, intermediate and wooded) (4a) and each class of species (open-land, intermediate and woodland species) (4b). The curves represent the variation explained by each variable: environmental (green), geographical (blue), temporal (red) and all interactions in relation to the part of explained va...
Thesis
L’état et le devenir de la diversité biologique préoccupent la science et la politique depuis près d’un demi-siècle. Dans ce travail, nous questionnons le modèle linéaire en vigueur qui suppose que la recherche scientifique décrit une réalité objective sur laquelle la politique peut s’appuyer pour formuler des décisions éclairées sur la « crise de...
Article
The articulation between knowledge and actions in three environmental devices: conservation, impact assessment, and restoration. In the actions on nature, the ecological knowledge is decisive and source of legitimisation. The reasons why certain kinds of knowledge are promoted or avoided are nevertheless rarely made explicit. This article aims to c...
Article
New agendas for conservation are regularly proposed based on the ground that existing strategies are overly pessimistic, restricted to biodiversity hotspots, and inappropriate to halt biodiversity loss. However, little empirical evidence supports such claims. Here we review the 12971 papers published in the leading conservation journals during the...
Article
How can the title of a paper affect its subsequent number of citations? We compared the citation rate of 5941 papers published in the journal Biological Conservation from 1968 to 2012 in relation to: paper length; title length; number of authors; paper age; presence of punctuation (colons, commas or question marks); geographic and taxonomic breadth...
Article
Aim This study analyses the places and the scales at which the latitudinal diversity gradient (LDG) for vertebrate species holds or, conversely, fails. Although much empirical support for the LDG at a global scale exists, several marked departures have also been previously reported for some regions, scales and organisms. Here, we aim to test the ge...
Article
Biodiversity offsetting relies on scientific hypotheses that are barely investigated. The aim of this paper is first to explore under what conditions it is possible to envisage biodiversity compensation from the perspectives of ecological science and planning policies. Two fundamental assumptions are scrutinized: the issue of substitution of a give...
Article
Full-text available
In the current context of global change and a biodiversity crisis, there are increasing demands for greater predictive power in ecology, in both the scientific literature and at the science–policy interface. The implicit assumption is that this will increase knowledge and, in turn lead to better decision-making. However, the justification for this...
Article
Full-text available
Understanding the relative contribution of different species interactions in shaping community assembly has been a pivotal aim in community ecology. Biotic interactions are acknowledged to be important at local scales, although their signal is assumed to weaken over longer distances. We examine the relationship between positive, neutral and negativ...
Article
Full-text available
This paper is a critical assessment of the epistemological impact of the systematic quantification of nature with the accumulation of big datasets on the practice and orientation of ecological science. We examine the contents of big databases and argue that it is not just accumulated information; records are translated into digital data in a proces...
Article
Full-text available
Many species have suffered large population declines due to the anthropogenic influence on ecosystems. Understanding historical population trends is essential for informing best efforts to preserve species. We propose a new method to reconstruct the past structure of a regional species pool, based on historical naturalist literature. Qualitative in...

Change in Community Specialization Index of common breeding birds in the Camargue over time. Only species with an abundance coded by 2 (“common”) were included in this analysis. (TIF)
Data
Breeding bird species in the Camargue with annotated abundance over time. Abundance is given by a species commonness index coded by “0” if breeding was unknown at that time period, “1” if the species was rare, and “2” if the species was common. (XLS)
Data
Main habitat used by breeding birds in the Camargue. Our classification is based on the European Bird Census Council (EBCC) classification for the Mediterranean region with an additional category (wetland) and additional species not assessed yet by the EBCC experts. (XLSX)
Article
Biological Conservation recently rejected a paper because we regarded the killing of thousands of vertebrates in a protected area as unnecessary and inappropriate. The authors had the required approvals from the conservation authorities for this work and argued that alternative non-harmful methods, such as camera-traps and baited video, or capture-...
Article
The spatial tracking of climatic shifts is frequently reported as a biodiversity response to climatic change. However, species' range shifts are often idiosyncratic and inconsistent with climatic shift predictions. At the community scale, this discrepancy can be measured by comparing the spatial shift in the relative composition of cold- vs warm-ad...
Article
Full-text available
Human activities may generate geometrical landscape (i.e. composed of rectilinear and repetitive landscape units) structures that can significantly influence the spatial distribution of birds. While bird distribution in various landscape types has been extensively studied, the role played by landscape configuration and composition in different face...
Article
Climate change is known to drive both the reshuffling of whole assemblages and range shifts of individual species. Less is known about how local colonizations and extinctions of individual species contribute to changes at the community level. Our aim was to estimate the contribution of individual species to a change in community composition attribu...

Article
Protected areas (PAs) are the mainstay of our conservation strategies. While they may succeed in locally preventing species and habitat degradation due to human activities, their ability to mitigate the impacts of climate change on biodiversity is still debated. We assessed whether community and species responses to climate change were related to P...
Article
In the era of sustainable development it is hard to find anyone who will argue in favour of recognizing the importance of conflict. Although often incompatible, we strive to align conservation goals with development imperatives, and finding the best compromise is a leitmotiv in conservation science. But it should not be forgotten that compromises c...

Ecological specialization provides information about adaptations of species to their environment. However, identification of traits representing the relevant dimensions of ecological space remains challenging. Here we endeavoured to explain how complex habitat specializations relate to various ecological traits of European birds. We employed phylog...

Full-text available
The local spatial congruence between climate changes and community changes has rarely been studied over large areas. We proposed one of the first comprehensive frameworks tracking local changes in community composition related to climate changes. First, we investigated whether and how 12 years of changes in the local composition of bird communities...
Article
Aim We disentangle three facets of species commonness (local abundance, geographical range size, degree of habitat generalization) to identify how species segregate along these axes and how each of these facets determines the relative functional originality of each species (i.e. the mean trait distance of a species with others). At the community le...

Full-text available
Riparian landscapes of large breaded rivers experience noticeable changes at the decade scale, and that should be considered to address management or/and conservation issues. Here, we analyzed a long term bird monitoring program distributed over 3 french rivers (Loire, Allier and Doubs) to assess these changes through bird community description ove...

Poster
Full-text available
Understanding the mechanisms that generate biodiversity patterns require studies at multiple spatial and temporal scales. Communities can be shaped by different processes, not mutually exclusive: demographic stochasticity, dispersal, environmental filtering or biotic interactions. But these processes are strongly scale-dependent and can vary depend...

Species and community specialization have become popular indicators to track the spatial and temporal changes of species and community dynamics during current global changes. However, measuring specialization requires detailed and quantitative descriptions of habitat requirements or resource use, which are difficult to obtain for many species. Here...

1.The α, β, γ diversity decomposition methodology is commonly used to investigate changes in diversity over space or time but rarely conjointly. However, with the ever-increasing availability of large-scale biodiversity monitoring data, there is a need for a sound methodology capable of simultaneously accounting for spatial and temporal changes in...
