This rat carried diseases that eventually wiped out a third of Europe. That species of rat could be considered an invasive species. An invasive species is a species that is not native to a specific habitat, and whose introduction can cause environmental harm or harm to another population. Some of the most significant negative effects of invasive nonindigenous species on native biodiversity are the result of direct predation (Chappell, et al., 2016). Invasive species can be plants, animals, fish, fungi, or even single celled organisms such as bacteria. Outside forces such as human interferences are how invasive species can be introduced to a new habitat. Exotic species that are introduced to a new environment can have a series of effects on preexisting symbiotic relationships as well as the environment, itself.
Invasive predators, such as the Lionfish often contribute to the decline in the populations of native species. In a study conducted by Ben F. Chappell and Kevin G. Smith of the biology department of Davidson College, patterns of selective predation by the invasive the Indo-Pacific lionfish (Pterois volitans/miles) were documented with the goal of identifying that are on the brink of population decline (Chappell et al., 2016). Lionfish feed on a variety of fish species. Chappell and Smith used published data on invasive lionfish stomach…
