Invasive species represent a significant threat to global biodiversity and ecosystem. The US government uses over $100 billion in the management of invasive species. The native reptiles pose a serious threat to other animals. The non-native snakes also make the mammals reduce in number because of their invasive nature. The study focuses on the invasive nature of pythons about the reduction in number of the mammals.
The brown tree snakes introduced in the mid 20th century dealt a major blow to the vertebrates in the Everglades National Park. The Burmese Pythons, which are natives of Southeast Asia, have now spread widely in the ENP. However, many pythons have been removed from the ENP. It has helped to balance the ecosystem in the park and its environs. Pythons feast on a large number of mammals and a considerable amount of the endangered species. They also help to depopulate a large number of American alligators. The available data assist in informing that the Burmese pythons have severely reduced the number of common mammals in the ENP.
Rodents like the rabbits and raccoons are the most affected species. In the peripheral locations where pythons have started increasing, the mammals have also begun reducing in number considerably. There is considerable evidence that indicates that much of the problem in the ENP is as a result of the introduction of the python. Raccoons, rabbits, and opossums are food to the pythons. They also eat the deer and bobcats.
They are the main diets given their availability. The Boid snakes disappeared in Eastern America, but some have recently reappeared. They are a migration that came in from the Hemingfordian. In Asia, the decline in mammals is due to bushmeat hunting, deforestation, and wildfire. In Australia, the reduction is partly due to the introduction of cats. However, some mammals died from road kills.
