A new species of protosquillid mantis shrimp is described from the coastal waters Korea and Japan. Chorisquilla orientalis n. sp. distinguished congeners by combination deep grooves pits on dorsal surface abdominal somite 5, 8–14 spines lateral margin telson, numerous minute telson 6, large, pyriform submedian bosses preceded a small rounded boss. morphologically closest to C. mehtae Erdmann & Manning, 1998, Indonesia, but differs chiefly in ornamentation 6 reaches considerably larger...
The palaemonid genus Isopericlimenaeus is currently comprised of only the type species, gorgonidarum, with diagnostic character being presence a molar and fossa structure on both second chelipeds. Periclimenaeus uropodialis closely related which has either been considered synonym I. gorgonidarum or placed as valid species in genus, Periclimenaeus. During fieldwork Philippines, Taiwan Korea, several other sponge associated shrimps belonging to family Palaemonidae were collected, including P....
We report the discovery of a new species genus Pycnogonum Brünnich, 1764 found in shallow waters Green Island, Taiwan. (Nulloviger) granulatum sp. nov. is characterized by presence granular integument, dorsal tubercle on proboscis, transverse ridges surface trunk, and spines ventral tibia, tarsus, propodus having cleft tips. Because male gonopores are present ovigers absent, belongs to subgenus Nulloviger. The has been compared with P. (N.) moolenbeeki Stock, 1992, lobipes 1991, tuberculatum...
A new benthic isopod species, Arcturina serrulatus sp. nov. (Arcturidae Dana, 1849), is described from South Korea. Additionally, we report Limnoria rhombipunctata Yoshino, Watabe & Ohsawa, 2017 (Limnoriidae White, 1850) the rhizome of Zostera (seagrass). These are first records species belonging to families Arcturidae and Limnoriidae We provide detailed descriptions diagnostic characters two species. also determined their partial sequences mitochondrial cytochrome c oxidase subunit 1...
The present study describes a new species of Pyrgoma Leach, 1817, coral associated barnacle attached to Tubastrea, from the south New Caledonia. spurtruncata sp. nov. is morphologically close P. cancellatum 1818, japonica Weltner, 1897 and kuri Hoek, 1913 in absence extended tergal muscle crests. have shallow, fully open, medial furrow spur, whereas deeper closed. differs width spur length rostral tooth scutum. Phylogenetic analyses based on two mitochondrial markers, 12S rDNA COI, confirm...
Nucleotide sequences from the 18S subunit of ribosomal RNA were determined for 9 species decapod crustaceans: 1 suborder Dendrobranchiata (Penaeus aztecus) and 8 Pleocyemata, representing 4 different infraorders (Procaris ascensionis Palaemonetes kadiakensis, Caridea; Stenopus hispidus, Stenopodidea; Procambarus leonensis, P. paeninsulanus, youngi, Astacidea; Callinectes sapidus, Brachyura). The total aligned set nucleotides consisted ranging in length 869-1721 bases. Comparison among...
Recent progress in molecular techniques has generated a wealth of information for phylogenetic analysis. Among metazoans all but single phylum have been incorporated into some sort However, the minute and rare species Loricifera remained elusive to systematists. Here we report first sequence data (nearly complete 18S rRNA) member Loricifera, Pliciloricus sp. from Korea. The new were analyzed together with 52 other ecdysozoan sequences, phyla represented by three or more sequences. set was...
Abstract The coastline of the Korean Peninsula is influenced by three major oceanographic ecoregions, including estuarine Yellow Sea ecoregion on west coast, warmer and saline East China south cold east coast. influence these marine ecoregions distribution intertidal barnacles has not been extensively studied. present study examines biogeography thoracican from shallow subtidal zones, along coasts Korea. Twenty-one species in seven families were identified, coral-associated barnacles....
