Understanding spatial distributions of organisms and the consequences for conservation policy and management decisions remain important challenges. We describe a method for grouping caribou into plausible candidate Local Population Units that may better approximate geographic closure than the existing LPUs.

We aimed at assessing seasonal movement behaviours, including migratory, resident, dispersing, and nomadic, for caribou belonging to the Barren-ground and Woodland subspecies and ecotypes. Our unexpected findings of marked seasonal movement plasticity in caribou indicate that this phenomenon should be better studied to understand the resilience of this endangered species to habitat and climatic changes. Our results that a substantial proportion of individuals engaged in seasonal migration in all studied ecotypes indicate that caribou conservation plans should account for critical habitat in both summer and winter ranges.

We analyzed 20 data sets from post-calving surveys in the NWT and NU carried out between 2000 and 2015 using the Rivest estimator. We provide a set of working recommendations to optimize field sampling to ensure reliable estimates of herd size using post-calving methods.

We quantified rates of intake of digestible protein and digestible energy by tame caribou foraging in temporary enclosures in the predominant plant communities of northeastern British Columbia, Canada, during summer–autumn and compared intake rates to daily requirements for protein and energy during lactation. Our results,coupled with recent measurements of body fat of wild caribou innortheastern British Columbia, refute the hypothesis that thenutritional environment available to caribou during summer innortheastern British Columbia is adequate to fully support nutri-tional demands of lactating caribou, which has implications toproductivity of caribou populations, recovery, and conservation.
