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 ...

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 ...

Ocean warming may lead to an increase in the biomass of species at the bottom of the food web, such as algae and cyanobacteria, but a decrease in the species that feed on those primary producers.

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 ...

ABSTRACT: Differential phenological responses to climate among species are predicted to disrupt trophic interactions, but datasets to evaluate this are scarce. We compared phenological trends for ...

Regime shifts between alternative stable ecosystem states are becoming commonplace due to the combined effects of local stressors and global climate change. Alternative states are characterized as ...
