Insights for Caribou/Reindeer Management Using Optimal Foraging Theory
"Optimal foraging theory is useful to wildlife managers, because it helps explain the nutritional value of different habitats for wildlife species. Based upon nutritional value, the use of different habitats can be predicted, including how factors such as insect harassment, predation and migrat...
