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 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 ...

New research provides the latest evidence that climate change is having an impact on food webs in high-latitude ecosystems. Biologist Amanda Koltz of The University of Texas at Austin in the Alaskan ...

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to ...

Forever chemicals or PFAS double in concentration as they move up the food chain, increasing risks for top predators.

According to 130,000 years’ worth of data on what mammals have been eating, we’re in the midst of a mass biodiversity crisis. Not great! “While about 6 percent of land mammals have gone extinct in ...

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 ...
