The disease of freshwater sponges was first discovered in 2011, when pink samples were found the Central Basin Lake Baikal. Subsequently, visible signs have changed, and now appear with various symptoms damage to body, such as discoloration, tissue necrosis, formation brown patches dirty-purple biofilms on some branches. These are accompanied by mass death sponges. We identified differences microbiomes sequencing 16S rRNA genes changes consortium microorganisms Baikal that observed imbalance...
Sponges are an ecologically important component of marine and freshwater bodies. Sponge community includes a variety microorganisms: fungi, algae, archaea, bacteria viruses. Despite active research in the field aquatic virology, biodiversity role viruses sponges poorly studied. The relevance this area is also related to worldwide problem sponge diseases. aim study was elucidate genetic diversity associated diseased endemic Baikal Lubomirskia baikalensis using metagenomic analysis. As result,...
This paper reports on a new species of the Baikal endemic sponge (fam. Lubomirskiidae) Swartschewskia khanaevi sp. nov. The description this is based morphological and molecular data (ITS mitochondrial IGRs). Morphologically, S. differs from papyracea by loose tracts arranged in an irregular network as well presence strongyles compound spines looking like tubercles densely ornamented with simple spines. Moreover, specimens show peculiar structure aquiferous system at body surface that may be...
Complete and nearly complete mtDNA genome sequences were used to resolve differences between two palaeontology-based hypotheses on timing of the origin Baikal endemic sponge family Lubomirskiidae (Haplosclerida, Demospongiae). Bayesian ratio test, when coupled with estimates substitution rates based known palaeontological findings, provided strong evidence for Miocene over Late Oligocene one. The common ancestor present day sponges in Lake diverged about 2,3 million years ago (Ma), while...
In recent years, signifcant changes in the ecological system of coastal (littoral) zone, including mass death endemic representatives freshwater sponges Lubomirskiidae family, have been an urgent problem Lake Baikal. Similar problems are known all over world. Thus, disease and corals indicated Mediterranean, Adriatic, Caribbean other seas, which raises serious concerns about future these biocenoses (Olson et al., 2006; Webster, 2007; Wulff Stabili 2012). Baikal, diseased were frst found...
Sponges are ecologically important components of marine and freshwater benthic environments; these holobionts contain a variety microorganisms viruses. For the metagenomic characterization potential taxonomic functional diversity sponge-associated dsDNA viruses, we surveyed two samples Baikal endemic sponge Baikalospongia bacillifera (diseased visually healthy). In total, after quality processing, have obtained 3 375 063 4 311 reads; 97 557 88 517 sequences, accounting for ca. 2.9 2.2%...
Abstract This article presents the results of observations state Baikal endemic sponge fauna (Fam. Lubomirskiidae) in five-year dynamics against background their mass mortality. We indicate change projective bottom cover with healthy and diseased sponges at two sites that are radically different from each other level anthropogenic pressure. also analyse types diseases species exposed to these study sites. observe a significant decrease area both site experiencing heavy pressure where it is...
Within the framework of monitoring Baikal endemic sponge fauna, which was started in 2015, we organized field observations. This study is aimed to investigate dynamics disease incidence sponges and rate their degradation/regeneration natural environment within a limited space. The observations tagged having different shapes were carried out using photo video method. Thus, from 2016 2018, there deterioration state most control sponges. From 2018 2019, some improved owing regeneration affected...
The complete mitochondrial genome of the Lake Baikal sponge Baikalospongia intermedia was sequenced. circular is 28,327 bp in length and includes 14 protein-coding genes, 2 ribosomal RNA genes 25 transfer genes. Bayesian comparative analysis molecular evolution rates found no acceleration mtDNA B. intermedia. This species clustered with other genus on tree.
Sponges are unusual representatives of the animal kingdom; their viromes, as part associated community, began to be studied quite recently, and, accordingly, these studies gaining momentum. The diversity viruses in sponges is high, and they most likely play a significant role composition sponge holobiont, especially under stress conditions. objects our metagenomic study were RNA two common endemic species Baikal sponges, Lubomirskia baikalensis Baikalospongia bacillifera. As result viral...
Lake Baikal and its invertebrates became a subject of systematic evolutionary studies more than century ago. Exceptional taxonomic diversity the lake’s fauna, high variability habitats large volume auxiliary knowledge on ecosystem enables one to study fine details speciation mechanisms hardly accessible in other model systems. Parallel development technological methodological potential biology most new approaches were employed Baikal. This review deals mostly with results obtained during...
