Control of LH secretion in red deer (Cervus elaphus)
… on the pulsatile secretion of LH in red deer (Cervus elaphus). In the first experiment two groups of long-term ovariectomized hinds (n=10, with and without intravaginal progesterone pre-treatment) were injected i.m. with 0, 5, or 100 µg oestradiol-17β, 24 h after the withdrawal of progesterone …

Genetic variability, demography, and habitat selection in a reintroduced elk (Cervus elaphus) population
… 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 …

Elk (Cervus elaphus) response to anthropogenic disturbance: hunting, land use, and climate change
"Understanding factors underlying the distribution and abundance of wildlife species remains a central question of wildlife ecology and has become increasingly complex as humans continue to alter landscape conditions. During the past 50 years, elk in eastern Washington have expanded their year-long …

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 …

The interaction of Sika deer (Cervus nippon Temminck 1838) with lowland heath mosaics.
Sika deer (Cervus nippon) has become an invasive species in many parts of the world. In the south of England large populations appear to be concentrated in landscapes comprising of mosaics of lowland heath, woodlands and grassland. Despite the association between the distribution of Sika deer and …

The activity and functioning of the hypothalamic-pituitary-adrenal axis of the red deer stag (cervus elaphus)
The activity and functioning of the HPA axis was investigated in red deer stags under basal and stress induced conditions. In order to overcome the confounding effects of stress inherent in standard methods of blood collection, a portable remote blood sampling device (“DracPac”) was developed and …

The Humoral Immune Response of Elks (Cervus elaphus nelsoni) and Mice to Vaccination with Brucella abortus Strain RB51
… 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 …

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 abundance …

Linking environmental variation across the Scottish Highlands with red deer (Cervus elaphus) trace element status, parasite burden, and skeletal morphometry
… to remote and rural economies. Wild red deer (Cervus elaphus) in the Scottish Highlands have long been recognised as occupying a sub-optimal (i.e., limiting) environment in terms of nutrition and shelter. Despite this wide recognition, no studies regarding the population have extensively …

Étude paléogénétique du cerf élaphe (Cervus elaphus) au cours de la transition Tardiglaciaire - Holocène ancien du Jura (15 000 – 6 000 BP) : relations entre changements morphologiques, environnementaux et génétiques
… survey has been led on bones from Red Deer, Cervus elaphus, found in the shelter associated with remains of lithic industry and prehistoric art let by the hunters-gatherers during this unstable time. Isotopic geochemistry has already showed that during this period, the habitat and the diet of …

The elk in Virginia
Formerly, the elk or Wapiti, Cervus canadensis L., ranged over most of the United States and southern Canada, and is known to have occurred throughout most of Virginia, although it was found more abundant in the mountainous regions of the Allegheny and Blue Ridge Ranges. In 1666, twelve years after …

Elk hunting on Turnbull National Wildlife Refuge: impacts on elk movement and aspen regeneration
… 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
… 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 mixed …

Authentication of Species in Bison Products Using Molecular Methods
… as bison, 1 was identified as red deer (<em>Cervus elaphus</em>) and 3 were positive for cattle. The results of PCR-SFLP confirmed the presence of cattle for 2 of the 3 samples identified as cattle with DNA barcoding. Overall, 3 of the 45 samples (6.7%) were determined to be mislabeled. This …

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. …
