Summary Introduction
Introduction: Endangered species are the species that are under the risk of extinction in the near future. In 1973, the Endangered Species Act (ESA) was enacted to protect the endangered species. Under this act, certain criteria were established to classify the endangered species, which enabled the federal government to take responsibility to protect these species. Examples for endangered species include the gray wolf, Florida panther, grizzly bear, bald eagle, and so on.

- The Burmese Python, an invasive species, has been introduced to the Florida Everglades, largely through release by owners who acquired the snakes from exotic pet traders. Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades? A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades. B. Since the python population is growing, it will eventually become a native species and will increase biodiversity. C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered. D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.arrow_forwardThe abundance of a species population, within its habitat, is called?arrow_forwardWhat are the implications of the "bottleneck effect" for wildlife managers who try to help endangered species, such as the whooping crane, recover from near extinction?arrow_forward
