How does grazing by bison affect plant community diversity? This TIEE Data Set introduces students to biodiversity and the concepts of richness, evenness, and diversity indices. It contains three computer-based activities in which students use Excel to explore three concepts in detail (species richness, the importance of sample size, and diversity indices) using plant species composition data from...

This Data Set allows students to use long-term data from Konza to explore the relationships between multiple characteristics of a tallgrass prairie ecosystem and the productivity of prairie plants. Specifically, students compare the interactive effects of fire frequency, topography, and inter-annual variation in precipitation on the productivity of two major plant groups (grasses and forbs). To...

This Experiment, students collect soil samples to test hypotheses about the diversity of invertebrates in soil in different places or under different conditions. Students generate their own hypotheses, and the activity is adaptable to available local conditions, such as different forest types, different stages of succession, or areas with and without impacts such as logging or wind damage....
