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.

View Resource Vulnerability of High Diversity Habitats to Introduced Species

This Issue focuses on a research article by Stohlgren et al. (2003) and two responses to it that were published in Frontiers in Ecology and the Environment. The article discusses the ecology of invasive species and the vulnerability of high diversity communities to invasives. Students, like many others, might assume that habitats with low plant diversity are more vulnerable to invasions of...

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 A community of wildflowers growing in a restored prairie in southwestern Wisconsin.

A community of wildflowers growing in a restored prairie in southwestern Wisconsin. The community pictured was open to foraging by meadow voles (Microtus pennsylvanicus), resulting in vegetation dominated by species that voles typically do not consume, particularly black-eyed Susans (Rudbeckia subtomentosa). In contrast, experimental plots that excluded voles were dominated by plant species that...
