Variation in cougar (Puma concolor) predation habits during wolf (Canis lupus) recovery in the southern Greater Yellowstone Ecosystem
; February 8, 2013
We examined predation habits of cougars (Puma concolor (L., 1771)) following the recent recovery of gray wolves (Canis lupus L., 1758) in the southern Greater Yellowstone Ecosystem. With...
De facto refugia, ecological traps and the biogeography of anthropogenic cougar mortality in Utah
; January 30, 2013
Modern extirpations within the Carnivora have generally followed the human footprint. The contagion hypothesis predicts that range contractions should occur along gradients in human activity, leaving relict populations...
The effects of puma prey selection and specialization on less abundant prey in Patagonia
; January 18, 2013
Populations of generalist foragers may in fact be composed of individuals that select different prey. We monitored 9 pumas (Puma concolor) in Chilean Patagonia using Argos–global positioning...
Nuisance Ecology:
Do Condors Exact Foraging Costs on Pumas in Patagonia?
; January 3, 2013
We tested whether Andean condors influenced the foraging behaviors of a top predator in Patagonia, the puma (Puma concolor), in ways comparable to direct risks of predation for...
Rapid assessment of linear transport infrastructure in relation to the impact on landscape continuity for large ranging mammals
; January 2013
Many Eastern European countries still host landscapes with high value due to their habitat quality and size. Some of these countries are new member states of the European...
Birth Timing for Mountain Lions; Testing the Prey Availability Hypothesis
; September 24, 2012
We investigated potential advantages in birth timing for mountain lion (Puma concolor) cubs. We examined cub body mass, survival, and age of natal dispersal in relation to specific...
Puma spatial ecology in open habitats with aggregate prey
; September 2012
Solitary felids are commonly associated with structurally complex habitats, where their foraging success is attributed to stealth and remaining undetected by competitive scavengers. Research in North America suggests...
Table scraps:
inter-trophic food provisioning by pumas
; June 13, 2012
Large carnivores perform keystone ecological functions through direct predation, or indirectly, through food subsidies to scavengers or trophic cascades driven by their influence on the distributions of their...
Impact of vehicular traffic on the use of highway edges by large mammals in a south indian wildlife reserve
; April 10, 2012
India’s phenomenal economic growth over the last decade has been accompanied by a much-needed expansion and improvement in transport and other infrastructure networks. While there are...
The Garnet Range Mountain Lion Study:
Characteristics of a Hunted Population in West-Central Montana
; December 31, 2011
Large carnivores pose a particular challenge in wildlife management. Their importance in ecosystem function is increasingly well documented, while at the same time their potential for conflict with...
Cougar survival and source-sink structure on Greater Yellowstone's Northern Range
; July 18, 2011
We studied survival and causes of mortality of radiocollared cougars (Puma concolor) on the Greater Yellowstone Northern Range (GYNR) prior to (1987–1994) and after wolf (Canis lupus)...
Trophic Downgrading of Planet Earth
; 15 July 2011
Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind’s most pervasive...
