Estimating and forecasting spatial population dynamics of apex predators using transnational genetic monitoring - PNAS

Estimating and forecasting spatial population dynamics of apex predators using transnational genetic monitoring - PNAS | Biodiversité | Scoop.it

The ongoing recovery of terrestrial large carnivores in North America and Europe is accompanied by intense controversy. On the one hand, reestablishment of large carnivores entails a recovery of their most important ecological role, predation. On the other hand, societies are struggling to relearn how to live with apex predators that kill livestock, compete for game species, and occasionally injure or kill people. Those responsible for managing these species and mitigating conflict often lack fundamental information due to a long-standing challenge in ecology: How do we draw robust population-level inferences for elusive animals spread over immense areas? Here we showcase the application of an effective tool for spatially explicit tracking and forecasting of wildlife population dynamics at scales that are relevant to management and conservation.

Regulated hunting re-shapes the life history of brown bears

Regulated hunting re-shapes the life history of brown bears | Biodiversité | Scoop.it
Management of large carnivores is among the most controversial topics in natural resource administration. Regulated hunting is a centrepiece of many carnivore management programmes and, although a number of hunting effects on population dynamics, body-size distributions and life history in other wildlife have been observed, its effects on life history and demography of large carnivores remain poorly documented.
