  • Analysis of Synonymous Codon Usage Patterns in Sixty-Four Different Bivalve Species
    Analysis of synonymous codon usage patterns in sixty-four diVerent bivalve species Marco Gerdol1, Gianluca De Moro1, Paola Venier2 and Alberto Pallavicini1 1 Department of Life Sciences, University of Trieste, Trieste, Italy 2 Department of Biology, University of Padova, Padova, Italy ABSTRACT Synonymous codon usage bias (CUB) is a defined as the non-random usage of codons encoding the same amino acid across diVerent genomes. This phenomenon is common to all organisms and the real weight of the many factors involved in its shaping still remains to be fully determined. So far, relatively little attention has been put in the analysis of CUB in bivalve mollusks due to the limited genomic data available. Taking advantage of the massive sequence data generated from next generation sequencing projects, we explored codon preferences in 64 diVerent species pertaining to the six major evolutionary lineages in Bivalvia. We detected remarkable diVerences across species, which are only partially dependent on phylogeny. While the intensity of CUB is mild in most organisms, a heterogeneous group of species (including Arcida and Mytilida, among the others) display higher bias and a strong preference for AT-ending codons. We show that the relative strength and direction of mutational bias, selection for translational eYciency and for translational accuracy contribute to the establishment of synonymous codon usage in bivalves. Although many aspects underlying bivalve CUB still remain obscure, we provide for the first time an overview of this phenomenon

  • New Report and Taxonomic Comparison of Anadara and Tegillarca Species of Arcidae (Bivalvia: Arcoidea) from Southern Coast of India
    International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 New Report and Taxonomic Comparison of Anadara and Tegillarca Species of Arcidae (Bivalvia: Arcoidea) from Southern Coast of India Souji.S1, Tresa Radhakrishnan2 Department of Aquatic Biology and Fisheries, University of Kerala, Thiruvananthapuram-695 581, Kariyavattom, Kerala, India Abstract: Arcacea family is economically important group of animals. Most of the species in this family are misplaced into invalid subgenera and Indian arcids are wanted a revision in systematic positon. In the case of Arcidae family; all of the species are treated under Anadara as main genera, however, some authors considered that the Tegillarca genus is only a sub genus of Arcidae family. Anadara is the commercially important genus of bivalves of Arcidae family. These two genera are confused by many taxonomists and some considered that the morphometric changes of Tegillarca are only the habitual adaptation. But the collected samples from the same habitat from the southern part of India is clearly demarked the distinction between Anadara species and Tegillarca species. In this paper the differences between these two genera are illustrated with the help of specimens from the same habitat and with the help of taxonomic literature of these genera. Species level classification was done based on the morphometric characters like peculiarities of (i) periostracum, (ii) cardinal area, (iii) umbo, (iv) adductor muscle scar and (v) pallial line. The specimens were collected from Neendakara, Vizhinjam and Kovalam along with the south west coast and Thiruchendur in Tamil Nadu, south east coast of India.

Res. 12 (2): 1143-1154 (2013) Received July 27, 2012 Accepted October 9, 2012 Published April 10, 2013 DOI http://dx.doi.org/10.4238/2013.April.10.9 ABSTRACT. The blood cockle, Tegillarca granosa, is a widely consumed clam in the Indo-Pacific region. Glutamine synthetase (GS) is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine. We identified the GS ofT. granosa (Tg-GS) from hemocytes by 3'- and 5'-rapid amplification of cDNA ends (RACE)-PCR. The full- length cDNA consisted of 1762 bp, with a 1104-bp open reading frame encoding 367 amino acids. Sequence comparison showed that Tg-GS has homology to GS of other organisms, with 79.78% identity with GS from the Pacific oyster Crassostrea gigas, 71.98% identity with GS from the zebrafishDanio rerio, and 68.96% identity with human Homo sapiens GS. A C-beta-Grasp domain and an N-catalytic domain were identified in Tg-GS, indicating that Tg-GS should be classified as a new member of the GS family. A quantitative RT-PCR assay was used to detect mRNA expression of Tg-GS in fivedifferent tissues.

    Vol. 452: 119–130, 2012 MARINE ECOLOGY PROGRESS SERIES Published April 25 doi: 10.3354/meps09624 Mar Ecol Prog Ser Phylogeography of the bivalve Tegillarca granosa in coastal China: implications for management and conservation Gang Ni, Qi Li*, Lingfeng Kong, Xiaodong Zheng The Key Laboratory of Mariculture, Ministry of Education, Ocean University of China, Qingdao 266003, PR China ABSTRACT: Present genetic patterns of marine organisms not only result from historical and con- temporary ecological factors, but also from anthropogenic activities. Disentangling the relative effects of these factors can provide valuable insights into management and protection of exploitable species. The commercially important marine clam Tegillarca granosa is representative of species that are translocated within East Asia for coastal aquaculture purposes. We conducted a nucleotide sequence analysis of mitochondrial cytochrome c oxidase subunit I and nuclear inter- nal transcribed spacer 1 markers in T. granosa to investigate its genetic diversity and distribution in 2 marginal seas (the East and South China Seas) of the northwestern Pacific. Based on phyloge- netic inferences, we identified 2 evolutionarily significant units (ESUs) with high genetic distance between them for both markers. The high genetic distance may be associated with the historical isolation of the marginal seas during low sea level periods. One ESU was widely distributed in both seas, whereas the other was restricted to 2 disjunct localities in the South China Sea. Based on the isolation by distance analysis (p = 0.068) and comparison of patterns of co-occurring spe- cies, this pattern appears to be mostly attributable to the human-mediated translocations among coastal waters rather than natural range expansion.

