__**Lab Concept Exam, Semester 1**__

Species Diversity Index- calculate the SDI, you will be given the formula
 * Given a list of organims present in an area, calculate the diversity index of each area. You will be given the formula- just know how to use it.
 * Be able to assess which area is more diverse than another area
 * List why biodiversity is valuable to an environment
 * Describe human practices that decrease biodiversity

Population
 * Draw a population histogram/pyramid given data of cohort sizes
 * Draw a survivorship curve given data on number of organisms surviving from year to year
 * Describe the predator-prey cycle and be able to interpret a graph of this cycling interaction
 * Calculate doubling time, growth rate, birth rate, death rate, given crude data
 * Suggest/outline an experiment to monitor population growth rate and r- vs. k- selected species

Water Quality
 * Describe the procedure for Biological Water Quality Sampling
 * bacteria test
 * macroinvertebrate test
 * Describe the procedure for Chemical Water Quality sampling
 * DO
 * Phosphorus
 * Nitrogen
 * Temperature
 * Chlorine
 * pH
 * Turbidity
 * Explain eutrophication using a bulleted list of steps (the series of ecological changes) and using a graph (show by graphing what happens to each component of the aquatic environment during eutrophication

Succession
 * Indicate the series of primary succession
 * Indicate the series of secondary succesion
 * Describe the difference between primary and secondary succession
 * List typical plants present during stages of succession (pioneer community --> climax community)

Sampling methods
 * Describe appropriate technique used to sample moving vs. non-moving communities
 * mark and recapture
 * quadrat
 * transect sampling

Ecological Interactions
 * Be able to draw a food web and label it using appropriate vocabulary
 * Determine the keystone species from a provided food web or information about community interactions
