  32. <meta content="The scale over which populations exchange individuals (migration) is central to ecology, and important for
  33. understanding recruitment and connectivity in commercial species. Field studies indicate that blacklip abalone (Haliotis
  34. rubra) have localised larval dispersal. However, genetic studies show differentiation only at large scales, suggesting
  35. dispersal over more than 100 km. Most genetic studies, however, have failed to test for subdivision at scales equivalent to
  36. field experiments.We used microsatellite DNA to investigate genetic structure at small scales (100m to 10 km) in blacklip
  37. abalone in south-east Tasmania.We found significant subdivision (FST =0.021; P<0.05) among sites, and hierarchical
  38. FST analysis indicated 64% of genetic variation was at the smallest scale, supporting field studies that concluded larval
  39. dispersal is less than 100 m. We also tested if genetic differentiation varied predictably with wave exposure, but found
  40. no evidence that differences between adjacent sites in exposed locations varied from differences between adjacent sites
  41. in sheltered populations (mean FST =0.016 and 0.017 respectively). Our results show the usefulness of microsatellites
  42. for abalone, but also identify sampling scales as critical in understanding gene flow and dispersal of abalone larvae in an
  43. ecologically relevant framework. Importantly, our results indicate that H. rubra populations are self-recruiting, which will
  44. be important for the management of this commercial species." name="eprints.abstract" />
