Top Predators as Conservation Tools: Ecological Rationale, Assumptions, and Efficacy
We review the ecological rationale behind the potential compatibility between top predators and biodiversity conservation, and examine their effectiveness as surrogate species. Evidence suggests thatExpand

Individual improvements and selective mortality shape lifelong migratory performance
Billions of organisms, from bacteria to humans, migrate each year and research on their migration biology is expanding rapidly through ever more sophisticated remote sensing technologies. However,Expand

Conflicts between Lesser Kestrel Conservation and European Agricultural Policies as Identif ied by Habitat Use Analyses
European pseudo-steppes have suffered from extensive changes in agricultural practices during the past decades with the disappearance of field margins and fallow systems and the increase of biocideExpand

Long-term effects of lead poisoning on bone mineralization in vultures exposed to ammunition sources.
Long-lived species are particularly susceptible to bioaccumulation of lead in bone tissues. In this paper we gain insights into the sublethal effects of lead contamination on Egyptian vulturesExpand

Foraging habitat selection, land-use changes and population decline in the lesser kestrel Falco naumanni
The selection of foraging habitats by nine radio-tagged adult lesser kestrels (Falco naumanni) breeding in one colony in southern Spain, was studied in 1989 and 1990. Despite individual differencesExpand

Causes and consequences of territory change and breeding dispersal distance in the black kite
Factors affecting individual variation in between-year territory change and dispersal distance were measured in a long-term study of Black Kites (Milvus migrans) living in an area of ∼100000 ha inExpand

Intraguild predation in raptor assemblages: A review
Intraguild predation, the killing of species that use similar resources, has been largely overlooked in raptor investigations. To help fill this gap in knowledge, we conducted a literature review,Expand

Conservation status and limiting factors in the endangered population of Egyptian vulture (Neophron percnopterus) in the Canary Islands
Egyptian vulture populations have decreased sharply in the Western Palearctic; island populations are almost extinct in the Mediterranean and the Macaronesian regions. In the Canary archipelago, theExpand

Ecological, morphological and phylogenetic correlates of interspecific variation in plasma carotenoid concentration in birds
Carotenoids are important as pigments for bright coloration of animals, and as physiologically active compounds with a wide array of health‐related benefits. However, the causes of variation inExpand

Factors Influencing Nest Site Selection, Breeding Density and Breeding Success in the Bearded Vulture (Gypaetus barbatus)
We examined the nest site selection, breeding density and breeding success in the bearded vulture Gypaetus barbatus in relation to physiography, climate, land-use and degree of human disturbance. TheExpand
