Originally belonging to African territories, the Gambian rat quickly became an invasive species to Florida. In general, the natural habitat of this mammal is not densely populated residential areas, but for several decades the Gambian rat has been causing damage to Floridas urban ecosystem, namely Grassy Key. Specifically, eight rodents were accidentally released by a…

The basic definition of an invasive breed is when one species native to a different habitat is transported into a foreign ecosystem. Without any natural predators, it completely messes up the food chain for the native genus. Some of the ways an invasive species takes over its host habitat is that it has no natural…

Exotic organisms cause a great harm to the existing a balanced ecosystem in forests and grasslands. Their devastating effects on ecology have led to long periods of research. However, there has been insufficient research on the impact of invasive plants on ecological associations in native communities (Klopfer, 2009). Their effects on a new environment is…

Modern man has built an empire. As a species, humans have made it to every continent, every ocean, and even space. The species did not begin this way; in fact, all modern humans can be traced to Homo erectus, a species that originated in Africa roughly 1.7 million years ago (Ayala 1995). Slowly making their…

There are many things that impact the environment and the ecosystems within them. Some of the impacts are beneficial, while others tear the ecosystem apart such as climate change, overpopulation and invasive species. While some of these events are natural many of these events are caused by the human population. In chapter five of Environmental…

From Giant Hogweed to feral cats Invasive species need to be stopped. Defining the Impact/Activity: Invasive species are species that have been introduced to an ecosystem that affect the habitats and bioregions they invade economically, ecologically, socially, and culturally in a negative manner. This paper will describe the intentional and non-intentional causes, ecological, social, cultural,…

In America, we have a growing issue of feral hogs, and they are becoming very destructive. Hogs are not native to America and are considered an invasive species also known as an alien species. Invasive species are a major problem that must be understood and controlled. Invasive species, as defined by the NOAA (National Oceanic…

A biome selected to describe is a tropical rainforest biome and an ecosystem chosen is the Amazon rainforest. This rainforest is among the largest in the world, having a wide variety of species. In this essay, the example of a keystone species, the Brazil nut tree, found in the biome and ecosystem will be provided.…
