View Resource Using Stream Leaf Packs to Explore Community Assembly

In this TIEE experiment, students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic factors determine what organisms are present in a community. Students will make and install artificial leaf packs in a stream, wait for the leaf packs to be colonized by stream organisms, measure...

View Resource An in-class role-playing activity to foster discussion and deeper understanding of biodiversity and ecological webs

In a general sense, biodiversity is an intuitively simple concept, referring to the variety of Earth’s organisms. Ecologists, however, conceptualize biodiversity in a more nuanced, multidimensional way to reflect the enormous diversity of species, niches, and interspecific interactions that generate spatiotemporal complexity in communities. Students may not fully comprehend o...

View Resource Talking Turkey: Using a short story to facilitate learning and appreciation of energy flows through ecosystems

Human beings are storytellers. This exercise uses the universality of storytelling to engage undergraduate students in ecological science. Students read a fictional narrative that connects scientific principles of ecology to their daily life and in doing so helps students become more personally engaged in the scientific material and more interested in analyzing and evaluating the role of...

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...
