Within populations of brooding sessile corals, sperm dispersal constitutes
the mechanism by which gametes interact and mating occurs, and forms the
first link in the network of processes that determine species-wide
connectivity patterns. However, almost nothing is known about sperm
dispersal for any internally fertilizing coral. In this study, we
conducted a parentage analysis on coral larvae collected from an area of
mapped colonies, in order to measure the distance sperm disperses for the
first time in a reef-building coral and estimated the mating system
characteristics of a recently identified putative cryptic species within
the Seriatopora hystrix complex (ShA; Warner et al. 2015). We defined
consensus criteria among several replicated methods (COLONY 2.0, Cervus
3.0, MLTR v3.2) to maximize accuracy in paternity assignments. Thirteen
progeny arrays indicated that this putative species produces exclusively
sexually-derived, primarily outcrossed larvae (mean tm=0.999) in multiple
paternity broods (mean rp=0.119). Self-fertilization was directly detected
at low frequency for all broods combined (2.8%), but comprised 23% of
matings in one brood. Although over 82% of mating occurred between
colonies within 10 m of each other (mean sperm dispersal = 5.5 m ±4.37
SD), we found no evidence of inbreeding in the established population.
Restricted dispersal of sperm compared to slightly greater larval
dispersal appears to limit inbreeding among close relatives in this
cryptic species. Our findings establish a good basis for further work on
sperm dispersal in brooding corals and provide the first information about
the mating system of a newly identified and abundant cryptic species.
