Not all spotted cats are leopards: evidence for a Hemilienardia ocellata species complex (Gastropoda: Conoidea: Raphitomidae)
Provedor de dados: 5
Autores: Fedosov, Alexander E.; Stahlschmidt, Peter; Puillandre, Nicolas; Aznar-cormano, Laetitia; Bouchet, Philippe.
The small conoidean Hemilienardia ocellata is one of the easily recognizable Indo-Pacific "turrids", primarily because of its remarkable eyespot colour pattern. Morphological and molecular phylogenetic analyses revealed four species that share this "characteristic" colour pattern but demonstrate consistent differences in size and shell proportions. Three new species - Hemilienardia acinonyx sp. nov. from the Philippines, H. lynx sp. nov. from Papua New Guinea and H. pardus sp. nov. from the Society and Loyalty Islands - are described based on the results of phylogenetic analyses. Although the H. ocellata species complex clade falls in a monophyletic Hemilienardia, H. ocellata and H. acinonyx sp. nov. possess a radula with semi-enrolled or notably flattened...

Evaluation of large-scale unsupervised classification of New Caledonia reef ecosystems using Landsat 7 ETM+ imagery
Provedor de dados: 5
Autores: Bouvet, G; Ferraris, J; Andrefouet, S.
The capacity of the Landsat 7 Enhanced Thematic Mapper Plus sensor to classify the shallow benthic ecosytems of New Caledonia (South Pacific) is tested using a novel unsupervised classification method. The classes are defined by using a set of multiple spectral decision rules based on the image spectral bands. A general model is applied to the entire Southwest lagoon (5500 km(2)) and tested on three representative sites: a section of the barrier reef, a cay reef flat rich in corals, and a cay reef flat rich in algae and seagrass beds. In the latter one, the classification results are compared with a locally optimized model, with aerial color photographs and extensive ground-truthed observations. Results show that a reconnaissance of the main benthic...

Deglacial delta δ18 and hydrologic variability in the tropical Pacific and Indian Oceans
Provedor de dados: 5
Autores: Gibbons, Fern T.; Oppo, Delia W.; Mohtadi, Mahyar; Rosenthal, Yair; Cheng, Jun; Liu, Zhengyu; Linsley, Braddock K.
Evidence from geologic archives suggests that there were large changes in the tropical hydrologic cycle associated with the two prominent northern hemisphere deglacial cooling events, Heinrich Stadial 1 (HS1; similar to 19 to 15 kyr BP; kyr BP = 1000 yr before present) and the Younger Dryas (similar to 12.9 to 11.7 kyr BP). These hydrologic shifts have been alternatively attributed to high and low latitude origin. Here, we present a new record of hydrologic variability based on planktic foraminifera-derived delta O-18 of seawater (delta O-18(sw)) estimates from a sediment core from the tropical Eastern Indian Ocean, and using 12 additional delta O-18(sw) records, construct a single record of the dominant mode of tropical Eastern Equatorial Pacific and...

Spatial imprints of plate tectonics on extant richness of terrestrial vertebrates
Provedor de dados: 5
Autores: Descombes, Patrice; Leprieur, Fabien; Albouy, Camille; Heine, Christian; Pellissier, Loic.
Aim  In interaction with past climate changes, it is likely that plate tectonics contributed to the shaping of current global species diversity, but so far this has not been statistically quantified at the global level. Here, we tested whether plate tectonics since the breakup of Gondwana left an imprint on current patterns of species richness of amphibians, birds and mammals. Location  Global. Methods  We reconstructed the absolute positions of continental plates since the Early Cretaceous and used this information to derive variables of latitudinal shifts and potential exchanges among landmasses that could have modulated species richness. Using a multi-model inference approach combining both contemporary and historical variables, we quantified the...

Distributions of Indo-Pacific lionfishes Pterois spp. in their native ranges: implications for the Atlantic invasion
Provedor de dados: 5

Lionfish (Pterois volitans and P. miles) have become a major concern in the western Attantie and Caribbean since their introduction in the 1980s. Invasive lionfish can reach very high population densities on coral reefs in their invaded range, yet there are few data from their native range in the Indo-Pacific for comparison. We compiled data on the geographical distribution and density of Indo-Pacific lionfishes in their native ranges from published and unpublished underwater visual censuses and field collections. We found that lionfish in their native Indo-Pacific range are unevenly distributed, with higher densities in the Indian Ocean than in the Pacific. Lionfish densities increase significantly with increasing latitude, and are significantly higher in...

New Scleractinian corals (Cnidaria: Anthozoa) from Sabah, North Borneo. Description of one new genus and eight new species, with notes on their taxonomy and ecology
Provedor de dados: 16
Autores: Ditlev, H.
Eight new species and one new genus of Scleractinian corals from Darvel Bay, North-western Borneo are described and illustrated. Enigmopora darveliensis, Acropora ridzwani, Lithophyllon ranjiti, Pectinia crassa, Mycedium spina, Plerogyra multilobata, Plerogyra diabolotus, and Plerogyra cauliformis. The evolutionary and distributional significance of the species is discussed. Borneo’s unique equatorial location and stable geological history are held responsible for its high diversity of corals with a number of unique species. The morphology of Enigmopora darveliensis is discussed and compared to other supposedly primitive extant corals. The endemic status of most of the Plerogyra species, with their unusually large polyps, is due to their narrow ecological...

