Dynamique des populations de caribous migrateurs (Rangifer tarandus) basée sur des indices de condition corporelle
… body size and condition. Migratory caribou ( Rangifer tarandus ) are a keystone species in the tundra. Populations can fluctuate drastically and rapidly and are challenging to monitor and manage. As an alternative to population estimates, indirect ecological indicators, which are …

Behavioural Ecology in Conservation Planning: Individual and Sex-Specific Insights from Woodland Caribou (Rangifer tarandus caribou) in Western Canada
… can inform conservation of woodland caribou (Rangifer tarandus caribou), a threatened species with complex population structure and widespread declines across western Canada. Leveraging a long-term (2000 – 2025) broad-scale GPS telemetry dataset from over 1000 individuals across multiple …

An Assessment of Caribou (Rangifer tarandus) Genomic Diversity and Structure in Western Canada to Guide Species Conservation and Management
… population declines. Particularly for caribou (Rangifer tarandus), which are considered an at-risk species across Canada, determining population genetic structure can help delineate units for conservation while detecting potentially cryptic population structure and diversity as well as …

Population dynamics and demography of reindeer (Rangifer tarandus L.) on the East Iceland highland plateau 1940–2015 A comparative study of two herds
In 1787, 35 domestic reindeer (Rangifer tarandus) were introduced to northeast Iceland from Norway and have roamed wild since then. They increased and dispersed in the 19th century but in 1939 only few persisted in East Iceland. Thereafter the herd increased and dispersed all over East Iceland. The …

Multi-isotope analysis and the reconstruction of prey species palaeomigrations and palaeoecology
… ecology and biogeography. Modern caribou (Rangifer tarandus ssp.) and bison (Bison bison) from North America are used to assess the relationship between known lifetime movements and feeding habits, and those reconstructed through the stable isotope analysis of teeth and bone, including …

Potential impacts of sea ice and ship traffic change to caribou sea ice crossing areas surrounding King William Island, Nunavut, Canada
Caribou (Rangifer tarandus, tuktuit in Inuktitut) use sea ice to facilitate movements that fulfill their ecological needs. Ship traffic is growing in the Kitikmeot region of Nunavut, and ice-strengthened ships can disrupt sea ice by breaking it apart. This project explored priorities identified by …

The Devil's in the Diversity: Divergent Parasite Faunas and their Impacts on Body Condition in Two Greenland Caribou Populations
… in two populations of west Greenland caribou (Rangifer tarandus groenlandicus). Parasite diversity was described using fecal flotations and examinations of abomasa and small intestines. Anoplocephalidae, Nematodirinae and “Strongyle”-type eggs and Eimeria oocysts were found in fecal samples …

A Systematic and Taphonomic Analysis of Late Pleistocene Cervid Remains and Isotopic Paleoecology of Herbivores from Guy Wilson Cave, Southern Appalachians, Tennessee
… remains: <em>Odocoileus virginianus</em>, <em>Rangifer tarandus</em>, and either <em>Cervalces scotti</em> or <em>Alces alces</em>. Separation of <em>Cervalces</em> and <em>Alces</em> based on the dental material was not possible. Taphonomic analysis of gnawing and tooth markings showed …

Habitat Selection and Range Overlap of Moose and White-tailed Deer in the Boreal Plains of Saskatchewan
… deer (Odocoileus virginianus), boreal caribou (Rangifer tarandus caribou), and wolves (Canis lupus). White-tailed deer, historically uncommon in boreal forests, have expanded their range over the past 50 years. This expansion raises concerns about apparent competition, where one species …

Resource selection and abundance estimation of moose: Implications for caribou recovery in a human altered landscape
Woodland caribou (Rangifer tarandus caribou) are threatened across Canada due to human disturbance altering predator-prey dynamics. The niche specialization of caribou enables them to survive in nutrient-poor habitats spatially separated from other ungulates and their shared predators. The …

Resource selection, predation risk, and population dynamics of woodland caribou
<p>Woodland caribou (Rangifer tarandus caribou) have experienced population declines and local extirpations across North America. Human disturbance has caused caribou declines indirectly through changes to apparent competition dynamics within the predator-prey community. Apparent competition occurs …

Assessing cumulative human impacts on northern woodland caribou with traditional ecological knowledge and resource selection functions
Woodland caribou (Rangifer tarandus caribou) are federally listed and declining across Canada because of the cumulative impacts of human infrastructure development. The Atlin northern mountain herd, in the territory of the Taku River Tlingit First Nation (TRTFN), British Columbia, is less affected …

Differential habitat selection of black bears, gray wolves, and boreal caribou in the Boreal Shield of Saskatchewan
Boreal woodland caribou (Rangifer tarandus caribou) are listed as Threatened on Schedule 1 of the Canada Species at Risk Act, and critical habitat for this species is currently being defined across the country. Declines in populations have been driven largely by anthropogenic disturbance, and in …
