Reliable statements about variability and change in marine ecosystems their underlying causes are needed to report on status guide management. Here we use the Framework Ocean Observing (FOO) begin developing ecosystem Essential Variables (eEOVs) for Southern System (SOOS). An eEOV is a defined biological or ecological quantity, which derived from field observations, contributes significantly assessments of ecosystems. Here, concerned with estimating trends properties, attribution causes,...
Abstract Sampling at appropriate spatial scales in the Southern Ocean is logistically challenging and may influence estimates of diversity by missing intermediate representatives. With assistance sampling efforts especially influenced International Polar Year 2007–2008, we gathered nearly 1500 specimens crinoid species Promachocrinus kerguelensis from around Antarctica. We used phylogeographic phylogenetic tools to assess its genetic diversity, demographic history evolutionary relationships....
The genus Conocrinus d’Orbigny, 1850 (Crinoidea, Bourgueticrinina) was established on the basis of two aboral cups that had previously been described as Bourgueticrinus thorenti d’Archiac, 1846. One these (now considered lost) came from “Rocher du Goulet” at base Biarritz section (Bartonian, Côte des Basques, southwest France). D’Archiac figured only second cup; this belongs to d’Orbigny Collection and is still housed in palaeontological collection Muséum national d’Histoire naturelle...
Abstract Despite significant advances in invertebrate phylogenomics over the past decade, higher-level phylogeny of Pycnogonida (sea spiders) remains elusive. Due to inaccessibility some small-bodied lineages, few phylogenetic studies have sampled all sea spider families. Previous efforts based on a handful genes yielded unstable tree topologies. Here, we inferred relationships 89 species using targeted capture mitochondrial genome, 56 conserved exons, 101 ultraconserved elements, and 3...
There has been a significant body of literature on species flock definition but not so much about practical means to appraise them. We here apply the five criteria Eastman and McCune for detecting flocks in four taxonomic components benthic fauna Antarctic shelf: teleost fishes, crinoids (feather stars), echinoids (sea urchins) crustacean arthropods. Practical limitations led us prioritize three historical (endemicity, monophyly, richness) over two ecological ones (ecological diversity...
Abstract In recent years, sea ice cover along coasts of East Antarctica has tended to increase. To understand ecological implications these environmental changes, we studied benthic food web structure on the Adélie Land during an event unusually high (i.e. two successive austral summers without seasonal breakup). We used integrative trophic markers (stable isotope ratios carbon, nitrogen and sulfur) build models explored feeding habits macroinvertebrates. total, 28 taxa spanning most present...
Most fossil feather stars are known only from the centrodorsal often connected to radial circlet. This is case for Discometra rhodanica (Fontannes, 1877), type species of genus Discometra, collected Late Burdigalian Miocene Rhône-Provence basin (southeastern France). The quarries operating in this area have exposed layers on northern flank Lubéron anticline near Ménerbes (basin Apt, Vaucluse, southeastern These contain exceptionally well-preserved echinoderms, among which three specimens a...
There is a growing interest in the exploitation of deep-sea mineral deposits, particularly on abyssal seafloor central Pacific Clarion-Clipperton Zone (CCZ), which rich polymetallic nodules. In order to effectively manage potential activities, thorough understanding biodiversity, community structure, species ranges, connectivity, and ecosystem functions across range scales needed. The benthic megafauna plays an important role functioning ecosystems represents component biodiversity. While...
<title>Abstract</title> Our knowledge of biogeographic patterns and processes in the deep sea has been limited by lack integrated datasets that cover its vast extent. Here we analyse a new global dataset genomic DNA sequences, spanning an entire taxonomic class benthic invertebrates (Ophiuroidea), to obtain broad understanding phylogenetic divergence biotic movement across all oceans, from coastal margins down abyssal plains. We show regional faunas on continental shelf are phylogenetically...
Abstract Numerous conceptual frameworks exist for best practices in research data and analysis (e.g., Open Science FAIR principles). In practice, there is a need further progress to improve transparency, reproducibility, confidence ecology. Here, we propose practical operational framework researchers experts ecology achieve building analytical procedures from individual projects production-level pipelines. We introduce the concept of atomization identify steps that support generalization by...
The main characters of the stalked crinoids family Pentacrinitidae attributed to genus Teliocrinus are re-evaluated from a quantitative study phenotype variation, new observations on arm and stalk articulations, observation ontogenetic trends. All specimens collected in northern Indian Ocean belong same species, i.e. springeri (Clark, 1909). However, two phenotypes living at different depths remain valid as subspecies: 1909) liliaceus shares several trends with Endoxocrinus, especially...
The South Orkney Islands Southern Shelf (SOISS) Marine Protected Area (MPA) was the first MPA to be designated entirely within high seas and is managed under Commission for Conservation of Antarctic Living Resources (CCAMLR). To assist with research monitoring MPA, an international expedition ('SO-AntEco') undertaken in austral summer 2016 contribute towards a better understanding selected benthic habitats region. assemblages SOISS region were found strongly correlated texture seafloor,...
Benthic marine biodiversity on the Antarctic continental shelf is high and unique, yet its distributional patterns are still relatively poorly understood. Some of main issues that biological data sparse, many species rare seem only weakly related to environmental conditions. Grouping by taxonomic or functional similarity has historically been used compensate for missing identification, generate a more widespread distribution data-points, this practice can help gain better understanding...
Abstract Background Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over last 150 years. In May–June 2017, IN2017_V03 expedition RV Investigator sampled LBA communities along slope and abyss Australia’s eastern margin mid-Tasmania (42°S) Coral Sea (23°S), particular emphasis on describing analysing patterns biodiversity that occur within newly...
Abstract Marine life of the Southern Ocean has been facing environmental changes and direct impact human activities during past decades. Benthic communities have particularly affected by such although we only slowly understand effect on species physiology, biogeography, distribution. Species distribution models ( SDM ) can help explore geographic responses to main changes. In this work, modeled four echinoid with contrasting ecological niches. Models developed for [2005–2012] were projected...
