Assignment for Parasite Lab
1. What is the genus and species of the parasite we dissected out of minnow brains?
2. What stage in the parasite’s life cycle is this?
3. What is the definition of intensity in the parlance of parasitologists?
a. What was the mean ± 1 SE intensity from our data?
4. What is the definition of prevalence in the parlance of parasitologists?
a. What was the prevalence in the population of minnows we studied?
5. What are three different patterns of dispersion parasites can have?
a. Which type of dispersion did we find in our data set?
b. What does this dispersion pattern indicate about the parasite-host relationship
between Op and fathead minnows?
6. What is the relationship between body length and intensity in our data set?
a. Show the graph (with labeled axes and trendline added)
b. Is this trend statistically significant? State the F, df, and P to support this
statement.
c. What does this dispersion pattern indicate about the parasite-host relationship
between Op and fathead minnows?
