Predicting favorable habitat for bobcats (Lynx rufus) in Iowa
<p>Bobcats (Lynx rufus), once common in the prairie-woodland mosaic of the Midwest, were largely extirpated from the Corn Belt region by 1900. In the 1990's, sightings of bobcats in Iowa began to increase, and they are now abundant in southern Iowa. With the dramatic expansion of rowcrop …

Space Use And Habitat Selection By Bobcats In Southeastern Kentucky
… same study area. I radio-collared five (4F, 1M) bobcats and assessed space and habitat use patterns. Mean annual minimum convex polygon (MCP) home range size for all bobcats was 14.7 km2 (n = 5, SE = 3.9 km2), and 22.2 km2 (n = 5, SE = 7.5 km2) using the adaptive kernel (AK) method. Mean female …

Food Habits and Placental Scar Counts of Bobcats in South Dakota
… used to determine litter size for South Dakota bobcats. Rabbits (Sylvilagus spp. and Lepus spp.), rats and mice (primarily Microtus spp. and Peromyscus spp.), and deer (Odocoileus spp.) were identified in 56, 32, and 7% of bobcat stomachs, respectively. Analysis showed that rabbits, rats and …

Population genetics and phylogeography of bobcats (Lynx rufus) using microsatellites and mitochondrial DNA
Bobcats (<italic>Lynx rufus<italic>) are generalist carnivores with an expansive range from southern Canada to northern Mexico, in which 11 - 12 subspecies have been described. Since European settlement, bobcat habitat has become increasingly fragmented due to urbanization and development of …

Habitat Selection and Population Ecology of Bobcats (Lynx Rufus) in South Dakota, USA
… Black Hills): (1) identify habitat selection by bobcats, (2) determine survival rates and cause of mortality of bobcats, (3) estimate potential population size, and (4) identify food habits of bobcats. From July 2006 to January 2010 we radio collared 10 bobcats in the Badlands (4 female, 6 male), …

Spatial Ecology of Bobcats (Lynx rufus) in the Appalachian Mountains of Western Virginia
Despite the prevalent distribution of bobcats in western Virginia and the broader region of Appalachia, there is a paucity of information on their spatial ecology in this region. Due to the unique ecological conditions of Appalachia, and increasing public interest surrounding the role of bobcats as …

Problem-solving capabilities as a test of predator adaptability: A comparision of bobcats (Lynx rufus) and Canada lynx (Lynx canadensis)
… lynx (<italic>Lynx canadensis</italic>) and bobcats (<italic>Lynx rufus</italic>) are two closely related felids occurring naturally in North America. Bobcats are generalized hunters across their range while Canada lynx are specialized to hunt lagomorphs, especially snowshoe hare …

Diet and Feeding Ecology of the Coyotes, Black Bears, and Bobcats in Western Virginia and Preliminary Assessment of Coyote Parasites
… other areas suggest that predation from coyotes, bobcats (Lynx rufus), and black bears (Ursus americanus) may be a significant source of deer (Odocoileus virginianus) mortality, especially for fawns, and the cumulative effects of predation from these sources may also increase the potential for …

Evaluation of Bobcat (Lynx rufus) Survival, Harvest, and Population Size in the West-Central Region of South Dakota
… managers to gather additional information about bobcats in South Dakota. From 2012–2015, we assessed population dynamics of bobcats occupying the west-central region of South Dakota. Our objectives were to: 1) estimate annual survival rates; 2) determine cause-specific mortality; 3) estimate a …

The status and dynamics of the bobcat population in Virginia
… seasons. Sex and age data on 41 additional bobcats taken in the 1977-78 and 1978-79 trapping seasons were provided by the Virginia Commission of Game and Inland Fisheries. The mean age from the 4-year pooled sample was 2.83 ± 0.24 (S.E.) years, with 25% juveniles, maximum age 12 years, and …

Mammalian carnivores as bioindicators to evaluate the exposure and bioaccumulation of organic contaminants in terrestrial ecosystems
… I opportunistically collected road-killed bobcats (n=44) throughout Illinois during 2013-2014, and analyzed their liver tissue for the presence of PCBs, PBDEs, and various other alternative halogenated flame retardants. Concentrations of ∑PCBs ranged from 76.4 ng/g lw to 3782 ng/g lw …

FACTORS INFLUENCING THE SPATIAL AND TEMPORAL STRUCTURE OF A CARNIVORE GUILD IN THE CENTRAL HARDWOOD REGION
… patterns in ecosystems. Coyotes (Canis latrans), bobcats (Lynx rufus), gray foxes (Urocyon cinereoargenteus), raccoons (Procyon lotor), red foxes (Vulpes vulpes), and striped skunks (Mephitis mephitis) occur sympatrically throughout much of their geographic ranges in North America and overlap in …

Lynxrufus wilsoni n.g., n.sp. (Nematoda: metastrongylidae) from the lungs of the bobcat, Lynx rufus rufus (Shreber)
Of sixty-four bobcats, Lynx rufus rufus, collected in Virginia end North Carolina, twenty-five percent were found to be infected with an unidentified lungworm. As the literature showed no record of lungworm parasites from Lynx rufus rufus, a study was made of the lungworms of the cat family, …

Effects of forest management, prey, and predators on the habitat selection of fishers in the South Cascades of Washington.
… food-safety tradeoff for fishers between bobcats (Lynx rufus) and snowshoe hares, which fishers may mediate through temporal avoidance of bobcats. Selection for old forests close to recently disturbed stands and the preference of important prey for young stands suggests that habitat …

Carnivore Modification in North America: Perspectives on Neotaphonomy, Carnivore Use of Carrion, and Great Plains Bison Bonbeds
… North American wolves, coyotes, mountain lions, bobcats, grizzly bears, and black bears were fed defleshed hind limbs of cattle (Bos taurus) and lamb (Ovis aries). Wolves displayed behaviors that include use of incisors for pulling soft tissue, and use of cheek teeth for gnawing at bones and soft …
