Conserving cougars in a rural landscape: habitat requirements and local tolerance in west-central AlbertaDownload
Maintaining large carnivores in human-dominated landscapes poses a significant conservation challenge. Extirpation is common because of habitat loss or direct persecution. I studied cougar habitat selection and human perception of cougars in west-central Alberta to better understand...
Two reclaimed coal mines in west-central Alberta host a complex assemblage of large-bodied predator and prey populations, including cougars (Puma concolor), bighorn sheep (Ovis canadensis), elk (Cervus elaphus), and mule deer (Odocoileus hemionus). The presence of ungulate and predator...
Predation by cougars (Puma concolor) variously can structure ecosystems and preserve biodiversity, engender conflict where livestock and pets are killed, and even drive prey populations to extinction. Effective management requires a firm grasp of the ecological drivers of predation, but these...
Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...
Spatial ecology of cougars (Puma concolor) in the Cypress Hills: Implications for human-cougar interactions and range expansionDownload
Cougar (Puma concolor) range is expanding eastward in North America. Understanding how range expansion is occurring in a human-dominated landscape is needed to manage the social and ecological implications of a returning large carnivore. To address this, I used GPS-radio collars and...
Although typically referred to as a generalist species, individual prey specialization has been documented in cougars (Puma concolor). This behaviour has the potential to limit and regulate ungulate dynamics, particularly in cases where ungulates exist in small or isolated populations. Cougars...
