Dispersal costs can be classified into energetic, time, risk and opportunity costs and may be
levied directly or deferred during departure, transfer and settlement. They may equally be …

Birds of prey have been, in comparison to other avian groups, an uncommon study model,
mainly due to the limitations imposed by their conservative life strategy (low population …

Density‐dependent dispersal can be caused by various mechanisms, from competition
inducing individuals to emigrate (positive density‐dependence) to social crowding effects …

The nominal subspecies of the Black Kite is a summer resident in Europe and Asia that
winters mostly in western Africa, although numbers of birds wintering in the Mediterranean …

The effects of search costs on habitat selection by dispersers are largely unknown. We
explore how habitat selection behavior is affected by the risk of mortality en route and by …

The main objective of many conservation programs is to increase population size by
improving a species' survival and reproduction. However, density dependence of …

Abstract The European rabbit (Oryctolagus cuniculus) is a key prey species in
Mediterranean ecosystems and is ecologically plastic. However, ecological responses of …

We compared movement patterns and rhythms of activity of a top predator, the Iberian lynx
Lynx pardinus, a mesopredator, the red fox Vulpes vulpes, and their shared principal prey …

Extinctions are often the result of multiple factors that are difficult to disentangle and so
methods for identifying simple and combined types of extinctions are valuable for both basic …

Summary 1 Many studies investigating fitness correlates of dispersal in vertebrates report
dispersers to have lower fitness than philopatric individuals. However, if dispersers are more …
