How do pawpaws affect tree regeneration?
In this study, students investigate whether and how much the native understory shrub pawpaw (Asimina triloba) may affect tree regeneration in a forested habitat. During one lab period in the field, they collect data on the densities of tree seedlings and saplings under varying densities of pawpaws. During a second lab period in a classroom, they test whether tree densities are lower under...

Patterns and process in Landscape Ecology: Physical template, biotic interactions, and disturbance regime
Ecological processes and patterns interact at various scales across landscapes. Spatially explicit consideration of pattern and process can better inform ecological questions. This Figure Set introduces students to the variability in scales of pattern and process and to the fundamentals of Landscape Ecology. TIEE

Kids Into Discovering Science: A Framework for Place-Based, Hands-On Ecology
The Kids Into Discovering Science (KiDS) curriculum, designed for 5th grade students, includes 10 classroom lesson plans and one field trip lesson plan centered on a plant science experiment. Over 10 lessons and a field day, students practice observation, set up and monitor an experiment, analyze and present their data, and learn about plant ecology, soil ecology, habitats, and their local...

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...

Impacts of Introduced Species: Interspecific Competition, Predation, and Other Species Interactions
Due to increasing global connectivity, global biotic interchange has been escalating, leading to species introductions in regions in which they are not indigenous. Most of these species do not establish and/or do not cause significant impacts, but a small proportion do and can have positive or, more often, negative ecological, economic, and cultural impacts. These species often interact with...
