Invasive animal species

Purpose This paper will discuss the Great Lakes regions issue with invasive species introduced via ships ballast water, and the response that has followed since then. The impact of shipping and its economic benefit to the region will also be reviewed. The Great Lakes The great lakes system consists of a group of linked freshwater lakes spanning across the traditionally defined “heart land” region of North America. The system consists primarily of 5 distinct bodies of water; Lake Superior,…

North America, especially in North Carolina. Lionfish in the Atlantic Ocean have been classified as the worst marine invasion yet not just in the United States, but around the world as well. They travel extremely fast and spread more than other invasive species. Lionfish were first confirmed to be established off the coast of North Carolina in 2000. They have spread so fast that they have reached the caribbean are can be seen all the way in Venezuela. When lionfish come into contact with a reef,…

herbaceous graminoid components and several species of forbs. This ecosystem in Montana is also home to invasive species such as Bromus tectorum and Bromus japonicus. These species have long been known to proliferate in sagebrush ecosystems after a disturbances like a fire. A recent wildfire near Big Sawmill Gulch in Lewis and Clark County offers a unique look into plant diversity and competition in Montana’s sagebrush steppe ecosystem. How do these non-native species interact within the…

to lakes and rivers throughout the world by boats traveling internationally (NOAA, n.d). They were first discovered in the great lakes in 1988 (USGS. 2015). An invasive species is any non native species that has the potential to damage or destroy an ecosystem or environment, as well as human economy or well being (NNSS. 2015). Invasive…

Conservationists have had a tight focus on invasive species for decades. These species cross ecological boundaries and establish themselves in new areas where they affect the environment indefinitely. Conservationists are skeptical, and for good reason: Invasive species collide with natural environments and as follows, affecting biodiversity. Invasive species can benefit endangered environments; however, there should be stricter regulations of imported species to avoid the possibility of…

non-native species becomes controversial. The major issue that most people worried about is that whether non-native species threaten the natural environment. Mark Sagoff (2005) asserts that non-native species are not necessarily harmful. In response to Sagoff’s viewpoint, Simberloff comes up with opposing opinion that “major environmental impacts of non-native species…have both been demonstrated and judged by the public to be harmful” (Simberloff 2005, p595). To prove that non-native…

As outlined in the Landowner’s Guide to Managing & Controlling Invasive Plants in Ontario document, invasive species (such as buckthorn, dog strangling vine, and garlic mustard) negatively impact our native biodiversity. And pose a significant threat of establishing a monoculture in addition to creating a new environment that cannot sustain or support our native species anymore. In our region, buckthorn lacks any natural enemies and has a longer growing season. Which can provide it an unfair…

Invasive species are classified as a species that inhabits an unknown ecosystem that isn’t unique to its personal features. Several invasive species have inhabited the Americas especially through bodies of water. One specific organism, the snakehead, is harming the ecosystem in large lakes and waterways. The scientific name for this species is Channa argus since it pertains to the Channidae family. Although, this species is most commonly referred to as ‘snakeheads.’ This organism was quite…

The public's attention has recently been caught by species introduction and its resultant biotic invasions which are major components of global change. The last few decades have seen substantial advancements in invasion ecology which are succinctly summarised in this book. The deliberate or accidental introduction of organisms into a new ecosystem may cause the onset of a biological invasion. These so-called 'exotic species' may establish, spread and ecologically alter the invaded community.…

Within the past several decades, the zebra mussel Dreissena polymorpha has made its way to the top of the list as one of the most destructive invasive species in the North American water systems. While many studies have been made focusing on the ecological impact of zebra mussels, little is known about the geographical history of their invasions and patterns of genetic differentiation among and within populations in their native and invaded ranges (May, Gelembiuk, Panov, Orlova, & Lee, 2006).…