  • Population Dynamics of the Comb Pen Shell Atrina Pectinata
    Philippine Journal of Science 150 (3): 1051-1060, June 2021 ISSN 0031 - 7683 Date Received: 21 Dec 2020 Population Dynamics of the Comb Pen Shell Atrina pectinata (Linnaeus, 1767) (Mollusca, Bivalvia: Pinnidae) Collected by Diving from Shallow Areas of the Southwest Visayan Sea, Northeastern Panay Island, Philippines Annabelle del Norte-Campos*, Switzel S. Lapara, and Kris Angeli S. Sanchez Marine Biology Lab, Division of Biological Sciences College of Arts and Sciences, University of Philippines Visayas Miagao, Iloilo, Philippines With the objective of determining the population dynamics of the comb pen shell (Atrina pectinata) (Mollusca, Bivalvia: Pinnidae) collected by divers in the southwest Visayan Sea, length-frequency data recorded between June 2018 and May 2019 were analyzed using the FiSAT software. von Bertalanffy growth parameters for the species were SL = 40.69 cm and K = 0.78 yr–1 the range of values for other fast-growing tropical bivalves. The estimated mean growth rate of 0.15 ± 0.05 cm d–1 likewise supports a fast growth rate and a short lifespan (< 1 yr) of the population. The recruitment pattern shows one major and minor pulse that coincides with the northeast monsoon and just prior to the southwest monsoon, respectively. Using ELEFAN II, total mortality (Z) of 2.79 yr–1 was estimated. From an averaged M/K value from the related bivalve literature (1.51) multiplied by the species’ own K, natural mortality (M) of 1.18 yr–1 was estimated, which when subtracted from the Z, gave fishing mortality (F) of 1.61 yr-1 and an exploitation rate E of 0.58, considered overexploited.

Blood cockles are among the most economically im- portant brackish water invertebrates found in Malaysia. However, our knowledge of blood cockle phylogeny and systematics is rudimentary, especially for the species Tegillarca granosa. It is unclear, for instance, whether the cockles occurring on the west coast of peninsular Malaysia constitute a single species, or multiple, phylogenetically distinct spe- cies. We performed the first DNA molecular phylogenetic analysis of T. granosa to distinguish it from other related species found in other parts of the world and to create a DNA database for the species. An approximately 585-nucleotide fragment of the mitochondrial DNA (cytochrome oxidase I, COI) was sequenced for 150 individual cock- les, representing 10 populations: three from the north, four from the central part and three from the southern part of peninsular Malaysia. Phylogenetic analyses of the resulting dataset yielded tree topologies that not only showed the relationship between T. granosa and its closest relatives but its position in the evolutionary tree. Three mitochondrial clades were evident, each containing an individual genus. Using the Genetics and Molecular Research 10 (2): 1237-1244 (2011) ©FUNPEC-RP www.funpecrp.com.br S.Y.

Ark clams and their relatives (Arcida) display two main ecologies represented by epifaunal and infaunal lifestyles. Their mantle margin includes features, such as photosensory and muscular organs, that may coincide with each habit, making these bivalves a suitable model to explore evolutionary convergence in the marine benthos. To test for the evolutionary association between lifestyles and morphology, we gathered data on the mantle margin for 64 species across all six extant arcidan families. A molecular phylogeny of Arcida was inferred based on four gene sequences from 54 species and used to study trait evolution. Our results support the hypothesis that photoreceptor organs had a single origin and that infaunal lineages lost these structures in independent events, suggesting a correlated pattern of evolution.

Kabat2 ABSTRACT Rudolph Amandus Philippi (known in Chile as Rodulfo Amando Philippi), was one of the longest-lived and most prolific malacologists of the 19th century, as his scientific work began in Germany in the 1830s and continued unabated until his death in Chile in 1904. Philippi contributed significantly to malacology: he described over 2,500 new taxa of Recent and fossil molluscs from around the world (2,528 species, 40 genera and three families), particularly from Italy and Chile, and discussed numerous taxa described by other authors. Philippi initially published primarily on Recent and fossil molluscs from Europe in the 1830s, then expanded to marine molluscs from around the world by the 1840s. In 1851, Philippi escaped the German Revolution by emigrating to Chile, where in 1853 he became the director of what is now the Museo Nacional de Historia Natural (Santiago) and a professor at the Universidad de Chile.

Robicheau2, Donald T. Stewart3, Eric Pante4,5 & Sophie Breton1,5* In animals, strictly maternal inheritance (SMI) of mitochondria is the rule, but one exception (doubly uniparental inheritance or DUI), marked by the transmission of sex-specifc mitogenomes, has been reported in bivalves. Associated with DUI is a frequent modifcation of the mitochondrial cox2 gene, as well as additional sex-specifc mitochondrial genes not involved in oxidative phosphorylation.
