Radiocarbon Chronologies and Extinction Dynamics of the Late Quaternary Mammalian Megafauna of the Taimyr Peninsula, Russian Federation [PDF]

, 2002
This paper presents 75 new radiocarbon dates based on late Quaternary mammal remains recovered from eastern Taimyr Peninsula and adjacent parts of the northern Siberian lowlands, Russian Federation, including specimens of woolly mammoth (Mammuthus ...

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 ...

Insect avoidance may override human disturbances in reindeer habitat selection

Rangifer, 2004
Habitat selection of semi-domesticated reindeer (Rangifer tarandus tarandus) was investigated through faecal pellet- group counts and by direct observations of reindeer from helicopter in the Långfjället area in Idre reindeer herding district (62˚10’N ...

Experimental oral transmission of chronic wasting disease to reindeer (Rangifer tarandus tarandus). [PDF]

PLoS ONE, 2012
Chronic wasting disease (CWD), a transmissible spongiform encephalopathy of cervids, remains prevalent in North American elk, white-tailed deer and mule deer.

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 ...

Epidemiology of the lymphatic-dwelling filarioid nematode Rumenfilaria andersoni in free-ranging moose (Alces alces) and other cervids of North America [PDF]

, 2016
Background: Moose (Alces alces) are a culturally and economically valued species in Minnesota, where the northeast population has decreased by 60 % since 2006.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Rangifer population ecology: a Scandinavian perspective

Rangifer, 1997
Population ecology is concerned with measuring changes in population size and composition, and identifying the causes of these fluctuations. Important driving variables include animal body size and growth rate, and their relationship to reproduction and ...

Effects of mining on reindeer/caribou populations and indigenous livelihoods : community-based monitoring by Sami reindeer herders in Sweden and First Nations in Canada [PDF]

, 2014
This paper explores the effects of human disturbances associated with mine development in the Arctic on habitat and populations of reindeer/caribou (both Rangifer tarandus), and implications for reindeer husbandry and caribou hunting of indigenous Sami ...

Chronic Wasting Disease management responses in North America: A public policy analysis

Wildlife Society Bulletin, EarlyView.
In this study we use the Multiple Streams Framework from public policy theory to assess the responses of wildlife management agencies in states and provinces with CWD‐positive cases in the United States and Canada to alleviate public concerns and manage the spread of this disease.
