Phylogenies for Octopoda have, until now, been based on morphological characters or a few genes. Here we provide the complete mitogenomes and nuclear 18S 28S ribosomal genes of twenty specimens, comprising 18 species Cirrata Incirrata, representing 13 genera all five putative families (Cirroctopodidae, Cirroteuthidae, Grimpoteuthidae, Opisthoteuthidae Stauroteuthidae) six Incirrata (Amphitretidae, Argonautidae, Bathypolypodidae, Eledonidae, Enteroctopodidae, Megaleledonidae) which were...
Part of the European Union (EU) Common Fisheries Policy revision 2013 is a commitment to implement land-all policy, under which practice discarding caught fish back into sea will be forbidden. This measure applied first pelagic fleet in 2015, with phased implementation for demersal between 2016 and 2019. As part trials determine efficacy policy North Sea cod (Gadus morhua L.), Remote Electronic Monitoring (REM) systems were installed on seven Scottish vessels 2008. Vessels permitted...
Among octocorals, colonies of the deep-sea pennatulacean genus Umbellula Gray, 1870 are some most instantly recognisable forms. Historically however, species identification in this has been usually based on few morphological characters with very little knowledge associated intraspecific variability. This fact, combined limited access to these organisms, resulted numerous uncertainties about true that should be used determination and recognition synonyms questionable species. Recent...
The order Pennatulacea covers a group of specialized and morphologically distinct octocorals found in all oceans from intertidal areas to more than 6000 m depth. Sea pens constitute an important structural component marine soft-bottom communities by increasing the complexity these environments. Despite being both distinctive ecologically important, taxonomy systematics sea is still poorly understood. Recent molecular studies have shown existence convergent morphological features, making...
The taxonomy of Bathypolypus and Muusoctopus has long been confounded by poor original descriptions difficulty in distinguishing among species morphologically. We aimed to use DNA barcoding conjunction with delimitation techniques morphological identification mature males identify the present North-east Atlantic provide additional information on distributions. From 298 specimens collected during biannual Deepwater Timeseries cruises other aligned surveys undertaken Marine Scotland onboard...
Little is known about dispersal in deep-sea ecosystems, especially for sponges, which are abundant ecosystem engineers. Understanding patterns of gene flow sponges essential, areas where rising pressure from anthropogenic activities makes difficult to combine management and conservation. Here, we combined population genomics oceanographic modelling understand how Northeast Atlantic populations (Cantabrian Sea Norway) the sponge Phakellia ventilabrum connected. The analysis comprised ddRADseq...
We describe the complete mitogenomes of black corals
Among the main measures adopted to reduce anthropogenic impacts on elasmobranch communities, understanding ecology of deep-sea sharks is paramount importance, especially for potentially vulnerable species highly represented in bycatch composition commercial fisheries such as blackmouth catshark Galeus melastomus . In present work, we unravelled first indication population genetic structure G. by using a novel and effective panel nuclear, polymorphic DNA markers compared our results with...
Deep-sea North Atlantic sponge grounds are crucial components of the marine fauna providing a key role in ecosystem functioning. To properly develop effective conservation and management plans, it is to understand genetic diversity, molecular connectivity patterns turnover at population level species involved. Here we present study two congeneric sponges, Phakellia robusta hirondellei, using multiple sources evidence. Our phylogenetic fragment COI placed these as sister. Haplotype network...
Two new species of chemosymbiotic bivalves are described from a poorly localized site in the Hatton–Rockall Basin at 1187–1200 m. The Isorropodon mackayi sp. nov. is compared with others genus North and South Atlantic. A novel anatomical structure, suggested to be secondary gill, described. second bivalve Thyasira scotiae other known inhabit cold seeps Atlantic most resembles sarsi . Other than minor morphological differences, bathyal range presence commensal polychaetes, Antonbrunnia ,...
Whereas upper ocean pelagic sharks are negatively buoyant and must swim continuously to generate lift from their fins, deep-sea float or slowly buoyed up by large volumes of low-density oils in livers. Investigation the pressure, volume, temperature (PVT) relationships for liver 10 species Chondrichthyes shows that density difference between oil seawater, Δρ, remains almost constant with pressure down full depth (11 km, 1100 bar), theoretically providing buoyancy far beyond maximum...
Little is known about dispersal in deep-sea sponges, yet understanding patterns of gene flow and connectivity essential for their effective management. Given rising pressure from harmful anthropogenic activities, schemes that manage resource extraction whilst conserving species diversity are increasingly necessary. Here, we used ddRADseq derived SNPs to investigate the genetic sponge Phakellia ventilabrum across northeast Atlantic Ocean (from Cantabrian Sea Norway). The analysis 166...
<title>Abstract</title> The deep sea remains the biggest challenge to biodiversity exploration, and anthropogenic disturbances extend well into this realm, calling for urgent management strategies. One of most diverse, productive, vulnerable ecosystems in are sponge grounds. Currently, environmental DNA (eDNA) metabarcoding is revolutionising field monitoring, yet complex deep-sea benthic remain challenging assess even with these novel technologies. Here, we evaluate effectiveness...
The description in 1891 of the sea pen genus Gyrophyllum Studer, and also type species G. hirondellei was based on a single colony collected Azores Archipelago. During 19th 20th centuries, family placement this became controversial as set morphological features present could justify its assignation to both families Pennatulidae Ehrenberg, 1834 Pteroeididae Kölliker, 1880. Deliberations over intermediate characters finally ended reunification genera under by principle priority. use molecular...
