Although a natural effect, climate change has significance to impact invasive species and has many variables that make it fit to be its own category. The five main potential consequences of climate change that affect invasive species are the alteration transportation and introduction, climatic constraints, distributions of existing invasive species, impact of existing invasive species, and the effectiveness of management strategies (Hellmann et al., 2008). Each consequence isn’t the only one that can occur. Many consequences can occur from a climate change. Species have the ability to attach to human transportation vessels and spread. It weather impacts travel it would impact the species spread. Sometimes the introduction can happen with intention as well. Either way, the impact of the transportation can affect the movement of the invasive species. The climate change could affect invasive species by increasing or decreasing their chance of establishment, or drives native species away increasing their competitiveness. The climate change can impact the distribution of the invasive species by influencing spreading to new areas. The impact on current species after climate change is the typical concept of how species invade and break down ecosystems in many aspects. Each of these consequences can be beneficial to the planning of management solutions. It provides strength to the concept of preservation management and that the support for each of the consequences is vast. Unfortunately, since there is a mix of variables the concepts are still in need of more investigation before management plans or otherwise could be taken from it. In time, the some variables could be more controlled to allow for more narrow results.

Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
Should exotic snakes or other large reptiles be allowed as pets in Florida? Right now these escaped/released feral reptiles create an estimated $120 billion in environmental damage each year according to David Steen on Slates Animal Blog.
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.
The piece I chose to do my literary analysis on was the article, The Truth About Invasive Species, written by Alan Burdick. The article states that invasive species are all around us, but the area with the most prominent amount is the suburbs of Miami. It goes into detail about how abundant invasive species are in this area. Most people who would see a strange animal in their lawn or area would be bemused, however for the people of Southern Florida, this is a recurring scene. Burdick states that “virtually everyone in the South Florida, including Hardwick, has a neighbor with a backyard menagerie of lucrative critters on hold for resale”. Burdick describes both how an invasive species is introduced into an ecosystem, and the impact the have on other species upon their arrival.
Biodiversity is influenced by landscape fragmentation at various scales of space and time. The extinction of ecosystem types and component species may cause an increased patchiness of the landscape, resulting in lower population sizes and decreased connectivity. As a result, inhabitants may experience decreased dispersal abilities and lowered gene flows between populations.
In recent years, invasive species have become a significant concern to ecologists in many ecosystems around the globe. Specifically, the explosive of non-native Burmese pythons (Python bivittatus) in the Florida Everglades has become a major concern among ecologists and the general public alike. While it is generally accepted that this population has stemmed from the escape of these snakes from the exotic pet trade (Pyron et al., 2008), and that the snakes have been able to flourish due to the climatic similarities between South Florida and their native regions of subtropic Southeast Asia, scientists are still trying to determine exactly how the python population in the Everglades has managed to become so successful, which is being done by

When people think of invasive species, they normally do not think of the human species, but why not? There is a large debate about whether or not humans are an invasive species. Before people debate whether or not the human race is an invasive species, they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).
Invasive species, (also known as invasive alien species or simply alien species) are defined as any organism (plant, animal, pathogen, or other living thing) that is alien (non-native) to an ecosystem, which can cause adverse economical, ecological, or health effects to native species and/or humans. The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.
As the following report demonstrates, some species are adapting to climate changes while many others are not. In some cases, laboratory experiments have lead to the conclusion that certain species can or cannot adapt and evolve. This research is not sufficient to make definitive statements regarding what will happen to species if temperatures and sea levels continue to rise.
One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
In many parts of the world, ecosystems’ temperatures begin to rise and fall to extreme levels making it very difficult for animals and plants to adapt in time to survive. Climate has never been stable here on Earth. Climate is an important environmental influence on ecosystems. Climate changes the impacts of climate change, and affects ecosystems in a variety of ways. For instance, warming could force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater sys...
