harder the winter bigger the deer,southern states do not see much of a winter,and all them crops up north and they have flat land to,bucks get big up there,around here in tennessee we have hills and bucks got to burn fat to go over these babys. farther south you go smaller deer you get like florida ,it stays warm down there ,so smaller the deer.up their in canada,realy big bucks,extreme winters.bigger the bucks are goin to be.northeast like newyork,they have hills to,and not much of wide open area like nebraska has.but some deer up in northeast can look like deer in the midwest.depends on food source,terrain,whether.

Actually the whole matter of mammals and size in relation to the equator has to do with body surface area ratios. The larger the body surface area becomes the lower the ratio is in proportion to mass. The lower the ratio the easier to keep the body mass warm............dabow

Have you ever noticed that some deer from different areas have different shaped heads? Some areas have narrow snouts and some are short and stubby.
