A Genetical and Ecological Diversity of Fresh Water Prawns Macrobrachium Canarae and Caridina Gracilirostris from Kanyakumari Dist., Tamil Nadu, India
International Journal of Genetic Engineering and Biotechnology. 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. -
A Dangling Slab, Amplified Arc Volcanism, Mantle Flow and Seismic Anisotropy in the Kamchatka Plate Corner
AGU Geodynamics Series Volume 30, PLATE BOUNDARY ZONES Edited by Seth Stein and Jeffrey T. Freymueller, p. 295-324 1 A Dangling Slab, Amplified Arc Volcanism, Mantle Flow and Seismic Anisotropy in the Kamchatka Plate Corner Jeffrey Park,1 Yadim Levin,1 Mark Brandon,1 Jonathan Lees,2 Valerie Peyton,3 Evgenii Gordeev ) 4 Alexei Ozerov ,4 Book chapter in press with "Plate Boundary Zones," edited by Seth Stein and Jeffrey Freymuller Abstract The Kamchatka peninsula in Russian East Asia lies at the junction of a transcurrent plate boundary, aligned with the western Aleutian Islands, and a steeply-dipping subduction zone with near-normal convergence. Seismicity patterns and P-wave tomography argue that subducting Pacific lithosphere terminates at the Aleutian junction, and that the downdip extension (>150km depth) of the slab edge is missing. Seismic observables of elastic anisotropy (SKS splitting and Love-Rayleigh scattering) are consistent \Vith asthenospheric strain that rotates from trench-parallel beneath the descending slab to trench-normal beyond its edge. Present-day arc volcanism is concentrated near the slab edge, in the Klyuchevskoy and Sheveluch eruptive centers. Loss of the downdip slab edge, whether from thermo-convective or ductile instability, and subsequent "slab-window" mantle return flow is indicated by widespread Quaternary volcanism in the Sredinny Range inland of Klyuchevskoy and Sheveluch, as well as the inferred Quaternary uplift of the central Kamchatka depression. The slab beneath Klyuchevskoy has shallower dip (35°) than the subduction zone farther south (55°) suggesting a transient lofting of the slab edge, either from asthenospheric flow or the loss of downdip load. -

COMMISSIONED REPORT Summary Seagrass (Zostera) beds in Orkney Commissioned Report No. 765 Project No: 848 Contractors: Emma Jackson (The Marine Biological Association of the United Kingdom) and Malcolm Thomson (Sula Diving) Year of publication: 2014 Keywords Seagrass; Zostera marina; Orkney; predictive model; survey. Background Seagrasses (Zostera spp) are marine flowering plants that develop on sands and muds in sheltered intertidal and shallow subtidal areas. Seagrass beds are important marine habitats but are vulnerable to a range of human induced pressures. Their vulnerability and importance to habitat creation and ecological functioning is recognised in their inclusion on the recommended Priority Marine Features list for Scotland’s seas. Prior to this study, there were few confirmed records of Zostera in Orkney waters. This study combined a predictive modelling approach with boat-based surveys to enhance under- standing of seagrass distribution in Orkney and inform conservation management. -
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. -

