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...

Teaching Exponential and Logistic Growth in a Variety of Classroom and Laboratory Settings
Ecology and conservation biology contain numerous examples of
populations growing without bounds or shrinking towards extinction. For these
populations, the change in the number of individuals generally follows an
exponential curve. On the other hand, limited resources may keep population
numbers in check and help maintain the population at the environment's carrying
capacity. These...

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...

Comparisons of Mycorrhizal Properties from Two Host Tree Species
In this lab experiment, students learn about ectomycorrhizal (ECM) fungal properties associated with two host tree species to better under understand symbioses in general and gain experience using soil sampling and mycorrhizal field methods. Students will learn in more depth about terms and concepts related to symbioses (e.g. mutualisms, coevolution, host specificity) and about specific...
