Abstract: Urbanization and habitat fragmentation are major threats to wildlife populations, especially mammalian carnivores. We studied the ecology and behavior of bobcats ( Lynx rufus ) and…
Evaluation of survival and cause-specific mortality rates using telemetry data
Methods for estimating survival and cause-specific mortality rates from radiomarked animals from telemetry data are presented and potential biases arising from combining data from several individuals marked at different times within an interval or from combining rates from different intervals are identified.
FAST‐TRACK: A southern California freeway is a physical and social barrier to gene flow in carnivores

The results demonstrate that freeways can restrict gene flow even in wide‐ranging species and suggest that for territorial animals, migration levels across anthropogenic barriers need to be an order of magnitude larger than commonly assumed to counteract genetic differentiation.

Pathogens, Nutritional Deficiency, and Climate Influences on a Declining Moose Population
Analysis of protein content in moose browse and fecal samples indicated that food quality was probably adequate to support moose over winter, but the higher fecal protein among animals that died in the subsequent 18 months could be indicative of protein catabolism associated with malnutrition, which may have contributed to moose mortality.
Competition and intraguild predation among three sympatric carnivores

It is proposed that coyotes limit the number and distribution of gray foxes in Santa Monica Mountains, and that those two carnivores exemplified a case in which the relationship between their body size and local abundance is governed by competitive dominance of the largest species rather than by energetic equivalences.
Does availability of anthropogenic food enhance densities of omnivorous mammals? An example with coyotes in southern California
- J. Fedriani, T. Fuller, R. Sauvajot

To evaluate whether the abundance of coyotes Canis latrans was influenced by the availability of anthropogenic foods in a humanized landscape, we compared three neighboring areas (hereafter referred…
Infectious disease and the conservation of free‐ranging large carnivores

It is concluded that the threat of disease epidemics in large carnivores may be serious if otherwise lethal infections are endemic in reservoir hosts and transmitted horizontally among taxa.
