Emergent optimal foraging theory-based models for individual variation go beyond the population level and predict how its individuals would respond to disturbances that produce changes in resource availability. 2. Evaluating variations in resource u...

Aim To explore the influence of an emerging infectious disease (EID) affecting a prey species on the spatial patterns and temporal shifts in the diet of a predator over a large geographical scale. We reviewed studies on the diet of Bonelli’s eagles (Hieraaetus fasciatus) in order to determine the repercussions of the reduction in the density of its...

Between 1995 and 2005, 827 contacts were obtained with bats in 118 localities in the Camargue using various methods. Altogether, 21 species were found during the study (a 22nd, Nyctalus lasiopterus, was mentioned outside). Six species are common (Eptesicus serotinus, Pipistrellus pipistrellus, P. pygmaeus, P. kuhlii, P. nathusii, and Tadarida tenio...

The common genet (Genetta genetta) is a small carnivoran that was probably introduced from Maghreb into south‐western Europe. We reassessed its easternmost European distribution from 110—mostly new—data collected in south‐eastern France and Italy, and tested for potential habitat selection, to finally re‐evaluate the role of the Rhône as a geograph...

Capsule: In this region the diet is mainly cold-blooded prey, mostly insects such as beetles. Aims: To describe the diet of this newly separated, poorly documented and endangered species. Method: Diet was inferred from pellet analysis, collected during a single breeding and winter period in the steppe of the Crau. Results: A total of 5409 prey were...

The diet of young Golden Eagles Aquila chrysaetos in Corsica (Western Mediterranean) has been studied by identifying remains and pellets collected at nests after fledging from 1991 to 1996. Ten mammalian species, 17 birds and two reptiles have been identified, of which snakes, Bovidae (mostly Feral Goat Capra hircus), Wild Boar Sus scrofa and Corvi...

We studied the diet of two pairs of Eurasian Eagle Owl Bubo bubo in Castellar and Gorbio (Alpes-Maritimes), according to prey remains collected in the nests. 411 preys, distributed in 51 species, were identified. In Castellar the Eagle Owls' diet was based mainly on Brown Rat Rattus norvegicus (37%), Black Rat Rattus rattus (24%) and Edible Dormous...

Only 2 categories of prey are of major importance in this area: rabbit Oryctolagus cuniculus on the one hand, and edible dormouse Glis glis and rats Rattus spp. on the other. These 2 kinds of prey are complementary. Rabbit ("optimum' prey) is predominant in the diet W of the Bouches-du-Rhone. -from English summary