Hong Kong's Bad Biodiversity
JULY 2001 NUMBER 23 Porcupine! Newsletter of the Department of Ecology & Biodiversity, The University of Hong Kong Hong Kong's Bad Biodiversity Aliens - also known as exotics or introduced species - are species which did not occur here naturally but have been brought to Hong Kong by humans, either deliberately, as crops, ornamentals, domestic animals or pets, or accidentally, as stowaways in ships and cargo planes, as seeds or eggs in soil, or attached to shoes or clothing. Most species which arrive in this way do not "escape" to form wild populations, and most of the species which have escaped are confined to places that are continually disturbed by humans. The weeds of cultivated areas, roadsides and urban wasteland are mostly exotics, as are the fish in concrete channels, and such conspicuous urban invertebrates as the "American" Cockroach and the Giant African Snail. Most of these urban exotics are doing no obvious harm and some contribute positively to the quality of city life. However, they also form the pool of species from which are drawn the small number of ecologically-damaging ones: the invasive species. Invasive species are aliens that invade natural or semi-natural communities. Out of the 150 or so well-established alien plant species in Hong Kong, less than a dozen have become invasive. The climbing American composite Mikania micrantha – Mile-a-Minute – is the most obvious example, but even this is confined to relatively disturbed sites. The "success" rate seems to be higher among birds and mammals, but the species which have done well in natural habitats are all from tropical East Asia and are apparently occupying niches vacated by the loss of the same or closely-related species when Hong Kong was deforested centuries ago. -
Volume 19 Winter 2002 the Coral Hind, Lapu Lapu, Or Miniata
FREE ISSN 1045-3520 Volume 19 Winter 2002 Introducing a Zonal Based Natural Photo by Robert Fenner Filtration System for Reef Aquariums by Steve Tyree Quite a few natural based filtration systems have been devised by reef aquarists and scientists in the past twenty years. Some systems utilized algae to remove organic and inorganic pollutants from the reef aquarium; others utilized sediment beds. The natural filtration system that I have been researching and designing is drastically different from both of these types. No external algae are used. I believe that all the algae a functional reef requires are already growing in the reef, even if they are not apparent. They include micro-algae, turf algae, coralline algae, single-cell algae within photosynthetic corals, and cyanobacteria with photosynthetic capabilities. Most of the systems that I have set up to research this concept have not included sediment beds. All organic matter and pollutants are recycled and processed within the system by macro-organisms. Sediment beds have not been utilized to process excess Miniata Grouper, Cephalopholis miniata organic debris, but that does not prevent other aquarists from adding them. The main concept behind my system is the use of living sponges, sea squirts, and filter feeders for filtration. Sponges consume bacteria, can reach about twenty inches in length in the wild, and dissolved and colloidal organic material, micro-plankton, The Coral Hind, Lapu about half that in captivity. It is undoubtedly the most and fine particulate matter. Sea squirts consume large Lapu, or Miniata prized member of the genus for the aquarium trade. -

Of them, the bathypelagic P. exilimanus is new to the Japanese fauna. The other three species are abyssobenthic, extending to depths greater than 3000 m, and thus have been rarely collected. The newly collected samples of H. gracialis enable us to reassess diagnostic characters of the species. Nematocarcinus longirostris is rediscovered since the original description, and the taxonomy of the species is reviewed. Glyphocrangon caecescens is the sole representative of the family extending to off northern Japan.

Copy Number Variation and Expression Analysis Reveals a Nonorthologous Pinta Gene Family Member Involved in Butterfly Vision
GBE Copy Number Variation and Expression Analysis Reveals a Nonorthologous Pinta Gene Family Member Involved in Butterfly Vision Aide Macias-Munoz~ 1,*, Kyle J. McCulloch1,2,andAdrianaD.Briscoe1,* 1Department of Ecology and Evolutionary Biology, University of California, Irvine 2FAS Center for Systems Biology, Harvard University *Corresponding authors: E-mails: [email protected];[email protected]. Accepted: November 8, 2017 Abstract Vertebrate (cellular retinaldehyde-binding protein) and Drosophila (prolonged depolarization afterpotential is not apparent [PINTA]) proteins with a CRAL-TRIO domain transport retinal-based chromophores that bind to opsin proteins and are neces- sary for phototransduction. The CRAL-TRIO domain gene family is composed of genes that encode proteins with a common N- terminal structural domain. Although there is an expansion of this gene family in Lepidoptera, there is no lepidopteran ortholog of pinta. Further, the function of these genes in lepidopterans has not yet been established. Here, we explored the molecular evolution and expression of CRAL-TRIO domain genes in the butterfly Heliconius melpomene in order to identify a member of this gene family as a candidate chromophore transporter. We generated and searched a four tissue transcriptome and searched a reference genome for CRAL-TRIO domain genes. We expanded an insect CRAL-TRIO domain gene phylogeny to include H. melpomene and used 18 genomes from 4 subspecies to assess copy number variation. A transcriptome-wide differential expression analysis comparing four tissue types identified a CRAL-TRIO domain gene, Hme CTD31, upregulated in heads suggesting a potential role in vision for this CRAL-TRIO domain gene. RT-PCR and immunohistochemistry confirmed that Hme CTD31 and its protein product are expressed in the retina, specifically in primary and secondary pigment cells and in tracheal cells.
