A Functional Trait Perspective on the Biodiversity of Hydrothermal Vent Communities
FDvent: A functional trait perspective on the biodiversity of hydrothermal vent communities SCOR Working Group Proposal Title: A FUNCTIONAL TRAIT PERSPECTIVE ON THE BIODIVERSITY OF HYDROTHERMAL VENT COMMUNITIES Acronym: FDvent Abstract: Species diversity measures based on taxonomy, and more recently on molecular data, dominate our view of global biodiversity patterns. However, consideration of species functional traits, such as size, feeding ecology and habitat use, can provide insights into biodiversity patterns by representing how communities contribute to ecosystem processes. Moreover response traits, characteristics linked to how species respond to environmental change, have been linked to the processes underpinning community recovery following disturbance. We propose identifying functional traits for the global vent species pool to provide the first quantification of spatial and temporal patterns in functional diversity in this unique ecosystem. We will use expert knowledge and a literature review to identify both effect and response functional traits, and retrieve data for diverse macrofaunal and meiofaunal taxa. Our aim, given that trait-based measures provide a means to directly compare communities with species arising from different evolutionary trajectories, is to test whether vent communities from different biogeographic provinces display functional convergence while accounting for the geological and chemical settings. We will further test for change in functional diversity following the formation of new vents and disturbance events. This knowledge is critical for environmental management, given that hydrothermal vents are presently targeted for mineral resource exploitation by 2017. Our proposed working group will build an open-access traits database and offer a novel perspective on global biodiversity and succession patterns in vent communities. -

Exploring the Taxonomical and Functional Profile of As Burgas Hot Spring Focusing on Thermostable Β-Galactosidases
www.nature.com/scientificreports OPEN Exploring the taxonomical and functional profle of As Burgas hot spring focusing on thermostable β‑galactosidases María‑Eugenia DeCastro1, Michael P. Doane2,4, Elizabeth Ann Dinsdale2,3, Esther Rodríguez‑Belmonte1 & María‑Isabel González‑Siso1* In the present study we investigate the microbial community inhabiting As Burgas geothermal spring, located in Ourense (Galicia, Spain). The approximately 23 Gbp of Illumina sequences generated for each replicate revealed a complex microbial community dominated by Bacteria in which Proteobacteria and Aquifcae were the two prevalent phyla. An association between the two most prevalent genera, Thermus and Hydrogenobacter, was suggested by the relationship of their metabolism. The high relative abundance of sequences involved in the Calvin–Benson cycle and the reductive TCA cycle unveils the dominance of an autotrophic population. Important pathways from the nitrogen and sulfur cycle are potentially taking place in As Burgas hot spring. In the assembled reads, two complete ORFs matching GH2 beta‑galactosidases were found. To assess their functional characterization, the two ORFs were cloned and overexpressed in E. coli. The pTsbg enzyme had activity towards o‑Nitrophenyl‑β‑d‑galactopyranoside (ONPG) and p‑Nitrophenyl‑ β‑d‑fucopyranoside, with high thermal stability and showing maximal activity at 85 °C and pH 6, nevertheless the enzyme failed to hydrolyze lactose. The other enzyme, Tsbg, was unable to hydrolyze even ONPG or lactose. This fnding highlights the challenge of fnding novel active enzymes based only on their sequence. Termophiles, growing optimally at temperatures over 55 °C, are found in hot environments such as fumaroles, hydrothermal vents, hot springs, or deserts1–4. -
Comparative Analysis of the Complete Mitochondrial Genomes in Two
www.nature.com/scientificreports OPEN Comparative analysis of the complete mitochondrial genomes in two limpets from Lottiidae (Gastropoda: Patellogastropoda): rare irregular gene rearrangement within Gastropoda Jian‑tong Feng1, Ya‑hong Guo1, Cheng‑rui Yan1, Ying‑ying Ye1,2*, Ji‑ji Li1, Bao‑ying Guo1,2 & Zhen‑ming Lü1,2 To improve the systematics and taxonomy of Patellogastropoda within the evolution of gastropods, we determined the complete mitochondrial genome sequences of Lottia goshimai and Nipponacmea fuscoviridis in the family Lottiidae, which presented sizes of 18,192 bp and 18,720 bp, respectively. In addition to 37 common genes among metazoa, we observed duplication of the trnM gene in L. goshimai and the trnM and trnW genes in N. fuscoviridis. The highest A + T contents of the two species were found within protein‑coding genes (59.95% and 54.55%), followed by rRNAs (56.50% and 52.44%) and tRNAs (56.42% and 52.41%). trnS1 and trnS2 could not form the canonical cloverleaf secondary structure due to the lack of a dihydrouracil arm in both species. The gene arrangements in all Patellogastropoda compared with those of ancestral gastropods showed diferent levels of gene rearrangement, including the shufing, translocation and inversion of single genes or gene fragments. This kind of irregular rearrangement is particularly obvious in the Lottiidae family. The results of phylogenetic and gene rearrangement analyses showed that L. goshimai and Lottia digitalis clustered into one group, which in turn clustered with N. fuscoviridis in Patellogastropoda. This study demonstrates the signifcance of complete mitogenomes for phylogenetic analysis and enhances our understanding of the evolution of Patellogastropoda. -

Vent Fauna in the Okinawa Trough 34 Hiromi Watanabe and Shigeaki Kojima
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Springer - Publisher Connector Vent Fauna in the Okinawa Trough 34 Hiromi Watanabe and Shigeaki Kojima Abstract In deep-sea hydrothermal vent fields, faunal distribution is associated with geochemical environments generated by hydrothermal vent activity. The Okinawa Trough is located between the Eurasian Continent and the Ryukyu Arc, and is characterized by sediment- associated fauna associated with vents. In this chapter, the faunal distribution in hydrother- mal vent fields in the Okinawa Trough is summarized at inter- and intra-field levels, and its relationship with geochemical environments and species-specific ecologies is discussed. Although the zonation of sediment-associated fauna is not distinct, the fauna on rocky seabed can be categorized into four zones based on thermal conditions. Genetic connectiv- ity among conspecific populations in the Okinawa Trough appears to be common; further, a few faunal groups, such as tubeworms, show connectivity to regions outside of the Okinawa Trough. The faunal composition of vent communities in the Okinawa Trough has been categorized into three groups: the Minami-Ensei Knoll, Yoron Hole, and middle- southern Okinawa Trough. To determine more precisely the relationships between faunal composition and environmental factors in the Okinawa Trough vent fields, both generalized and vent-specific environmental factors should be measured simultaneously with quantita- tive faunal sampling for analyses. Keywords Biodiversity Connectivity Faunal similarity Zonation 34.1 Background Deep-sea hydrothermal vents are among the most flourishing deep-sea environments, due to the associated chemosyn- thetic bacterial productivity. The Okinawa Trough is a backarc basin located between the Eurasian continent and the Ryukyu island arc.
