Abstract:
... Because of potential conflicts between commercial and conservation interests, one challenge in coastal-area management is how to regulate harvesting practices in coastal areas without adversely affecting the survival of migratory waterbirds. In most Spanish intertidal areas of importance for shorebirds, managers have concentrated only on stock management of the shellfish species. Here, we studied ...
... Comprehensive population parameter data are useful for assessing effective conservation actions. The Fennoscandian arctic fox Alopex lagopus is critically endangered and the population size is estimated at 120 individuals that are fragmented into four isolated populations. Here, we use molecular tracking and visual observations to estimate population size and survival in one of the populations on ...

Abstract:
... Burning has traditionally been used in the southern French Alps to maintain open lands for grazing. In the context of land use abandonment, prescribed burning may be the only realistic practical tool available to oppose encroachment by woody plants in numerous mountainous landscapes. Although only recently developed as a modern tool for wildfire prevention and management of pastoral grasslands, th ...
... Twenty‐five years ago, the snow leopard Uncia uncia, an endangered large cat, was eliminated from what is now Sagarmatha National Park (SNP). Heavy hunting pressure depleted that area of most medium–large mammals, before it became a park. After three decades of protection, the cessation of hunting and the recovery of wild ungulate populations, snow leopards have recently returned (four individuals ...
... The effective conservation of aquatic warbler Acrocephalus paludicola, one of the most threatened western Palaearctic migratory passerines, requires good knowledge of its ecological needs at stopover sites. In particular, identifying its diet, which controls the accumulation of fat reserves during migration, facilitates the selection and management of adequately protected areas. Further key inform ...
... Several studies suggest that species' mortality rates are positively related with local population abundances. Because owls have shown both high road mortality rates and road avoidance behaviours, we hypothesize that road‐kill likelihood is not always directly linked to their occurrence. In this study, we examined the relationship between the likelihood of species occurrence in the vicinity of maj ...

Abstract:
... Ecosystem/habitat restoration has become a major goal of international biodiversity policy. However, restorations are often limited in space or time, and we know little on whether and how restoration and management affect vertebrates. Here we assessed the local and landscape‐scale effects of habitat restoration and management on small‐mammal communities in the Egyek–Pusztakócs marsh system (Hortob ...

Abstract:
... Conservation management typically focuses on protecting wildlife habitat that is linked to important behaviours such as resting, breeding or caring for young. However, development of conservation strategies of social species would benefit from inclusion of social dynamics, particularly for species where social relationships influence fitness measures such as survival and reproduction. We combined ...

Abstract:
... Road mitigation infrastructure for pond‐breeding amphibians aims to provide a safe and sustainable passage for individuals between critical habitat patches. However, relatively little is known about how amphibians interact with mitigation systems because of the challenges of documenting movements at sufficiently large sample sizes. The effect of real or perceived barriers to short‐term movement co ...
