“…We highlight the effectiveness of RAD‐Seq methods, which have recently been applied to examine the genomics of other coral reef fishes (Gaither et al., ; Picq, McMillan, & Puebla, ; Puebla, Bermingham, & McMillan, ; Saenz‐Agudelo et al., ; Stockwell et al., ), to study such nonmodel organisms. Our results show that in contrast to other cardinalfish species (Bernardi & Vagelli, ; Gerlach et al., ; Gotoh et al., ; Hoffman et al., ; Vagelli et al., ), S. tubifer exhibits genetic admixture over a 140‐km region despite the species’ demonstrated homing abilities and olfactory preferences for a home reef (Gould et al., ). These findings suggest that strong ocean currents combined with a month‐long pelagic larval phase promote dispersal and gene flow in the region.…”

Discrepancies between potential and observed dispersal distances of reef fish indicate the need for a better understanding of the influence of larval behaviour on recruitment and dispersal. Population genetic studies can provide insight on the degree to which populations are connected, and the development of restriction site-associated sequencing (RAD-Seq) methods has made such studies of nonmodel organisms more accessible. We applied double-digest RAD-Seq methods to test for population differentiation in the coral reef-dwelling cardinalfish, Siphamia tubifer, which based on behavioural studies, have the potential to use navigational cues to return to natal reefs. Analysis of 11,836 SNPs from fish collected at coral reefs in Okinawa, Japan, from eleven locations over 3 years reveals little genetic differentiation between groups of S. tubifer at spatial scales from 2 to 140 km and between years at one location: pairwise F values were between 0.0116 and 0.0214. These results suggest that the Kuroshio Current largely influences larval dispersal in the region, and in contrast to expectations based on studies of other cardinalfishes, there is no evidence of population structure for S. tubifer at the spatial scales examined. However, analyses of outlier loci putatively under selection reveal patterns of temporal differentiation that indicate high population turnover and variable larval supply from divergent source populations between years. These findings highlight the need for more studies of fishes across various geographic regions that also examine temporal patterns of genetic differentiation to better understand the potential connections between early life-history traits and connectivity of reef fish populations.

“…A population on an island off Liang which had been reduced to 13 individuals by 2004 has not recovered and was locally extinct at this site in June 2012 (Ndobe et al unpublished**). The high level of genetic population structure over distances as short as 2-5 km , Vagelli et al 2009) mean that local extinctions can result in the total loss of entire genetic strains and make re-stocking a controversial issue . Feeding habits.…”

“…Pterapogon kauderni, the Banggai cardinalfish (map not shown), is endemic to Indonesia and Malaysia. It has been the focus of three studies (Bernardi and Vagelli 2004, Hoffman et al 2005, Vagelli et al 2009) over most of its range, each using different markers. Further studies on other endemics could reveal mechanisms maintaining small ranges and genetic health of such species.…”

Marine biodiversity reaches its pinnacle in the tropical Indo-Pacific region, with high levels of both species richness and endemism, especially in coral reef habitats. While this pattern of biodiversity has been known to biogeographers for centuries, causal mechanisms remain enigmatic. Over the past 20 yrs, genetic markers have been employed by many researchers as a tool to elucidate patterns of biodiversity above and below the species level, as well as to make inferences about the underlying processes of diversification, demographic history, and dispersal. In a quantitative, comparative framework, these data can be synthesized to address questions about this bewildering diversity by treating species as "replicates." However, the sheer size of the Indo-Pacific region means that the geographic and genetic scope of many species' data sets are not complementary. Here, we describe data sets from 116 Indo-Pacific species (108 studies). With a mind to future synthetic investigations, we consider the strengths and omissions of currently published population genetic data for marine fauna of the Indo-Pacific region, as well as the geographic and taxonomic scope of the data, and suggest some ways forward for data collection and collation.
