Ecological Status of Pirenella Cingulata (Gmelin, 1791) (Gastropod
Cibtech Journal of Zoology ISSN: 2319–3883 (Online) An Open Access, Online International Journal Available at http://www.cibtech.org/cjz.htm 2017 Vol. 6 (2) May-August, pp.10-16/Solanki et al. Research Article ECOLOGICAL STATUS OF PIRENELLA CINGULATA (GMELIN, 1791) (GASTROPOD: POTAMIDIDAE) IN MANGROVE HABITAT OF GHOGHA COAST, GULF OF KHAMBHAT, INDIA Devendra Solanki, Jignesh Kanejiya and *Bharatsinh Gohil Department of Life Sciences, Maharaja Krishnakumarsinhji Bhavnagar University, Bhavnagar 364 002 * Author for Correspondence ABSTRACT Studies on mangrove associated organisms were one of the old trends to studying mangrove ecosystems and their productivities. Seasonal status and movement of Pirenella cingulata according to habitat change studied from mangroves of Ghogha coast from December 2014 to November 2015. The maximum density (4.4/m2 area) of Pirenella cingulata reported during winter and lowest during monsoon (0.20/ m2 area). This mud snail was observed dependent on the mangrove during adverse climatic conditions during summer and monsoon seasons. Temperature and dissolved oxygen levels influence the density of P. cingulata. Keywords: Pirenella cingulata, Mangroves, Seasonal Conditions, Ghogha Coast INTRODUCTION Indo-West Pacific oceans are popular for the molluscan diversity, but despite more than two centuries of malacology, the basic knowledge about mangrove associated biota is still inadequate (Kiat, 2009). The mangroves are not only trees but itself an ecosystem comprises associated fauna, the biotope surrounded by the trees extensions like soil, stem, substrate, shade, tidal range etc., and are influential to the distribution of malacofauna (Lozouet and Plaziat, 2008). Indian coastline comprises three gulfs, namely Gulf of Kachchh and Gulf of Khambhat in west site while Gulf of Mannar in southeast side. -

Bulletin of the British Museum (Natural History)
Charixa Lang and Spinicharixa gen. nov., cheilostome bryozoans from the Lower Cretaceous P. D. Taylor Department of Palaeontology, British Museum (Natural History), Cromwell Road, London SW7 5BD Synopsis Seven species of non-ovicellate anascans with pluriserial to loosely multiserial colonies are described from the Barremian-Albian of Europe and Africa. The genus Charixa Lang is revised and the following species assigned: C. vennensis Lang from the U. Albian Cowstones of Dorset, C. Ihuydi (Pitt) from the U. Aptian Faringdon Sponge Gravel of Oxfordshire, C. cryptocauda sp. nov. from the Albian Mzinene Fm. of Zululand, C. lindiensis sp. nov. from the Aptian of Tanzania, and C.I sp. from the Barremian Makatini Fm. of Zululand. Spinicharixa gen. nov. is introduced for Charixa-\ike species with multiple spine bases. Two species are described: S. pitti sp. nov., the type species, probably from the Urgoniana Fm. (?Aptian) of Spain, and S. dimorpha from the M.-U. Albian Gault Clay of Kent. All previous records of L. Cretaceous cheilostomes are reviewed. Although attaining a wide geographical distribution, cheilostomes remained uncommon, morphologically conservative and of low species diversity until late Albian-early Cenomanian times. Introduction An outstanding event in the fossil history of the Bryozoa is the appearance, radiation and dominance achieved by the Cheilostomata during the latter part of the Mesozoic. Aspects of et al. this event have been discussed by several authors (e.g. Cheetham & Cook in Boardman 1983; Larwood 1979; Larwood & Taylor 1981; Schopf 1977; Taylor 1981o; Voigt 1981). Comparative morphology provides strong evidence for regarding living cheilostomes as the sister group of living ctenostome bryozoans (Cheetham & Cook in Boardman et al. -
참서대과 (Pisces: Cynoglossidae) 자어 2종의 미토콘드리아 DNA에 의한 형태동정의 타당성
