As you weed, so shall you reap: On the origin of algaculture in damselfish

Abstract

Within their territories, damselfish cultivate particular algae for consumption. A recent study in BMC Evolutionary Biology shows extensive variation among and within fish species in the composition of these algal 'gardens', varying from monocultures to cultures of mixed species, and in the mode of cultivation. This fish-algal agriculture may provide insight into the early stages of domestication. © 2010 Aanen; licensee BioMed Central Ltd.
