Exercise 1: The Everglades Ecosystem in Florida, U.S.A. is a very unique ecosystem with very important ecological, economic and social roles over the years. However this ecosystem has faced serious changes from introduced, non-native and invasive species.

Exercise: Discuss any two plant species and any two animal species that are affecting the Everglades. What are the challenges facing the native species and how are they adapting to the changing environment? List your references (at least three references are required).

Exercise 2: Background:

Coral reef ecosystems are located all over the world in warm, clean, clear and shallow tropical waters. They are often referred to as "the tropical rainforest of the ocean" because of their rich biodiversity. The largest coral reef is the Great Barrier Reef of Australia. Others are around the Caribbean Islands, off the coast of Florida, off the eastern coast of Africa, off the coast of Central America and also in the Red Sea. These ecosystems are facing serious threats both natural and man-made and the biodiversity in many of these areas is changing. Exercise:

Discuss any two serious problems that are affecting the coral reefs in the world today. Suggest solutions to these concerns. List your references (at least three references are required).

Exercise 3: Background:

There are many endangered and threatened plant and animal species in the world today.

Discuss any two plant and any two animal species that are either endangered of threatened in your state. What efforts is your state taking to protect these species from extinction? Are they successful? What extra actions would support these efforts to ensure higher success rates?
