Predation and caribou populations

open access: yesRangifer, 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

Ungulate occurrence in forest harvest blocks is influenced by forage availability, surrounding habitat and silviculture practices

open access: yesEcological Solutions and Evidence, 2023
Forest harvesting causes habitat loss and alteration and can change predator–prey dynamics. In Canada, forest harvesting has shifted the distribution and abundance of ungulates (deer, elk and moose) that prefer early seral forest, resulting in ...

Predator–prey co‐occurrence in harvest blocks: Implications for caribou and forestry

open access: yesConservation Science and Practice, 2022
Forest harvesting alters habitat, impacts wildlife, and disrupts ecosystem function. Across the boreal forest of Canada, forest harvesting affects ungulate prey species and their predators, with cascading impacts on other species, including threatened ...

Combining stable isotopes, morphological, and molecular analyses to reconstruct the diet of free‐ranging consumers

open access: yesEcology and Evolution, 2020
Accurate estimates of animal diet composition are essential to untangle complex interactions in food webs. Biomarkers and molecular tools are increasingly used to estimate diet, sometimes alongside traditional dietary tracing methods.

Caribou and Man

open access: yesRangifer, 2003
From April 23 to 27, 2001, more than 230 caribou experts migrated to the 9th North American Caribou Workshop, held at the tree-line in the Inuit town of Kuujjuaq, Nunavik, Québec. This community of about 1800 people near Ungava Bay was chosen over larger cities in southern Québec following a survey of potential workshop ...

Genomic population structure and inbreeding history of Lake Superior caribou

open access: yesEcology and Evolution, 2023
Caribou (Rangifer tarandus) have experienced dramatic declines in both range and population size across Canada over the past century. Boreal caribou (R. t. caribou), 1 of the 12 Designatable Units, has lost approximately half of its historic range in the

Woodland caribou management in Alberta: historical perspectives and future opportunities

open access: yesRangifer, 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

open access: yesGenome 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).
