Effect of uneven tolerance to human disturbance on dominance interactions of top predators. [PDF]
Abstract Anthropogenic activities may alter felid assemblage structure, facilitating the persistence of tolerant species (commonly mesopredators), excluding ecologically demanding ones (top predators) and, consequently, changing coexistence rules. We aimed to determine how human activities influence intraguild relationships among top predators and ...

Extinction debt and functional traits mediate community saturation over large spatiotemporal scales
This study is the first to simultaneously evaluate whether (1) community saturation can require lengthy timespans to be reached and (2) there is a limit to the number of ecological strategies that can coexist. Determining if these ideas are supported is fundamental for better understanding the possible outcomes of species invasions and climate change ...
