Sudden changes in populations are ubiquitous in ecological systems, especially under
perturbations. The agents of global change may increase the frequency and severity of …

Compared to other animal movements, prospecting by adult individuals for a future breeding
site is commonly overlooked. Prospecting influences the decision of where to breed and has …

Events of non-natural mortality in human-dominated landscapes are especially challenging
for populations of large vertebrates with K strategies. Among birds, vultures are one of the …

Animals explore and prospect space searching for resources and individuals may disperse,
targeting suitable patches to increase fitness. Nevertheless, dispersal is costly because it …

Predators are an important ecological and evolutionary force sha** prey population
dynamics. Ecologists have extensively assessed the lethal effects of invasive predators on …

Rapid progress is being made in understanding how dispersal strategies influence the
spread of species whose ranges are expanding. However, potentially vital dispersal …

Disentangling the influence of demographic parameters and the role of density dependence
on species' population dynamics is a challenge, especially when fractions of the population …

The aim of the present work was to comparatively assess the occurrence and impact of
persistent organic pollutants (POPs) in nine natural and national parks from Spain and …

Wildlife on sandy beaches is often constrained by transformation of natural areas for human
use, and opportunities for acquiring or restoring new habitat are rare. Storms can often force …

Human activities provide wildlife with highly abundant and predictable food subsidies, which
can affect population dynamics and have wide-ranging ecological impacts. A key ecological …
