Transcript of Invasive Species Burmese Python

Invasive Species: Burmese Python Biotic Factors: Habitat: Affect on Other Species Population: Burmese pythons are native to the jungles, grassy marshes, and tropic/subtropic areas of Southeast Asia, but they have also been spotted in Florida's Everglades National Park. Being one of the largest snakes in the world, the Burmese Python has a large appetite. The snake has been found in the Florida Everglades, and could potentially have a catastrophic effect on the ecosystem. Endangered/threatened species due to the Burmese Python: Foxes and rabbits have disappeared entirely, while sightings of raccoons, possums, and white-tailed deer are decreasing dramatically. But they've also been known to feed on birds. Abiotic Factors: The trees and grass affect the environment of this python. If they weren't there, the snake would have no home or no camouflage while it was stalking it's prey. The animals it feeds on are biotic factors because they are living factors, and without a food supply, the snake would starve and die. The temperature and global warming affect the python, and this is why the snake is found in areas of Florida and Southeast Asia, because those places are warmer and have a lot of water, grass, and dense vegetation to make homes in. General Ideas of Ecology: Levels of Organization: * Individual - one of a certain species
* Population - members of the same species that live in the same area
* Community - all of the populations in a particular area
* Ecosystem - includes all living things and their physical environments within a particular area
* Biosphere - includes all parts of Earth that host life, with all of it's organisms and environments Ecology: study of how organisms interact with each other and their environments

Species: group of individuals that interbreed and produce fertile offspring (ex. humans interbreed & reproduce offspring)

Biotic Factors: parts of an ecosystem that are living or used to be living (ex. a tree that has fallen down and rotting)

Abiotic Factors: parts of an ecosystem that have never been living (ex. temperature, wind, or pH)

Habitat: the specific environment in which an organism lives (ex. golden toads live in a cloud forest.)

Resource: anything an organism needs (ex. nutrients, shelter, and mates)

Population Size: number of individual organisms present in a population at one time (ex. increasing/decling pop.)

Population Density: number of individuals within a population per unit area (ex. huge flocks of passenger pigeons)

Population Distribution: how organisms are arranged within the area (ex. random, uniform, clumped)

Age Structure: describes relative numbers of organisms of each age within a population (ex. pop. with different ages) Reproduction Pattern Patterns of Immigration/Emigration/Migration: Population Size It is guessed that since the 1990s, the population of the snake has grown to a large number of 30,000 in the Florida Everglades. It is also estimated that the current population could grow to 7 billion by 2032. Burmese Pythons are native to Southeast Asia, but they were brought to Florida as exotic pets. There is a story that states the first "pet" python was released or escaped into the Everglades during Hurricane Andrew in 1992. Since the Everglades provides a lush, tropic environment with no natural enemy of the snake, it was perfect breeding ground. Cooler temperatures and wet climate are more suitable for the snakes. Breeding usually occurs between late October and early March. After the snakes reach maturity, they will reproduce. After copulation, the female will take up to a month to ovulate and will lay eggs after a pre-lay shred. She will then incubate the good eggs and push infertile eggs out of her coils. She will lay 20-80+ eggs and they will hatch in about 55 to 75 days. Producer or Consumer? Consumer: the Burmese Python is a carnivore because it kills and eats other animals. Niche of the Burmese Python: This snake needs a permanent water source and likes grassy areas. They are one of the largest snakes in the world, so they need a variety of animals for their food source, like white-tailed dear, rabbits, and other repitiles. This snake originally came from a grassland and wooded biome. They invaded another grassland in Southern Florida when they were "let go" by their owners, or escaped into the wild. There are many other species besides the Burmese Python in the Everglades. Many species of birds, turtles, deer, raccoons, oaks, bobcats, hawks, crocidiles, and alligators have made their home in the Everglades. This area is very diverse. Before the Burmese Python was introduced to the area, the ecological community was full of other animals, but as the population of the python grows, the other populations are decreasing. Stopping the Python Invasion The Python Patrol was launched by The Nature Conservancy in the Florida Keys was launched in 2008 after Burmese Pythons were found eating rare Key Largo woodrats. If a citizen sees a snake, they are to call it in to wildlife officials. More than 200 python capture responders have been trained to catch these dangerous animals.
