Spatially varying density dependence drives a shifting mosaic of survival in a recovering apex predator (Canis lupus)
October 27, 2020
Understanding landscape patterns in mortality risk is crucial for promoting recovery of threatened and endangered species. Humans affect mortality risk in large carnivores such as wolves (Canis lupus), but spatiotemporally varying density dependence can significantly influence the landscape of survival. … read more
