Gastropods are a highly diverse clade of molluscs that includes many familiar animals, such as limpets, snails, slugs and sea slugs. It is one the most abundant groups animals in only molluscan lineage has successfully colonized land. Yet relationships among within its constituent clades have remained flux for over century morphological, anatomical molecular study. Here, we re-evaluate gastropod phylogenetic by collecting new transcriptome data 40 species analysing them combination with...
Many marine meiofaunal species are reported to have wide distributions, which creates a paradox considering their hypothesized low dispersal abilities. Correlated with this is an especially high taxonomic deficit for meiofauna, partly related lower effort and number of putative cryptic species. Molecular-based delineation barcoding approaches been advocated biodiversity assessments speed up description processes uncover lineages. However, these show sensitivity sampling coverage (taxonomic...
Abstract Strong currents and deep passages of water can be barriers for larval dispersal continental marine animals, but potential effects on direct developers are under‐investigated. We examined the genetic structure Doris kerguelenensis , a directly developing sea slug that occurs across Drake Passage, body separating Antarctica from South America. found mitochondrial divergences within populations both sides American animals formed multiple sister‐group relationships with Antarctic...
The exploration of Earth's biodiversity is an exciting and ongoing endeavour. Here, we report a new species seadragon from Western Australia with substantial morphological genetic differences to the only two other known species. We describe it as Phyllopteryx dewysea n. sp. Although leafy ( Phycodurus eques ) common taeniolatus occur along Australia's southern coast, generally among relatively shallow macroalgal reefs, was found more offshore in slightly deeper waters. holotype trawled east...
A well-supported evolutionary tree representing most major lineages of scleractinian corals is in sight with the development and application phylogenomic approaches. Specifically, hybrid-capture techniques are shedding light on evolution systematics corals. Here, we reconstructed a broad phylogeny Scleractinia to test previous phylogenetic hypotheses inferred from few molecular markers, particular, relationships among families genera, identify clades that require further research. We...
The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5° 2°C United Nations Paris Agreement. Knowledge ice loss during similarly warm past climates could resolve this uncertainty, including Last Interglacial when global sea levels were 5 10 meters higher than today average temperatures 0.5° 1.5°C warmer preindustrial levels. Using a panel...
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 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....
Antarctica's rich marine animal biodiversity has been substantially influenced by a complex glacial history, but it is unclear why some taxa responded with diversification while others did not. Despite being considered single endemic sea slug species in the Southern Ocean, mitochondrial DNA sequencing of Doris kerguelenensis (Bergh, 1884) revealed multitude highly divergent lineages. But because uniparental inheritance mitochondria, was whether those lineages represented radiation cryptic or...
Increased exploration of northeastern Pacific deep-sea habitats has revealed a diverse and often poorly-known invertebrate community, including number undescribed species nudibranchs studied herein. We used morphology to distinguish several new from their congeners, generated data where possible for mitochondrial (COI, 16S) nuclear markers (H3) place them in phylogenetic context. described here Tritonia nigritigris sp. nov., Dendronotus claguei Ziminella vrijenhoeki Cuthona methana Aeolidia...
The isolation and characterization of two new tricyclic sesquiterpenoids, shagenes A (1) B (2) are presented. These compounds were isolated from an undescribed soft coral collected the Scotia Arc in Southern Ocean. One- two-dimensional NMR spectroscopy mass spectrometry provided data necessary to characterize their relative stereochemical configurations. Exploration bioactivity found 1 active against visceral leishmaniasis causing parasite, Leishmania donovani, with no cytotoxicity mammalian host.
Since its description from the Galapagos Rift in mid-1980s, Archinome rosacea has been recorded at hydrothermal vents Pacific, Atlantic and Indian Oceans. Only recently was a second species described Pacific Antarctic Ridge. We inferred identities evolutionary relationships of representatives sampled across vent range genus, which is now extended to cold methane seeps. Species delimitation using mitochondrial cytochrome c oxidase subunit I (COI) recovered up six lineages, whereas...
Abstract Euthyneuran gastropods represent one of the most diverse lineages in Mollusca (with over 30,000 species), play significant ecological roles aquatic and terrestrial environments affect many aspects human life. However, our understanding their evolutionary relationships remains incomplete due to missing data for key phylogenetic lineages. The present study integrates such a neglected, ancient snail family Ringiculidae into molecular systematics Euthyneura first time is supplemented by...
Signatories to the Antarctic Treaty System's Environmental Protocol are committed preventing incursions of non-native species into Antarctica, but systematic surveillance is rare.Environmental DNA (eDNA) methods provide new opportunities for enhancing detection and biosecurity monitoring.To be effective biosecurity, eDNA tests must have appropriate sensitivity specificity distinguish from native species, fit-for-purpose.This requires knowledge priority risk or taxonomic groups which will...
For 40 years, paleontological studies of marine gastropods have suggested that species selection favors lineages with short-lived (lecithotrophic) larvae, which are less dispersive than long-lived (planktotrophic) larvae. Although lecithotrophs appeared to speciate more often and accumulate over time in some groups, lecithotrophy also increased extinction rates, tests for state-dependent diversification were never performed. Molecular phylogenies diverse groups instead without diversifying...
