The purpose of this study was to document the prevalence and severity of osteoarthritis and how it varied with age and among sexes in a wild population of moose. We also assessed whether the prevalence and severity of osteoarthritis was … read more

Species distribution models can facilitate conservation planning and action but presume species-environment relationships are stable, which is not the case for invasive or recolonizing species only partially occupying their potential distributions. This complicates our understanding of colonization and recolonization processes … read more

Habitat selection studies facilitate assessing and predicting species distributions and habitat connectivity, but habitat selection can vary temporally and among individuals, which is often ignored. We used GPS telemetry data from 96Gray wolves (Canis lupus) in the western Great Lakes … read more

Large terrestrial carnivores are now widely recognized as essential components of ecosystems. However, the management of large carnivores varies greatly at national and international scales, and some management decision processes do not seem to be informed by scientific evidence. We … read more

Conserving endangered species sometimes involves killing their predators. In the case of Nearctic wolves (Canis lupus), rarely are lethal control measures examined for ancillary effects on predator behaviour or community responses in a before-after design. We examined wolf relative abundance … read more
