Abstract Sponges (phylum Porifera) are early-diverging metazoa renowned for establishing complex microbial symbioses. Here we present a global Porifera microbiome survey, set out to establish the ecological and evolutionary drivers of these host–microbe interactions. We show that sponges reservoir exceptional diversity major contributors total world’s oceans. Little commonality in species composition or structure is evident across phylum, although symbiont communities characterized by...
The dichotomy between high microbial abundance (HMA) and low (LMA) sponges has been long recognized. In the present study, 56 sponge species from three geographic regions (greater Caribbean, Mediterranean, Red Sea) were investigated by transmission electron microscopy for presence of microorganisms in mesohyl matrix. Additionally, bacterial enumeration DAPI-counting was performed on a subset samples. Of investigated, 28 identified as belonging to HMA LMA category. orders Agelasida Verongida...
A new species of Raspailia (Raspaxilla) frondosa sp. nov. is described from the deep seamounts Norfolk and New Caledonia Ridges. The morphology resembles that a frond or fern, its unique highly compressed axial skeleton interlaced spongin fibres without spicules in combination with radial extra perpendicular palisade spicules, differentiate it all other subgenus. This compared morphologically to 18 valid (Raspaxilla).
This research presents 17 new species of carnivorous sponges from the family Cladorhizidae sampled at bathyal and abyssal depths off east coast Australia during RV Investigator 2017 Abyss Expedition. The are comprised six genera: Abyssocladia escheri sp. nov., A. annae gliscofila Asbestopluma (Asbestopluma) maxisigma Cladorhiza australis nov. sp., C. poritea investigator moniqueae pentaeiros Chondrocladia (Chondrocladia) freycinetensis Ch. (Ch.) callistemonex zygainadentonis Lycopodina...
Margaritifera margaritifera and M. auricularia are among the most endangered freshwater mussels in world, only species of genus found Europe. Our genetic study explores allozymic variability (27 loci) differentiation at mitochondrial sequence level (partial COI 16S rRNA gene sequences). The Spanish population showed parameters variation that were same order as those other molluscs (though lower end range), probably permitting its potential recovery. difference between this was clearly...
Abstract Partitions of the cytochrome oxidase subunit 1 ( CO1 ) gene, especially 5′ end, are frequently recruited to infer lower level phylogenies in animals. In diploblasts, mitochondrial genes were found evolve a slower rate than their bilaterian counterparts. Therefore, diploblast gene trees repeatedly remained unresolved, which also raises doubts on suitability for DNA barcoding these The complete genome sequences from Anthozoa and recently Porifera allow us compare resolution power...
Phylum Porifera includes ∼8,500 valid species distributed world-wide in aquatic ecosystems ranging from ephemeral fresh-water bodies to coastal environments and the deep-sea. The taxonomy systematics of sponges is complicated, morphological identification can be both time consuming erroneous due phenotypic convergence secondary losses, etc. DNA barcoding provide sponge biologists with a simple rapid method for samples unknown taxonomic membership. Sponge Barcoding Project...
Unique samples of deep-water sponges Lake Baikal were collected between 120 and 1450 m depth their taxonomy bathymetric distribution studied. Based on morphological studies with scanning electron microscopy (SEM) molecular analyses (CO1, ITS) we describe a new species, Baikalospongia abyssalis sp. nov. Spicule morphology this species is similar to Palaeoephydatia sp., previously known only from fossils in Late Pliocene (3.2−2.8 mya) sediments. Other sponge identified as intermedia...
During a scientific expedition to the Palinurus Rock, Persian Gulf, Iraq, reef, which was discovered first in 2012, we found new species tentatively assigned Ciocalypta (Porifera, Demospongiae, Suberitida, Halichondriidae). Genetic results from different authors (Morrow Cardenas, 2015, Redmond et al., 2013, Erpenbeck 2012) suggest that several of and other Suberitida (e.g. Axinyssa, Petromica, Topsentia, Cymbastela, Halichondria (Eumastia)) are indeed no but belong taxa yet unnamed. The...
Approximately 80% of all described extant sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades. The estimation time is key answering fundamental questions on origin Demospongiae, diversification historical biogeography. Molecular sequence data alone not informative an absolute scale, therefore needs be "calibrated" with additional such as fossils. Here, we calibrate molecular...
In the present study, we profiled bacterial and archaeal communities from thirteen phylogenetically diverse deep-sea sponge species (Demospongiae Hexactinellida) South Pacific by 16S rRNA-gene amplicon sequencing. Additionally, associated bacteria archaea were quantified real-time qPCR. Our results show that sponges are mostly host-species specific similar to what has been observed for shallow-water demosponges. The community structures different in they almost completely dominated a single...
The complete mitochondrial genomes of two reptiles, the common iguana (Iguana iguana) and caiman (Caiman crocodylus), were sequenced in order to investigate phylogenetic questions tetrapod evolution. addition species allows analysis reptilian relationships using data sets other than those including only fast-evolving species. crocodilian seem have evolved generally at a higher rate vertebrates. Phylogenetic analyses 2889 amino-acid sites from 35 supported bird-crocodile relationship, lending...
In the past decade molecular genetic markers have been introduced for research on evolution and systematics of sponges. Historically, sponges difficult to classify due lack complex characters with result that hypothesised phylogenetic relationships various sponge taxa changed rapidly over few years. Here, we summarize current status systematic hypotheses proposed We discuss among three classes, Calcarea (calcareous sponges), Hexactinellida (glass sponges) Demospongiae, as well those members...
Background DNA barcoding is a promising tool to facilitate rapid and unambiguous identification of sponge species. Demosponges the order Dictyoceratida are particularly challenging identify, but ecological as well biochemical importance. Methodology/Principal Findings Here we apply with standard CO1-barcoding marker on selected Indo-Pacific specimens two genera, Ircinia Psammocinia family Irciniidae. We show that CO1 identifies several species new science, reveals separate radiation patterns...
Background The classification of gobioid fishes is still under discussion. Several lineages, including the Eleotridae and Butidae, remain difficult to characterize because synapomorphies are rare (Eleotridae) or have not yet been determined (Butidae). Moreover, fossil record these groups scarce. Results Exceptionally well-preserved fish fossils with otoliths in situ from uppermost Oligocene sediments (≈23–24 Mio. y. ago) Southern France provide most in-depth description a date. species was...
Abstract Porifera are a diverse animal phylum with species performing important ecological roles in aquatic ecosystems, and have become models for multicellularity early-animal evolution. Demosponges form the largest class sponges, but previous studies relied on only draft demosponge genome of Amphimedon queenslandica . Here we present 125-megabase contractile laboratory Tethya wilhelma , sequenced to almost 150x coverage. We explore genetic repertoire transporters, receptors,...
