Reintroductions have been increasingly used for species restoration and it seems that this conservation tool is going to be more used in the future. Nevertheless, there is not a clear consensus about the better procedure for that, consequently a better knowledge of how to optimize this kind of management is needed. Here we examined the dynamics of released long-lived bird populations (lesser ke...
Technological advances for wildlife monitoring have expanded our ability to study behavior and space use of many species. But biotelemetry is limited by size, weight, data memory and battery power of the attached devices, especially in animals with light body masses, such as the majority of bird species. In this study, we describe the combined use of GPS data logger information obtained from fr...
The genetic consequences of small population size and isolation are of central concern in both population and conservation biology. Organisms with a metapopulation structure generally show effective population sizes that are much smaller than the number of mature individuals and this can reduce genetic diversity especially in small sized and isolated subpopulations. Here, we examine the associa...
Farmland habitats host important populations of several threatened bird species. So far, how to reconcile farmland management with the maintenance viable these taxa is a major challenge for conservation biology. Southeastern Italy hosts ca 7000 pairs breeding lesser kestrels Falco naumanni, representing one European strongholds this small colonial raptor concern. We firstly assessed relative im...
The new species Arcoptilia naumanni sp. nov. (Lepidoptera, Pterophoridae) is described and illustrated from males found in Angola. Platyptilia rufamaculata Gielis, 2011, syn. nov. is established as a junior synonym of Arcoptilia pongola Ustjuzhanin & Kovtunovich, 2010.
Spatial segregation of foraging areas among conspecifics breeding in neighbouring colonies has been observed several colonial vertebrates and is assumed to originate from competition information use. Segregation between individuals different parts a same colony comparatively received limited attention, even though it may have strong impacts on structure individual fitness, thus population dynam...
Although successful at recovering endangered populations, conservation actions based on nest provisioning seldom consider how they shape the composition of communities and alter interspecific interactions. Specifically, extent to which dietary overlap within these may affect target species has rarely been assessed. In Southern Europe, sites large-scale nest-site aimed Lesser Kestrels Falco naum...
The impact of bird mortality by collision on windfarms has often been evaluated at the individual level, but rarely population level. Lesser kestrel Falco naumanni is an endangered short-lived migratory raptor, susceptible to with wind turbines. We impacts windfarm turbine collisions demography largest lesser in France. Using data from local monitoring reproduction and surveys, combined capture...
