Experimental moose reduction lowers wolf density and stops decline of endangered caribou [PDF]
PeerJ, 2017 The expansion of moose into southern British Columbia caused the decline and extirpation of woodland caribou due to their shared predators, a process commonly referred to as apparent competition.

Genomic legacy of migration in endangered caribou
PLoS Genetics, 2022 Wide-ranging animals, including migratory species, are significantly threatened by the effects of habitat fragmentation and habitat loss. In the case of terrestrial mammals, this results in nearly a quarter of species being at risk of extinction. Caribou

Seasonal movements in caribou ecotypes of Western Canada
Movement Ecology, 2022 Background Several migratory ungulates, including caribou, are dramatically declining. Caribou of the Barren-ground ecotype, which forms its own subspecies, are known to be mainly migratory.

Quantifying effects of snow depth on caribou winter range selection and movement in Arctic Alaska
Movement Ecology, 2021 Background Caribou and reindeer across the Arctic spend more than two thirds of their lives moving in snow. Yet snow-specific mechanisms driving their winter ecology and potentially influencing herd health and movement patterns are not well known ...

Fall supplemental feeding increases population growth rate of an endangered caribou herd
PeerJ, 2021 Most woodland caribou (Rangifer tarandus caribou) populations are declining primarily because of unsustainable predation resulting from habitat-mediated apparent competition.

Historical Landscape Use of Migratory Caribou: New Insights From Old Antlers
Frontiers in Ecology and Evolution, 2021 Accumulations of shed caribou antlers (Rangifer tarandus) are valuable resources for expanding the temporal scope with which we evaluate seasonal landscape use of herds.

Woodland caribou management in Alberta: historical perspectives and future opportunities
Rangifer, 2007 Woodland caribou conservation has been the topic of much debate for the past few decades. By the late 1970s there was growing concern about declining woodland caribou populations and the interaction between industrial activities and woodland caribou ...

NmeCas9 is an intrinsically high-fidelity genome-editing platform
Genome Biology, 2018 Background The development of CRISPR genome editing has transformed biomedical research. Most applications reported thus far rely upon the Cas9 protein from Streptococcus pyogenes SF370 (SpyCas9).