Kor J Fish Aquat Sci 43(5), 482-488 한수지, 43(5), 482-488, 2010 참서대과 (Pisces: Cynoglossidae) 자어 2종의 미토콘드리아 DNA에 의한 형태동정의 타당성 권혁준・김진구✽ 부경대학교 자원생물학과 Validation of Morphology-based Identification of Two Cynoglossidae Larvae using Mitochondrial DNA Hyuck Joon Kwun and Jin Koo Kim* Department of Marine Biology, Pukyong National University, Busan 608-737, Korea Three specimens of Cynoglossidae larvae were collected from the southern Korean Sea in May and August of 2009, and were identified using morphological and molecular analysis. Specimens were divided into two groups based on the number of elongated dorsal fin rays on the top of the head: Cynoglossidae sp. A was defined as having two elongated dorsal fin rays, while Cynoglossidae sp. B possessed a single elongated dorsal fin ray. One specimen of Cynoglossidae sp. A, a post-larva with a notochord length (NL) of 5.8 mm was thought to be a Cynoglossus joyneri larva based on the presence of 115 dorsal pterogiophores, 85 anal pterogiophores, and 50 myomeres. Two specimens of Cynoglossidae sp. B, a 4.1 mm NL larva and a 11.3 mm NL juvenile, were thought to be Cynoglossus abbreviatus based on the presence of yolk in the former and 133 dorsal fin rays, 105 anal fin rays, and 63 myomeres in the latter. To test this morphology-based identification, molecular analysis was conducted using 419-422 bp of mitochondrial DNA 16S rRNA. Cynoglossidae sp. A was clearly matched to a Cynoglossus joyneri adult (d=0.000) and Cynoglossidae sp. B clustered closely with Cynoglossus abbreviatus adults (d=0.002). -
A Close-Up View on ITS2 Evolution and Speciation
Caisová et al. BMC Evolutionary Biology 2011, 11:262 http://www.biomedcentral.com/1471-2148/11/262 RESEARCH ARTICLE Open Access A close-up view on ITS2 evolution and speciation - a case study in the Ulvophyceae (Chlorophyta, Viridiplantae) Lenka Caisová1,2,3*†, Birger Marin1† and Michael Melkonian1 Abstract Background: The second Internal Transcriber Spacer (ITS2) is a fast evolving part of the nuclear-encoded rRNA operon located between the 5.8S and 28S rRNA genes. Based on crossing experiments it has been proposed that even a single Compensatory Base Change (CBC) in helices 2 and 3 of the ITS2 indicates sexual incompatibility and thus separates biological species. Taxa without any CBC in these ITS2 regions were designated as a ‘CBC clade’. However, in depth comparative analyses of ITS2 secondary structures, ITS2 phylogeny, the origin of CBCs, and their relationship to biological species have rarely been performed. To gain ‘close-up’ insights into ITS2 evolution, (1) 86 sequences of ITS2 including secondary structures have been investigated in the green algal order Ulvales (Chlorophyta, Viridiplantae), (2) after recording all existing substitutions, CBCs and hemi-CBCs (hCBCs) were mapped upon the ITS2 phylogeny, rather than merely comparing ITS2 characters among pairs of taxa, and (3) the relation between CBCs, hCBCs, CBC clades, and the taxonomic level of organisms was investigated in detail. Results: High sequence and length conservation allowed the generation of an ITS2 consensus secondary structure, and introduction of a novel numbering system of ITS2 nucleotides and base pairs. Alignments and analyses were based on this structural information, leading to the following results: (1) in the Ulvales, the presence of a CBC is not linked to any particular taxonomic level, (2) most CBC ‘clades’ sensu Coleman are paraphyletic, and should rather be termed CBC grades. -

Compared to other phyla, little is known about their phylogenetic relationships at both lower and higher taxonomic levels. Hence, an effort is being made to elucidate their phylogenetic relationships. Here, we present newly sequenced nuclear and mitochondrial genes for 21 cheilostome bryozoans. Combining these data with existing orthologous molecular data, we focus on reconstructing the phylogenetic relationships of Fenestrulina and Microporella, two species-rich genera. They are currently placed in Microporellidae, defined by having a semicircular primary orifice and a proximal ascopore. -

