There are times when birds reproduce at higher rates in places where they are less
abundant, limiting the generally accepted value of bird counts as environmental indicators …

ABSTRACT 1 This review highlights the status of the European wild rabbit Oryctolagus
cuniculus, which is threatened within its native range and yet is a highly successful colonizer …

Summary 1 Territory quality may affect individual fitness and contribute to density‐
dependent reproduction, with repercussions on population regulation. We investigated the …

Summary 1 Electrocution has frequently been suggested as a cause of territory
abandonment and eventual population decline of threatened species, but this has been …

We studied a population of 23–25 Eagle Owl Bubo bubo pairs between 1994 and 2000 in a
1330‐km2 study plot in the central‐eastern Italian Alps. Compared to random sites …

The European Union has adopted the ambitious target of halting the loss of biodiversity by
2010. Several indicators have been proposed to assess progress towards the 2010 target …

Agricultural intensification over the last 60 decades has been linked to decreases in
biodiversity and in the breeding populations of several avian species in farmlands. However …

Attributes of natal habitat often affect early stages of natal dispersal. Thus, environmental
gradients at mountain slopes are expected to result in gradients of dispersal behavior and to …

Little quantitative information on the development and behaviour of chicks and young is
available for many species, despite the crucial importance of such data and the sensitivity of …

Strong numerical and functional responses of owls to voles in cyclic environments are well
known. However, there is insufficient knowledge from the boreonemoral region in particular …
