ecological communities. Reduced apex predator occupancy or activity can release …

The decline of predators in a variety of ecosystems has transformed community structure
through mesopredator release and trophic cascades. Elasmobranch fishes, one of the …

Corridor Ecology presents guidelines that combine conservation science and practical
experience for maintaining, enhancing, and creating connectivity between natural areas with …

Carnivore guilds play a vital role in ecological communities by cascading trophic effects,
