Arctic ungulates at the northern edge of terrestrial life
Rangifer, 1996 The two ungulate species that occur in the High Arctic, Rangifer tarandus and Ovibos moschatus, exhibit considerable adaptive plasticity in response to habitat variability throughout their circumpolar distribution. R.

Predation on Caribou (Rangifer tarandus) by Wolverines (Gulo gulo) after long pursuits
Canadian field-naturalist, 2019 Ungulates are an important source of food for Wolverines (Gulo gulo), especially in winter when scavenging on carcasses is a primary means of obtaining food. However, Wolverines are also known to prey on ungulates.

Hunting regulations and movements of alpine reindeer
Wildlife Biology, EarlyView.Most ungulate populations are regulated by hunting, and harvest rate is regulated through quotas and hunting season duration. Hunting is well known to affect behaviour of ungulates, but how annual variation in quotas and hunting season duration affects individual behaviour remains uncertain.

Conjunctival squamous cell carcinoma in a reindeer (Rangifer tarandus tarandus)
Veterinary Ophthalmology, 2012 AbstractAn 8‐year‐old female adult reindeer (Rangifer tarandus tarandus) was referred to the Veterinary Hospital of Madrid for evaluation of a conjunctival mass on the left eye which had been present for about 2 months. A surgical excision was performed and biopsy material submitted for light microscopic evaluation which confirmed the diagnosis of ...

Ungulate substrate use in fauna passages
Wildlife Biology, EarlyView.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.

Population dynamics of wild reindeer (Rangifer tarandus L.) on the Taimyr Peninsula: A simulation model [PDF]
, 2013 A simulation model, based on original and published data, has been developed to determine the period and amplitude of natural population cycles of wild reindeer on the Taimyr Peninsula and reveal the role of hunting in these cycles.

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 ...

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 ...

Growth rates and morphological measurements of Porcupine caribou calves
Rangifer, 1989 Body weights, leg lengths, and surface area were monitored for bottle-raised barren-ground caribou calves (Rangifer tarandus granti) from the Porcupine herd up to 1 year of age.
