Essay On Invasive Species

A group of researchers collected data to support the theory that the overpopulation of snakes is killing off the mammal population. Ashley Townsend, National Geographic writes, “the python population has continued to grow at a remarkable rate and has caused great distress to the park 's ecosystem.” For this study, the researchers at the South Florida Water Management District recorded the rates of live and dead mammals during a nocturnal road survey and compared it to the 1996-1997 road surveys. Scientists for the South Florida Management District, stated, “Researchers noted that the animals in the park were dying at a greater rate since the python population has gotten so enormous.”

Burmese pythons The presence of the Burmese pythons are making people and animals suffer! They have taken over many things. For example, they have taken over the Everglades of Florida and have taken over the food chain. The pythons have taken down animals and brought the people of Florida with them.

The Burmese Python is one of many invasive species. These snakes are native the Southeast Asia. They were imported to the U.S. for pet trade. However, people who own these snakes sometimes don't realize they can grow up to 22ft and weigh up to 200 pounds. The size of these snakes prohibits them from being appropriate pets. As a result these animals are released into the wild. Not only does this affect the ecosystem, but it also affects the mammal and bird populations. In the

I think that these pythons are causing many problems and if we do not remove them from the ecosystem soon, they might cause permanent damage. I think that if we need to step in to stop this problem, it has grown far too big for comfort. These snakes are diminishing populations by the minute. If we wait any longer, the entire Florida ecosystem may no longer

As previously stated, overpopulation is a big problem too. With so many of them in the Everglades, their food sources numbers are declining. But this is the outcome of previous python owners being “downright stupid” and purchasing a pet snake “without researching anything” about the python. (EcoEchoes, page 47, Paragraph 3) The outcome usually ends with the owners letting them go into the wild. Resulting in its overpopulation in the Everglades.

Biodiversity is something the snakes are also messing with. The definition is " Having many different kinds of plants and animals means that species have different choices for survival" as say in the article Are the Everglades Forever?. So by snakes eating most of the animals , its not giving an opportunity to the other animals

Say a frog eats a caterpillar, then a snake eats the frog, then finally a owl eats the snake. This is just a simple food chain but something called biodiversity, which means that’s there is a variety of things a that one animal can eat. An owl cant only eat a snake it could eat the frog or something smaller like a worm. This keeps form one species dying out completely, which would cause multiple species to die out. When someone releases a pet into the wild they are causing a disturbance into the wild habitat. When a python is released into a place full of crocodiles these two will start competing for food which would cause all of the lower species to start lowing in numbers faster until they become extinct which would then make the snakes and the crocodile die off too. If this keeps on happening the eventually every animal would die off!

One environmental issue that the great lakes watershed has been exposed to is invasive species. An invasive species is any organism that is foreign to an ecosystem and causes harm (United States Environmental Protection Agency, 2016). In ordered to be classified as foreign they do not have to be from a different country but they just must be a non-native to an established ecosystem. Some of the species travel at their own will but they primarily spread through human activities unintentionally. As we import and export goods, or travel, some uninvited species may ride along and travel to new places. Organisms can be stowed away in ships or products like wood. Some ornamental plants may

Pythons, wild pigs, and red foxes are all very scary to other animals and to humans. Throughout the years many people in the U.S have brought different invasive animals that can hurt the ecosystem they live in and can cause a serious problem with endangered species. Invasive species came into the U.S’s eyes earlier in the day and the problem could either be getting better or worse. These animals are all over our U.S including Texas and Florida etc. Invasive species are a problem and there are many creative ways the problem is being addressed.

There are many different species of snakes in the U.S that are all important to the ecosystem, but there are some that don’t belong here and they are now considered invasive species. I believe that the Burmese python has had a massive impact to the Everglades National Park located in Florida.

A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. Such an organism plays a role in its ecosystem that is analogous to the role of a keystone in an arch. While the keystone feels the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. It has become a very popular concept in conservation biology.

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

Exotic animals can easily become endangered animals. According to current estimates, a third of the world’s amphibians, one in eight birds, and a quarter of all mammals are endangered. (“Endangered Species”). On average, there are twenty-three states in the United States of America alone that allow you to legally own an exotic animal, and twelve of those you do not even need a permit to acquire them (Loria). This increases the chance of fatality, malnourishment, being endangered, extinction and other issues. Exotic animals being kept can also endanger humans while being in harm's way themselves. Examples of some popular exotic animals some people might not consider exotic are snakes, birds, monkeys, big cats, and turtles. Turtles are the most endangered in the vertebrate groups due to the pet trade. This is because once you get a turtle, you cannot release it again or else it will not survive. Second, big cats are extremely popular in the US. There are around 10,000 tigers being kept as pets. This means there are more tigers kept as pets than in the wild. Statistically, since 1990 there have been 21 human deaths, 246 maulings, and 143 wild-cat deaths in captivity. Next, monkeys are also incredibly popular. Monkeys can carry various diseases such as Herpes B-Virus, Monkeypox, Ebola, and many more. Owning a monkey is bad for the monkey and for the owner. Additionally, there are over 150,000 parrots smuggled into the U.S. every year. Birds are meant to fly and be free, not to have their wings clipped and be confined into a tiny space. They have lost their whole life, and freedom so they can be called “pretty bird” and fed little pellets. Lastly, are the snakes. Snakes are everywhere around the world, ranging in color, shape, size, and species. In the last decade, more than 12 people have been killed from boa constrictor incidents, and with even more injuries. Snakes are also very dangerous to humans. Not only do a lot of

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
