Preserving the Evolution of Habitats by Managing Barriers
Through time and great experimentation, today’s modern scientific researchers have evolved themselves to great lengths in understanding the connections and misconceptions behind the ever-changing biological environments of certain endangered, threatened and invasive species. We will delve into the ecosystems, environments, and abrasive animalistic psychologies of one species representing each of these three categories. Representing the endangered species is the Sumatran Tiger; the threatened - Canadian Lynx; and the invasive - Asian Carp. Although to compare these three species and their environments might be a decent approach to solving the escalating problem of inadvertency and either non-dominate or over-domineering aspects of their complacency within their ecosystem, the more compelling idea with which to wrestle, is how modern day ecologists and biologists can manufacture ways to resolve these issues. The key to resolution in the overpopulation of invasive species, and the threatening and endangered aspects of others is evolution, and the species to continue to evolve into a prospective and thriving species, without of course, becoming invasive. These three chosen species have evolved to either come to their fate of doom, and their lack of ability to survive, or they have come to their ultimately reversed fate by drowning their ecosystems with over domineering traits, which inevitably will cause the fate of their doom, as well.
Diagnosis of the species physicality and special biological qualities, and comparing these to their ecosystems, naturally, will give us a high insight on the problem causing their demise. The Sumatran Tiger and actually all tigers, “Tigris,”...

Did you know that you happen to be surrounded by invasive species? These species are animals that come into areas they do not belong in. The articles, “Invaders among Us,” and “Invader Alert,” show this. They harm the environment, cost tons of money in damage and extermination, and they have to be prevented.
Now, just a couple of years later, the Colorado Division of Wildlife is planning to release over 180 more lynx into the Colorado wilderness within the next five years. However, out of nearly 100 Canadian Lynx that have already been released so far, about half of them have died and none of them have reproduced. With the type of results that the process has received so far, the agencies involved in the reintroduction process should stop reintroducing the lynx into Colorado. Instead, they should try to find a way different way that will get results that save the species. The government agencies that are involved in reintroducing the lynx argue that it should be done in order to save an endangered species. In this argument they bring out three strong points for trying to save the lynx: every animal should have the opportunity to exist, many people feel happy when they see the animals they share the land with and all living things are part of a complex ecosystem ("Wildlife Commission . . ."). However, they aren't sure how to reintroduce the lynx so that they don't all die.
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.
...rupt native species and ecosystem hence making the restoration of both evolutional and ecological potential almost impossible. Whereas Donlan (2005) concluded that re-wilding North American is the best conservation strategy to the African and Asian threatened megafauna, meanwhile re-wilding will restores the evolutionary and ecological potentials in the process. In my point of view, Pleistocene re-wilding must not be implemented simply because the introduced species might fail to adapt to the new environment. High costs and disease outbreak are another challenge that can’t be ignored.

Through millions of years of evolution, well-balanced habitats have co-evolved to provide for the wide variety of species and their needs. Trees have adapted to weeds, weeds have adapted to the predation from herbivores, and so on up the food chain. Similar scenarios are seen throughout the world. Through the process of natural selection, specific species or broad species families will go extinct. However, these occurrences have largely been due to the natural flow and evolution of time. It wasn’t until recently that dominant species, such as humans, have taken the course of nature into their own hands.

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.
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...
