Marine food webs are highly complex. Until now, researchers have been unable to understand exactly how they are affected by climate change, overfishing and other threats. Scientists at the ...

Networks are a powerful way to represent the complexity of large ecological systems. However, most ecological networks, such as food webs, contain only partial lists of species interactions.

New research shows that marine heat waves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean's ability to buffer against climate change.

Coral reef ecosystems are being altered by rising ocean temperatures and increasing nutrient inputs, yet their combined influence on food-web structure is not well understood. Here we analyzed 130 ...
