“…), who included the eastern Indian Ocean (including the Maldives and Chagos Archipelago) as part of their Indo‐Polynesian Province. Winterbottom & Emery () report E. sebreei from the Chagos Archipelago; however, colour photographs from this collection have a faded lateral stripe, and thus it is unclear whether E. sebreei , E. punyit or both (as in the Maldives) occur there. The fish faunas of the Chagos Archipelago and Maldives are predominantly comprised of species with wide Indo‐Pacific distributions ( i.e .…”

Here, multi-locus sequence data are coupled with observations of live colouration to recognize a new species, Eviota punyit from the Coral Triangle, Indian Ocean and Red Sea. Relaxed molecular clock divergence time estimation indicates a Pliocene origin for the new species, and the current distribution of the new species and its sister species Eviota sebreei supports a scenario of vicariance across the Indo-Pacific Barrier, followed by subsequent range expansion and overlap in the Coral Triangle. These results are consistent with the 'centre of overlap' hypothesis, which states that the increased diversity in the Coral Triangle is due in part to the overlapping ranges of Indian Ocean and Pacific Ocean faunas. These findings are discussed in the context of other geminate pairs of coral reef fishes separated by the Indo-Pacific Barrier.

“…Individuals were then identified and put into a 10% formalin-seawater solution for 5 d, then transferred into 70% ethanol. Identification of species was confirmed in the laboratory using taxonomic texts (Winterbottom 1985, Winterbottom & Emery 1986, Randall et al 1997, Meyers 1999, with the exception of Pleurosicya muscarum, which was identified by H. Larson (Northern Territory Museum, Australia). Where identification to species level could not be established, forms were denoted Sp.…”

An examination of the trophic status of a cryptobenthic reef fish community from the central Great Barrier Reef was carried out to evaluate the potential role of cryptobenthic fishes in coral reef ecosystems. Using frequency of occurrence data, dietary analyses revealed a diverse range of trophic groups, although detritivory (in 10 out of 16 species and 39.3% of individuals) and carnivory (5 of 16 species and 40.5% of individuals) clearly dominate as trophic modes. Herbivory (1 species; 2.4% of individuals) is only a minor component in the community trophic structure. Of the 18 dietary categories identified, detritus and copepods were the only constituents represented in all 16 species examined. Although the degree of dietary specialization varied among taxa, the 2 most abundant species, Eviota queenslandica and Istigobius goldmanni, utilised the broadest range of dietary items. Morphology reflected the trophic partitioning among fishes: carnivores were invariably < 28 mm total length (TL) and had gut-length ratios (GLRs) of < 0.5; detritivores were all > 38 mm TL with GLRs generally exceeding >1.0. The trophic composition and numerical strength of the cryptobenthic fish fauna suggests that cryptobenthic reef fishes have the potential to make a significant contribution to reef trophodynamics along a number of trophic pathways. This prompts a re-evaluation of the roles of reef fishes in the functioning of coral reefs, particularly those related to the recycling of primary production through detrital pathways.

Many fishes on coral reefs are known to associate with particula~ microhabitats If these associations help determine population dynamics then w e would expect (1) a close assoclation between the abundances of these fishes and the abundances of the most frequently used mlcrohabitats and (2) changes in the abundance of microhabitats would result in a corresponding change In fish population sizes We examined habitat associations among obligate coral-dwelling g o b~e s (genus Goblodon) and then investigated relationships between the spatial and temporal ava~labillty of habitats and the abundances of Goblodon species among locations and anlong zoncs on the leef at Lizard Island (Great Barrler Reef) Out of a total of 11 Acropora species found to be used by Gobiodon, each specic3s of Goblodon occupied 1 01 2 species of Acropora significantly more often than expected from the availability of these corals on the reef Across reef zones, the abundance of most species of Gobiodon was closely correlated with the abundance of coral species most frequently inhabited However, the abundance of 1 species G a x~l l a r~s .iiras not conelated with the availability of most frequently used corals aci oss reef zones or among locations Foi G axlllarls the1 efoi e factors other than habitat availab~lity weie more important In determining differences In abundance among zones and locations Also corielations between the abundance of 2 species, G histrlo and G quinquestrigatus, and the coral species they most frequently used was less cons~stent anlong locations than among zones This suggests that the relative importance of habitat availability in determining the abundance of these species of Goblodon is reduced at the spatial scale of locations around Lizard Island The population dynamics of Gob~odon during this study were closely linked to the population dynamics of host corals Because of a crown of thorns starfish (Acanthaster plancl) outbreak the abundance of corals declined in paiticular reef zones Cor~esponding with t h~s loss of h a b~t a t was a decline in Goblodon abundance This study demonstrated that the abundance of habitat specialised fishes can be closely correlated with the spatlal and temporal availab~lity of suitable habitats among and w~t h i n reefs
