In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
The species’ rebound was so successful that the state instituted a hunting season in 2008, which accounts for the yearly harvest of 300-400 gators across the state. DNR estimates there are about ...
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.

This hunting has imposed an artificial selection pressure on the organisms being hunted. [11] The selection pressure on varmints is probably for younger reproduction ages and earlier maturity. Varmint hunting is also potentially selecting for behavioral changes that are desired, animals avoiding human populated areas, crops, and livestock.
