View Resource How many species are there? Determining species richness

One of the simplest questions an ecologist can ask about a site is how many species live there. The answer is important for basic researchers and managers alike, but can be deceptively hard to obtain. This exercise introduces students to the issues surrounding the estimation of species richness, and can be completed in a single three-hour lab session. Students will learn to collect data in the...

View Resource Patterns and process in Landscape Ecology: Physical template, biotic interactions, and disturbance regime

Ecological processes and patterns interact at various scales across landscapes. Spatially explicit consideration of pattern and process can better inform ecological questions. This Figure Set introduces students to the variability in scales of pattern and process and to the fundamentals of Landscape Ecology. TIEE

View Resource 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...

View Resource Agapostemon sweat bee

As global food demand increases, farmers are increasingly relying on single, managed bee species (often honey bees) to pollinate their crops. However, honey bees are not the best pollinators for all crops, and honey bee colonies have recently been experiencing health problems, notably colony collapse disorder. Recent research has shown that promoting a diversity of wild insect pollinators – suc...

View Resource Chemical Competition in Peatlands

These lab exercises were designed to enhance students’ understanding of the concept of chemical competition in ecology. They use the moss Sphagnum to illustrate the concept, which shows students that competition occurs between plants. Many of the traditional examples show competition as a physical battle between animals. By using the chemical alteration of the environment by Sphagnum, a teache...
