Highlights

 - Boreal caribou persistence has been affected by landscape disturbance and subsequent apparent competition.
- Climatic conditions also affect caribou via energy gains and losses and indirectly through climate-predator interactions.
- NASA’s MERRA climate dataset was paired with data from long-term monitoring of caribou using animal telemetry.
- Caribou survival was determined using known-fate models in program MARK.
- An information-theoretic approach was used to evaluate multiple models of adult female caribou survival.
- Patterns of annual and within-year survival varied among populations.
- Snow precipitation, fractional snow cover and freezing rain influenced survival of adult female boreal caribou.
