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 period of 100 years Under mostplausible parameter values, the modelpre- dicted vety low extinction risk in areas as small as 2200 km2, and (in the absence of immigration) increasing risk as area decreased below 2200 km2. If as few as one to four animals per decade could immigrate into a small popula…

Modeling Cougar Corridors in the Owens Valley

Cougars, along with black bears and grey wolves, are the most significant apex predators in the lower forty-eight states of the United States. Currently they are at risk of population decline in many

Multiscale consensus habitat modeling for landscape level conservation prioritization

This work used location data and environmental variables to develop a consensus model using Maxent and Mahalanobis distance to identify black bear habitat across Florida, USA and suggests habitat is at risk of fragmentation.

Patch Size and Connectivity Thresholds for Butterfly Habitat Restoration

This work used incidence functions to predict long-term, stochastic, steady-state conditions and dispersal simulations to predict short-term (25-year) colonization dynamics and recommends selecting nearby sites when short- term colonization dynamics are expected to be an important aspect of a species' biology.

Modeling Disjunct Gray Wolf Populations in Semi‐Wild Landscapes

Gray wolves (Canis lupus) in parts of the United States and Europe live in networks of disjunct populations, many of which are close to human settlement. Because wolf management goals include

Designing a Conservation Landscape for Tigers in Human‐Dominated Environments

Abstract:  Wildlife populations in small, isolated reserves face genetic and demographic threats to their survival. To increase the probability of long‐term persistence, biologists promote

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



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,

Viable Populations for Conservation: Minimum viable population size in the presence of catastrophes

Until a generalized theory covering both concepts is attempted, confusion may arise by the loose transfer of a numerical value of the MVP from the genetic to the demographic case, particularly the genetically derived values offered by Franklin (1980) and Soule (1980).

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.

Survival Rates of Mountain Lions in Southern Utah

Analysis of longterm telemetry records and estimated survival rates for resident mountain lions using 2 techniques: MICROMORT (Heisey and Fuller 1985) and product-limit (Kurzejeski et al. 1987).

Notes on Cougar Productivity and Life History

Evidence is presented that some females apparently have young as often as 12–15 months, but a 2-year interval appears the rule, and most young apparently remain with their mothers for at least a year.

Panther conservation strategies must go beyond traditional land acquisition by government and include economic programs to preserve critical landscapes on private lank.
