Abstract Distribution and species composition of deep-sea sponge grounds the Flemish Cap, Pass Grand Banks Newfoundland are described based on Spanish/EU bottom trawl groundfish surveys between 40 1500 m depth. Four areas with large catches sponges at least 30 different have been identified in study area. Geodia barretti, macandrewii, phlegraei, Stryphnus ponderosus Stelletta normani main structural constitute more than 94% total invertebrate biomass these grounds. The temperature salinity...
Artemisina Vosmaer, 1885 is a poecilosclerid microcionoid sponge genus with 20 valid species, seven of which have been recorded in the Atlantic Ocean.The present study describes grounds Iberia Peninsula. A. transiens described 1890 by Topsent Galicia (Spain); hispanica was also collected north Spain Ferrer-Hernández (1917); World Porifera Database (WPD) considers at moment both mushroom-shaped species as synonyms (van Soest et al., 2018), but we only able to check types hispanica. The...
Abstract In the deep ocean symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health services. We present a large-scale analysis microbial diversity in deep-sea sponges (Porifera) from scales sponge individuals to basins, covering 52 locations, 1077 host translating into 169 species (including understudied glass sponges), 469 reference samples, collected anew during 21 ship-based expeditions. demonstrate impacts abundance status, geographic distance,...
Macro and megafauna were studied in the Avilés Canyon System (ACS), southern Bay of Biscay (Cantabrian Sea), during several oceanographic cruises carried out from 2009 to 2017. The biodiversity ACS is summarized its description herein updated after sampling surveys programmes (ECOMARG, INDEMARES, SponGES, INTEMARES) conducted by Spanish Institute Oceanography (IEO). This study has previous knowledge canyon area past national international projects, their reports publications as well data...
The Galician Bank (GB) is a seamount in the Northeast Atlantic Ocean (Northwest Spain) at 180 km from coast. Its summit between 650 and 1500 m below surface as it rises abyssal plain 4000 depth. dynamics of water masses geomorphology area favour retention nutrients larvae, augmenting diversity benthic communities. present study aims to inventory reviewing echinoid fauna collected during LIFE+ INDEMARES project carried out on Bank. New findings are compared with previous studies Official...
The peripheral areas of deep-sea hydrothermal vents are often inhabited by an assemblage animals distinct to those living close vent chimneys. For many such taxa, it is considered that peak abundances in the periphery relate availability hard substrate as well increased concentrations organic matter generated at vents, compared background areas. However, peripheries less well-studied than assemblages vent-endemic and mechanisms through which fauna may benefit from environments generally...
Connectivity is a fundamental process driving the persistence of marine populations and their adaptation potential in response to environmental change. In this study, we analysed population genetics two morphologically highly similar deep-sea sponge clades (Phakellia hirondellei 'Topsentia-and-Petromica' clade, (hereafter referred as 'TaP clade')) at three locations Cantabrian Sea simultaneously assessed corresponding host microbiome by 16S rRNA gene sequencing. A virtual particle tracking...
Gorgonians play a fundamental role in the deep sea (below 200 m depth), composing three-dimensional habitats that are characterized by high associated biodiversity and playing an important part biogeochemical cycles. Here we describe use of benthic lander to monitoring polyps activity, used as proxy gorgonian feeding activity three colonies Placogorgia sp. Images cover period 22 days with temporal resolution 30 min. In addition, this seafloor observatory is instrumented oceanographic sensors...
<ns5:p>We present a genome assembly from an individual <ns5:italic>Aphrocallistes beatrix</ns5:italic> (Porifera; Hexactinellida; Hexasterophora; Sceptrulophora; Aphrocallistidae). The sequence is 100.50 megabases in span. Most of the scaffolded into 19 chromosomal pseudomolecules. mitochondrial has also been assembled and 18.0 kilobases length. Several symbiotic bacterial genomes were as MAGs, including Gammaproteobacteria Nitropumilaceae (Archaea).</ns5:p>
Sponges are a dominant element of the Antarctic benthic communities, posing both high species richness and large population densities. Despite their importance in ecosystems, very little is known about reproductive patterns strategies. In our study, we surveyed tissue six different for elements, namely, Dendrilla antarctica Topsent, 1905 (order Dendroceratida), Phorbas areolatus (Thiele, 1905), Kirkpatrickia variolosa (Kirkpatrick, 1907), Isodictya kerguelenensis (Ridley & Dendy, 1886)...
We describe the first application of a non-invasive and novel approach to estimate growth rate Asconema setubalense (Porifera, Hexactinellida) through use 3D photogrammetric methodology. Structure-from-Motion techniques (SfM) were applied videos acquired with Politolana ROTV in El Cachucho Marine Protected Area (MPA) (Cantabrian Sea) on three different dates (2014, 2017, 2019) over six years. With these data, multi-temporal study was conducted within framework MPA monitoring. A complete...
In the present work we focus on distribution of two species sponges. One these is Asconema setubalense , a sponge found in rocky substrate that was sampled with photogrammetric vehicle through georeferenced images. The other Pheronema carpenteri which inhabits soft bottoms and by beam trawl. For spatial modeling both sponges, geomorphological variables depth, slope, broad fine scale bathymetric position index (BPI), aspect, types were used, all resolution 32 m. Additionally, layers silicates...
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...
The Bay of Biscay is a structurally complex region, exhibiting high biodiversity and productivity hosting wide variety benthic habitats. Unfortunately, current scientific knowledge deep-sea ecosystems limited. Our investigation provides an updated vision the existing on key aspects ecosystem identifies research priorities for definition roadmap in support sustainable management, including protection conservation Biscay. To achieve this, firstly revision projects, surveys studies conducted...
Recent expeditions around New Zealand have revealed a surprising diversity of carnivorous sponges (Demospongiae, Poecilosclerida, Cladorhizidae). This is especially true for the Macquarie Ridge to southwest Zealand, with high numbers new species recently recorded. In this work we describe genus and Cladorhizidae Dendy, 1922 from Ridge, Cercicladia australis gen. nov. sp. nov., which has also, surprisingly, been found in deep Atlantic off coast Patagonia. addition mycalostyles sigmancistras...
The relationship between 3D terrain complexity and fine-scale localization distribution of species is poorly understood. Here we present a very reconstruction model three zones circalittoral rocky shelf in the Bay Biscay. Detailed variables are extracted from models using structure-from-motion (SfM) approach applied to ROTV images. Significant that explain location were selected general additive (GAMs) micro-distribution predicted. Two combining BPI, curvature rugosity can 55% 77%...
Deep-sea sponge-dominated communities are complex habitats considered hotspots of biodiversity and ecosystem functioning. They classified as Vulnerable Marine Ecosystem listed threatened or declining a result anthropogenic activities. Yet, studies into the distribution, community structure composition these scarce, hampering development appropriate management measures to ensure their conservation. In this study we describe diverse benthic community, dominated by lithistid sponge, found in...
Telestula humilis (Thomson, 1927) is a rare deep-sea stoloniferan octocoral distributed in the eastern Atlantic. Here we compared seven putative colonies of this species collected off Spain with lectotype from Oceanographic Museum Monaco and found them to be identical morphologically. Phylogenetic analyses on both full mitogenomes concatenated alignment containing two mtDNA genes (mtMutS Cox1) nuclear 28S rRNA gene recovered sister Incrustatus Inconstantia rather than other Telestula. This...