Habitat preferences of coral-associated wentletrap snails (Gastropoda: Epitoniidae)
Provedor de dados: 16
Autores: Gittenberger, A.; Hoeksema, B.W.
Examination of about 60,000 scleractinian corals of the families Dendrophylliidae, Euphylliidae and Fungiidae for the presence of associated wentletrap snails (Gastropoda: Epitoniidae) revealed various ectoparasitic life history strategies. Twenty Indo-Pacific wentletrap species were found, which were either host-specific or generalist. Most species were associated with mushroom corals, especially free-living species belonging to the Fungiidae. Snails showed different preferences with regard to their position relative to mushroom corals, the host’s size and its substrate. No preferences for depth were found. Infestation rates of mushroom corals in multi-species assemblages were negatively correlated with coral densities, which indicates that epitoniid...

Autores: Gittenberger, A.
This is the first record of an association between a wentletrap species (Gastropoda: Epitoniidae) and coral species of the Euphyllidae (Scleractinia), i.e. Plerogyra simplex and P. diabolotus. While describing Epitonium hartogi spec. nov., special attention is given to the ontogenetic development within the eggcapsules, the structure and microsculpture of the opercula, the radulae, and the microsculpture on the radular jaws. These characters proved to be at least partly diagnostic in the epitoniid species Epitonium albidum, E. billeeanum, E. costulatum, E. hoeksemai, E. ingridae, E. lochi, E. millecostatum, E. pyramidalis, E. twilae, E. ulu and Nitidiscala tincta.

The giant barrel sponge Xestospongia testudinaria is an ecologically important species that is widely distributed across the Indo-Pacific. Little is known, however, about the precise biogeographic distribution and the amount of morphological and genetic variation in this species. Here we provide the first detailed, fine-scaled (&lt;200 km2) study of the morphological and genetic composition of X. testudinaria around Lembeh Island, Indonesia. Two mitochondrial (CO1 and ATP6 genes) and one nuclear (ATP synthase β intron) DNA markers were used to assess genetic variation. We identified four distinct morphotypes of X. testudinaria around Lembeh Island. These morphotypes were genetically differentiated with both mitochondrial and nuclear markers. Our results...

A centuries old problem in nephtheid taxonomy approached using DNA data (Coelenterata: Alcyonacea)
Provedor de dados: 16
Autores: Ofwegen, L.P. van; Groenenberg, D.S.J.
The current centuries old classification of the family Nephtheidae is still mostly based on colony morphology. In this family the Indo-Pacifc genera Litophyton, Nephthea, Dendronephthya and Stereonephthya, and the Atlantic genus Neospongodes form a complex mix of closely related, poorly described species which cannot be recognized using only colony morphology. Attempts with the more modern approach of comparing skeleton composition (sclerites) have been only partly successful because of the extreme variation of sclerite forms present in these genera. The genus Chromonephthea Van Ofwegen, 2005, introduced for several species previously assigned to Dendronephthya, Nephthea and Stereonephthya, was established with sclerite morphology, but the true generic...

Zoantharia (Cnidaria: Anthozoa: Hexacorallia) of the South China Sea and Gulf of Thailand: a species list based on past reports and new photographic records
Provedor de dados: 16
Autores: Reimer, J.D.; Wee, H.B.; Put, A.; Hoeksema, B.W.
This study is the first review of Zoantharia species in the South China Sea and Gulf of Thailand. In addition to past literature records, new field observations are added from previously unexamined countries and regions. In total 16 species are listed, 15 of which belong to suborder Brachycnemina, and only one to suborder Macrocnemina. Two species are undescribed. The lack of Macrocnemina species is not likely indicative of a low diversity of this suborder in the South China Sea and Gulf of Thailand, but instead of an absence of research below shallow subtidal depths. As the majority of the new records from this study were randomly compiled by researchers who are not experts of Zoantharia, specific surveys by experts are needed in these two marine regions....

Part of the genus Lioconcha Mörch, 1853 is reviewed. Species strongly resembling Lioconcha castrensis (Linnaeus, 1758) are discussed and two new species are described: Lioconcha arabaya n. sp. from the Northwest Indian Ocean and Lioconcha rumphii n. sp. from Thailand and Sumatra. These three species, together with Lioconcha macaulayi Lamprell &amp; Healy, 2002, share many morphological similarities and we suspect them to be closely related. They are referred to as the Lioconcha castrensis species group. Furthermore, lectotypes of Venus castrensis Linnaeus, 1758, and Venus fulminea Röding, 1798, are designated. The latter is considered a junior synonym of V. castrensis.

Pseudo-imposex: male features in female volutes not TBT-induced (Gastropoda: Volutidae)
Provedor de dados: 16
Autores: Swennen, C.; Horpet, P.
The occurrence of a penis in female gastropods of the superfamily Muricoidea (infraorder Neogastropoda) has commonly been accepted as an indicator of tributyltin (TBT) pollution. Some species seem less sensitive than others, and one belonging to the family Columbellidae has been reported that it lacks the imposex response. During a survey in South-east Asian waters, females of Cymbiola nobilis and Melo melo (family Volutidae) with a small penis and an external vas deferens were initially considered as showing imposex. Doubt arose when 100% of the females had a penis on sites where other gastropods showed no or a low imposex incidence. During the present study, several hypotheses could be rejected such as (1) that the volutes are extremely sensible for TBT;...

Provedor de dados: 16
Autores: Reijnen, B.T.; Meij, S.E.T. van der; Ofwegen, L.P. van.
An overview of the octocoral and hydrozoan host species of pygmy seahorses is provided based on literature records and recently collected field data for Hippocampus bargibanti, H. denise and H. pontohi. Seven new associations are recognized and an overview of the so far documented host species is given. A detailed re-examination of octocoral type material and a review of the taxonomic history of the alcyonacean genera Annella (Subergorgiidae) and Muricella (Acanthogorgiidae) are included as baseline for future revisions. The host specificity and colour morphs of pygmy seahorses are discussed, as well as the reliability of (previous) identifications and conservation issues.
