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.

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 ...

Research conducted with the help of a University at Albany anthropologist has revealed the cascading effects that humans have had on mammal declines and their food webs over the last 130,000 years, a ...

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have ...
