Micro‐habitat selection by boreal woodland caribou improves access to food
Wildlife Biology, EarlyView.Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Effect of behavioral marginality on survival of an alpine ungulate
Ecosphere, 2019 Inter‐individual variability in behavior has been studied extensively for a wide range of species. However, few researchers have considered marginality, defined as the degree to which a choice made by an individual is located at the margins of the ...

Wolf predation in the Burwash caribou herd, southwest Yukon
Rangifer, 1986 The role of wolf predation as a proximate mortality factor influencing caribou herd growth was assessed in the Burwash herd (400 animals) in the southwest Yukon between 1980 - 1982.

Genetic connectivity of boreal woodland caribou (Rangifer tarandus caribou) in central Canada [PDF]
, 2015 Delineating population units is essential for the conservation and management of a species. Applying a genetic approach to delineate units, this study identifies genetic population structure, and landscape resistance to gene flow, of the nationally threatened boreal woodland caribou (Rangifer tarandus caribou) across the ecotypes’ southern range in ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Wildlife Biology, EarlyView.Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

The Buffalo of the North: Caribou (Rangifer tarandus) and Human Developments [PDF]
, 1984 The demography, movement, and behaviour patterns of eight caribou populations (Kaminuriak, Nelchina, Central Arctic, Fortymile, Porcupine, British Columbia, Newfoundland, and Snohetta) exposed to industrial activities or transportation corridors are ...

Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

The intrinsic rate of increase of reindeer and caribou populations in arctic environments
Rangifer, 1990 The intrinsic rate of increase of an animal population, rm, is specific to the environment in which it is measured. Previous estimates of maximum growth rates for reindeer and caribou Rangifer tarandus populations were based on introductions to islands ...
