Invasive Species And Biodiversity Essay

1789 words - 8 pages

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.
Many studies suggest that implementing of a management strategy is although effective is costly and difficult to maintain. Most studies suggested that the best form for a strategy against invasive species is removal or implementing studies for early prevention of invasive attacks. Although must studies propose concepts for management plans many still have not figured out where the money will come from. Others have suggested plans that would cost less money. Simberloff & Gibbons (2004) suggest after their studies that a management plan that allows for the species to die off naturally should be considered. This allows for the decrease of the native population naturally within the environment. This would be a cost effective method without removal. The conclusion suggests that the natural crash of the species could also cause negative effects upon the species. It is noted that it shouldn’t be considered without further research on the subject and that the invasive species can leave a mark for longer than when they are there. Others like Sakai et al. (2001) analyze the various steps of invasion and suggest that evaluation of the threats of invasive species would be key to the finding a cost-effective management plan. The concept has strength...

The Impact of Invasive Species on Ecosystems

3082 words - 12 pages .  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 can make changes in a habitat’s physical structure, hydrology and salinity, productivity, energy flow, and fire cycle.  Declines in biodiversity occur

Invasive Species: Eurasian Milfoil

1232 words - 5 pages 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
