Ungulate substrate use in fauna passages
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Micro‐habitat selection by boreal woodland caribou improves access to food
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 ...

Elaphostrongylus spp. from Scandinavian cervidae - a scanning electron microscope study (SEM)
Nematodes of the genus Elaphostrongylus collected from moose (Alces alces L.), reindeer (Rangifer tarandus tarandus L.), and red deer (Cervus elaphus L.), respectively, were studied by means of scanning electron microscopy.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
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 ...

Summer feeding behaviour of reindeer [PDF]
Reindeer (Rangifer tarandus L.) plays an important role ecologically, economically, as well as culturally in northern Fennoscandia, where reindeer husbandry traditionally has considered winter to be the bottleneck for reindeer.

Experimental oral transmission of chronic wasting disease to reindeer (Rangifer tarandus tarandus). [PDF]
Chronic wasting disease (CWD), a transmissible spongiform encephalopathy of cervids, remains prevalent in North American elk, white-tailed deer and mule deer.

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

Insect avoidance may override human disturbances in reindeer habitat selection
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 ...

Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,
