Cosmopolitan heterotrophic microeukaryotes are active bacterial grazers in experimental oil-polluted systems
Dalby, A. P.; Kormas, K. A.; Christaki, U.; Karayanni, H. (2008)We investigated the population dynamics and prevailing 18S rDNA phylotypes of microeukaryotes (<= 10 mu m) in microcosms containing seawater from either an unpolluted oligotrophic site or a chronically oil-polluted mesotrophic ... -
Establishment and Succession of an Epibiotic Community on Chromated Copper Arsenate-Treated Wood in Mediterranean Waters
Karayanni, H.; Kormas, K. A.; Cragg, S.; Nicolaidou, A. (2010)Colonization and succession of an epibiotic animal community on chromated copper arsenate (CCA)-treated wood were studied for 18 months in the eastern Mediterranean (Saronikos Gulf, Aegean Sea). Pine wood panels, 200 x 100 ... -
Harmful and parasitic unicellular eukaryotes persist in a shallow lake under reconstruction (L. Karla, Greece)
Nikouli, E.; Kormas, K. A.; Berillis, P.; Karayanni, H.; Moustaka-Gouni, M. (2013)The reconstructed Lake Karla, Greece, has been undergoing its water-filling period since November 2009. In this paper, we aimed at investigating whether the unicellular eukaryotes, including the toxic/parasitic ones, that ... -
Heterotrophic nanoflagellate and ciliate bacterivorous activity and growth in the northeast Atlantic Ocean: A seasonal mesoscale study
Karayanni, H.; Christaki, U.; Van Wambeke, F.; Thyssen, M.; Denis, M. (2008)The grazing effect of heterotrophic nanoflagellates (HNF) and ciliates on bacterial production (BP), as well as their growth rates, was studied in winter, spring and autumn 2001 during the French research project Programme ... -
Inter-comparison of the potentially active prokaryotic communities in the halocline sediments of Mediterranean deep-sea hypersaline basins
Kormas, K. A.; Pachiadaki, M. G.; Karayanni, H.; Leadbetter, E. R.; Bernhard, J. M.; Edgcomb, V. P. (2015)The sediment microbiota of the Mediterranean deep-sea anoxic hypersaline basins (DHABs) are understudied relative to communities in the brines and halocline waters. In this study, the active fraction of the prokaryotic ... -
Microbial Food Web Structure and Its Impact on Primary Production in a Meso-Oligotrophic Coastal Area (Pagasitikos Gulf, Aegean Sea)
Kormas, K. A.; Karayanni, H.; Christaki, U.; Giannakourou, A.; Assimakopoulou, G.; Gotsis-Skretas, O. (2014)Seasonal structure and dynamics of the planktonic microbial food web (phytoplankton, bacteria, nanoflagellates and ciliates) were studied in the meso-oligotrophic Pagasitikos Gulf, NW Aegean Sea. Pagasitikos Gulf is exposed ... -
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 ... -
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 ...
