Hyper abundant mesopredators and bird extinction in an Atlantic forest island
Islands can serve as model systems for understanding how biological invasions affect native species. Here we & examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammal...
