Write An Essay On Invasive Species

With the environment, as one of the most commonly discussed topics today, invasive species are often included in these discussions. However, many seem to participate in these conversations with limited background on the topic. It seems that non-native species are unfairly given the title of ‘invasive’ for a variety of reasons which I plan to explore. As a starting point, it is important to understand the various titles that are allocated to non-native species that have been introduced into a new ecosystem. Under the umbrella of non-native species, there are multiple classifications given to wildlife found in a region different from where the species originates. The broadest of these classifications is non-native or exotic. Non-native is very much a cut and dried description; the species is found in an area that it is not native to. Beyond non-native is established exotic. A species can be distinguished as established exotic if it is first considered a non-native species, then can establish a breeding population. In short, this means that the species must not only be new to an environment, but can then survive and succeed as a species in that environment. Last, there is invasive. To be considered an invasive species, the species must fit three criteria: one, the species is not native to the environment it is found in. Two, the species has been able to reproduce and has created a viable breeding population in the new environment. And finally, the species has begun to cause

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

There are currently 6,500+ invasive species that have been found on park lands, 70 percent of those invasive species that were documented are plants (“Invasive Species…..What are they and why are they a problem?” 1). Something that is even more worrying is that five percent of park lands are dominated by said invasive plant species (“Invasive Species…..What are they and why are they a problem?” 1). Approximately ten percent, or 650 species, have been found in marine parks (“Invasive Species…..What are they and why are they a problem?” 1). Other than the national parks, what else is being damaged by invasive

As humans began to travel and change the landscape of the lands, the pace of invasions has increased dramatically. The word “invasive species” has a lot of negative connotations. However, invasive plants are actually like native plants, not bad when they are in their native habitat, but it is just when they are in a favorable non-native environment that causes them to become invasive. One and half million of the estimated species ten million species are identified as an invasive species. It is impossible to predict what the consequences of bringing a new

According to the Center for Invasive Species Research, “studies have also been conducted to find more resistant species of trees that could be used as replacements for susceptible tree species in urban environments.” In other words, replacing the trees that are vulnerable to the beetle’s attacks for trees that are more impervious to them can play a role in the destruction of fewer trees. According to the Journal of Integrated Pest Management, “Lure-baited traps can be used to detect Asian longhorned beetles in the field.” This shows that traps can be used to get rid of these

This invasive species was discovered in Vaughan and Toronto in 2003. Meanwhile, the beetle came to North America in the 1990’s. The beetle’s came in goods being shipped from China. They came in solid wood packaging of pallets and crates. Today, crates and pallets are being checked more cautiously so no more beetles come infect our trees. The arrival of the asian longhorned beetle has impacted us in many ways.

Although the natural ecosystem is a dynamic system that is always changing in response to environmental changes ("Invasive Alien Species in Canada." Government of Canada, Environment Canada. Government of Canada, 19 July 2013. Web. 8 July 2015. . ) . Invasive species affect the ecosystem in a negative way, both in the short term and longer term altering not only the habitat but impacting native species abundance and richness. Invasive species are successful at adapting to new environments so readily because they are generalist. Meaning that they have traits and physiological characteristics that allow them to thrive in variety of conditions, they don’t have any predators in the new environment and they are able to reproduce quickly ("Characteristics of Invasive Species." Web. 8 July 2015. .).

Earth is home to many diverse and mysterious species. These species thrive within their own ecosystem by adapting to their living habitats and food source. Though when human actions introduce new species to a foreign area where that species never lived before, this is called an exotic species (Phelan, 2013, p.640). Some of these exotic species normally do not cause a threat to the ecosystem to which it is introduced, however some do and these are called invasive species. Invasive species tend to have no predators therefore they can multiply at vastly large numbers and outcompete the native species’ food source and living space. Furthermore these native species have no prior mechanisms to defend themselves from the new invasive species therefore they can fall prey to these new invaders (Phelan, 2013, p.640).

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.

How much harm do invasive species actually create for the plants in their habitat? An invasive species is a non-native plant, fungi, or animal that takes over a foreign ecosystem by manipulating the environment and plants around them (Pysek and Chatry 2014). Invasive ecology focuses on identifying the factors underlying the infiltration of the invasive species and the affects that result. Each invasive species plays a specific role within the new community (Richardson and Pysek 2008). Not only do these invasive species cause economic harm and harm to human health, but can also affect the environment and the other plants inhabiting that ecosystem (Vila et. al 2011). Because of this, society faces a major challenge trying to manage or kill off these invasive invaders. Rapid action is the most beneficial way to manage this enemy invader. However, it is hard to recognize when the invasive species actually inhabits the land. So, other efforts must be done to eradicate the species including: digging or pulling it out, attempting to maintain the invasive species in a

Invasive species are commonly viewed as pests. Although, in some instances invasive species may provide some benefit to native species (Ashton et al., 2005). “Nonindigenous species increase the likelihood that at least some of them will harm native species” (Simberloff & Von Holle, 1999, 29). Ultimately, negative impacts to ecosystem function and structure by invasive species is far more likely to occur and should be the focus of any research in this

What is an invasive species? I believe an invasive species is an animal that has either come to a new environment on purpose or accident and caused harm by doing so. I became interested in this topic because animals are interesting to me. I did not consider any other topics. When I saw the topic I immediately went to research it. I knew bits and pieces of some stories invasive species give. New invasive species come every day because of humans and their ideas on what is best.

This article addresses the problem of invasive species, which has threatened native species all over world like the Everglades, South Africa, and the northeast region the United States (Evolving an Invasive Species 2014). Likewise they have caused billions of dollars in damage, and serious environmental destruction to the habitats they invade. This article proposed that evolution could assist in determining what introduced species will become harmful invasive species. In the end they discovered species with high phylogenetic diversity are more likely to be invasive than species with low phylogenetic diversity (Evolving an Invasive Species 2014). In all, this discovery is important because when a problem arises in a habitat and a biological organism is being proposed as a solution we can now analyze the organisms evolution to conclude if it will have a beneficial or detrimental affect on the

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.
