“…24 days), which gives opportunity for dispersal. Our findings concur with findings for many other marine fishes with long pelagic larval duration that do not show genetic structuring (Bay et al 2006;Teske et al 2010;Veilleux et al 2011), particularly in cases where biophysical factors (i.e. water circulation) allow the wide dispersal of larvae (Curley and Gillings 2009).…”

“…In addition, even with low sample size, the observed high gene flow and absence of genetic structuring for our three study species is valid, given the circumstances in the study such as (1) biology of the species studied, (2) water circulation, and (3) absence of barrier in the study area. Similar to our results, a number of marine fishes do not show genetic structuring using mtDNA CR at different scales (from hundreds to thousands of kilometres) (Fauvelot et al 2003;Horne et al 2008;Hickey et al 2009;Van Herwerden et al 2009a;Evans et al 2010;Teske et al 2010;Visram et al 2010;Veilleux et al 2011). In fact, even with the use of Table I.…”

“…In general, low sample size weakens the ability to detect genetic structuring. However, even the use of large sample sizes still showed no genetic structuring for many marine fishes (Purcell et al 2006;Curley and Gillings 2009;Christie et al 2010;Evans et al 2010;Teske et al 2010;Visram et al 2010;Saenz-Agudelo et al 2011;Veilleux et al 2011)-see Supplementary material.

“…In addition, continuous habitat (i.e. good coral reef condition) also contributes to connectivity of marine species leading to the absence of genetic structuring (Veilleux et al 2011), because continuous and good habitat tends to facilitate adult movement for many marine fishes (Chapman and Kramer 2000).…”

Integration of genetic connectivity information in effective marine reserve (MR) design is important in sustaining marine biodiversity. Here, genetic connectivity based on mitochondrial DNA (mtDNA) of three reef fish species, namely Epinephelus merra (n = 67; 32 from Bolinao, 14 from Alaminos, and 21 from Masinloc), Parupeneus multifasciatus (n = 23; 12 from Bolinao and 11 from Masinloc), and Odonus niger (n = 35; 21 from Mabini and 14 from Tingloy), sampled across western Luzon, Philippines, was inferred by assessing their genetic diversity, population genetic structure, and historical demography. The results show high haplotype and nucleotide diversity in the three species. Tests for population structure indicate high gene flow and no spatial genetic structuring for the three species. Mismatch analyses suggest unimodal distribution for E. merra and P. multifasciatus, but bimodal distribution for O. niger. Even with differences in mismatch distributions, all the three species exhibit low raggedness index indicating demographic population expansion. The bimodal distribution of O. niger could be attributed to the mixing of two isolated populations. High gene flow between sampling locations implies genetic exchanges and connectivity between many small MRs and fishing grounds in western Luzon, Philippines, at a scale similar to our study. This research is among the first few to elucidate the high genetic connectivity of reef fish communities across the Philippines (here western Luzon), but it also calls for more support (i.e. government and academia) for genetic research that aims to (1) understand the maintenance of megadiversity of the country and (2) search for effective biodiversity conservation options for the coral reefs.

“…Most marine ecological enquiry in NWA has focused on characterizing biodiversity, community assemblages and species distributions (Harvey et al., ; Hutchins, ; McKinnon, Duggan, Holliday, & Brinkman, ; McLean et al., ; Moore & Morrison, ; Moore, Morrison, Hutchins, Allen, & Sampey, ; Poore & O'Hara, ; Travers, Newman, & Potter, ; Travers, Potter, Clarke, & Newman, ; Travers, Potter, Clarke, Newman, & Hutchins, ; Wilson, ). A limited number of studies have investigated connectivity among the distinct but ecologically and economically important Australian coastal ecosystems (Broderick et al., ; Horne, Momigliano, van Herwerden, & Newman, ; Horne, Momigliano, Welch, Newman, & van Herwerden, , ; Johnson, Hebbert, & Moran, ; Johnson & Joll, ; Ovenden, Lloyd, Newman, Keenan, & Slater, ; Taillebois et al., ; Veilleux, van Herwerden, Evans, Travers, & Newman, ), and none have focused on inshore fishes with a comprehensive sample coverage across substantial environmental gradients. This emerging frontier in NWA therefore provides the ideal model system to increase our understanding of larval dispersal and connectivity in a management context.…”

Seascape genomics reveals fine‐scale patterns of dispersal for a reef fish along the ecologically divergent coast of Northwestern Australia

Understanding the drivers of dispersal among populations is a central topic in marine ecology and fundamental for spatially explicit management of marine resources. The extensive coast of Northwestern Australia provides an emerging frontier for implementing new genomic tools to comparatively identify patterns of dispersal across diverse and extreme environmental conditions. Here, we focused on the stripey snapper (Lutjanus carponotatus), which is important to recreational, charter-based and customary fishers throughout the Indo-West Pacific. We collected 1,016 L. carponotatus samples at 51 locations in the coastal waters of Northwestern Australia ranging from the Northern Territory to Shark Bay and adopted a genotype-by-sequencing approach to test whether realized connectivity (via larval dispersal) was related to extreme gradients in coastal hydrodynamics. Hydrodynamic simulations using CONNIE and a more detailed treatment in the Kimberley Bioregion provided null models for comparison. Based on 4,402 polymorphic single nucleotide polymorphism loci shared across all individuals, we demonstrated significant genetic subdivision between the Shark Bay Bioregion in the south and all locations within the remaining, more northern bioregions. More importantly, we identified a zone of admixture spanning a distance of 180 km at the border of the Kimberley and Canning bioregions, including the Buccaneer Archipelago and adjacent waters, which collectively experiences the largest tropical tidal range and some of the fastest tidal currents in the world. Further testing of the generality of this admixture zone in other shallow water species across broader geographic ranges will be critical for our understanding of the population dynamics and genetic structure of marine taxa in our tropical oceans.
