Mountain lion management and conservation efforts should be individualized according to region and incorporate landscape-level considerations to protect habitat and connectivity, and to prevent population declines and loss of genetic variation.
Molecular tracking of mountain lions in the Yosemite Valley region in California: genetic analysis using microsatellites and faecal DNA
This analysis provided a minimum estimate of 16 mountain lions living in or travelling through Yosemite Valley from March 1997 to August 1998, and demonstrated that faecal DNA analysis is an effective method for detecting and identifying individual mountain lions.
PREVALENCE OF BOVINE TUBERCULOSIS IN AFRICAN BUFFALO AT KRUGER NATIONAL PARK
Monitoring of BTB in Kruger National Park is important for understanding disease transmission risks, potential population effects, and the efficacy of disease management strategies, and a stratified, two-stage cluster sampling method was used in 1998.
Bartonella spp. isolated from wild and domestic ruminants in North America.
Findings indicate potential for inter- and intraspecies transmission among ruminants, as well as risk that these Bartonella spp.
Multi-level, multi-scale resource selection functions and resistance surfaces for conservation planning: Pumas as a case study
This work contends it is not an either/or issue and that resistance may be better-modeled using a combination of resistance surfaces that represent processes at different hierarchical levels, and develops a conservation plan for one of the most isolated puma populations in the U.S.

Estimating landscape resistance to animal movement is the foundation for connectivity modeling, and resource selection functions based on point data are commonly used to empirically estimate…
Estimating sizes of wild pig populations in the North and Central Coast regions of California
Densities increased from 1994 to 1995, potentially related to higher rainfall and increased forage availability in 1995, and densities were lower in areas with relatively high hunting pressure, suggesting that sport hunting may be effective at reducing wild pigs numbers in some areas.
Genetic variation of major histocompatibility complex and microsatellite loci: a comparison in bighorn sheep.

Results indicated that neutral forces substantially influenced MS and MHC variation, and they provided limited evidence for selection acting on the MHC.
Cross-seasonal patterns of avian influenza virus in breeding and wintering migratory birds: a flyway perspective.
This study characterized spatio-temporal infection patterns in 10,389 waterfowl at two important locations within the Pacific Flyway and shed light on how the dynamics of AIV infection of wild bird populations can vary between the two ends of a migratory flyway.
Interfacing models of wildlife habitat and human development to predict the future distribution of puma habitat
The impact of human land uses on ecological systems typically differ relative to how extensively natural conditions are modified. Exurban development is intermediate-intensity residential development…
