Title: Smelly fish: orientation capabilities and mechanisms

Abstract: Reef fish as well as many other marine organisms sustain populations on isolated reefs and show genetic diversity between nearby reefs even though larvae of many species are swept away from the natal site during pelagic dispersal. Retention or recruitment to natal reefs ask for orientation capabilities that enable larvae to find their way. We show that olfactory imprinting on the parental population as well as on environmental cues of the natal reef could provide the necessary information.
