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)
Major Biome Types (deserts, tropical rainforests, mixed deciduous forests, tundra, grasslands, coral reefs)

Types of water pollution (e.g., sewage, pathogens, nutrients, organic and inorganic chemicals)
Organisms:  (why?) Pfeisteria piscicida, three-toed sloth, zebra mussels, snakehead fish, snow leopard,
Baijy, Metasequoia, peregrine falcons
New Material
Methods of sewage treatment (primary, secondary & tertiary; Imhoff tanks or trickling filters for aeration;
types of sludge disposal methods; role of federal Clean Water Act)

Water Quality Testing (D.O., B.O.D., coliform tests, nitrates, phosphates, salinity, chlorides,
specific toxics testing, e.g., mercury, lead, pesticides, etc.)

Types and examples of drinking water problems (insufficient supply; 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, building practices, zoning issues,
drainage runoff, eutrophication, infrastructure costs, sustainable practices, etc.)
Problems associated with toxic chemicals (hormone disrupters, carcinogens, teratogens, mutagens)
Chemical toxicants (Pesticides, PCBs, mercury, dioxins, chorinated hydrocarbons,
radionuclides--see "Trace of the Black Wind")
Bottled water problems (petroleum for plastic, energy for shipping, etc.)

Global environmental issues (e.g., deforestation, toxic wastes, biodiversity losses, human overpopulation, stratosphere ozone depletion,
global warming, ocean pollution, toxic algae blooms,fishery decline, etc.)

Waste management problems (toxic waste disposal,, bioremediation of toxic wastesites)
Organisms:  (why?) Vorticella marina, lichens, mosses, zooxanthellae, Porpostoma, Condylostoma)
Important locations (Chernobyl, Ukraine; Minamata Bay, Japan; Love Canal, Niagara Falls, NY; Bhopal, India, Matunuck, RI)
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)
China's energy problems and solutions (extensive coal consumption, leading to higher air pollution; development of hydropower, specifically the Three Gorges Dam; consequences of impounding the Yangtze River behind the dam
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
(Missing web sites and updates will be posted as soon as I receive them)
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.)
Major environmental laws in the U.S., Clean Water Act, Clean Air Act, Safe Drinking Water Act, RCRA, CERCLA, TSCA, Oil Pollution Control Act)

Special Questions I: Choose ONE question; Prepare ahead of exam (5 points)
(Bring a word-processed copy of these questions with you to the exam)

(1) Identify a common pesticide (by name); describe the pesticide and its use; note any hazards associated with its use; know at least one alternative to using that particular pesticide.
(2) What are some of the impacts of exposure to methyl mercury? How widespread is this problem in the U.S.?
(3) What are some causes of coral reef bleaching and other types of degradation?
(4) What are some of the problems associated with nuclear weapons production at Hanford, Washington?
(5) Describe some factors related to the outbreaks of Pfiesteria in east coast estuaries?
(6) What are some of the health problems directly attributable to the Chernobyl nuclear accident in the Ukraine?
(7) Describe one of the more populous countries in the world and discuss how that nation is dealing with overpopulation?
(8) Discuss any one of the types of renewable energy, noting especially the applications for developing countries.
(9) Describe any one of the recent major oil spills (location, extent, damage, cleanup techniques used, present status).
