  • The Chloroplast Rpl23 Gene Cluster of Spirogyra Maxima (Charophyceae) Shares Many Similarities with the Angiosperm Rpl23 Operon
    Algae Volume 17(1): 59-68, 2002 The Chloroplast rpl23 Gene Cluster of Spirogyra maxima (Charophyceae) Shares Many Similarities with the Angiosperm rpl23 Operon Jungho Lee* and James R. Manhart Department of Biology, Texas A&M University, College Station, TX, 77843-3258, U.S.A. A phylogenetic affinity between charophytes and embryophytes (land plants) has been explained by a few chloro- plast genomic characters including gene and intron (Manhart and Palmer 1990; Baldauf et al. 1990; Lew and Manhart 1993). Here we show that a charophyte, Spirogyra maxima, has the largest operon of angiosperm chloroplast genomes, rpl23 operon (trnI-rpl23-rpl2-rps19-rpl22-rps3-rpl16-rpl14-rps8-infA-rpl36-rps11-rpoA) containing both embryophyte introns, rpl16.i and rpl2.i. The rpl23 gene cluster of Spirogyra contains a distinct eubacterial promoter sequence upstream of rpl23, which is the first gene of the green algal rpl23 gene cluster. This sequence is completely absent in angiosperms but is present in non-flowering plants. The results imply that, in the rpl23 gene cluster, early charophytes had at least two promoters, one upstream of trnI and another upstream of rpl23, which partially or completely lost its function in land plants. A comparison of gene clusters of prokaryotes, algal chloroplast DNAs and land plant cpDNAs indicated a loss of numerous genes in chlorophyll a+b eukaryotes. A phylogenetic analysis using presence/absence of genes and introns as characters produced trees with a strongly supported clade contain- ing chlorophyll a+b eukaryotes. Spirogyra and embryophytes formed a clade characterized by the loss of rpl5 and rps9 and the gain of trnI (CAU) and introns in rpl2 and rpl16.

Closing PCP nets (0.06-mm mesh) were also towed to evaluate vertical distrib ution patterns in September 1990, November 1991 and February 1997. P. minutus was present throughout the year. The population structure was characterized by nu merous early copepodite stages in February-April, largely copepodite V (CV) in May-November, and a rapid increase of adults in November to January. As the ex clusive component of the population, CVs were distributed below 300 m in Septem ber and November both day and night. These CVs were considered to be in dia pause. In February most of the Cl to CIV stages were concentrated in the top 100 m. All copepodite stages of P. newmani were collected for only 7 months of the year, disappearing from the water column in Toyama Bay from mid-June onward and their very small population recovered in November.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract The Japanese pond smelt (Hypomesus nipponensis) stock has been observed to fluctuate quite ri- gorously over the years with sustained periods of low catch in Lake Kasumigaura and Kitaura of the Ibaraki prefecture, Japan which would adversely affect the socioeconomic livelihood of the lo- cal fishermen and fisheries industry. This study was aimed at determining the factors affecting the stock fluctuation of the pond smelt through the different years in the two lakes. Through explora- tory analysis it was found that the pond smelt had significant relationship with total phosphorus (TP) level in both lakes. The global mean land and ocean temperature index (LOTI) was also found to be indirectly related to the pond smelt stock in lake Kasumigaura and Kitaura at the latitude band of 24˚N to 90˚N (l).

