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 ...
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.
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.
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.
Many species are affected by poaching, including illegal hunting, fishing and capturing of wild animals, and, in a recent usage, the illegal harvesting of wild plant species. [ 1 ] [ 2 ] [ 3 ] The article provides an overview of species currently endangered or impaired by poaching in the Americas, sub-Saharan Africa, and South-East Asia .
Population control is the practice of artificially maintaining the size of any population.It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology.
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

The hunting of an already limited species can easily lead to its extinction, as with the bluebuck whose range was confined to 1,700 square miles (4,400 km 2) and which was hunted into extinction soon after discovery by European settlers. [12]
