Transferrin variation and evolution of Alaskan reindeer and caribou, Rangifer tarandus L.

Rangifer, 1986
Polyacrylamide gel electrophoresis was used to analyse transferrin variation in wild caribou (Rangifer tarandus granti) and domestic reindeer (R.t. tarandus) from Alaska. Eighteen alleles were detected in caribou and ten alleles were detected in reindeer.

Genetic relationships of three Yukon caribou herds determined by DNA typing

Rangifer, 2000
In this paper we examine genetic relationships of caribou (Rangifer tarandus caribou) in the Aishihik, Chisana, and Wolf Lake herds in the Yukon using DNA fingerprinting.

Predation and caribou populations

Rangifer, 1991
Predation, especially wolf (Canis lupus) predation, limits many North American caribou (Rangifer tarandus) populations below the density that food resources could sustain. The impact of predation depends on the parameters for the functional and numerical

Bacterial genomics reveal the complex epidemiology of an emerging pathogen in Arctic and boreal ungulates [PDF]

, 2016
Northern ecosystems are currently experiencing unprecedented ecological change, largely driven by a rapidly changing climate. Pathogen range expansion, and emergence and altered patterns of infectious disease, are increasingly reported in wildlife at ...

Transitions of social-ecological subsistence systems in the Arctic [PDF]

, 2017
Transitions of social-ecological systems (SES) expose governance systems to new challenges. This is particularly so in the Arctic where resource systems are increasingly subjected to global warming, industrial development and globalization which ...

Early Winter Habitat Use by Mountain Caribou in the North Cariboo and Columbia Mountains, British Columbia

Rangifer, 1996
Winter habitat use was compared between two mountain caribou (Rangifer tarandus caribou) populations in British Columbia. Regional differences were apparent during November and December.

Inferring the rules of social interaction in migrating caribou [PDF]

, 2018
Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to ...

Genetic survey of caribou populations using microsatellite DNA

Rangifer, 1996
Microsatellite loci are highly variable regions of eukaryotic DNA that consist of tandemly repeated sequences of one to six nucleotides in length. The use of microsatellites and the Polymerase Chain Reaction (PCR) are powerful tools for quantifying ...
