A fish-derived bile salt was shown to act as interspecific infochemical, inducing the widespread predator avoidance behavior diel vertical migration at picomolar concentrations in freshwater zooplankton of the genus Daphnia.

The water flea Daphnia moves to deeper waters to avoid predators when it detects a chemical produced by fish.

Dubbed the 'green yeast', the model alga C. reinhardtii has profoundly advanced many areas of biology, but much remains to be learnt about its life in the wild.

The activation of Drosophila Or7a receptors guides aggregation and egg-laying behaviors towards both green leaf volatiles and a male-specific food-odor-induced pheromone.
