In biology the relationship of what eats what and how energy passes through an ecosystem is called a food chain. Pyramids can help give us an overall picture of a particular food chain. They can ...
Trophic cascades are powerful indirect interactions that can control entire ecosystems. Trophic cascades occur when predators limit the density and/or behavior of their prey and thereby enhance ...
Defining plants as integral to any ecosystem as the primary producers feeding local wildlife as well as humans, experts say that changes in the sustainability of wild plants could have a catastrophic ...
Mentor(s): Hank Stevens, Ph.D. Invasive species that do not rely on ecosystem gaps are poorly understood, yet they pose serious threats to ecosystem health. This study focuses on O. undulatifolius and ...
