  • A Genetical and Ecological Diversity of Fresh Water Prawns Macrobrachium Canarae and Caridina Gracilirostris from Kanyakumari Dist., Tamil Nadu, India

ISSN 0974-3073 Volume 2, Number 1 (2011), pp. 23-32 © International Research Publication House http://www.irphouse.com A Genetical and Ecological Diversity of Fresh Water Prawns Macrobrachium Canarae and Caridina Gracilirostris from Kanyakumari Dist., Tamil Nadu, India Siva Ranjanee S.1 and Mariapan N.2 1Department of Biotechnology, Vels University, Pallavaram, Chennai, India 2Senior Medical Writer, SIRO Clinpharm Pvt. Ltd., Thane (W) 400 607. India E-mail: [email protected], [email protected] Abstract Fresh water prawns are cultured widely around the world but little is known about the levels and patterns of genetic diversity. This paper reports the RAPD analysis of two species of fresh water prawns of Atydiae and Palaemonidiae family and the genus Macrobrachium and Caridina collected from Kanyakumari district. Specimens are identified using species-specific morphological characteristics. Morphological characters have limitations of describing intra specific genetic diversity as they are polygenic and expressions can be modified by the environment. The advent of molecular technique made possible not only the genetic analysis and also the study of evolutionary relationship. Molecular analysis of the morphologically identified species are done by extracting the DNA from the animal and concentration of DNA is measured using Nanodrop spectrophotometer at a wavelength of 280nm. Further analysis was performed with RAPD (Rapid Amplified Polymorphic DNA) a PCR (Polymerase Chain Reaction) based technique. It consist of genomic DNA, amplified with randomly constructed oligonucleotides. Specific quantity of extracted DNA was then amplified by multiplex PCR using random primers and 16S rRNA gene products was then analyzed using a bioanalyzer.

  • The Species Flocks in the Ancient Lakes of Sulawesi, Indonesia
    12 Aquatic biodiversity hotspots in Wallacea: the species fl ocks in the ancient lakes of Sulawesi, Indonesia T h o m a s v o n R i n t e l e n , K r i s t i n a v o n R i n t e l e n , M a t t h i a s G l a u b r e c h t , C h r i s t o p h D . S c h u b a r t a n d F a b i a n H e r d e r 12.1 Introduction Some of the world’s most spectacular species radiations or species fl ocks are found in so-called ‘ancient lakes’. Th ese are long-lived lakes that have existed for 100 000 years (Gorthner et al. 1994 , but see also Albrecht and Wilke 2008 ) or more (e.g. Lake Tanganyika and Lake Baikal). Ancient lakes are justifi ably regarded as hotspots of diversifi cation (e.g. Martens 1997 , Rossiter and Kawanabe 2000 ), even if not all ancient lake species fl ocks match the diversity of the super-fl ock of East African cichlids (e.g. Kornfi eld and Smith 2000 , Kocher 2004 ). Studies on the evo- lution of ancient lake organisms have continuously resulted in important insights into general patterns of speciation and radiation (e.g. Streelman and Danley 2003 ) ever since the seminal review of Brooks ( 1950 ). During the last decade, smaller ancient lakes (c. <1 000 km 2 ), which are generally less well investigated, have attracted increasing attention.

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

  • Effect of Feed on the Growth and Survival of Long Eyed Swimming
    Soundarapandian et al., 2:3 http://dx.doi.org/10.4172/scientificreports681 Open Access Open Access Scientific Reports Scientific Reports Research Article OpenOpen Access Access Effect of Feed on the Growth and Survival of Long Eyed Swimming Crab Podophthalmus vigil Fabricius (Crustacea: Decapoda) Soundarapandian P1*, Ravichandran S2 and Varadharajan D1 1Faculty of Marine Sciences, Centre of Advanced Study in Marine Biology, Annamalai University, Tamil Nadu, India 2Department of Zoology, Government Arts College, Kumbakonam, Tamil Nadu, India Abstract Food is considered to be the most potent factor affecting growth. Attempts to develop diets for culture of crabs have resulted in a variety of feeds. The absence of suitable feed either pellet or live food which can promote growth and survival is considered to be the most important lacuna in cultivation of crabs. So searching of economically viable feed to optimize the growth and survival in crabs are very much essential. In the present study the weight gain was higher in the crabs offered with Acetes sp. (86 g) followed by clam meat fed animals (47 g). The crabs fed with minimum amount of Acetes sp. (152 g) and maximum of clam meat (182 g). The FCR value was better in Acetes sp. (1.8) fed animal rather than clam meat fed animals (3.8). The survival rate was higher in Acetes sp. fed animals (92%) and lowest survival (72%) was observed in animals fed with clam meat. The survival was reasonable for both the feeds. But higher survival rate was reported in the animals fed with Acetes sp. than that of clam meat.

  • Evolutionary Origin of Type IV Classical Cadherins in Arthropods Mizuki Sasaki1,4, Yasuko Akiyama-Oda1,2 and Hiroki Oda1,3*
    Sasaki et al. BMC Evolutionary Biology (2017) 17:142 DOI 10.1186/s12862-017-0991-2 RESEARCHARTICLE Open Access Evolutionary origin of type IV classical cadherins in arthropods Mizuki Sasaki1,4, Yasuko Akiyama-Oda1,2 and Hiroki Oda1,3* Abstract Background: Classical cadherins are a metazoan-specific family of homophilic cell-cell adhesion molecules that regulate morphogenesis. Type I and type IV cadherins in this family function at adherens junctions in the major epithelial tissues of vertebrates and insects, respectively, but they have distinct, relatively simple domain organizations that are thought to have evolved by independent reductive changes from an ancestral type III cadherin, which is larger than derived paralogs and has a complicated domain organization. Although both type III and type IV cadherins have been identified in hexapods and branchiopods, the process by which the type IV cadherin evolved is still largely unclear. Results: Through an analysis of arthropod genome sequences, we found that the only classical cadherin encoded in chelicerate genomes was the type III cadherin and that the two type III cadherin genes found in the spider Parasteatoda tepidariorum genome exhibited a complex yet ancestral exon-intron organization in arthropods. Genomic and transcriptomic data from branchiopod, copepod, isopod, amphipod, and decapod crustaceans led us to redefine the type IV cadherin category, which we separated into type IVa and type IVb, which displayed a similar domain organization, except type IVb cadherins have a larger number of extracellular cadherin (EC) domainsthandotypeIVacadherins (nine versus seven). We also showed that type IVa cadherin genes occurred in the hexapod, branchiopod, and copepod genomes whereas only type IVb cadherin genes were present in malacostracans.Furthermore,comparative characterization of the type IVb cadherins suggested that the presence of two extra EC domains in their N-terminal regions represented primitive characteristics.
