Understanding the drivers and consequences of global environmental change is crucial to inform predictions of effects on ecosystems. We used the mammal community of Białowieża Forest, the last lowland near‐primeval forest in temperate Europe, as a sentinel of global change. We analyzed changes in stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope values of hair in 687 specimens from 50 mammal species across seven decades (19...
Introduced alien species can negatively affect native competitors by reducing their populations or eliminating them from ecosystems. However, studies do not always find evidence for anticipated impacts, and changes in native populations can be difficult to estimate. Interactions between the invasive American mink Neovison vison and native European polecat Mustela putorius have been studied in several countries, but the mink’s...
Winter severity limits red fox populations in EurasiaNARA Subscribed
Aim We investigated geographical variation in the density of the red fox in relation to climatic variables, habitat productivity and seasonality to identify those factors that were the best predictors of fox density. Location Published data on red fox abundance were collated from 69 locations over Europe and Asia. Methods Using generalized linear models and the information‐theoretic approach, we analysed the contribution of cl...
