摘要

The report on forest habitats and the nutritional ecology of Sitka black-tailed deer conducted during 1981 through 1986 is reviewed and synthesized. The research approach was based on the assumption that foraging efficiency is the best single measure of habitat quality for an individual deer. Overstory-understory relationships and the influence of forest overstory on snow depth and density, forage availability and forage quality were studied in the western hem-lock-Sitka spruce forests of southeastern Alaska. The effects of forests management were analyzed. Research on the nutritional ecology of deer emphasized environmental influence forage quality, energy and nutrient intake by foraging deer, energy expenditure by deer, foraging efficiency, and nutritional determinants of carrying capacity.
