Summary

During 1987-1991, 29 to 45 radio-collared caribou cows were monitored daily during calving each year and their calves were radio-collared (n = 147 calves) to investigate calf production and survival. We determined characteristics of wolf predation on caribou calves and, utilizing information from a companion wolf study, evaluated the role of spacing by caribou cows in minimizing wolf predation on neonates (calves < 15 days old) during a period when wolf abundance doubled. On average, 49% of the neonates died, ranging from 30% in 1987 to 71% in 1991. Overall, wolves killed 22% of the neonates produced and were the most important mortality agent. Wolves preyed on calves primarily during six days following the peak of calving and usually [...]
