We examined cougar ( Puma concolor ) dispersal, emigration, and immigration in the San Andres Mountains, New Mexico, from 1985 to 1995 to quantify the effects of dispersal on the local population and surrounding subpopulations. [] Key Method We captured, tagged, and radio-collared animals to detect the arrival of new immigrants and dispersal characteristics of progeny. We found that cougars in southern New Mexico exhib- ited a metapopulation structure in which cougar subpopulations were separated by expanses…

Dispersal movements of subadult cougars from the Black Hills: the notions of range expansion and recolonization

Dispersal plays a vital role in cougar (Puma concolor) population ecology, creating genetic viability and maintaining gene flow between populations. The naturally recolonized cougar population in the

Space-use, movement and dispersal of sub-adult cougars in a geographically isolated population

Although certain habitat characteristics were preferred, transient and localizing cougars used fast-paced nocturnal movements and shortened daytime movements when traversing open habitats to effectively limit their residency and exposure in less-suitable landscapes.

Cougar Dispersal and Natal Homing in a Desert Environment

Abstract. We present a review of cougar dispersal literature and the first evidence of natural (i.e., unmanipulated) homing behavior by a dispersing male cougar (Puma concolor) that sustained severe


Based on measures of gene flow, extinction risk in the near future appears low and Bayesian assignment to population based on individual genotypes showed that cougars in this region were best described as a single panmictic population.

Long-Distance Dispersal of a Female Cougar in a Basin and Range Landscape

Abstract We used Global Positioning System technology to document distance, movement path, vegetation, and elevations used by a dispersing subadult female cougar (Puma concolor) through the

Cougar Exploitation Levels in Utah: Implications for Demographic Structure, Population Recovery, and Metapopulation Dynamics

Abstract Currently, 11 western states and 2 Canadian provinces use sport hunting as the primary mechanism for managing cougar (Puma concolor) populations. Yet the impacts of sustained harvest on

Density-Dependent Natal Dispersal Patterns in a Leopard Population Recovering from Over-Harvest

It is concluded that conservation interventions that facilitated local demographic recovery in the study area also restored dispersal patterns disrupted by unsustainable harvesting, and that this indirectly improved connectivity among leopard populations over a larger landscape.

Potential cougar habitats and dispersal corridors in Eastern North America

Context Cougars ( Puma concolor ) have been recolonizing Midwestern North America during the past 3 decades with > 950 cougar confirmations east of established populations. Due to an increase in



Dispersal of juvenile cougars in fragmented habitat

Investigation of dispersal of radio-tagged juvenile cougars in a California landscape containing 3 corridors found them to use corridors that are located along natural travel routes, have ample windy cover, include an underpass integrated with roadside fencing at high-speed road crossings, and lack artificial outdoor lighting.

Population Characteristics and Movement Patterns of Cougars in Southern Utah

Twenty-two cougars (Felis concolor) were monitored by radiotelemetry between January 1979 and July 1981 in southern Utah. The population, comprised of resident, transient, and juvenile cougars,

Cougar Population Dynamics in Southern Utah

Results supported the hypothesis that cougar density is set by environmental features other than prey abundance alone.

Mammalian Dispersal Patterns: The Effects of Social Structure on Population Genetics

Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior

Determining Minimum Habitat Areas and Habitat Corridors for Cougars

I simulated population dynamics of cougars to predict tbe minimum areas and levels of immigration needed to avoid population extinction caused by demo- graphic and environmental stochasticity for a

Characteristics of a Hunted Mountain Lion Population in Wyoming

Characteristics of a hunted mountain lion population in the Big Horn Mountains, Wyoming, from June 1981 to July 1983 are reported by the lack of detailed biological data on lions in Wyoming; information previously was limited to general status reports.

Resilience and conservation of large carnivores in the Rocky Mountains

Large carnivores evolved behaviors and life-history traits that conferred resilience to environmental disturbances at various temporal and spatial scales. We synthesize empirical information for each

The practical need in biological conservation for understanding the interaction of demographic and genetic factors in extinction may provide a focus for fundamental advances at the interface of ecology and evolution.

Comparative ecology of bobcat, black bear, and Florida panther in south Florida

Comparisons of food habits, habitat use, and movements revealed a low probability for competitive interactions among bobcat (Lynx ndia). Florida panther (Puma concotor cooi 1 and black bear (Urns
