Trachinocephalus gauguini Polanco, Acero & Betancur, 2016 was described based on eighteen specimens collected from off the Marquesas Islands, only location where this species has been recorded until now. Through morphological and molecular examination of an exploratory cruise conducted in June 2014 under Tropical Deep-Sea Benthos program along northern coast New Ireland Province, Papua Guinea, we demonstrate presence Guinea waters. This new record suggests a wide distribution for rarely...
The Acanthomorpha is the largest group of teleost fishes with about one third extant vertebrate species. In course its evolution this lineage experienced several episodes radiation, leading to a large number descendant lineages differing profoundly in morphology, ecology, distribution and behavior. Although was recognized decades ago, we are only now beginning decipher large-scale, time-calibrated phylogeny, prerequisite test various evolutionary hypotheses explaining tremendous diversity...
Abstract Widely distributed bottom simulating reflectors (BSRs) imply the potential existence of gas hydrates offshore southwestern Taiwan. To compare distribution methane concentrations along passive and active margins in region, waters cored sediments were collected during four cruises from 2005 to 2006. The results reveal that sites with high are predominantly margin site GS5 is only contains very studied area. Anomalously fluxes still can be obtained calculation diffusive flux, although...
Abstract Chemical weathering modulates carbon transfer between the crust, hydrosphere, and atmosphere. The extent to which microbial processes are involved in mineral dissolution remains elusive. Here, we performed geochemical molecular analyses of river water other materials collected from a rapidly exhuming catchment eastern Taiwan. In addition solute generation driven primarily by pyrite-induced carbonate weathering, highly skewed community compositions with abundant Sulfuricurvum...
Abstract Flatfishes (Pleuronectiformes) are a species‐rich and distinct group of fishes characterized by cranial asymmetry. occupy wide diversity habitats, including the tropical deep‐sea freshwaters, often small‐bodied fishes. Most scientific effort, however, has been focused on large‐bodied temperate marine species important in fisheries. Phylogenetic study flatfishes also long limited scope placement monophyly flatfishes. As result, several questions systematic biology have persisted that...
In the northern South China Sea (SCS) we explored methane dynamics in water column during SONNE-cruise SO266 October/November 2018. Two depth zones contained elevated concentrations: upper 400 m ( 10°C and > 20°C, respectively. Both 16S rRNA gene pmoA amplicon analyses revealed distinct microbial methanotrophic communities with temperature of 27°C, ~10°C, 3°C. Second, found concentrations 200-400 FWCR-region whereas increased occurred uppermost 100 above SSFR. The deeper plume FWCR might be...
Abstract Identification of methane origins remains a challenging work as current diagnostic signals are often not sufficient to resolve individual formation and post‐formation processes. To address such knowledge gap in tectonically active fragmented terrain, samples from mud volcanoes, gas seeps, springs distributed along structural features onshore offshore Taiwan were analyzed for their isotopic compositions methane, nitrogen, helium, dissolved inorganic carbon, CO 2 , water. Our analyses...
Rhodopsin mediates an essential step in image capture and is tightly associated with visual adaptations of aquatic organisms, especially species that live dim light environments (e.g., the deep sea). The rh1 gene encoding rhodopsin was formerly considered a single-copy genomes vertebrates, but increasing exceptional cases have been found teleost fish species. main objective this study to determine what extent adaptation teleosts might shaped by duplication loss genes. For purpose, homologous...
Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns habitat descriptions. However, taxon identification from images is challenging often relies morphotypes without considering taxonomic framework. Taxon particularly in regions where the fauna poorly known and/or highly diverse. Furthermore, efficiency of imagery may...
Terrestrial mud volcanoes represent surface features of channels for subsurface methane transport and, therefore, constitute an important source emission from natural environments. How microbial processes regulate emissions in terrestrial has yet to be fully addressed. This study demonstrated the geochemical characteristics and communities four volcano seep sites two geological settings Sicily, Italy. At within accretionary wedge that exhibited higher sulfate concentrations, were dominated...
The coloured righteye flounder, Poecilopsetta colorata Günther, 1880 was previously known from the eastern Indian Ocean to South China Sea and Indonesia. Here, a new record western is reported. based on specimen collected Sakalaves seamounts at 375 m in depth Mozambique Channel during recent oceanographic survey. Four other teleost fish species including an uncommon ophidiid species, Neobythites somaliaensis Nielsen, 1995 were also same seamounts. presence of P. suggests broad Indo-West...
Methane hydrates are distributed throughout the South China Sea (SCS), and total abundance of methane hydrate in SCS is estimated to be 42.8Gt C. It has been revealed that tectonic transition may affect origin deposited sediments.Because sediment communities active (FWCR) passive (FR) margins off southwestern Taiwan were shifted diversified as burial progressed, we hypothesized microbial differentiation would vary fate organic matter utilization impact methane.In this study, supplied 13...
