The Status of the Puma (Puma Concolor) in Missouri, Based on Sightings
Since 1927, the puma (Puma concolor) has been classified as extirpated from the state of Missouri. However, sightings of puma have continuously been reported thorughout the state. Questionnaires, addressing the circumstances of the sighting incident and personal attributes of the individual, were …

Ecology of Mountain Lions (Puma concolor) in the North Dakota Badlands: Population Dynamics and Prey Use
Mountain lions (Puma concolor) have recently recolonized the North Dakota Badlands nearly a century after their extirpation; due to the relatively recent reappearance of mountain lions in the region, most population metrics are unknown. From 2011‒2013, we fitted 14 mountain lions with GPS collars …

The influence of habitat features and co-occurring species on puma (Puma concolor) occupancy across eight sites in Belize, Central America
… behavior) make them difficult to monitor. Pumas have been particularly difficult to study because the lack of distinctive markings on their coats prevents individual identification, precluding mark-recapture and other similar analyses. Further, compared to temperate areas, research on the …

Determining habitat and biotic factors driving puma (<i>Puma concolor</i>) space use and underlying dynamic processes (colonization and extinction) over 20 years in protected and private areas throughout Belize, Central America
… there is relatively scant information on pumas (<i>Puma concolor</i>) in the neotropics especially compared to the more well-studied jaguar (<i>Panthera onca</i>). Understanding long-term puma distribution can affect land management decisions such as appropriate size of buffer zones around …

Space Use and Survival of White-Tailed Deer in a Disturbance-Driven System Containing a Restored Apex Predator
… and increased abundances the Florida panther (Puma concolor coryi), their primary predator in this system, call for a renewed look at how these forces affect this deer herd. To assess the effects of these forces on seasonal space use, behavior, and survival of deer, I analyzed GPS telemetry and …

Lead exposure in large carnivores in the greater Yellowstone ecosystem
… as a food source while others, such as cougars (Puma concolor), avoid areas with high levels of human hunting pressure. I investigated whether large carnivores in the Greater Yellowstone Ecosystem were exposed to lead, and if so, if ammunition ingested from hunter-harvested gut piles was an …

Effective monitoring techniques for carnivores and the role of a dominant mesocarnivore in structuring the carnivore community
… I then compared two similar ecosystems, one with pumas (Puma concolor) and one without using spatial and temporal analyses to determine if coyotes, a dominant mesocarnivore, filled the functional role of an apex predator in the absence of pumas, a true apex predator. I found that sardines …

Technology in ecology: determining the location, behaviour, and energy expenditure of free-ranging carnivores
… how large wild predators, mountain lions (Puma concolor), minimise energetic costs in increasingly isolated, challenging terrains.<br/><br/>I found that the accuracy of animal routes derived from GPS decrease with longer intervals between fixes and with faster animal speeds, but …

Monitoring Program and Assessment of Coyote Predation for Olympic Marmots
… 10% from bobcat (Lynx rufus) and 5% from cougar (Puma concolor). Twelve out of 13 coyote individuals identified with genetic markers included marmots in their diet. Overall, occurrence of marmot remains in coyote scats observed could be considered high, especially if relatively low marmot …

Noninvasive tracking of jaguars (Panthera onca) and co-occurring Neotropical felids in Belize, Central America by genotyping feces and remote camera trapping
… multi-locus data in jaguars (Panthera onca), pumas (Puma concolor) and ocelots (Leopardus pardalis) collected from 1053 scat samples across their range in the country. First, we optimized 14 polymorphic microsatellite loci for jaguars (Panthera onca), pumas (Puma concolor), and ocelots …

Determining Impacts of Mountain Lions on Bighorn Sheep and Other Prey Sources in the Black Hills
<p>From 2009 to 2013, we assessed cougar (Puma concolor) feeding habits and bighorn sheep (Ovis canadensis) population dynamics in the Black Hills, South Dakota. We used Global Positioning System (GPS) telemetry to locate 1,506 cougar feeding events and found deer (Odocoileus spp.; 83%), primarily …

Short-term effects of wildfire on Sierra Nevada bighorn sheep habitat ecology

In the first year post-wildfire, Sierra bighorn increased selection for new growth herbaceous biomass in response to the reduced biomass caused by wildfire. While wildfire initially reduced total …
