Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
Invasive species Pythons population is rapidly growing in Florida causing corruption in florida with the animals and their habitats. Invasive species in the United states is a big problem especially in the everglades in Florida and other places in the south. The invasive species are from all over the word and they are all different types of animals. Most invasive animals in the everglades eating other bait fish which are other animals prey and possibly eating other predators. I know at my house we have some overpopulated animals but if they were to be eaten by an opposing animal plants would overpopulate my woods at my house.
Eurasian Watermilfoil Invasive species are becoming a big problem in today’s society. They are not native to the local habitat. A lot of times, invasive species are extraordinarily good at adapting to the environment. However, they can block out and do harm to other native organisms.
When a certain species is removed from their ecosystem, it can have effects on their prey and their predators. Their prey’s population would increase, and their predator’s population would decrease due to their being nothing for it to eat.
Ecosystems are composed of a predator prey relationships that help keep balance within it. Without predators the prey population would rise to a point where the ecosystem does not have enough resources to support them, causing starvation and eventually death within the population. The population would get to a point where there is
They’ve crippled the Everglades’ populations of opossums, rabbits, bobcats and foxes, thus dominating the food web to such a degree that there’s not much of a web anymore. Invasive pythons aren’t the only non-native species that threaten the Everglades ecosystem. There are invasive plants too, hurting the balance of the Everglades, not only choking out native species (some vine-like plants actually grow over original trees and plants), but growing so thick that they block water flow and movement of
Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats.
A massive fish came soaring out of the water and crashed into your jaw as you were powerboating by the Great Lakes. Was it a shark, or the lochness monster? Nope, it was an one-hundred pound Asian Carp. Asian Carp are examples of Invasive species. Exotic invasive species share many commonalities amongst each other in their extreme ability to arrive, survive, and thrive.
Firstly, they will kill fish which is quite in opposition of attraction for tourists. Also, as they get food, they force beloved species to decline into near extinction such as the trout. A third example is that when a sea lamprey kills its prey, they take away that fish from commercial use. Sea Lamprey has no sustenance for marine
THE ZEBRA MUSSEL INCIDENT The Zebra Mussel Incident Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
Isaiah Edgerton Florida's Everglades is a wetland ecosystem that is home the many animal and plants. Florida's Everglades native species are being threatened by invasive species such as pythons and there offspring who have been released in to the wild by pet owners. Before people knew the benefits of Florida's Everglades people wanted to drained it to get rid of the disease caring bugs, residential and industrial development, farming land, and dumping which caused pollution. Now people know the good o Florida's Everglades out ways the bad as it can buffer storms, provide hunting and fishing, and provides jobs and attractions.
The other predators are introduced animals. The first one was the Dingo. This was introduced as a domestic Dog several thousand years ago; it became feral. More recently, the Europeans have introduced Foxes for recreational hunting. Cats are also a problem.
An example of a species that has undergone a change due to an environmental alteration, is the Brush Tail Possum (Trichosurus vulpecular). The Brush Tail Possum is native to Australia and was introduced into New Zealand in the 19th century for the purpose of gathering fur for the fur industry. However, the species thrived in this environment and is now considered an agricultural pest. The possum can also carry a disease called
There cannot be an ecosystem or environment without some form of diversity. Forests that dominantly had only one type of tree are hugely in danger of destruction. This destruction will not come from human hands, but from nature itself, as diseases can easily devastate the environment. With diversity, the system can remain healthy for if one type of plant is wiped out, there are many others to take its place and fill the gap.
