Stony Alveopora japonica coral, Alveopora japonica, is observed more frequently for the last few years in temperate sea like Jeju Island, Coral South Korea. To understand the ecological consequences such as habitat formation and fate of this species in Holobiont changing environment, unraveling the genetic makeup of the species is essential. We sequenced the tran- Transcriptome scriptome of the A. japonica holobionts using Illumina HiSeq2000 platform. De novo assembly and analysis of Climate change coding regions predicted 108,636 coding sequences consisted of the coral host and residing Symbiodinium. Homology analysis showed the gene contents from our assembly are comparable to other sequenced corals and Symbiodiniums. The reference assembly of A. japonica will be a valuable resource to study the ecological characteristics of this species in the marine benthic ecosystem. 1. Introduction temperate region of Japan. The KC is experiencing a rapid increase in seawater temperature in response to global climate change and warmed The colonial stony coral Alveopora japonica is a zooxanthellate most rapidly from 1981 to 1998, when the surface temperatures rose by scleractinian coral in the family Acroporidae (WoRMS, n.d.).

  • CNIDARIA Corals, Medusae, Hydroids, Myxozoans
    FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.

Corals include 25 species, derived from 15 different genera and 12 families. Six of 26 them remain with open nomenclature. From the 25 species found in the study area, 88% are 27 extinct and the remaining under endanger status. Most of the species are hermatypic components 28 of the Scleractinian order, with the exception of a member of the Milleporidae family. The corals 29 described are composed of typical taxa from the Oligocene-Miocene transition, during which 30 they were important components in building fringing and patch reefs in the circum- 31 Caribbean/Gulf of Mexico region.

  • Phylogenetic and Taxonomic Status of the Coral
    Kitano et al. Zoological Studies 2013, 52:25 http://www.zoologicalstudies.com/content/52/1/25 RESEARCH Open Access Phylogenetic and taxonomic status of the coral Goniopora stokesi and related species (Scleractinia: Poritidae) in Japan based on molecular and morphological data Yuko F Kitano1, Masami Obuchi2, Daisuke Uyeno3, Katsumi Miyazaki1 and Hironobu Fukami4* Abstract Background: Goniopora stokesi is an uncommon species mainly found in tropical and subtropical regions but was also reported in temperate regions of Japan. This species has two unique characteristics. First, it does not typically attach to hard substrates, i.e., it is free-living. Although non-free-living colonies were reported, it is unclear whether their morphologies exhibit intraspecific or interspecific differences. Second, they can asexually form daughter colonies, which are secondary colonies that grow on the surface (coenosac) of a parent colony and subsequently detach. To date, this specific characteristic has not been reported in Japan, and it is not clear whether this species occurs in Japan. Results: To clarify the taxonomic status of this species, we investigated its reproductive mechanism in Japan and morphologically and genetically analyzed specimens collected from both subtropical and temperate regions. We found that this species forms daughter colonies in Okinawa, Japan and that free-living colonies in the temperate region, which were formerly recognized as G. stokesi, likely constitute a morphological variation of a separate species. In addition, all non-free-living colonies with G. stokesi-like morphologies were also morphological variations of other species. Conclusions: Overall, free-living colonies with large, deep calices, thin walls, and well-developed epitheca on the underside were G.
