Population distribution and seasonal resource selection by elk (Cervus Elaphus) in Central Ontario
… population structure and resource selection of elk (Cervus elaphus) in central Ontario. I used fuzzy and hierarchical cluster analyses to elucidate elk population structure based on spatial data collected from 41 radio-collared elk. I assessed impacts of habitat quality on space use using the …

Genetic variability, demography, and habitat selection in a reintroduced elk (Cervus elaphus) population
… vital rates, and habitat use for a reintroduced elk (Cervus elaphus) population at Fort Riley, Kansas based on data collected from 2003 – 2007. Levels of allelic richness, observed heterozygosity, and expected heterozygosity for the Fort Riley population were intermediate to other North American …

Elk (Cervus elaphus) response to anthropogenic disturbance: hunting, land use, and climate change
… landscape conditions. During the past 50 years, elk in eastern Washington have expanded their year-long ranges into lower elevation areas of the Channeled Scablands. The persistence of this population is dependent upon core protected areas with surrounding low human density agriculture or …

Modeling Sex-Specific Seasonal Habitat Selection for Elk (Cervus Elaphus) in Central Washington
Elk (<em>Cervus elaphus</em>) are generalist herbivores, exploiting a variety of environments. I studied habitat selection and sexual segregation of the Colockum elk herd in central Washington. I used a resource selection probability function (RSPF) to evaluate habitat use by males and females …

Drivers of a Temporal Change in the Adult Sex Ratio of a Population of Roosevelt elk (Cervus elaphus roosevelti)
… My study examined a population of Roosevelt elk (Cervus elaphus roosevelti) inhabiting the Redwood National and State Parks, California. I sought to discern which of two potential ecological mechanisms could explain the female-biased ASR. The first mechanism was that increasing female …

Elk hunting on Turnbull National Wildlife Refuge: impacts on elk movement and aspen regeneration
… diversity of native plants and animals. When elk (Cervus elaphus) become overabundant, browsing prevents aspen regeneration, reduces survival, and consequently impacts local biodiversity. Given this, Turnbull National Wildlife Refuge (TNWR) initiated a limited annual elk hunt beginning in fall …

Food Supply Early in the Plant Growing Season: Influences from Elk Abundance and Precipitation
… food supply for a non-migratory population of elk (Cervus elaphus) in a temperate rainforest over a 15-year period when population abundance and total precipitation varied. The food supply was a 50-hectare meadow complex that was divided into 7 sectors, 2-10 hectares in size. I compared linear …

The Humoral Immune Response of Elks (Cervus elaphus nelsoni) and Mice to Vaccination with Brucella abortus Strain RB51
… to detect anti-RB51 antibodies in vaccinated elk (Cervus elaphus nelsoni), 2) to identify potential antigenic alterations in RB51 after vaccination of elk and BALB/c mice, and 3) to confirm the general stability of RB51. Elk were divided into four groups based upon gender and the route of …

Home range behavior of Roosevelt elk in Strathcona Park
… and home rangesizes of 5 groups of Roosevelt elk (Cervus elaphus roosev -It) in 4 regions of Strathcona Provincial Park on Vancouver Island, British Columbia. Ten elk were successfully radio-collared and re-located for 12-21 months, beginning in March 1991, and ending in January 1993. Eight of …

Development of An Elk Sightability Model for the Black Hills of South Dakota
Elk (Cervus elaphus) are important in the Black Hills of South Dakota because they are a prized game species, but also have negative impacts on private landowners through crop depredation. As a result, elk abundance is essential information required to successfully manage this population. …

Effect of Scale on Habitat Selection of Female White-Tailed Deer in the Central Black Hills, South Dakota and Wyoming
… forbs and shrubs suggested that competition by elk (Cervus elaphus) and cattle was important. Furthermore, deer apparently avoided areas of human disturbance adjacent to roads and houses. At the plot scale, thickets were important to deer. Utility of thickets was reduced by proximity to roads. …

Impacts of elk management and riparian condition on songbirds in Rocky Mountain National Park
… (Canis lupus) and an exponential increase in elk (Cervus elaphus). In 2008, RMNP began installing elk exclosures to protect and restore willow communities and the diverse taxa that depend on riparian ecosystems from heavy browsing. Using point counts, I evaluated the effect of elk exclosures …

Population Ecology of Rocky Mountain Elk in the Black Hills, South Dakota and Wyoming
… using individually marked adult cow and neonate elk (Cervus elaphus) occupying the southwestern region of the Black Hills. We used known-fate analysis in Program MARK for survival analysis of adult cows and calves. We estimated survival and cause-specific mortality of 49 adult female elk over the …

Big Game Habitat Utilization in Noncommercially Thinned Ponderosa Pine in Custer State Park
… utilization of forages in thinned pine stands by elk (Cervus elaphus), mule deer (Odocoileus hemionus), and white-tailed deer (Odocoileus yirginianus). The study was conducted in the northwest corner of the park during June, July, and August of 1991 and 1992. The study area included approximately …

HUMAN PREDATION RISK AND ELK BEHAVIOR IN HETEROGENEOUS LANDSCAPES
Elk (Cervus elaphus) are increasing in fragmented landscapes that result from exurban human development throughout western North America. This problem is increasing human-wildlife conflicts and represents a significant new challenge to wildlife managers. Elk hunting must be intensively managed, if …

Effects of predator urine on deterring ungulate browsing of aspen on the Turnbull National Wildlife Refuge
… aspen regeneration is of high priority. The elk (Cervus elaphus) population on TNWR has greatly increased over the last decade and over browsing is attributed as a factor affecting aspen regeneration. In response to the decline of aspen regeneration, TNWR initiated an elk hunt in 2010 to cull …
