Climatic Conditions as They Affect Food Habits Temperature, precipitation, and snowfall arc yearly variables which greatly influence the diet and welfare of the An'v. During mild winters, loss of deer is negligible and winter survival is reflected in both a high Eawn-aduH ratio and an increase in numbers of animals migrating into Oregon in the spring. Certainly, maximum carrying capacity is a dynamic factor largely determined by yearly variations in climatic conditions. This weather phenomenon not only directly affects the avail- ability of food, especially the animal herbaceous component of the range, bu1 also exerts physical influence on the deer themselves. A breakdown of Table :{ into the individual winters represented in the study presents a most interesting picture.
