OB1 13 06 Field: Biological Sciences Author: Mr 9th SCiUS Forum Title: Biodiversity of Acorn Barnacles (Crustacea: Cirripedia) in Family Chthamalidae in Eastern Thailand OB1_13_06 Field: Biological Sciences Author: Mr. Pisit Sanjan School: Piboonbumpen Demonstration School, Burapha University Advisor: Dr. Woranop Sukparangsi Co-Advisor: Dr. Salinee Khachonpisitsak Department of Biology, Faculty of Science, Burapha University Abstract: Acorn barnacles are sessile crustacean belonging to order Sessilia Lamarck, 1818. They widely distributed in the intertidal areas of tropical and temperate regions worldwide. In previous observation, three species in Family Chthamalidae Darwin, 1854: Euraphia depressa, Euraphia hembeli, and Chthamalus malayensis have been identified along the Gulf of Thailand and Andaman Sea. However, some regions in eastern Thailand is still underinvestigated. Thus, in this study, we aimed to delineate biodiversity of chthamalids from more sampling sites along the coastline of eastern Thailand including Chanthaburi, Chon Buri, Rayong, and Trat provinces. In addition, Chthamalids exhibit diverse shell plate patterns; hence, we investigated morphological pattern of cirri, setal types and mouth parts via light microscopy in combination with scanning electron microscopy (SEM) to provide better taxonomic identification. Based upon morphological characters of parietes-operculum, ultrastructure of arthropodal characters, here we report several new records of chthamalids and highlight the diversity of barnacles in genus Chthamalus along eastern coastlines in the Gulf of Thailand. Keywords: acorn barnacles, Chthamalids, eastern Thailand, biodiversity Introduction: Rock barnacles or acorn barnacles are the sessile marine animals which belong to the Superorder Thoracica, the infraclass Cirripedia in the Crustacea. They distributed in the international areas of tropical and temperate regions worldwide. In their adult stage, they live by attaching on the rocky shore along the interdial zone and the substrates including natural substrates such as floating wood, kelps, marine veterbrate animals and artificial substrates e.g. ships, bottles, plastic bags. The family Chthamalidae in order Sessilia Lamarck, 1818 has established by Darwin (1854). In previous inspection, there are several publications about them. Chan et al. (2016) has announced 7 species of acorn barnacles in genus Chthamalus, C. anisopoma, C. fissus, C. hedgecoki, C. panamensis, C. newmani and C. alani from the north-eastern Pacific. He also documented morphological characters of shell plates, arthropodal characters and mitochondrial analysis of them. In the western Pacific, Indian ocean, Indo- Malaya, northern Australia, Vietnam, China, and Taiwan, some Chthamalus barnacles, C. chanllengeri, C. moro and C. malayensis, were reviewed by Newman & Southward (2003) and Chan et al. (2009b). Moreover, there are not only the study of Chthamalus species but acorn barnacles in the genus Euraphia, the another genus in family Chthamalidae also founded. In Thailand, Pochai et al. (2017) has noted acorn OB1_13_06/1 9th SCiUS Forum barnacles 10 species classified into 6 genera and 3 families (Balanidae, Chthamalidae and Tetraclitidae) across the Andaman sea and the Gulf of Thailand. The species in family Chthamalidae which has been reported, 2 Euraphia species, Euraphia depressa and Euraphia hembeli, and 1 Chthamalus specie, Chthamalus malayensis. Following this, in Thailand there are just 3 Chthamalid barnacles were recorded. As well as, in previous study, the taxonomic identification was only based upon the arthropodal characters using light microscope, yet there are some species which being difficult to classify by information via light microscope. Thus, our study aims to determine Chthamalid barnacles from the stations which have never been determined for new records of acorn barnacles in family Chthamalidae. Methodology: This study is based upon material collected from the Gulf of Thailand Sea in eastern Thailand, at Khao Sam Muk and Nam Nao beach, Chon Buri province, Lan Sai beach and Ratchakarun beach, Trat province and Hin Krong beach and Chao Lao beach Chathaburi province, in January 2018. Samples were collected by hand picking and were transferred in to plastic containers containing 95% ethanol. In the laboratory, These specimens were preserved in 95% ethyl alcohol and examined by using a compound microscope and stereomicroscope and later selected for dissection. All taxonomically important characters, shell plate morphology, and arthropodal characters were dissected and investigated with LEO 1450 VP scanning electron microscope on gold-coated specimens at Microscopic Center, Faculty of Science Burapha University. To identify specimens, we used keys of Chan et al. (2009) and Chan et al. (2016). The final pictures were processed with Adobe Photoshop CS6 and Adobe Illustrator CS6. Abbreviations used to denote shell morphology and arthropodal characters are explained directly in figure captions.

