Ant~pathes fiordensis is a black coral species endermc to the south western reglon of New Zealand Restncted larval dlspersal has been demonstrated to occur In A fiordens~s although the exact scale of larval dlspersal is unknown Thls study examlnes the fine-scale (<50 m) pattern of relatedness between black coral colonles at 3 sltes in Doubtful Sound Fiordland to mfer dspersa l &stance and gain a better understanding of patch size in this species At each of the 3 sites the position of all black coral colonles was mapped and allozyme electrophoresis was used to determine the 10-locus genotype of each colony Two statlstlcal methods were used to examine the association between colony genotype and dlstance at each of the 3 plots, spatlal autocorrelatlon of ~n&vidual oci and Mantels Test which exanunes the relatlonshlp between multi locus genotypes At 1 of the 3 sites (Trlcky Cove) there was a signif~cant positive association among colonles separated by < 5 m for 4 of the 6 loci tested Sinularly Mdntel s Test showed a signdlcant positive correlation between genetic distance and Euclidean distance at the Tricky Cove site (r = 0 2 p = 0 007) These results suggest dlspersal of black coral larvae 1s highly philopatnc and that larvae settle very close to parent colonles However at the other 2 sites there was no spatial associabon detected among genotypes indicating either that gametes or larvae are more widely dspersed at these 2 sites (>50 m) or that other ecological and evolutionary factors are operating that have influenced the observed genetic structure of the populations Genetic stu&es suggest that gene flow in A f~ordensis populations ~ 1 1 1 be restncted and that patch size In this species may be relatively small These findlngs w l l have Important mlplications for the conservation and management of the rare and unique shallow water populations of black corals In New Zealand s flords
