View Resource An oblique aerial view of the Mullica River showing an invasive reed (Phragmites australis) and two species of native grasses (Spartina spp.).

In this oblique aerial view of Hog Island in the Mullica River, a common reed (Phragmites australis; in green) is visible. P. australis was first observed spreading rapidly on upper Hog Island in...

View Resource Comparing the Influence of Precipitation, Fire, and Topography on Plant Productivity in the Tallgrass Prairie

This Data Set allows students to use long-term data from Konza to explore the relationships between multiple characteristics of a tallgrass prairie ecosystem and the productivity of prairie plants....

View Resource 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...

View Resource 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...

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...

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...

View Resource Effects of multiple invasive species in experimental aquatic communities

In this exercise, students first work in small groups to collect background information on what mosquitofish and bullfrogs consume and then modify a food web based on that knowledge. Students then...
