Reduction in numbers of game should have boded ill for their survival in later times. A worsening of the plight of deer was to be expected as settlers encroached on the land, logging, burning, and clearing, eventually replacing a wilderness landscape with roads, cities, towns, and factories. No doubt the numbers of deer declined still further. Recall
the fate of the Columbian white-tailed deer
, now in a protected status. But for the black-tailed deer, human pressure has had just the opposite effect. Wildlife zoologist Helmut Buechner(1953), in reviewing the nature of biotic changes in Washington through recorded time, says that "since the early 1940s, the state has had more deer than at any other time in its history, the winter population fluctuating around approximately 320,000 deer(mule and black-tailed deer), which will yield about 65,000 of either sex and any age annually for an
indefinite period
." [br] Which of the following statements about deer populations is supported by the information in paragraph 4?
选项
A、Deer populations reached their highest point during the 1940s and then began to decline.
B、The activities of settlers contributed in unexpected ways to the growth of some deer populations in later times.
C、The clearing of wilderness land for construction caused biotic changes from which the black-tailed deer population has never recovered.
D、Since the 1940s the winter populations of deer have fluctuated more than the summer populations have.
