Some introduced species become invasive! Give an example of an invasive species and one factor that explains why invasive species are often successful in colonizing new habitats.
Homework Answers
Chinese mitten crab(Eriocheir sinensis) is a classical example of an invasisve species.
High dispersal ability is one factor that explains the sucess of this invasive species in colonizing new habitat. After introduction from Asia (mainly from China and Korea) to North America and Europe, it became an invasive species due to its high dispersal ability. Significant inland migration, even hundreds of miles from sea or ocean, and requirement of sweet water, salt water and brackish water at different stages of growth and reproduction has intrigued this dispersal ability and eventual invasion in foreign land by this crab species. This one factor contributes greatly for this invasive species from Asiatic waters to colonize sucessfully at North America and Europe.

It has been proposed that some invasive species are successful because theyleave their natural enemies behind. Explain how this can result in a species having higher fitness in the invaded range and provide examples that either support or contradict this conjecture.

Asian carp are spreading north towards the Great Lakes at an alarming rate. Why are fisheries specialists trying so hard to keep them from entering the Great Lakes? They will physically crowd out the native fish. O They have the ability to disrupt the native food web. They do not make a good game fish. O They consume 20% of their body weight per day in small minnows. QUESTION 6 Which statement does not accurately describe the projected impacts of...

The cane toad has not yet reached Kakadu National Park in Australia. Many naturalists fear the cane toad's ability to disrupt the pristine ecosystems of this park. Given the cane toad's invasive characteristics, some believe that the only hope to stop the spread of cane toad populations in this region is through a biological control, such as the Introduction of a nonnative natural predator of the cane toad. Why might this idea be troubling? The deliberate introduction of another nonnative...
