Ecosystems face a combination of stressors that can interact in complex ways, leading to either synergistic (amplifying) or ...

After watching the video, students can construct a food web showing the interactions among the organisms on the island and in the ocean. Identify the producers and consumers in an ecosystem.

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 ...

Ecosystem-level evidence for top-down and bottom ... Several measures of trophic structure applicable to complex food webs. Journal of Theoretical Biology 83, 195–207 (1980).

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 ...

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species.

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 ...

When ecosystems are green ... Most of these communities are characterized by simple food webs with little redundancy of consumers, and producers that are single-celled phytoplankton, diatoms ...

A new method of tracking the dietary habits and contaminant exposure of animals in Arctic marine ecosystems is providing critical insights as climate change reshapes the region's food web.

This research not only brings new hope for sustainable agricultural production but also lays a strong scientific foundation ...
