Journal ArticleDOI
Rapid recovery of a depleted population of Little Bustards Tetrax tetrax following provision of alfalfa through an agri-environment scheme
Vincent Bretagnolle,Alexandre Villers,Leopold Denonfoux,Thomas Cornulier,Pablo Inchausti,Isabelle Badenhausser +5 more
TL;DR: In this paper, the authors assessed the proximate causes of the decline of the Little Bustard in French farming landscapes and quantified the effectiveness of conservation measures that aimed to reverse the decline.
Journal ArticleDOI
Long-term breeding demography and density dependence in an increasing population of Golden Eagles Aquila chrysaetos
Paolo Fasce,Laura Fasce,Alexandre Villers,Alexandre Villers,Franco Bergese,Vincent Bretagnolle +5 more
TL;DR: The results suggest that density dependence, operating across heterogeneous habitats, is currently regulating this population, while the carrying capacity may still be increasing, which may explain the apparent paradox of reduced breeding effort despite increasing total productivity.
Journal ArticleDOI
Migration of wild and captive‐bred Little Bustards Tetrax tetrax: releasing birds from Spain threatens attempts to conserve declining French populations
Alexandre Villers,Alexandre Millon,Alexandre Millon,Frédéric Jiguet,Jean-Michel Lett,Carole Attié,Manuel B. Morales,Vincent Bretagnolle +7 more
TL;DR: Migratory movements and overwintering areas of French migratory populations are identified and birds originating from eggs collected in Spain and reared in western France did not migrate, suggesting a genetic component to migratory behaviour.
Journal ArticleDOI
How individual Montagu's Harriers cope with Moreau's Paradox during the Sahelian winter
Almut E. Schlaich,Raymond H. G. Klaassen,Willem Bouten,Vincent Bretagnolle,Vincent Bretagnolle,Ben J. Koks,Alexandre Villers,Christiaan Both +7 more
TL;DR: Ongoing climate change with less rainfall in the Sahel region paired with increased human pressure on natural and agricultural habitats resulting in degradation and desertification is likely to make this period more demanding, which may negatively impact populations of migratory birds using theSahel.
Journal ArticleDOI
Competitors and predators alter settlement patterns and reproductive success of an intraguild prey
Chiara Morosinotto,Alexandre Villers,Alexandre Villers,Robert L. Thomson,Robert L. Thomson,Rauno Varjonen,Erkki Korpimäki +6 more
TL;DR: Analysis of settlement decisions and reproductive success of Eurasian pygmy owls in the presence of both breeding conspecifics and their competitor and intraguild predator, Tengmalm's owls, under fluctuating abundance of their primary prey suggests short term fitness costs when living close to competitors are higher than those induced by intraspecific competition.