In addition to, previous studies that report the new records of acorn barnacles across Thailand’s coasts including the Andaman Sea and the Gulf of Thailand (Pochai et al., 2017), we also report three additional species of Chthamalus barnacles. Our study documents the taxonomic description, morphological characteristics, illustrations, systematics, and identification keys for these three species. Taking everything in consideration, this report presents the information that can enlarge the study of species distribution of acorn barnacles in Thailand. In the future, the works with more sampling sites and further in- depth investigations using molecular approaches with the help of phylogenetic analysis will provide a much better view especially of the history of barnacles and intraspecific variation between sessile crustaceans and that may inform new species from Thailand.

Abstract Inversions of the origin of replication (ORI) of mitochondrial genomes produce asymmetrical mutational pressures that can cause artefactual clustering in phylogenetic analyses. It is therefore an absolute prerequisite for all molecular evolution studies that use mitochondrial data to account for ORI events in the evolutionary history of their dataset.

Ballast water discharged from transoceanic ships is commonly believed to be the dominant pathway for species introduction and is therefore increasingly subject to domestic and international regulation. However, compared to species introductions from ballast, translocation by biofouling of ships’ exposed surfaces has been poorly quantified. We report translocation of species by a transoceanic bulk carrier intercepted in the North American Great Lakes in fall 2001. We collected 944 individuals of at least 74 distinct freshwater and marine taxa. Eight of 29 taxa identified to species have never been observed in the Great Lakes. Employing five different statistical techniques, we estimated that the biofouling community of this ship comprised from 100 to 200 species. These findings adjust upward by an order of magnitude the number of species collected from a single ship.

Of the genus Pachylasma, only two species P. crinoidophilum PrLSBRY and P.japonicum HrRo have been known from Japan. A third species P. scutistriatum BROCH is newly added to the Japanese fauna. The other known species, P. ecaudatum HrRo formerly referred to Pachylasma, is now transferred to the genus Hexelasma, of which two species H. velutinum HoEK and H. callistoderma PILSBRY only have been so far known from Japan. An attempt to subdivide the family Chthamalidae into three subfamilies (Catophragminae, Chthamalinae and Pachylasminae) is newly presented.

All rights reserved Euraphia eastropacensis (Cirripedia, Chthamaloidea), a New Species ofBarnacle from the Tropical Eastern Pacific: Morphological and Electrophoretic Comparisons with Euraphia rhizophorae (deOliveira) from the Tropical Western Atlantic and Molecular Evolutionary Implications. 1 JORGE E. LAGUNA 2 ABSTRACT: Euraphia eastropacensis sp. nov., of the tropical Eastern Pacific, is distinguished from its tropical Western Atlantic congener, E. rhizophorae , by morphological and electrophoretic evidence. Because of the apparent recent radiation of high intertidal chthamaloids and the recent closure of the Isthmus ofPanama, one would expect that these two species ofEuraphia were geminates. However, utilizing electrophoretic data, a large genetic distance value (0.95) was found, and this creates difficulties when explaining speciation between the two in terms of the molecular clock. A molecular evolutionary interpretation of the data suggests that the two species may have speciated before the closure of the Isthmus of Panama, probably as early as the Upper Miocene. THE MARINE COMMUNITIES common to the ness, and to explain the evolutionary implica­ proto-Caribbean and the tropical Eastern tions raised with respect to the molecular Pacific were separated by the tectonic closure clock hypothesis. of the Isthmus of Panama 3 million years ago .
