LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of disper ....LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of dispersal in two coral reef fish species. The relative importance of retention and connectivity will be measured, from a large scale encompassing different regions (Great Barrier Reef and Papua New Guinea) to a small scale focussing on individual reefs.Read moreRead less
