View Resource 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 environment and human quality of life along a cross-town transect spanning a socioeconomic gradient in a city. The authors used a transect in Washington, DC that runs along T Street, spanning approximately 25...

View Resource The Floristic Relay Game: A Board Game to Teach Plant Community Succession and Disturbance Dynamics

This game introduces students to the concept of succession and plant community dynamics. Students learn that plant communities are dynamic (they change over time and space), and that these changes result from interactions between plants and biotic and abiotic aspects of their environments, as well as random events. Students play a board game in which each student represents an imaginary plant...

View Resource 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 by the author, students examine tree communities found on the north and south slopes of a local mountain (in the Holyoke Range, near Amherst, MA). Student-generated questions include: Are the tree...

View Resource 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 Hope College noticed that fewer seedlings and saplings of broadleaved woody species seemed to grow beneath the canopies of eastern hemlock trees than beneath the canopies of other species on the Hope...

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...