The Status of Mariculture in North China
The Status of Mariculture in North China Chang Yaqing1,Chen Jiaxin2 (1.Key Lab of Mariculture and Biotechnology.Dalian Fisheries University,Dalian, Liaoning, 116023, P.R China;2.Yellow Sea Fisheries Research Institute Chinese Academy of Fisheries Sciences, Qingdao, Shandong,266071, P.R China) Introduction China has a long history of mariculture production. The mariculture industry in China has obtained break through in the all artificial nursery and cultural technique of shrimps, mollusca and fishes of high commercial value since 1950s, which has advanced the development of mariculture industry. The first major development was seaweed culture during 1950s, prompted by breakthroughs in breeding technology. By the end of the 1970s, annual seaweed production reached 250,000 metric tons in dry weight ( approximately 1.5million tons of fresh seaweed ). Shrimp culture developed during the 1980s because of advances in hatchery technology and economic reform policies. Annual shrimp production reached 210,000 tons in 1992. Disease outbreaks since 1993, however, have reduced shrimp production by about two-thirds. Mariculture production increased steadily between 1954 and 1985, but has been exponential since 1986, mostly driven by molluscan culture. Molluscan 1 culture in China began to expand beyond the four traditional species: oyster,cockle,razor clam and ruditapes clam in the 1970s,Mussel culture was the first new industry to emerge ,followed by scallop aquaculture in 1980s. Abalone culture has become a major industry in 1990s. Traditional oyster and clam cultures have also advanced and expanded in recent years.Now more than 30 species of marine mollusks are cultured commercially in China. Because of the rapid development in recent years, molluscan culture has become the largest sector of the Chinese mariculture industry, accounting for 81% of the total production in weight. -

Checklist of the Cerambycidae, Or Longhorned Beetles (Coleoptera) of the Western Hemisphere 2009 Version (Updated Through 31 December 2008) Miguel A
1 Checklist of the Cerambycidae, or longhorned beetles (Coleoptera) of the Western Hemisphere 2009 Version (updated through 31 December 2008) Miguel A. Monné, and Larry G. Bezark, Compilers Introduction The Cerambycidae, commonly known as longhorned beetles, longicorns, capricorns, round-headed borers, timber beetles, goat beetles (bock-käfern), or sawyer beetles, comprise one of the largest and most varied families of Coleoptera, with body length alone varying from ± 2.5 mm (Cyrtinus sp.) to slightly over 17 cm (Titanus giganteus). Distributed world- wide from sea level to montane sites as high as 4,200 m elevation wherever their host plants are found, cerambycids have long been a favorite with collectors. Taxonomic interest in the family has been fairly consistent for the past century, but the description of new taxa has accelerated in recent decades thanks to the efforts of Chemsak, Linsley, Giesbert, Martins, Monné, Galileo, Napp, and other workers. This checklist builds upon the efforts of Blackwelder (1946), Chemsak & Linsley (1982), Chemsak, Linsley & Noguera (1992), and Monné & Giesbert (1994), and presently includes nearly 9,000 described species and subspecies, covering the terrestrial hemisphere from Canada and Alaska to Argentina and Chile, and including the Caribbean arc. Adult Cerambycidae, upon which most taxonomic studies in the family have been based, vary widely in their habits. Some species are nocturnal, many are attracted to artificial light, and they also may be found at night on the trunks and branches of their host plants, or on foliage. Diurnal species also may be found on or near their host plants, but many species are attracted to blossoms of shrubs and trees, where they may serve as pollinators.
