Caribou of the Central Arctic Region of Alaska in relation to adjacent caribou herds
There was an unusual increase in numbers of caribou (Rangifer tarandus granti) in the Central Arctic region of Alaska from 1981 to 1985. In fall and winter numbers were up to five times greater than at the onset of calving in June.

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...

Population genetics of woodland caribou (Rangifer tarandus caribou) on the island of Newfoundland
The purpose of this study was to characterize the genetic variation and genetic structure of caribou herds on the island of Newfoundland. A 2223 bp sequence of mitochondrial DNA from the Control Region and the cytochrome b gene was sequenced for 233 ...

Arctic ungulates at the northern edge of terrestrial life
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.

Two species of protostrongylid nematodes with dorsal-spined, first-stage larvae, are present in caribou and moose of Newfoundland. Elaphostrongyius rangiferi Mitskevich, 1958, a parasite introduced from Scandinavia, causes periodic epizootics of a severe neurological disease in caribou. Sick animals exhibiting signs of cerebrospinal elaphostrongylosis (

This review evaluates the clinical potential and limitations of intranasal (IN) drug administration in veterinary anaesthesia and emergency care. IN delivery can provide clinically relevant sedation, analgesia and drug reversal, but its success is not universally reliable and is strongly influenced by species‐specific anatomy, formulation ...

Using information theory to select spatial scales for species–habitat responses with camera traps
Abstract Widespread anthropogenic landscape change, particularly from energy development, has fundamentally reshaped ecosystems, and understanding species responses remains a central ecological challenge. Remote camera traps are widely used to estimate mammal abundance and distribution, but inferring species–habitat relationships from these data is ...

Wetland habitat selection by woodland caribou as characterized using the Alberta Wetland Inventory
We examined habitat selection by woodland caribou (Rangifer tarandus caribou) in northwestern Alberta based on a wetland classification system developed for the Alberta Vegetation Inventory. Our two objectives were to describe caribou habitat use, and to
