Sources of variation in mortality of the Bearded Vulture Gypaetus barbatus in Europe
We analyse the causes of mortality for the Bearded Vulture in Europe. Shooting (31%), intentional poisoning (26%), collision (18%) and unintentional poisoning (12%) were the most important causes of mortality. No differences were found between sexes or age classes (nonadults and adults) for any of the causes of death. When the four main categories of mortality were grouped in periods of 3 years...
متن کاملPhylogeography, genetic structure and diversity in the endangered bearded vulture (Gypaetus barbatus, L) as revealed by mitochondrial DNA.
Bearded vulture populations in the Western Palearctic have experienced a severe decline during the last two centuries that has led to the near extinction of the species in Europe. In this study we analyse the sequence variation at the mitochondrial control region throughout the species range to infer its recent evolutionary history and to evaluate the current genetic status of the species. This...
متن کاملDietary habits in the endangered Bearded Vulture Gypaetus barbatus from Upper Pleistocene to modern times in Spain: a paleobiological conservation perspective
Although most Old World vulture species are declining or threatened in Asia and Africa, in Europe healthy vulture populations still exist. However, recent application of sanitary legislation that has greatly reduced the availability of animal carcasses is now a concern for conservationists. Until now, no studies have been undertaken to determine long-term dietary shifts in these species in Euro...
متن کاملSpatial and temporal movements in Pyrenean bearded vultures (Gypaetus barbatus): Integrating movement ecology into conservation practice
Understanding the movement of threatened species is important if we are to optimize management and conservation actions. Here, we describe the age and sex specific spatial and temporal ranging patterns of 19 bearded vultures Gypaetus barbatus tracked with GPS technology. Our findings suggest that spatial asymmetries are a consequence of breeding status and age-classes. Territorial individuals e...
متن کاملHematology and blood chemistry reference values and age-related changes in wild Bearded Vultures (Gypaetus barbatus).
Normal hematologic and blood chemistry values for clinical use and age-related changes are reported as reference values for the endangered Bearded Vulture (Gypaetus barbatus). Blood samples were obtained from 21 nestlings and 26 free-living subadults and adults. No significant differences were found between subadults and adults or between sexes for any of the studied parameters. Reference range...
