New findings on the true-branched monotypic genus Iphinoe (Cyanobacteria) from geographically isolated caves (Greece)
Lamprinou, V.; Hernandez-Marine, M.; Pachiadaki, M. G.; Kormas, K. A.; Economou-Amilli, A.; Pantazidou, A. (2013)The type of branching is a morphological character of great significance; separating taxa within the true-branched cyanobacteria. In this paper, true-branched morphospecies of cyanobacteria belonging to genus Iphinoe ... -
A non-phylogenetic alpha diversity approach on prokaryotic community structure in aquatic systems
Smeti, E.; Kormas, K. A.; Spatharis, S. (2013)Comparative analyses of accumulating phylotype-abundance data of prokaryotic communities are relatively scarce and mainly approached with phylogenetic methodologies. However, when a great fraction of phylotypes is captured ... -
Phytoplankton and water quality in a Mediterranean drinking-water reservoir (Marathonas Reservoir, Greece)
Katsiapi, M.; Moustaka-Gouni, M.; Michaloudi, E.; Kormas, K. A. (2011)Phytoplankton and water quality of Marathonas drinking-water Reservoir were examined for the first time. During the study period (July-September 2007), phytoplankton composition was indicative of eutrophic conditions ... -
Plankton Microorganisms Coinciding with Two Consecutive Mass Fish Kills in a Newly Reconstructed Lake
Oikonomou, A.; Katsiapi, M.; Karayanni, H.; Moustaka-Gouni, M.; Kormas, K. A. (2012)Lake Karla, Greece, was dried up in 1962 and its refilling started in 2009. We examined the Cyanobacteria and unicellular eukaryotes found during two fish kill incidents, in March and April 2010, in order to detect possible ... -
Polyphasic evaluation of Aphanizomenon issatschenkoi and Raphidiopsis mediterranea in a Mediterranean lake
Moustaka-Gouni, M.; Kormas, K. A.; Polykarpou, P.; Gkelis, S.; Bobori, D. C.; Vardaka, E. (2010)Aphanizomenon issatschenkoi and Raphidiopsis mediterranea were studied in the Mediterranean Lake Doirani during a cyanobacterial bloom (August-October 2004). Aphanizomenon issatschenkoi was clearly morphologically distinct ... -
Prokaryotic community structure and diversity in the sediments of an active submarine mud volcano (Kazan mud volcano, East Mediterranean Sea)
Pachiadaki, M. G.; Lykousis, V.; Stefanou, E. G.; Kormas, K. A. (2010)We investigated 16S rRNA gene diversity at a high sediment depth resolution (every 5 cm, top 30 cm) in an active site of the Kazan mud volcano, East Mediterranean Sea. A total of 242 archaeal and 374 bacterial clones were ... -
Raphidiopsis mediterranea Skuja represents non-heterocytous life-cycle stages of Cylindrospermopsis raciborskii (Woloszynska) Seenayya et Subba Raju in Lake Kastoria (Greece), its type locality: Evidence by morphological and phylogenetic analysis
Moustaka-Gouni, M.; Kormas, K. A.; Vardaka, E.; Katsiapi, M.; Gkelis, S. (2009)The taxonomical relationship of Cylindrospermopsis raciborskii and Raphidiopsis mediterranea was studied by morphological and 16S rRNA gene diversity analyses of natural populations from Lake Kastoria, Greece. Samples were ... -
Spatially uniform but temporally variable bacterioplankton in a semi-enclosed coastal area
Meziti, A.; Kormas, K. A.; Moustaka-Gouni, M.; Karayanni, H. (2015)Studies focusing on the temporal and spatial dynamics of bacterioplankton communities within littoral areas undergoing direct influences from the coast are quite limited. In addition, they are more complicated to resolve ... -
Temporal shifts of the Norway lobster (Nephrops norvegicus) gut bacterial communities
Meziti, A.; Ramette, A.; Mente, E.; Kormas, K. A. (2010)The aim of this study was to investigate the gut bacterial communities of Nephrops norvegicus individuals, using a suite of molecular tools consisting of automated ribosomal intergenic spacer analysis, 16S rRNA gene-internal ... -
Variability of Prokaryotic Community Structure in a Drinking Water Reservoir (Marathonas, Greece)
Lymperopoulou, D. S.; Kormas, K. A.; Karagouni, A. D. (2012)The structure of the Bacteria and Archaea community in a large drinking water reservoir (Marathonas, Greece; MR) was investigated in October 2007 and September 2008, using 16S rRNA gene clone libraries. The bacterial ... -
Winter-Summer Succession of Unicellular Eukaryotes in a Meso-eutrophic Coastal System
Christaki, U.; Kormas, K. A.; Genitsaris, S.; Georges, C.; Sime-Ngando, T.; Viscogliosi, E.; Monchy, S. (2014)The objective of this study was to explore the succession of planktonic unicellular eukaryotes by means of 18S rRNA gene tag pyrosequencing in the eastern English Channel (EEC) during the winter to summer transition. The ...
