Growth rates and morphological measurements of Porcupine caribou calves

open access: yesRangifer, 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.

Quantifying harvest of barren‐ground caribou off a winter road in the Northwest Territories – An Indigenous Guardian‐led initiative

open access: yesThe Journal of Wildlife Management, EarlyView.
The North Slave Métis Alliance's Indigenous Guardianship Program conducted on‐the‐ground patrols monitoring caribou interactions with the Tibbitt to Contwoyto Winter road and quantify caribou harvest. Quantifying the impacts of winter roads on barren‐ground caribou herds supports community members’ commitment to safeguarding their traditional territory

FennoTraits: dataset of plant functional traits and community composition in northern European flora

open access: yesNordic Journal of Botany, EarlyView.
We present here FennoTraits, a dataset of plant functional trait and community composition data collected from Fennoscandia across northern Finland, Norway, and Sweden in 2016–2025. This dataset has 42 049 abundance estimations and 155 794 site‐level functional trait observations from 10 traits representing 373 vascular plant species collected from ...

The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

History, Status, and Taxonomic Identity of Caribou (Rangifer tarandus) in Northwest Greenland [PDF]

open access: yes, 1984
Historical references indicate that caribou (Rangifer tarandus L.) numbers drastically declined throughout the Thule District during the early part of this century, and that the primary causes were: (1) the influx of polar explorers and their ...

Snowmelt Onset and Caribou (Rangifer tarandus) Spring Migration

open access: yesRemote Sensing
Caribou (Rangifer tarandus) undergo exceptionally large, annual synchronized migrations of thousands of kilometers, triggered by their shared environmental stimuli. The proximate triggers of those migrations remain mysterious, though snow characteristics play an important role due to their influence on the mechanics of locomotion.

Ungulate substrate use in fauna passages

open access: yesWildlife 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 Ecology of Caribou in British Columbia

open access: yesRangifer, 1996
The abundance and geographic range of woodland caribou (Rangifer tarandus caribou) decreased in many areas of British Columbia during the 1900's. Recent studies have found that predation during the summer is the major cause of mortality and current ...

Forest and fire drive moose (deníe) detections near their northern range limit

open access: yesWildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

Wolf predation in the Burwash caribou herd, southwest Yukon

open access: yesRangifer, 1986
The role of wolf predation as a proximate mortality factor influencing caribou herd growth was assessed in the Burwash herd (400 animals) in the southwest Yukon between 1980 - 1982.
