Bio Invasion

For the past few classes we have been learning about the biodiversities of ecosystems. Globalization has been one of the main causes that have led to the bio invasion of species. Professor Gangi described the rule of 10 for bio invasion. The rule of 10 is that for every 100 species, 10 are going to be able to reproduce in a new environment. One of the 10 species will be a nuisance species. Nuisance species usually affect the bio diversity of an ecosystem by bringing disease vectors and over competing with other species for resources. Professor Gangi talked about two particular species that I had no idea even existed. Honestly, I think I would prefer not knowing the existed. They are the snake fish and lamprey. The Lamprey is the first photo and the lamprey is the second photo. Both of these species have serious potential threats to waterways in the United States and other parts of the world. In the past they have been exposed into new environments and negatively affected the lives of other species living in the area. For example, the lamprey was able to get into waterways that weren’t its natural habitats and they can suck the blood of the fish living near it. A snake fish even has the ability to crawl out of bodies of water and move across land to another body of water. Both of these species have been able to make it to new waterways through the globalization of humans and can cause many problems in their new ecosystems.
