How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Since the appearance of Spatial Data Infrastructure several years ago, there has been a tremendous increase in spatial data available on the Internet. This situation raises several research issues, in terms of identifying the content actually accessible via this medium and its impact on governance and local authority management. Our study proposes...
Le projet AMELI propose une méthode participative et multi-échelles pour la prise en compte du bocage et des lisières dans la réalisation de la trame verte et bleue (TVB) de la Région Poitou-Charentes, à partir de l'exemple du bocage bressuirais (Nord Deux-Sèvres). L'enjeu est : - scientifique : identifier et caractériser l'efficacité des continuit...
Radio-tracking of juveniles and genetic studies have previously suggested that mountain ridges may represent barrier to dispersal for the Black grouse. In the present study, we assessed the potential of a more straightforward approach to test the effect of these topological features on Black grouse dispersal. We simply compared correlations between...
The impact of climate change and anthropogenic deforestation on biodiversity is of growing concern worldwide. Disentangling how past anthropogenic and natural factors contributed to current biome distribution is thus a crucial issue to understand their complex interactions on wider time scales and to improve predictions and conservation strategies....
Individuals can increase their conspicuousness to conspecifics while minimizing their probability of detection by predators by choosing the time and location of their display. Conspicuousness arises from the contrast between the light reflected by the colour patches, and the light reflected by the visual background in ambient light used for display...
