Mapping potential habitat for naturally recolonizing cougars (Puma concolor) in Missouri, USA
Global Ecology and ConservationCougars (Puma concolor) have been increasingly documented in the Midwestern United States in the past few decades following historical extirpation, including in Missouri (USA), where verified sightings occur regularly. To map potential habitat and inform

Stepping stones to extirpation: Puma patch occupancy thresholds in an urban‐wildland matrix
Ecology and Evolution, 2023 Habitat loss and fragmentation are the leading causes of species range contraction and extirpation, worldwide. Factors that predict sensitivity to fragmentation include high trophic level, large body size, and extensive spatial requirements.

Research to regulation: Cougar social behavior as a guide for management
Wildlife Society Bulletin, 2013 Cougar (Puma concolor) populations are a challenge to estimate because of low densities and the difficulty marking and monitoring individuals. As a result, their management is often based on imperfect data.

Use of radio‐linked VHF technology to monitor neonate carnivores
Wildlife Society Bulletin, 2023 Fine‐scale monitoring of neonate mammals can provide important data about survival rates and cause‐specific mortality. However, the VHF transmitters and collars frequently used to monitor neonate mammals necessitate logistically intensive field efforts ...

Less invasive monitoring of cougars in Colorado's front range
Wildlife Society Bulletin, 2019 From 2014 to 2016, in the Front Range of Colorado, USA, we assessed noninvasive approaches to sampling cougar (Puma concolor) populations in an attempt to provide a new method that would be less field intensive, less expensive, and could be applied over ...

Do GPS clusters really work? carnivore diet from scat analysis and GPS telemetry methods
Wildlife Society Bulletin, 2011 Global Positioning System (GPS) data collected using radiocollars have allowed researchers to identify sites where predators have killed prey, but this method has yet to be compared with scat analysis, a more traditional method of determining diet ...

Ecology and Evolution, 2019 Forage availability and predation risk interact to affect habitat use of ungulates across many biomes. Within sky‐island habitats of the Mojave Desert, increased availability of diverse forage and cover may provide ungulates with unique opportunities to ...

Human-Wildlife Interactions, 2017 Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population.

Cougar response to a gradient of human development
Ecosphere, 2017 Human populations continue to increase and transform Earth's ecosystems. For large carnivores, human development reduces habitat abundance, alters predator–prey dynamics, and increases the risk of mortality, which may threaten the viability of many ...
