Centropages mohamedi sp. nov. (Copepoda: Calanoida) is described from specimens collected in zooplankton samples off Obhur Creek on the Saudi Arabian coast of the central Red Sea. The new species is most closely related to C. orsinii Giesbrecht, 1889, a species described from the Red Sea and widely distributed in the neritic waters of the Indo-West Pacific region. The new species is mainly dist...

Photosymbiotic ascidian fauna were surveyed in the subtidal zone off Pari Island in the Thousand Islands (Java Sea, Indonesia). Nine species were recorded: Didemnum molle, Trididemnum miniatum, Lissoclinum patella, L. punctatum, L. timorense, Diplosoma gumavirens, D. simile, D. simileguwa, and D. virens. All of these species have been previously recorded in the Ryukyu Archipelago, Japan. Diplos...

Labidocerachuraumi sp. n. is described from Okinawa, southwestern Japan. The female of the new species differs from other congeners in genital compound somite with right postero-lateral and left antero-lateral processes. The male is distinguished from other congeners by the structure of the fifth leg. This new species is assigned to a newly proposed species group, the Labidoceramadurae species ...

Vocalizations of Indo-Pacific humpback dolphins (Sousa chinensis) in west Hong Kong waters were described from 12 recordings in 2010. A broadband hydrophone system recorded sounds. Vocalizations were characterized as broadband click trains, burst pulses, and narrowband frequency modulated sounds, including whistles generally similar to those of some other delphinid cetaceans. A comparison of re...

The Indo-West Pacific species, Neomerinthe erostris (Alcock 1896), originally described as Scorpaena erostris, is redescribed as a senior synonym of Scorpaena gibbifrons Fowler 1938, N. rotunda Chen 1981, and N. bathyperimensis Zajonz & Klausewitz 2002. Although the latter three nominal species have been regarded as valid species and N. erostris has not been reported since 1898, examinations of...

To assess patterns of connectivity among populations of an Indo-Pacific reef fish, we surveyed mtDNA of the bigscale soldierfish Myripristis berndti (Holocentridae), which is concentrated on reefs at intermediate depths, but occurs to at least 160 m. Our multi-scale approach included sampling at 11 sites spanning the entire range of the species from the western Indian Ocean to the eastern Pacif...

The banded coral shrimp, Stenopus hispidus (Crustacea: Decapoda: Stenopodidea) is a popular marine ornamental species with a circumtropical distribution. The planktonic larval stage lasts ∼120-253 days, indicating considerable dispersal potential, but few studies have investigated genetic connectivity on a global scale in marine invertebrates. To resolve patterns of divergence and phylogeograph...

[1] A set of Markov models is developed based on a statistical linearization of 5 coupled ocean‐atmosphere general circulation models used in the Intergovernmental Panel on Climate Changes Fourth Assessment Report (IPCC AR4), and is applied to ensemble prediction of the tropical Indo‐ Pacific sea surface temperature variations. By taking advantage of the long data records of IPCC simulations, t...

Abstract Conspicuous centers of biodiversity are frequently attributed to local conditions that promote speciation or resistance extinction, but recent diversification studies indicate this mode explanation might not be very general, so it may fruitful revisit the role dispersal in concentrating biodiversity. Here we consider processes underlying marine diversity hotspot Indo-West Pacific among...

We studied representatives of seven vetigastropod families in an extremely well-preserved Plio-Pleistocene mollusc fauna found in relatively deep water sediments (c. 200-300 m paleodepth) from the north-western Philippines. The fauna is systematically described and its paleoenvironmental and paleobiogeographical character is explored. Twenty-six species of gastropods were studied, three of whic...