DNA barcoding provides a rapid, accurate, and standardized method for species-level identification using short sequences. Such is useful mapping all the species on Earth, particularly when sequencing technology cheaply available. There are many nations in Asia with biodiversity resources that need to be mapped registered databases.We have built general barcode data processing system, BioBarcode, open source software - which purpose database server. It uses mySQL RDBMS 5.0, BLAST2, Apache...
Abstract Manning's roughness coefficient was estimated for a gravel-bed river reach using field measurements of water level and discharge, the applicability various methods used estimation evaluated. Results show that tends to decrease with increasing discharge depth, over certain range it appears remain constant. Comparison coefficients calculated by measurement data those other shows that, although field-measured values provide approximate relatively large there seems be rather high...
Non-biting midges (Diptera: Chironomidae) are a diverse population that commonly causes respiratory allergies in humans. Chironomid larvae can be used to indicate freshwater pollution, but accurate identification on the basis of morphological characteristics is difficult. In this study, we constructed mitochondrial cytochrome c oxidase subunit I (COI)-based DNA barcode library for Korean chironomids. This consists 211 specimens from 49 species, including adults and unidentified larvae. The...
In this study, the species composition and population genetic properties of sea slater, Ligia, in South Korea were investigated using mitochondrial nuclear gene sequences. Two groups slaters, genetically isolated from each other, a Western Group (WG) an Eastern (EG) identified. These exhibited considerable divergence Ligia exotica, previously recorded as inhabiting country. results indicate that there may be two Korea, but is small probability both are L. exotica. A comparison their...
We compared primary and secondary structures of V4 (helices E23-2 to E23-5) V7 (helix 43) regions 18S rRNAs in insects the other three major arthropod groups (crustaceans, myriapods, chelicerates) known so far. found that lengths sequences shapes these two hypervariable insect rRNA even at infraclass levels are phylogenetically informative reflect steps evolution. The long sequence insertion bifurcated shape helices E23-5 region unique synapomorphic characters for winged (Pterygota)....
A taxonomic study was carried out on the Perinereis nuntia species group of Korea by using morphological and molecular data (mitochondrial cytochrome c oxidase subunit I: mtCOI). Two species, P. mictodonta (Marenzeller, 1879) wilsoni (Glasby Hsieh, 2006), are recognized redescribed. In this study, mtCOI gene showed a good resolution as marker for identification Korea.
We performed a diversity study on parasitic barnacles (Crustacea: Cirripedia: Rhizocephala: Peltogastridae) that parasitize hermit crabs in Korea. Their morphological, ecological, molecular (cytochrome c oxidase subunit I, 16S rRNA), and biogeographical characteristics were examined. Three species identified based GenBank sequences the external morphology of externa. In addition, this proposes four new candidate species. This is first report family Peltogastridae from Six crab found to be...
Abstract Whale-associated barnacles are intriguing in terms of their planktonic food sources, mating habits, and mechanisms host attachment. We present observations the whale-associated Coronula diadema (Linnaeus, 1767) Conchoderma auritum obtained from dead humpback whales (Megaptera novaeangliae (Borowski, 1781)) collected Korea. Shell bases inflected sharp-edged with hollow coring tubes at periphery. The filled whale skin, supporting model that shell accretion into skin is achieved by...
The Bering Strait is the only gateway to Chukchi Sea from Pacific Ocean and a major route of water inflow. We recently investigated occurrence copepod species along with warming sought identify cause mass these copepods through an analysis masses flowing Strait. Zooplankton Conductivity-Temperature-Depth (CTD) data collection was conducted in 2014 2016.

Despite that the exotic invasion and rapid range expansion of Asian freshwater Corbicula into new environments have been intensive research topic in ecology, genetic structures its native remain poorly understood. In this study, two Korean clonal lineages were characterized by cross-referencing nuclear genomic with mtDNA sequence analysis. spite substantial differences (Nei’s D = 0.363−0.372) a pronounced level fixed allelic distinctions (in six 20 allozyme loci) between lineages, no...
