We present data from a DNA taxonomy register of the abyssal benthic Echinodermata collected as part Abyssal Baseline (ABYSSLINE) environmental survey cruise 'AB01' to UK Seabed Resources Ltd (UKSRL) polymetallic-nodule exploration claim 'UK-1' in eastern Clarion-Clipperton Zone (CCZ), central Pacific Ocean plain. Morphological and genetic are presented for 17 species (4 Asteroidea, 4 Crinoidea, 2 Holothuroidea 7 Ophiuroidea) identified by combination morphological data. No taxa matched...
There is growing interest in mining polymetallic nodules from the abyssal Clarion-Clipperton Zone (CCZ) tropical Pacific Ocean. Despite being focus of environmental studies for decades, benthic megafauna CCZ remain poorly known. In order to predict and manage impacts CCZ, baseline knowledge essential. The ABYSSLINE Project has conducted biological surveys UK Seabed Resources Ltd polymetallic-nodule exploration contract area (UK-1). Prior these research cruises 2013 2015, no had been done...
DNA barcode sequences (a 657-bp segment of the mtDNA cytochrome oxidase I gene, COI) were collected from 191 species (503 specimens) Echinodermata. All five classes represented: Ophiuroidea, Asteroidea, Echinoidea, Holothuroidea and Crinoidea. About 30% specifically for this study, remainder came GenBank. Fifty-one represented by multiple samples, with a mean intraspecific divergence 0.62%. Several possible instances cryptic speciation noted. Thirty-two genera species, congeneric 15.33%. One...
Significance Tests of biodiversity theory have been controversial partly because alternative formulations the same seemingly yield different conclusions. This has a particular challenge for neutral theory, which dominated tests over last decade. Neutral attributes differences in species abundances to chance variation individuals’ fates, rather than traits. By identifying common features models, we conduct uniquely robust test across global dataset marine assemblages. Consistently, vary more...
Exon-capture studies have typically been restricted to relatively shallow phylogenetic scales due primarily hybridization constraints. Here, we present an exon-capture system for entire class of marine invertebrates, the Ophiuroidea, built upon a phylogenetically diverse transcriptome foundation. The captures approximately 90% 1,552 exon target, across all major lineages quarter-billion-year-old extant crown group. Key features our are 1) basing target on alignment orthologous genes...
A new classification of Ophiuroidea, considering family rank and above, is presented. The superfamily taxa in O’Hara et al. (2017) were proposed to ensure a better readability the phylogeny but are unavailable under provisions ICZN. Here, morphological diagnoses all 33 families five superfamilies provided. Ten families, Ophiosphalmidae fam. nov., Ophiomusaidae Ophiocamacidae Ophiopteridae Clarkcomidae Ophiopezidae Ophiernidae Amphilimnidae Ophiothamnidae nov. Ophiopholidae described....
Abstract The deep sea represents the largest and least explored biome on planet. Despite iconic status of Galapagos Islands being considered one most pristine locations earth, deep-sea benthic ecosystems archipelago are virtually unexplored in comparison to their shallow-water counterparts. In 2015, we embarked a multi-disciplinary scientific expedition conduct first systematic characterization invertebrate communities Galapagos, across range habitats. We seven sites depths over 3,300 m...
The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography. During five expeditions between 2009 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths 300–3600 m. Based these published literature, compiled voucher specimens, images, 274 newly DNA sequences present a taxonomic inventory macrofaunal megafaunal with focus invertebrates. In total 488 morphospecies were...
ABSTRACT Aim To test the hypotheses that seamounts exhibit high rates of endemism and/or species richness compared to surrounding areas continental slope and oceanic ridges. Location The south‐west Pacific Ocean from 19–57° S 143–171° E. Methods Presence/absence museum data were compiled for seamount non‐seamount at depths between 100 1500 m Ophiuroidea (brittle‐stars), an abundant speciose group benthic invertebrates. Large‐scale biogeographical gradients examined through multivariate...
Summary A common approach to nature conservation is identify and protect natural ‘assets’ such as ecosystems threatened species. While actions are essential, protection of assets will not be effective unless the ecological processes that sustain them maintained. Here, we consider role complementary perspective for arising from an emphasis on process. Many kinds biodiversity: including climatic processes, primary productivity, hydrological formation biophysical habitats, interactions between...
Abstract Aim The benthic fauna of seamounts typically includes organisms that are slow‐growing, long‐lived and sensitive to mechanical disturbance, making susceptible anthropogenic impacts. Such impacts may arise from mining cobalt‐rich crusts, envisaged for in the central North Pacific; this scenario requires environmental guidelines operations on be developed. Here, we provide biological information essential effective conservation planning deep‐sea features targeted such mining. Location...
Neuropeptides are a diverse class of intercellular signalling molecules that mediate neuronal regulation many physiological and behavioural processes. Recent advances in genome/transcriptome sequencing enabling identification neuropeptide precursor proteins species from growing variety animal taxa, providing new insights into the evolution signalling. Here, detailed analysis transcriptome sequence data three brittle star species, Ophionotus victoriae, Amphiura filiformis Ophiopsila aranea,...
The brittle star samples collected by the Danish cruise ‘Galathea II’ (1950–52) had not been studied completely. We examined remaining deep-sea (>400 m) and present species inventory, discussing taxonomic issues in relation to recent phylogenetic data. About 235 were examined, over 9,300 individuals, from 67 74 sampling localities, at depths of 425–5340 m. complex Amphiophiura bullata (Thomson, 1877) is morphologically well separated, but molecular data suggest least two clades. propose...
Abstract Aim To relate patterns of distribution marine echinoderms and decapods around southern Australia to major ecological historical factors. Location Shallow‐water (0–100 m) waters off Australia, south 30° S. Methods (1) Record the presence/absence known echinoderm decapod species in cells c . 1° latitude longitude, along coast mainland Tasmania. (2) Describe composition, richness endemism through gradient analysis, ordination cluster analysis. (3) Relate these distance temperature...
