Researchers invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors' novel ...

A food web is a detailed interconnecting diagram that shows the overall food relationships between organisms in a particular environment. The simplest explanation is that food webs are "who eats whom" ...

A food web can be seen as a collection of pathways distributing energy to the ecological community. Because of thermodynamical as well as ecological constraints, some pathways are more important than ...

Estimated time of Completion: Activity and discussion can take up to 2 90-minute blocks depending on the amount of research Food webs show the interaction of different producers and consumers in an ...

In the Grand Canyon reach of the Colorado River, two species play an outsized role in the fate of mercury in the aquatic ecosystem, and their numbers are altered by flood events. In the Grand Canyon ...

The findings, published in this week's issue of Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. The ...

In research published last week in the journal Nature Communications, U.S. Geological Survey biologist Dylan Gomes and a team of researchers looked specifically at the food web and how energy is ...

In a new study published in the Proceedings of the National Academy of Sciences, authors Gabriel Gellner and Kevin McCann from the University of Guelph and SFI External Professor Alan Hastings (UC ...
