While early studies suggested that the birds' foraging might in turn benefit the ants, it is possible that the birds remove prey that the ants would...

View Resource Testing Hypotheses about Herbivore Responses to Plant Vigor and Herbivore Impact on Plant Reproduction

In this laboratory exercise, students examine hypotheses about the interactions between goldenrod plants and the gall-forming insects that feed on them. Students collect and analyze data to determine 1) whether certain traits make the plants more susceptible to attack by the insects and 2) how plant reproduction is affected by the insects' feeding. Students are introduced to several competing...

The idea that oceans have pathogens that cause devastating diseases in a variety of organisms is less familiar to students than human diseases and medical treatment...
