2008). Figure 1 shows a simplified food web in a desert ecosystem. In this food web, grasshoppers feed on plants; scorpions prey on grasshoppers; kit foxes prey on scorpions. While the food web ...

All organisms in an ecosystem depend on each other. Food chains show the flow of energy from one organism to another. Food chains show the feeding relationships between organisms. Food webs show ...

Climate change is depleting vital ocean nutrients, disrupting marine ecosystems, and threatening food webs, a new study finds ...

Food web interactions in lake ecosystems and disturbances affecting these interactions are one of the main topics in our research. In aquatic food webs, predation (top-down regulation) regulates the ...

The term keystone species was first coined by Robert Paine (1966) after extensive studies examining the interaction strengths of food webs in rocky intertidal ecosystems in the Pacific Northwest.

His lab studies the ecology of food webs, ecosystems, and watersheds, and most of our research occurs in freshwaters. Current research areas include: Animal-mediated nutrient cycling, including ...

and ecosystem multifunctionality. Researchers then proposed key trophic and non-trophic MNPs transfer pathways within and between the AG-BG food webs, including leaves-herbivores, flowers ...
