“…Hybridization in reef fishes has a range of evolutionary consequences (Richards and Hobbs, 2014), even within a species complex (this study). These hybridization events provide exciting opportunities to investigate speciation in reef fishes and the role of introgression in structuring phylogenetic relationships (Kuriiwa et al, 2007). Although the use of genetic approaches is critical to confirm hybridization, it is also important to distinguish between incomplete lineage sorting, introgression and allele homoplasy (Henrique et al, 2016).…”

Although morphological characterization of hybrids is still common, molecular techniques can reveal hybrids that may otherwise go undetected (Kuriiwa et al, 2007;Montanari et al, 2012Montanari et al, , 2014 and the geographic extent of introgression (McMillan et al, 1999). Such advances are especially relevant for identifying hybrids between closely related species, which may be challenging to classify based solely on morphological characters.…”

Little population structure was observed within species, with evidence of recent population expansion across all four geographic ranges. We detected sharing of mtDNA haplotypes between species and extensive hybridization based on microsatellites, consistent with later generation hybrids but also the effects of allele homoplasy. Despite extensive introgression, 98% of specimens had 3 concordance between mtDNA lineage and species identification based on external morphology, indicating that species integrity may not be eroding. The A. nigricans complex demonstrates a range of outcomes from incomplete speciation to secondary contact to decreasing hybridization with increasing evolutionary depth.

“…Recent phylogenies of the family have provided evidence of a genetic basis for this dichotomy, with species from each body-shape and habitat group showing the closest phylogenetic relationships (e.g. Kuriiwa et al 2007). The deep-bodied, reef-associated clade exhibits limited morphological variation among species (Woodland 1990), and this morphology appears to have remained stable through time, with fossils of Eocene species displaying very similar body forms and similar bicuspid teeth (Bellwood 1996).…”

We explored the role of behaviour and trophic ecology in driving differences in ecosystem function between 2 closely related species. We examined the relationships between diet, feeding rate, alimentary tract structure and patterns of digestion for 2 reef herbivores commonly found on the Great Barrier Reef, Siganus doliatus and S. lineatus. Despite their similar morphology, the 2 species exhibited distinct feeding behaviours and significantly different feeding rates, diets and movements of digesta through the alimentary tract. S. doliatus displayed a typical herbivore diurnal feeding pattern, taking an average 9.7 bites min -1 over the main part of the feeding day and with a diet dominated by red thallate algae (primarily Laurencia spp., Eucheuma sp., Halymenia sp. and Gracilaria sp.) and red and green filamentous algae. S. lineatus was not observed taking a single bite from the reef substratum in >100 h of underwater observations. The stomach contents of S. lineatus were dominated by amorphous organic matter (detritus). Gut passage rates suggest that S. lineatus is feeding nocturnally or during crepuscular periods. We suggest that these 2 species have distinct functional roles, with S. doliatus being a grazer of reef turf algae and S. lineatus primarily a grazer of offreef detrital aggregates. This versatility of ecosystem function in closely related species provides further evidence that functional roles do not necessarily divide along taxonomic lines. The results highlight the importance of validating ecosystem function on a species-by-species basis.

“…Marine organisms that reproduce by releasing numerous eggs and larvae are able to disperse over large distances and can therefore be distributed over large geographic areas. Such marine organisms have a large population size, gene flow between distant populations occurs frequently, and interspecies hybridization sometimes occurs (Kuriiwa et al, 2007). Even geographically well-separated populations may be connected genetically, because there are few barriers to prevent gene flow in the oceans (Mayr, 1954;Palumbi, 1994).…”
