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 |
trichinella infection in wildlife of the southwestern united states. | several potential mammalian reservoirs of sylvatic species of trichinella were examined from texas, new mexico, and arizona. during 1998-99, tongues were collected from a black bear (ursus americanus) in arizona; from 9 black bears, a coyote (canis latrans), and a mountain lion (felis concolor) in new mexico; and from 154 coyotes, 32 raccoons (procyon lotor), 13 opossums (didelphis marsupialis), 4 ocelots (leopardus pardalis), 3 bobcats (lynx rufus), and 5 feral hogs (sus scrofa) in southern tex ... | 2001 | 11695403 |
seroprevalence of toxoplasma gondii in american free-ranging or captive pumas (felis concolor) and bobcats (lynx rufus). | toxoplasma gondii is a major zoonotic agent infecting a wide range of mammals, including wild felids. like domestic cats, wild felids are involved in the complete infective cycle of t. gondii, as they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. in order to evaluate the importance of this wildlife reservoir, 438 serum samples collected between 1984 and 1999 from 438 pumas (felis concolor) and from 58 bobcats (lynx rufus) from north ... | 2004 | 15019138 |
the rise and fall of psoroptic scabies in bighorn sheep in the san andres mountains, new mexico. | between 1978 and 1997, a combination of psoroptic scabies (psoroptes spp.), mountain lion (puma concolor) predation, and periodic drought reduced a population of native desert bighorn sheep (ovis canadensis) in the san andres mountains (sam), new mexico, from >200 individuals to a single ewe. in 1999, this ewe was captured, ensured to be psoroptes-free, and released back into the sam. eleven radio-collared rams were translocated from the red rock wildlife area (rrwa) in new mexico into the sam r ... | 2005 | 16244062 |
models of regional habitat quality and connectivity for pumas (puma concolor) in the southwestern united states. | the impact of landscape changes on the quality and connectivity of habitats for multiple wildlife species is of global conservation concern. in the southwestern united states, pumas (puma concolor) are a well distributed and wide-ranging large carnivore that are sensitive to loss of habitat and to the disruption of pathways that connect their populations. we used an expert-based approach to define and derive variables hypothesized to influence the quality, location, and permeability of habitat f ... | 2013 | 24367495 |
habitat barriers limit gene flow and illuminate historical events in a wide-ranging carnivore, the american puma. | we examined the effects of habitat discontinuities on gene flow among puma (puma concolor) populations across the southwestern usa. using 16 microsatellite loci, we genotyped 540 pumas sampled throughout the states of utah, colorado, arizona, and new mexico, where a high degree of habitat heterogeneity provides for a wide range of connective habitat configurations between subpopulations. we investigated genetic structuring using complementary individual- and population-based analyses, the latter ... | 2005 | 15910319 |
