View Resource Teaching Exponential and Logistic Growth in a Variety of Classroom and Laboratory Settings

Ecology and conservation biology contain numerous examples of populations growing without bounds or shrinking towards extinction. For these populations, the change in the number of individuals generally follows an exponential curve. On the other hand, limited resources may keep population numbers in check and help maintain the population at the environment's carrying capacity. These...

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 soil sampling and mycorrhizal field methods. Students will learn in more depth about terms and concepts related to symbioses (e.g. mutualisms, coevolution, host specificity) and about specific...

View Resource A visit to the miniature forest Insights into the biology and evolution of Bryophytes in Northeastern Connecticut

The naturalist walking through the forests and wetlands of Northeastern Connecticut searches for the hidden flowers and listens to the songs of the birds. The mosses and liverworts that cover the trail bank, color the tree trunks in shades of green and form soft cushions or carpets on the boulders, typically pass unnoticed. Yet several hundred species of Bryophytes occur in our region, and...

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 develop hypotheses of how these two invasive species may affect native amphibian species, snails, and zooplankton. Following, students work individually to analyze experimental mesocosm data to determine...

View Resource Quantifying behavior learning observational protocols in the classroom

One of the challenges for teachers without a lab, is how to allow students to observe natural animal behavior directly. The freely available videos by the International Wolf Center are ideal for observation of naturalistic interactions, and last for long enough (5-15 minutes) to enable the practice of different observational techniques. This learning activity introduces novices to the...
