The discovery of non-cyanobacteria diazotrophs underneath Arctic sea ice could change our understanding of the food web, as ...

Polar bears are more than hunters as their leftovers feed many Arctic animals, forming a vital food web threatened by melting ...

Microbes near the surface of the Southern Ocean sustain the polar food chain — impacting the nutrient flow from the surface ...

The consequences of climate change are emerging in more visible and more disastrous ways. From climate refugees to diminishing habitats, it seems as though just about every species on planet Earth is ...

Phytoplankton is the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.

Food webs describe the trophic links between producers and consumers, and consumers and their predators, and are the most widely recognized representation of the interactions between species in an ...

Food chains and food webs are important ecological concepts that describe the relationships between species in an ecosystem and how energy is transferred between them. The two terms are used ...

Food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. The computations also reveal that small ecosystems follow other rules than large ...

Reconstructed food webs from the Ancestral Puebloan southwestern United States show the complexity and interconnectedness of humans, other animals, crops and the environment, in an area of uncertain ...

Webs aren’t just for spiders. They can, in fact, describe vast networks of interconnected relationships within ecosystems, based on the food preferences of plants and animals. Understanding a “food ...
