Review Material
Definition of an ecosystem (trophic structure; types of ecosystems such as terrestrial, marine, aquatic, estuarine)
Biogeochemical cycles (carbon, nitrogen, phosphorus, and pollutants such as mercury or radionuclides)
Biomagnification of chemicals in the environment
 (e.g., pesticides, mercury, chlorinated hydrocarbons, radionuclides)
Biodiversity (species diversity; population interactions; keystone species, exotic species)
Hydrological Cycle (role of transpiration, precipitation, stormwater runoff, groundwater aquifers)
Types of water pollution (e.g., sewage, pathogens, nutrients, organic and inorganic chemicals)
Ecological succession (role of pioneer plants like lichens and mosses)
Organisms:  (why?) Pfeisteria piscicida, three-toed sloth, zebra mussels, snakehead fish, snow leopard,
Baijy, Metasequoia, peregrine falcons
New Material
Major Biome Types (deserts, tropical rainforests, mixed deciduous forests, tundra, grasslands, coral reefs)

Methods of sewage treatment (primary, secondary & tertiary, role of U.S. federal Clean Water Act)
Water Quality Testing (D.O., B.O.D., coliform tests, nitrates, phosphates, salinity, chlorides)
Types and examples of drinking water problems (insufficient supply or inaccessibility to clean water; surface reservoirs vs. groundwater aquifers;
public vs. private supplies; pollution episodes such as arsenic, MTBE, pesticides, etc.)
Land use issues (wetlands protection, vernal pools, drinking water quality, green building practices,
drainage runoff, eutrophication, infrastructure costs, sustainable practices, etc.)
Problems associated with toxic chemicals (hormone disrupters, carcinogens, teratogens, mutagens)
Chemical toxicants (Pesticides, mercury, chorinated hydrocarbons, radionuclides--see "Trace of the Black Wind")
  Global environmental issues (e.g., deforestation, toxic wastes, biodiversity losses, human overpopulation, stratosphere ozone depletion, global warming and climate change, ocean pollution, toxic algae blooms,fishery decline, etc.)
Waste management problems (toxic waste disposal, bioremediation, RCRA and CERCLA laws)
Organisms:  (why?) Vorticella marina, zooxanthellae, Metasequoia, Condylostoma, Porpostoma)
Important locations (Chernobyl, Ukraine; Minamata Bay, Japan; Love Canal, Niagara Falls, NY; Bhopal, India, Matunuck, RI, Tokashima, Japan)
China's population problems (size of population compared to land mass; growth rate and doubling time;
crowding and food supply issues; government intervention in controlling overpopulation; toxic pollution)
China's problems with endangered species (e.g., Baiji, giant panda and Metasequoia trees) and the country's attempts
to reverse these trends and to better manage rare and endangered species
Team Research Presentations (see web sites for details); available at:
http://web.bryant.edu/~langlois/ecology/ecoteamprojects.htm
Coral Reef Problems (values of reefs, causes of damage, research techniques, solutions)
Global warming issues (polar regions, equatorial regions, sea level, climate change, rainfall patterns, etc.)

Wetlands Protection (importance of wetlands, types of wetlands, International protection of wetlands)

Special Questions I - Complete ONE question; prepare ahead of exam on word processor (5 points each)
(Bring a word-processed copy of these questions with you to the exam)

(1) What are some of the health problems directly attributable to the Chernobyl nuclear accident in the Ukraine?

(2) Discuss some of the problems associated with frog populations throughout the world?
(3) What are some of the impacts of exposure to methyl mercury? How widespread is this problem in the U.S.?  What are the likely causes? 
(4) What are some causes of coral reef bleaching and other types of degradation?
(6) What is the present status of the Tokashima, Japan reactor facility?
(7) What are some of environmental factors associated with the earthquake devastaiton in Haiti?
(8) Describe some factors related to the outbreaks of Pfiesteria in East Coast estuaries?  What lessons can be learned?

(9) What is meant by the "ecological footprint"? What is being measured in the footprint analysis? Why is the U.S. footprint so large?

(10) What are some of the potential impacts of the Louisiana oil leakage on the coastal wetlands and estuaries along the Gulf of Mexico? Be specific.



Special Questions II - Complete this required question; prepare ahead of exam on word processor (10 points)
(Bring a word-processed copy of these questions with you to the exam)

(1) Choose an overpopulated country in the world.  Describe its situation (use some statistics) and then find out if that country (or perhaps a United Nations program, or NGO program, is in place to the help in the resolution of the problams associated with the overcrowding.  Use the foldout sheet in the back of your textbook to find the descriptive information.
