 Mercury contamination of edible freshwater fish poses a direct threat to human health. [http://en.wikipedia.org/wiki/Largemouth_Bass Largemouth bass] is a fresh water fish that was studied in 53 different Florida lakes to examine the factors that influence the level of mercury contamination. Water samples were collected from the surface of the middle of each lake in August 1990 and then again in March 1991. The '''pH level''', the '''amount of chlorophyll''', '''calcium''', and '''alkalinity''' were measured in each sample. Also, samples of fish were taken from each lake with sample sizes ranging from 4 to 44 fish. The age of each fish and mercury concentration in the muscle tissue was measured. Since [http://en.wikipedia.org/wiki/Mercury_(element)#Mercury_in_fish fish absorb mercury over time], older fish will tend to have higher concentrations. [http://en.wikipedia.org/wiki/Mercury_(element)#Safety Here is a detailed discussion] of why mercury accumilates in muscle tissues and why is it toxic in larger amounts.

Toxic chemicals, like ''heavy metals'' and estrogen mimicking compounds, may influence behavior. For instance, there are documented changes in how some animals respond to novel situations, vocalize, and expose themselves to the risk of predation as a function of chemical exposure. Thus, by quantifying time allocation using an event recorder (like [http://www.jwatcher.ucla.edu JWatcher]), and using various statistical analyses to analyze these data, it is often possible to have a behavioral indicator of chemical exposure. And, by quantifying such behaviors in a variety of species, and then using phylogenetic software (like [http://mesquiteproject.org/ Mesquite]), it is possible to study the evolution of such behavioral effects. We are in the process of developing new applets and learning materials demonstrating the effects of toxic exposure to such compounds on animal behavior.
