		Ecology of Disturbance In this Issue, students will examine published data that address the ecological consequences of environmental disturbance. Disturbance is a useful topic in the teaching of ecology and about disputes...		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

		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...		More Info

		Elk (Cervus elaphus) search for food through snow in winter in the Rocky Mountains. Elk (Cervus elaphus) and other ungulates in the Rocky Mountains of North America must cope with food shortages and severe weather during winter. The strength of density-dependence in these ungulate...	You must be logged in to access all resource information.	More Info
