Han; K.W. Chung; G.H. Kim; Kang, Sung-Ho; T.A. Klochkova; S.J. Kim; Choi, Han-Gu Abstract: A field survey of algae and cyanobacteria from terrestrial and freshwater habitats in the vicinity of Ny-Alesund and on Blomstrandhalvoya Island (Svalbard) was performed in June 2009, and results were compared with data from our fieldwork in June 2006. In total, we identified 30 taxa belonging to 23 genera from the specimens collected near Ny-Alesund (26 taxa) and on Blomstrandhalvoya Island (24 taxa). Five species previously unrecorded from this locality are depicted, including astaxanthin-containing Haematococcus sp. collected from Blomstrandhalvoya Island. This is the first report on a Haematococcus species from the High Arctic.

In this study, we determined the complete mitochondrial DNA sequence of Homarus americanus, the first representative of the family to be fully caracterized.crayfishes, and their relatives) is very limited and represented by only on complete mitochondrial DNA sequence from the Australian freshwater crayfish species Cherax destructor.

For the conservation and restoration of this species, it is necessary to understand the current population structures of Korean C. similis using estimation of their genetic variation. In this study, eight microsatellite loci were developed and characterized from 49 individuals collected from four locations: one population from Mt. Bukhan (BH) and three populations from Mt. Gwanak (GA) in Seoul, Korea. As a result, the number of alleles per locus ranged from 2 to 12. The observed heterozygosities and expected heterozygosities ranged from 0.000 to 0.833 and from 0.125 to 0.943, respectively, and the former values were significantly lower than the latter ones expected under the Hardy- Weinberg equilibrium. No significant linkage disequilibrium was revealed between any of the locus pairs after Bonferroni correction. From the pairwise Fst results over all samples, higher differentiation between GA-BH population pairs (mean 0.1789) was bserved than between GA population pairs (mean 0.0454). This was also supported by Mantel's test showing that the genetic distances of these crayfish populations were significantly correlated with geographic distances.ssary to understand the current population structures of Korean C. similis using estimation of their genetic variation.

Analysis of the 16S rRNA gene sequence of the strain showed an affiliation with the genus Spongiibacter, sharing 93.9？% and 93.7？% sequence similarities with the type strains of Spongiibacter tropicus CL-CB221T and Spongiibacter marinus HAL40bT, respectively. Phylogenetic analyses revealed that strain CL-AS9T formed a separate branch that was distinct from a clade comprising Spongiibacter marinus HAL40bT, Spongiibacter tropicus CL-CB221T and Melitea salexigens 5IX/A01/131T. Cells of the strain grew optimally at 20？25 °C and pH 6.6？8.0 in the presence of 3？4？% (w/v) sea salts. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified aminophospholipid. The major quinone was ubiquinone 8. The major cellular fatty acids were C16？:？1ω7c and/or iso-C15？:？0 2-OH (23.1？%), C17？:？1ω8c (22.1？%) and C18？:？1ω 7c (15.6？%). The genomic DNA G+C content was 53.6 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data presented, we propose the name Spongiibacter borealis sp. nov. with the type strain CL-AS9T (？=？KCCM 90094T ？=？JCM 17304T) and the reclassification of Melitea salexigens as a later heterotypic synonym of S02;% and 93.7？% sequence similarities with the type strains of Spongiibacter tropicus CL-CB221T and Spongiibacter marinus HAL40bT, respectively.
