Based on molecular data three major clades have been recognized within Bilateria: Deuterostomia, Ecdysozoa, and Spiralia. Within Spiralia, small-sized simply organized animals such as flatworms, gastrotrichs, gnathostomulids recently grouped together Platyzoa. However, the representation of putative platyzoans was low in respective phylogenetic studies, terms both, taxon number sequence data. Furthermore, increased substitution rates platyzoan taxa raised possibility that monophyletic...
Abstract Although sexual reproduction is ubiquitous throughout nature, the molecular machinery behind it has been repeatedly disrupted during evolution, leading to emergence of asexual lineages in all eukaryotic phyla. Despite intensive research, little known about what causes switch from asexuality. Interspecific hybridization one candidate explanations, but reasons for apparent association between and asexuality remain unclear. In this study, we combined cross‐breeding experiments with...
Despite recent great interest in glacier ecosystems the continental Antarctic, little is known about their maritime counterparts. Our study presents descriptive data on cryoconite sediments and holes Ecology Glacier (King George Island) to accomplish three main objectives: (a) identify eukaryotic (algae, invertebrates) prokaryotic (cyanobacteria) components of microbial communities; (b) provide a "baseline" community composition, organic matter artificial contamination; (c) key abiotic...
Abstract Despite its inherent costs, sexual reproduction is ubiquitous in nature, and the mechanisms to protect it from a competitive displacement by asexuality remain unclear. Popular mutation‐based explanations, like Muller's ratchet Kondrashov's hatchet, assume that purifying selection may not halt accumulation of deleterious mutations nonrecombining genomes, ultimately leading their degeneration. However, empirical evidence scarce remains particularly unclear whether mutational...
Abstract Aim The long history of isolation the Antarctic continent, coupled with harsh ecological conditions freezing temperatures, could affect patterns genetic diversity in organisms living there. We aim (a) to test whether such pattern can be seen a mitochondrial marker bdelloid rotifers, group microscopic aquatic and limno‐terrestrial animals (b) speculate on potential mechanisms driving pattern. Location Focus Antarctica. Taxon Rotifera Bdelloidea. Methods analysed different metrics...
We present a data set on Antarctic biodiversity for the phylum Rotifera, making it publicly available through Biodiversity Information facility. provide taxonomic information, geographic distribution, location, and habitat each record. The gathers all published literature about rotifers found identified across Continental, Maritime, Subantarctic biogeographic regions of Antarctica. A total 1455 records in Antarctica from 1907 to 2018 is reported, with information hierarchies, updated...
We present a morphological feature-based key for the genus Otostephanos and describe two new species, O. jolantae sp. nov. ukrainicus For we analysed intraspecific variability provided barcodes of mtCOX1 mitochondrial gene. Further, developed method to standardize measurements Philodina type corona trophi bdelloids. is large rotifer with smooth cuticle bright red-orange gut; it can be distinguished from known species by high triangular upper lip tongue-like tip not divided into lobes,...
This work contributes to the knowledge on distribution, diversity and ecology of Antarctic soil biota. Different habitats from several ice-free coastal sites were sampled along Victoria Land across 7° latitude 71° 78°S during five austral summer seasons between 2003/04 2011/12. In this paper we report preliminary data tardigrades (water bears) Edmondson Point, Northern Land. Tardigrades found be present in 23 41 examined samples (56%). Their presence was associated exclusively with collected...
Bdelloid rotifers are a group of microscopic invertebrates known for their obligate parthenogenesis and exceptional resistance to extreme environments. Their diversity distributions poorly studied in Asia, especially China. In order better understand the species distribution bdelloid China, scientific surveys habitats was conducted with 61 samples (both terrestrial aquatic habitats) from 11 provinces regions ranging tropics subtropics specific focus on sampled areas (Oriental) during...
A complete checklist of invertebrates inhabiting terrestrial moss communities the Petermann Island and adjacent region Antarctic Penninsula is published for first time. We investigated materials collected by two coauthors performed comprehensive analysis sources on species composition nematodes, rotifers, springtails, insects, mites tardigrades. In ecosystems Islands found 28 invertebrates, with dominating (11 species) rotifers (8 species). total, 67 invertebrate are known, nematodes (28...
Abstract Interactions between a host organism and its associated microbiota, including symbiotic bacteria, play crucial role in adaptation to changing environmental conditions. Antarctica provides unique environment for the establishment maintenance of relationships. One most extensively studied bacteria invertebrates is Wolbachia pipientis , which with wide variety invertebrates. known manipulating reproduction having obligate or facultative mutualistic relationships various hosts. However,...
Despite only 0.3% of Antarctica being ice-free, those areas harbor diverse small organisms such as tardigrades, nematodes, and rotifers. The habitats these cryptic face threats from human activity, climate change, pollution. Biodiversity surveys are essential for managing their protection have been proven well possible in using environmental DNA (eDNA) analysis. Early eDNA research had greatly benefited high-throughput sequencing the now obsolete 454 pyrosequencing technique, which at time...
Abstract Speciation usually proceeds in a continuum from intensively hybridizing populations until the formation of irreversibly isolated species. Restriction interspecific gene flow may often be achieved by gradual accumulation intrinsic postzygotic incompatibilities with hybrid infertility typically evolving more rapidly than inviability. A reconstructed history speciation European loaches (Cobitis) reveals that reproductive take an alternative, literature largely neglected, pathway...
