    Field survey of Brassica oleracea growing in the wild in northwestern French coastal areas and AFLP analysis of their genetic diversity and population structure. This study offered the highest level of detail ever presented about the distribution of wild B. oleracea populations along the French Atlantic coast. Populations analysed showed a low level of genetic differentiation. Traditional varieties commonly grown in the same area were not fully distinguishable from the wild populations on a molecular level. The level of genetic diversity of the wild populations was similar to, or lower than that of the cultivated crops

    224-234Several environmental variables were monitored and water samples were examined from over a period of 17 days in December 2005 and January 2006 to understand the taxonomic structure of coastal phytoplankton communities at a coastal site near Mangalore. The phytoplankton community was characterized by identifying and quantifying microalgal taxa; in conjunction, also determined Chl a, inorganic nutrients, oxygen, salinity, temperature, total bacteria, and tidal range. Canonical correspondence analysis (CCA) was used to trace temporal phytoplankton community changes, and to examine the relationships between species composition and environmental factors. These variables were subjected to analysis, pair-wise, to identify correlations. The species diversity of the phytoplankton community changed rapidly, and high species diversity coincided with significantly higher relative diatom abundance, and lower species diversity coincided with significantly higher proportions of phytoplankton taxa other than diatoms and dinoflagellates. In addition, the Chl a concentration was positively correlated to the relative proportion of dinoflagellates. The relative abundance of some species was dependent on specific environmental variables, such as Chaetoceros tenuissimus that was found inversely correlated to salinity. We also found that the stage of the tides may have implication on the sampling, because it has an influence on species diversity and the proportion of specific microalgal groups. At declined water level, the relative proportion of diatoms and dinoflagellates was low, and generally the Chl a concentrations were also lower during low tide

    This article documents the addition of 512 microsatellite marker loci and nine pairs of Single Nucleotide Polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Alcippe morrisonia morrisonia, Bashania fangiana, Bashania fargesii, Chaetodon vagabundus, Colletes floralis, Coluber constrictor flaviventris, Coptotermes gestroi, Crotophaga major, Cyprinella lutrensis, Danaus plexippus, Fagus grandifolia, Falco tinnunculus, Fletcherimyia fletcheri, Hydrilla verticillata, Laterallus jamaicensis coturniculus, Leavenworthia alabamica, Marmosops incanus, Miichthys miiuy, Nasua nasua, Noturus exilis, Odontesthes bonariensis, Quadrula fragosa, Pinctada maxima, Pseudaletia separata, Pseudoperonospora cubensis, Podocarpus elatus, Portunus trituberculatus, Rhagoletis cerasi, Rhinella schneideri, Sarracenia alata, Skeletonema marinoi, Sminthurus viridis, Syngnathus abaster, Uroteuthis (Photololigo) chinensis, Verticillium dahliae, Wasmannia auropunctata, and Zygochlamys patagonica. These loci were cross-tested on the following species: Chaetodon baronessa, Falco columbarius, Falco eleonorae, Falco naumanni, Falco peregrinus, Falco subbuteo, Didelphis aurita, Gracilinanus microtarsus, Marmosops paulensis, Monodelphis Americana, Odontesthes hatcheri, Podocarpus grayi, Podocarpus lawrencei, Podocarpus smithii, Portunus pelagicus, Syngnathus acus, Syngnathus typhle,Uroteuthis (Photololigo) edulis, Uroteuthis (Photololigo) duvauceli and Verticillium albo-atrum. This article also documents the addition of nine sequencing primer pairs and sixteen allele specific primers or probes for Oncorhynchus mykiss and Oncorhynchus tshawytscha; these primers and assays were cross-tested in both species.This article is from Molecular Ecology Resources 9 (2009): 1460, doi:10.1111/j.1755-0998.2009.02759.x.</p
