...., predation risk, competitive interactions). We present a hands-on activity for undergraduates using just a deck of cards, bingo chips, and dice to introduce ecological concepts of foraging theory, predator–prey interactions, and energy trade-offs. Specifically, this activity will focus on optimal foraging...

...Andrea M.-K. Bierema; David W. Rudge One of the key aspects of natural selection is competition, yet the concept of competition is not necessarily emphasized in explanations of natural selection. Because of this, we developed an activity for our class that focuses on competition and provides...

..., as well as attributes of successful invaders and the impacts of invasion on communities. We have developed a game to help students in grades 6–12 learn about the ecological effects of invasive species on native plant communities. “Race to Displace” models the competitive interactions among plant species...

...Wade B. Worthen Several common dragonfly species perch at different heights. Using dowels as perches and simple chi-square tests, this pattern of resource partitioning can be described quickly and easily. Additional experiments can examine the effect of interspecific competition on perch selection...
