The number of white-tailed deer in certain areas of Long Island, NY has increased significantly. Homeowners and farmers have put up tall fencing to protect their gardens and crops from the deer. One reason why the white tailed-deer might have increased significantly in certain areas of Long Island is * 3 points A the lack of natural predators B an increase in deer pathogens C a shortage of biotic resources needed by the deer D that carrying capacity has no effect on deer populations

A. the lack of natural predators

Explanation:

The white-tailed deer inhabits a wide variety of environments. The species characterizes by its adaptation to different conditions, especially in contact with human beings and their activities.

Due to human action and the change in the environment, populations of white-tailed deer have expanded to Canada. Due to its adaptability capability, the deer have reproduced more than expected in some regions, up to the point of being detrimental for people.

In fact, In the United States and Canada, the overabundance of the species has brought consequences to people, such as plagues, accidents, diseases, material loss, among others.

Human action modified the deer habitat, but other species were affected too. It is the case of wolves or pumas, natural predators of the white-tailed deer. The natural habitats of these species have been destroyed, and they have been summited to extensive hunting for years. Habitat reduction and hunting drove these species to disappear.

One of the principal reasons for deer overpopulation is the absence of predators. Under natural conditions, pumas and wolves keep deer population growth under control. However, once these species were eliminated, the white-tailed deer was not affected by predation pressures anymore

The absence of natural predators and the adaptation capability to different environments and border effects made it possible for the white-tailed deer population to overgrowth.
