Investigating the footprint of climate change on phenology and ecological interactions in north-central North America
The ecological questions in this exercise are:
1) Have long-term temperatures changed throughout Ohio? 2) How will these temperature changes impact plant and animal phenology, ecological interactions, and, as a result, species diversity?
This exercise is designed to give students experience working with large datasets and to allow them to use real ecological data to evaluate long-term...

Performing a population viability analysis from data students collect on a local plant
During two lab periods, students collect demographic data on perennial plants and then use these data in a matrix model to perform population viability analyses. During the first lab, students tag and record data on individual plants in the field. During the second lab, students compile these data to build transition matrices and then use R to run simulations. In the first year that instructors...

How do pawpaws affect tree regeneration?
In this study, students investigate whether and how much the native understory shrub pawpaw (Asimina triloba) may affect tree regeneration in a forested habitat. During one lab period in the field, they collect data on the densities of tree seedlings and saplings under varying densities of pawpaws. During a second lab period in a classroom, they test whether tree densities are lower under...

Issues in Ecology, Issue 17: Ecological Dimensions of Biofuels
The promise of biofuels as a renewable, environmentally friendly energy source has driven a worldwide expansion in their production. However, many questions remain about how to produce biofuels without causing new and unanticipated environmental impacts. This report summarizes the environmental effects of biofuels, illustrate some uncertainties about these effects, and identify topics for an...
