Evolving An Invasive Species Analysis

Invasive species make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.

It is no question that invasive species cause more damage than nourishment. They have caused harm on every continent on this planet and are a threat to their ecosystems. The key to successfully managing invasive species is to understand what they are, how they arrive here, and the damage they cause. That way we as a society can recognize the threat that they pose to our ecosystems and manage them. Step one in successfully managing invasive species is to understand what they are.

ELMIRA (WENY) - As part of New York's Invasive Species Awareness Week, the Department of Environmental Conservation and the Finger Lakes Partnership for Regional Invasive Species and Management have teamed up to educate the public on local invasive species and how to stop them from spreading.

Out of all the problems our environment faces like pollution and global warming, one of the most threatening problems is invasive species. An invasive species is an organism that is not native to an ecosystem and causes harm. They can harm the environment, economy, and even human health. When an invasive species starts to affect the economy, it becomes a bigger problem because it starts to get expensive to maintain and control.

There are invaders coming to homes all over America. They are causing damage to entire ecosystems and they can spread to new areas very rapidly if the issue is not dealt with now. These invaders that are destroying our native plants and ecosystems are known as invasive species.

An invasive species is an organism that is alien to an ecosystem. An invasive species also thrives and is able to reproduce in the new environment. The organism can range from a pathogen to an animal both of which can cause ecological or human harm

According to the Invasive Species Advisory committee, (Committe, 2006), the term, “invasive species” relates to the establishment of a non-native species in an ecosystem. Furthermore, the presence of these species is likely to cause deleterious effects to the economy, environmental or human health. However, this characterization is sometimes contradicted as some non-native species seem to be beneficial either ecologically, economically, or esthetically, in the ecosystems to which they were introduced ( Definitions Subcommittee of the Invasive Species Advisory Committee, 2006). These alien species can include various organisms such as a plants, animal, fungus or bacteria.

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

In Ohio there are several non-native plant species that are considered as invasive species. Invasive species are plants that are non-native (or alien) to an ecosystem, whose introduction causes or is likely to cause economic and environmental harm or harm to human health. Invasive plants are known to invade spaces and crowd out native species. An example of an invasive species is the Multiflora Rose ( “What is an Invasive Species”) National Invasive Species Information Center. United States Department of Agriculture.

Climate change and concomitant shifts in extreme events may favored invasive plants over to native by affecting species demographic processes, mortality, and competitive interactions between species (Hellman et al. 2008; Diez et al. 2012; Leishman and Gallagher 2015). All aspects of extreme events, however may not necessarily favor invasive over native, instead effects on native and invasive species and their responses to the events are uneven and species and context dependent (Leishman and Gallagher 2015 and references therein). For instance, salinity stress from hurricane generated storm surge and sea level rise has shown to impact native and invasive coastal plants differently (Pathikonda et al. 2009; Paudel and Battaglia 2013).

An invasive species is an organism that comes from a different area and does not belong there. These organisms often spread rapidly and take over the territory of indigenous species. An invasive species can be introduced to the non-native environment unintentionally through international trade and travel, or intentionally as pets, ornamental plants, and environmental studies.

This article is introducing the reader to invasive alien species as the second largest threat to ecosystem’s biological resources with its effect through data that is recorded in different time and place. It gives us the outline of why and how to range the 100th of the world’s worst invasive alien species based on their serious impact and their score of spread. This is a good source because the author did a lot of research on this area and uses the nearest 10 years data for supporting the thesis. The article is also showing the reason why the invasive species can be considering as the threat to the environment.

The introduction of an invasive species can change the organization and functioning of the native communities through various processes such as predation, parasite transfer or competitive exclusion. The two main explanations why some exotic species become invasive species are superiority in competition and the opportunistic use of ecological niches generated by human activities. (Nishizawa). Invasive species contributed to the decline of 42% of the threatened and endangered species in the United States. Not only that, invasive species’ impact is about five percent of the world’s economy. (Pimentel et al. 2005). For example, we were conducting an experiment with an invasive species called Elephant Ears. Elephant ears can be invasive

Dr. John visited Norfolk State University on behalf of the Department of Ecology at the University of Georgia. He came to share information about invasive plants and the ecological research that he and others have conducted on it; his talk was entitled “Computational Botany for Invasive Species Decision Support, Risk Analysis, and Policy.”

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.
