Anticoagulant Rodenticides Contribute to a Decline in an Urban Carnivore

open access: yesAnimal Conservation, EarlyView.
Anticoagulant rodenticides (ARs) have been shown to negatively affect carnivores globally and are closely tied to human activity and development. We examined drivers of annual survival in bobcats persisting on a residentially developed barrier island over 16 years.
