First Time

The benthic ctenophore Vallicula multiformis Rankin, 1956 is recorded for the first time in the Arabian Sea, from the Gulf of Kutch, west coast of India in March 2013. This occurrence represents a remarkable extension of its geographic distribution that until now included only known the Pacific and Atlantic oceans.

The leafscale gulper (Centrophorus squamosus) is a wide-ranging deepwater benthopelagic shark threatened by commercial fisheries in parts of its range. Despite concerns about resource sustainability, little is known about the population structure and connectivity between critical habitats of the leafscale gulper. This study investigates the genetic population structure and the migration patterns of C. squamosus using nuclear microsatellites and mitochondrial NADH dehydrogenase subunit 2 (ND2) gene sequences. Genetic diversity was estimated and compared among sample collections from off Ireland, Portugal, the Azores, South Africa and New Zealand. The null hypothesis of genetic homogeneity among all collections was not rejected by the nuclear loci (FST (the overall genetic differentiation among sample collections) = –0.002, P = 0.88), but we found long-term genetic divergence between New Zealand and the remaining collections at the mtDNA ND2 (FCT (genetic differentation among groups of sample collections) = 0.366, P = 0.000). Migration rate estimates indicated limited female dispersal across the Indian Ocean whereas males showed less restricted dispersal. Our results are consistent with a single genetic stock of C. squamosus and the existence of sex-biased dispersal across the Indian Ocean. Widespread genetic homogeneity at nuclear loci minimizes the loss of unique adaptive genetic diversity in the event of localised depletion. However, high local fishing mortality may have far reaching impacts given the marked sex- and maturity-stage-based habitat partitioning previously reported for C. squamosus.

AbstractThe species of Diadegma that attack Plutella xylostella(Linnaeus) are revised. Following a morphometric study involving principal components and discriminant analyses, seven distinct morphospecies are recognized. One species is described as new: D. novaezealandiae from New Zealand. Diadegma mollipla(Holmgren) is the name for the species from sub-Saharan Africa and some Indian Ocean and South Atlantic islands. Diadegma varuna Gupta syn. nov. and D. niponicaKusigemati syn. nov. are both synonymized with D. fenestrale(Holmgren). Diadegma xylostellae Kusigemati is strongly presumed to be a synonym of D. semiclausum (Hellén). An illustrated identification key is provided and each species is described in a standard way.

FEW taxa have suffered at the expansion of humanity to the extent of the birds of Pacific Islands. Of the 130 or so birds to become extinct as a consequence of European exploration and colonization of the Pacific, most were island birds and most were flightless rails. Not so well understood is the scale of extinctions that accompanied pre-European colonization of the Pacific islands. Only now is the paleontological record revealing the richness of the lost Pacific avifauna much of which can be put on a par with the loss of moas from New Zealand and the Dodo Raphus cucullatus from Mauritius in the Indian Ocean.

The Eviota zebrina complex includes eight species of closely-related dwarfgobies, four of which are herein described as new. The complex is named for Eviota zebrina Lachner & Karnella, 1978, an Indian Ocean species with the holotype from the Seychelles Islands and also known from the Maldives, which was once thought to range into the Gulf of Aqaba and the Red Sea eastward to the Great Barrier Reef of Australia. Our analysis supports the recognition of four genetically distinct, geographically non-overlapping, species within what was previously called E. zebrina, with E. zebrina being restricted to the Indian Ocean, E. marerubrumsp. nov. described from the Red Sea, E. longirostrissp. nov. described from western New Guinea, and E. pseudozebrinasp. nov. described from Fiji. The caudal fin of all four of these species is crossed by oblique black bars in preservative, but these black bars are absent from the four other species included in the complex. Two of the other species within the complex, E. tetha and E. gunawanae are morphologically similar to each other in having the AITO cephalic-sensory pore positioned far forward and opening anteriorly. Eviota tetha is known from lagoonal environments in Cenderawasih Bay and Raja Ampat, West Papua, and E. gunawanae is known only from deeper reefs (35–60 m) from Fakfak Regency, West Papua. The final two species are E. cometa which is known from Fiji and Tonga and possesses red bars crossing the caudal fin (but lost in preservative) and a 9/8 dorsal/anal-fin formula, and E. oculineatasp. nov., which is described as new from New Guinea and the Solomon Islands, and possesses an 8/7 dorsal/anal-fin formula and lacks red caudal bars. Eviota oculineata has been confused with E. cometa in the past.

Madagascar and the Seychelles are Gondwanan remnants currently isolated in the Indian Ocean. In the Late Cretaceous, these islands were joined with India to form the Indigascar landmass, which itself then split into its three component parts around the start of the Tertiary. This history is reflected in the biota of the Seychelles, which appears to contain examples of both vicariance- and dispersal-mediated divergence from Malagasy or Indian sister taxa. One lineage for which this has been assumed but never thoroughly tested is the Seychellean tiger chameleon, a species assigned to the otherwise Madagascar-endemic genus Calumma . We present a multi-locus phylogenetic study of chameleons, and find that the Seychellean species is actually the sister taxon of a southern African clade and requires accomodation in its own genus as Archaius tigris . Divergence dating and biogeographic analyses indicate an origin by transoceanic dispersal from Africa to the Seychelles in the Eocene–Oligocene, providing, to our knowledge, the first such well-documented example and supporting novel palaeocurrent reconstructions.

AbstractWe provide the first record of the shallow and mesophotic (< 150 m depth) antipatharian coral Antipathes grandis VERRILL, 1928 from the Indian Ocean. First described from Hawaii, A. grandis was recently found on a mesophotic coral reef in SW Madagascar. Its identity was confirmed by means of morphological and molecular analyses (cytochrome c oxidase subunit I). These findings not only expand our knowledge of the potential geographic range of antipatharian corals, but also challenge the belief that only deep-sea (> 200 m depth) benthic taxa have such wide geographic distributions.

The 2004 Indian Ocean tsunami which exported death and destruction to far distant shores, once more emphasized the tsunami hazards associated with transoceanic tsunamis. Historical records of tsunamis in the Makran subduction zone (MSZ) reveal that Makran tsunamis are capable of producing large waves in the far-field. The Makran tsunami of 1945 produced by an Mw8.1 earthquake was reported to cause far-field effects in the Indian Ocean and reached a height of about 30 cm in the Seychelles, at the distance of about 3500 km from the MSZ. Here, we assess historical observations of this event and perform numerical modeling of this tsunami with emphasis on its far-field effects. Our numerical modeling successfully reproduces most feathers of the historical observations including its far-field effects. Southward propagation of Makran large tsunamis is investigated and their possible effects on Maldives and Seychelles islands are discussed. This study will help to better understand tsunami hazard associated with the MSZ, especially its far-field hazard.
