View Resource To Plant, or Not to Plant? Regulating Invasive Plant Species in the Mid-Atlantic States: A Social-Ecological System Case Study

As invasive plant species spread across landscapes, costs of their economic and environmental impacts have sparked interest in regulating their sale and transport. Laws now prohibit the sale and movement of some species. State and local governments are drafting regulations that will affect horticulture, plant nurseries, and options for landscape design. Awareness of invasive plant species is...

View Resource The nose knows: How tri-trophic interactions and natural history shape bird foraging behavior

This dataset is designed for first-year biology students, but can be altered for upper-level students. After receiving sufficient background on the biology of King penguins, students must make hypotheses regarding the penguins sensitivity to an odor known to be associated with the primary productivity of the ocean. Students are given multiple data sets and need to analyze the data using a...

View Resource Case Study on Mark and Recapture

Estimating the population size of animals is an important task for wildlife biologists, who can use the data to assess the health of a population. It requires diligent observation skills coupled with the ability to use empirical models that effectively determine the number of animals based on field surveys. The most common method for estimating the population size of animals is mark and recapture....

View Resource Egg size plasticity in bean beetles (Callosobruchus maculatus): Does host bean species matter?

In this exercise, students design a series of experiments (1) to test whether female bean beetles adjust the size of their eggs on different host bean species and (2) to determine whether differences in egg size based on host bean species are optimal. Most often, students design experiments in which different females are allowed to lay eggs on different bean species that vary in nutritional...
