Ant-following birds benefit from the relationship by staying just ahead of the ants and capturing prey animals that are disturbed by the ants. 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

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...
