		A Crosstown Walk to Assess Environmental Changes Along an Urban Socioeconomic Gradient In this Experiment, students examine the relationships between demographic factors (economic, social, etc.) and environmental quality. Students observe and collect data on the differences in...		More Info

		Acorn Foraging as a Means to Explore Human Energetics and Forge Connections to Local Forests In this article an unusual ecology laboratory/field exercise is described in which students imagine themselves as a group of indigenous woodland people attempting to gather food stores that will...

		An Assessment of Assemblage Nestedness in Habitat Fragments This experiment illustrates how ecological theory can help conserve native species in a fragmented landscape. It is germane to units on biogeography, human impacts on ecosystems, landscape...		More Info

		Are males cheaper than females? Male and female costs of reproduction In this TIEE experiment, students investigate the costs of reproduction. In dioecious plants, a female's investment in reproduction is typically much greater than a male's, because while both sexes...		More Info

		Biodiversity Responses across a Gradient of Human Influence To investigate how species, communities, and habitats change over the rural-urban (or pristine to human-dominated) gradient students conduct a series of biological inventories, field measurements,...		More Info

		Cemetery Demography This laboratory exercise examines the changes in human demographic patterns by visiting a local cemetery, collecting data recorded on tombstones, and producing a graphical representation of...		More Info

		Decomposition and Soil CO2 Emission Students investigate the factors that control the rate at which CO2 is emitted from soil using simple soil chambers and soda lime in a field experiment. Students in small groups design and conduct...		More Info

		Ecology of Habitat Contrasts: An Example from the Holyoke Range, MA This Experiment introduces students to a local ecosystem and what ecologists do: observe and describe patterns in organisms and then attempt to explain why those patterns exist. In the example used...		More Info

		Effects of Eastern Hemlock (Tsuga canadensis) on the Establishment of Interspecific Seedlings In this Experiment, students investigate the inhibitory effects of Eastern Hemlock trees on establishment of neighboring woody plants. Some years ago, one of the faculty in the Biology Department at...		More Info

		Environmental Correlates of Leaf Stomata Density In this Experiment, students make impressions of leaf stomata (using clear nail polish) and test a hypothesis of their choice about how leaf stomata density might vary under different environmental...		More Info
