View Resource Comparing the Influence of Precipitation, Fire, and Topography on Plant Productivity in the Tallgrass Prairie

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...

View Resource Life Under Your Feet: Measuring Soil Invertebrate Diversity

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....

View Resource Effects of Plant Biodiversity on Ecosystem Productivity within a Savannah Grassland Community

This Data Set focuses on the question: How does plant biodiversity in a grassland savannah community affect ecosystem productivity? To investigate this question, students use create graphs using seven years of data collected at Cedar Creek during an experiment set up to examine the effects of manipulating species richness on plant productivity and biomass. Cedar Creek Natural History Area is an...

View Resource Issues in Ecology, Issue 03: Non Point Pollution of Surface Waters

This report addresses pollution of aquatic ecosystems that originate from multiple unidentified sources or non point sources. Non point sources of phosphorus and nitrogen are of concern as they cause eutrophication or excessive enrichment of surface waters. Effects and remediation strategies are discussed. Non point sources, such as agricultural, urban and atmospheric ones are discussed. ...

View Resource Issues in Ecology, Issue 04: Biodiversity and Ecosystem Functioning

In this report, biodiversity and its relevance to the ecosystems that support humanity is discussed. Ecosystem functioning is defined as the collective activities of all biota within an ecosystem and how they affect its chemical and physical factors; therefore, it can be negatively impacted by decreases in biodiversity-the wide variety of life forms inhabiting the planet. The ecological and...