    Glossary of Fish Technology Terms A Selection of Terms Compiled by Kevin J. Whittle and Peter Howgate Prepared under contract to the Fisheries Industries Division of the Food and Agriculture Organization of the United Nations 6 December 2000 Last updated: February 2002 Kevin J. Whittle 1 GLOSSARY OF FISH TECHNOLOGY TERMS [Words highlighted in bold in the text of an entry refer to another entry. Words in parenthesis are alternatives.] Abnormalities Attributes of the fish that are not found in the great majority of that kind of fish. For example: atypical shapes; overall or patchy discolorations of skin or of fillet; diseased conditions; atypical odours or flavours. Generally, the term should be used for peculiarities present in the fish at the time of capture or harvesting, or developing very soon after; peculiarities arising during processing should be considered as defects. Acetic acid Formal chemical name, ethanoic acid. An organic acid of formula CH3.COOH. It is the main component, 3-6%, other than water, of vinegar. Used in fish technology in preparation of marinades. Acid curing See Marinating Actomyosin A combination of the two main proteins, actin and myosin, present in all muscle tissues. Additive A chemical added to a food to affect its properties. Objectives of including additives in a product include: increased stability during storage; inhibition of growth of microorganisms or production of microbial toxins; prevention or reduction of formation of off-flavours; improved sensory properties, particularly colours and appearance, affecting acceptability to the consumer; improved properties related to preparation and processing of food, for example, ability to create stable foams or emulsions, or to stabilise or thicken sauces.

  • Coexistence of Resident and Anadromous Pond Smelt, Hypomesus Nipponensis, in Lake Ogawara
    33 Coexistence of resident and anadromous pond smelt, Hypomesus nipponensis, in Lake Ogawara SATOSHIKATAYAMA Graduate School of Agricultural Science, Tohoku University, Sendai, 981-8555, Japan (katayama@bios. tohoku. ac.jp) SUMMARY. Pond smelt, Hypomesus nipponensis, inhabit fresh, brackish, and oceanic waters, and support substantial commercial fisheries in Japanese lakes. Pond smelt in Lake Ogawara, northern Japan, display a bimodal body length distribution during the spawning season, despite being 0+ fish. Analyses of otolith microstructure and microchemistry were utilized to discriminate anadromous from resident individuals, and revealed that individuals smaller than 60 mm SL were resident, those between 60-80 mm were mixed resident and anadromous, and those larger than 80 mm were anadromous. Intensive research on the reproductive ecology identified spawning localities in the lake and inflowing rivers. Although only anadromous fish spawned in inflowing rivers, spawners in the lake were a mixture of anadromous and resident individuals, suggesting that anadromous and resident spawning groups share a common spawning ground. These fish spawn during almost the same period from mid March to early May. Therefore, reproductive isolation does not appear to occur, and genetic differentiation has not been found through isozyme and mtDNA analyses. The anadromous and resident life history styles appear to be ecological variations within a single population. Lastly, qualitative and quantitative contributions of migratory and non-migratory pond smelts to the next generation were examined and heterogeneity in the life history of this population was discussed. KEYWORDS: residence, anadromy, pond smelt, alternative life history styles INTRODUCTION throughout the year and all over the take. 2,3) Anadromous migration has been studied mainly for salmonids.

  • Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
    Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton.

Mecklenburg & Peter Rask Møller & Dirk Steinke Received: 3 June 2010 /Revised: 23 September 2010 /Accepted: 1 November 2010 # Senckenberg, Gesellschaft für Naturforschung and Springer 2010 Abstract Taxonomic and distributional information on each Six families in Cottoidei with 72 species and five in fish species found in arctic marine waters is reviewed, and a Zoarcoidei with 55 species account for more than half list of families and species with commentary on distributional (52.5%) the species. This study produced CO1 sequences for records is presented. The list incorporates results from 106 of the 242 species. Sequence variability in the barcode examination of museum collections of arctic marine fishes region permits discrimination of all species. The average dating back to the 1830s. It also incorporates results from sequence variation within species was 0.3% (range 0–3.5%), DNA barcoding, used to complement morphological charac- while the average genetic distance between congeners was ters in evaluating problematic taxa and to assist in identifica- 4.7% (range 3.7–13.3%). The CO1 sequences support tion of specimens collected in recent expeditions. Barcoding taxonomic separation of some species, such as Osmerus results are depicted in a neighbor-joining tree of 880 CO1 dentex and O. mordax and Liparis bathyarcticus and L. (cytochrome c oxidase 1 gene) sequences distributed among gibbus; and synonymy of others, like Myoxocephalus 165 species from the arctic region and adjacent waters, and verrucosus in M. scorpius and Gymnelus knipowitschi in discussed in the family reviews.
