Effects of multiple invasive species in experimental aquatic communities
In this exercise, students first work in small groups to collect background information on what mosquitofish and bullfrogs consume and then modify a food web based on that knowledge. Students then develop hypotheses of how these two invasive species may affect native amphibian species, snails, and zooplankton. Following, students work individually to analyze experimental mesocosm data to determine the effects of the two invasive species on native aquatic taxa (amphibians, snails, zooplankton, and phytoplankton). Afterwards, students discuss their findings and modify their food web based on the results.
