Electrocution threatens the viability of populations of the endangered Bonelli's eagle (Aquila fasciata) in Southern Europe

摘要: Abstract Electrocution on power lines negatively affects a wide range of groups birds. Nevertheless, the overall demographic consequences electrocution are still poorly understood. Typically, little data is available for endangered species and so approaches aimed at guiding conservation measures that bear in mind this uncertainty urgently required. In present study, we develop procedure based population modeling useful both obtaining unbiased estimates mortality caused by estimating mitigation effort required to restore threatened populations — even if regarding parameter exists. We used as case study Bonelli's eagle ( Aquila fasciata ) NE Iberian Peninsula. Firstly, multievent models estimate while accounting imperfect detection state assignment. The fraction α was not directly estimable from developed method addition basic monitoring information. Accordingly, estimated 0.26 0.62 for, respectively, territorial non-territorial individuals period 2008–2014. Secondly, applied viability analysis gauge would be mitigate guarantee self-sustainability. Our results highlight fact low levels can drive local extinction. Overall, our establishes framework effects provides managers with information needed human-induced populations.
