Testing hypotheses about behavioral interactions between cats, coyotes, and birds at carcasses
In this activity, students will play the role of a field biologist quantifying and explaining animal behavior using the scientific method (observation – hypothesis – prediction – test). Powerpoint slides contain a series of photos of scavengers at deer carcasses. Students will form hypotheses about the behavioral interactions in the photos, then make predictions that could be used to test their...

Finding a species-area relationship for island birds using Solver in Excel
Grasping the mathematics underlying the species-area relationship in island biogeography can be difficult for students if they experience it passively. This exercise allows students to take an authentic data set of bird species richness from different islands in the Solomon Islands Archipelago and fit a species-area relationship (S=cAz). Students explore a biological concept in a hands-on...

Painting turtles: an introduction to species distribution modeling in R
Cooperative learning: Students can work through the exercises in groups, using either the painted turtle data
or group-specific taxa (i.e., each group selects a taxon to model). This module addresses multiple, complex
concepts online data availability & access, spatial query & analysis, global climate models, theoretical
concepts of SDMs, model fitting any of which can be expanded depending...

Catching ANOVA through mosquitoes
This activity is designed to show students how to perform an ANOVA using RStudio. To integrate the lesson plan with course content in an undergraduate ecology lecture course, students read an accessible scientific article (Chase & Knight 2003) that explores interaction between abiotic (climate and habitat permanence) and biotic (competition & predation) environmental conditions on the population...

How do Lake Ecosystems Change with Increases in Dissolved Organic Matter (DOM) and Reduced Water Clarity? Long-term investigations in lake ecology
Water quality is a significant issue affecting our lakes. While the effects of nutrients on water quality has received much attention, light availability also has strong effects on water quality in lake ecosystems. Light availability has been changing in many lakes with changes in water clarity. Many lakes are undergoing “browning”, where waters become darker and less transparent due to increases...
