Conflict, coexistence, or both? Cougar habitat selection, prey composition, and mortality in a multiple-use landscape
30 November 2020
;Western North America is experiencing remarkable human population growth and land-use change. Irrigation and associated cultivation have led to colonization of urban-wildland interface (UWI) environments by...
>Predictors of puma occupancy indicate prey vulnerability is more important than prey availability in a highly fragmented landscape
2020
;Habitat fragmentation represents the single greatest conservation challenge of the 21st century. This problem is particularly acute for large, obligate carnivores like pumas Puma concolor which...
>Effects of land-use change and prey abundance on the body condition of an obligate carnivore at the wildland-urban interface
August 27 2019
;Land-use change represents a primary driver of carnivore population declines, yet some large carnivore species have acclimated and persist within anthropogenically altered landscapes. Previous attention has been...
>Evidence of spatial genetic structure in a snow leopard population from Gansu, China
2021
;Understanding the spatial structure of genetic diversity provides insights into a populations’ genetic status and enables assessment of its capacity to counteract the effects of genetic drift. Such...
>Roadkill Distribution at the Wildland‐Urban Interface
10 April 2019
;The growing wildland‐urban interface is a frontier of human‐wildlife conflict worldwide. Where natural and developed areas meet, there is potential for negative interactions between humans and...
>Urban wildlife use of existing highway crossings and access points
Submitted 20 March 2019
;Roads and traffic are a significant source of mortality for many wildlife species and compromise habitat integrity. Despite widespread recognition that maintaining or restoring wildlife population connectivity is...

Big Cats in Our Backyards:
Persistence of Large Carnivores in a Human Dominated Landscape in India
March 6, 2013
;Protected areas are extremely important for the long term viability of biodiversity in a densely populated country like India where land is a scarce resource. However, protected areas...
>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...

The size of savannah Africa:
a lion’s (Panthera leo) view
January 2013
;We define African savannahs as being those areas that receive between 300 and 1,500 mm of rain annually. This broad definition encompasses a variety of habitats. Thus...
