Quantcast

o-DISC Deployed off One Tree Island

August 29, 2013

A study led by University of Miami scientist Claire Paris, which appears in the Aug. 28 edition of PLOS ONE, was designed to test the response of larvae in a natural open ocean setting using odor. The video shows a single settlement-stage larvae from a damselfish [Pomacentridae] in the central chamber of an o-DISC (ocean Drifting In Situ Chamber), which is transparent to light, sound and small scale ocean turbulence. The larvae uses odor cues to orient along the shoreline and toward the west. The implications of this study are significant, given that human activities might impact the smells contained within the ocean. If larvae cannot get their “wake up” cues to orient back toward the reef they may stay out at sea and become easy prey before finding home.
