occurrence of puma lentivirus infection in cougars from washington.	puma lentivirus (plv) antibodies were detected in 13 (25%) of 52 serum samples obtained from cougars (felis concolor) collected by hunters. the serum samples were collected from november 1993 through january 1994 from four specific regions throughout the state of washington (usa), and included the olympic mountains, the cascade mountains, the blue mountains, and the selkirk mountains. more (38%) seropositive cougar samples originated from the cascade mountains than from any other site. the overa ...	1997	9131566
vitamin a concentrations in serum and liver from florida panthers.	many of the anomalies and clinical signs afflicting the florida panther (felis concolor coryi) are suggestive of vitamin a deficiency. our objectives in this study were to determine if a vitamin a deficiency exists in the free-ranging panther population and to determine if there are differences in vitamin a levels among various subgroups of free-ranging panthers. retinol concentrations were used as an index to vitamin a concentrations and were determined in serum and liver from free-ranging (ser ...	1999	10231743
does hunting regulate cougar populations? a test of the compensatory mortality hypothesis.	many wildlife species are managed based on the compensatory mortality hypothesis, which predicts that harvest mortality (especially adult male mortality) will trigger density-dependent responses in reproduction, survival, and population growth caused via reduced competition for resources. we tested the compensatory mortality hypothesis on two cougar (puma concolor) populations in washington, usa (one heavily hunted and one lightly hunted). we estimated population growth, density, survival, and r ...	2009	19886499
