“…There is a significant genetic break ( bootstrap values, 99 -100), there are no shared haplotypes, and corrected sequences diverge by 4.12% (29 diagnostic mutations). This genetic distance is comparable with or greater than that of other congeneric pairs of most reef fishes (e.g., angelfishes [Bellwood et al 2004, Randall andRocha 2009a]; but terflyfishes [Fessler and Westneat 2007]; grunts [Rocha et al 2008]; wrasses [Rocha 2004, Weaver and Rocha 2007, Luiz et al 2009, Randall and Rocha 2009b Randall (1956), compared with elsewhere in Oceania, are reproduced here as Tables 1 and 2. His decision to treat the two popula tions as a single species was based mainly on the similarity in color of Hawaiian to non Hawaiian individuals.…”

Abstract:The Blueline Surgeonfish, Acanthurus nigroris Valenciennes, formerly considered as wideranging in the central and western Pacific, is restricted to the Hawaiian Islands. Acanthurus nigros Günther, type locality Vanuatu, is available for the sister species from the Pitcairn Islands west to the Great Barrier Reef and Caroline Islands. Although these two species are very similar in color, there are finray and gillraker differences, and the genetic difference (i.e., 4.12% mtDNA cytochrome b sequence divergence) alone warrants species recognition.

“…According to previous research, the four species have similar habitat use, behaviour, and distribution in the Atlantic Ocean (Rocha et al 2008;Pereira and Ferreira 2013). Therefore, we tested the following questions: (1) is there an ontogenetic diet shift within Haemulon species and across different size classes (\5, 5.0-10, 10.0-15.0, and [15 cm)?…”

“…Juveniles tend to feed in the water column, whereas adults forage primarily on sand and rock (Pereira and Ferreira 2013). Despite this knowledge, changes in the diet composition according to ontogeny and food partitioning have never been analysed for Haemulon species in the South Atlantic Ocean where they have ecological, economical, and social importance on tropical coral reefs (Rocha et al 2008;Pereira et al 2011.…”

The genus Haemulon contains some of the most abundant and ecologically important reef fishes in the South Atlantic Ocean. However, their life history attributes have not been widely studied. Knowledge of ontogenetic changes in their resource use is critical to understanding the processes structuring natural communities. The present study analysed ontogenetic diet changes and food partitioning in Haemulon spp. We collected stomach contents from 276 individuals of four different size classes from four sympatric species (H. aurolineatum, H. parra, H. plumieri and H. squamipinna). There was a significant difference in the proportions of prey types between both species and size classes, providing evidence of food partitioning. Moreover, the Bray-Curtis similarity index revealed two distinct groups. The first consisted of larger-sized fish that consumed larger food items and the second group consisted of smaller individuals that fed on small invertebrates. There was an abrupt shift in the diet of Haemulon spp. at around 10.0 cm total length, a size that corresponds with the greatest morphological changes in the genus. Additionally, the diet overlap calculated by Pianka's index was more evident in smaller and larger size classes than in intermediate individuals. Together, these observations suggest Haemulon species undergo ontogenetic diet changes and food partitioning within species and size classes that are associated with changes in their habitat use, alongside morphological changes. Further research is needed to determine their ecomorphology and the competitive mechanisms that allow the coexistence of several sympatric and ecologically similar species of the genus Haemulon.

“…Paleontological evidence indicates that the split was already evident during the Late Oligocene, before the Tethys seaway linking the two realms was closed in the Early Miocene (19 Ma) and definitively ceased to exist after the Middle Miocene (Langhian, 16 Ma) (Harzhauser et al 2002(Harzhauser et al , 2007Harzhauser 2009). Further biogeographic differentiation within realms occurred later during the Miocene and Pliocene between the western and eastern Atlantic, between the northern Caloosahatchian and southern Gatunian Provinces in tropical America, between the Caribbean and Brazilian Provinces in the western Atlantic, between the northern and southern parts of the eastern Pacific, between the Indian and Pacific oceans in the IWP, and among the many island groups within the IWP, eastern Pacific and tropical Atlantic (Petuch 1982(Petuch , 1997(Petuch , 2004Woodring 1966;Pandolfi 1992;Williams and Benzie 1998;Vermeij 2001bVermeij , 2005bFloeter et al 2008;Frey and Vermeij 2008;Landau et al 2008;Rocha et al 2008;Timm et al 2008;Vogler et al 2008;Meyer et al 2005;Meyer 2003Meyer , 2004Gaither et al 2010).…”

Extralimital traits-evolutionary innovations that represent unprecedented departures from the phenotypic norm in the clade in which they arise-are often thought preferentially to evolve in island-like settings, but accumulating evidence indicates that they also arise in highly diverse, competitively rigorous ecosystems. In order to evaluate the origins of extralimital traits, I reconstructed the history of all ecological and shellmorphological innovations in Miocene to Recent shallow-water molluscs from the two great modern tropical marine realms, the Indo-West Pacific (IWP) and Atlantic-eastern Pacific (AEP), with the expectation that the more diverse IWP would show a higher incidence of innovation. Of the 66 innovations I identified, 53 (80%) are IWP and 13 (20%) are AEP in origin. Data on the numbers of living species in 26 molluscan clades in the two tropical realms indicate that the species ratio (AEP to total number of species 0.32 ± 0.115) exceeds the innovation ratio (AEP to total innovations 0.21). The perspecies frequency of innovation is therefore significantly higher in the IWP. None of the innovations is unique to endemic taxa on oceanic islands. I suggest that warm, large, highly productive environments are more conducive to the establishment of new ecological roles and phenotypic states than are smaller, less productive, more island-like settings; and that diversity need not be correlated with either high productivity or evolutionary opportunity for innovation.
