A plant enemy’s enemy

By Jill Richardson / April 3, 2013

When eaten by caterpillars, some plants can emit chemicals that signal the help of special wasps. Once called, a wasp lays its egg inside a caterpillar. Credit: Ted Turlings

Predators as climate helpers

By Janet Raloff / February 18, 2013

This freshwater stickleback eats the tiny animals in stream water that graze on plants and algae. This predation allows those plants and algae to collect and store carbon, rather than letting it escape into the atmosphere. Credit: Nicole Bedford, UBC

Threatened coral get fishy rescue

By Stephen Ornes / December 6, 2012

When toxic seaweed (green at right) gets too close to a type of coral (yellow structure), this fish, a broad-barred goby (Gobiodon histrio), responds to a distress signal sent by the coral and nibbles the seaweed away. Credit: Danielle Dixson
