While typical freshwater and marine bacteria have been found to co‐occur in brackish habitats, it is unknown if they are active members of the local bacterial assemblages or their presence result passive transport only. We followed seasonal dynamics (R‐BT lineage Betaproteobacteria ; Ac1 Actinobacteria LD12 Alphaproteobacteria ) SAR11 water Gulf Gdańsk (southern Baltic Sea), we assessed incorporation thymidine leucine at three distinct environmental conditions. The temporal development was...
The biomass, production, composition of autotrophic phytoplankton and heterotrophic bacteria were studied along with environmental biological parameters. Samples taken from Vistula river water (at Kiezmark) the plume to outer stations in Gulf Gdańsk (Baltic Sea) June 2005. biomass gradient appeared be simply result dilution sea water, whereas bacterial abundance dropped between station first stations, a decrease that cannot explained by effect. stimulated production mainly bacterioplankton...
Cryptomonadales have acquired their plastids by secondary endosymbiosis. A novel clade— CRY 1—has been discovered at the base of tree, but it remains unknown whether contains plastids. are also an important component phytoplankton assemblages. However, they cannot be readily identified in fixed samples, and knowledge on dynamics distribution specific taxa is scarce. We investigated phenology 1 lineage, three cryptomonadales clades a species Proteomonas sulcata brackish lagoon Baltic Sea...
Abstract Although detritivorous Tubificinae and chironomid larvae are important groups in functioning of both, fresh brackish water ecosystem, their co-occurrence patterns sediment is weakly known. We carried out two-year-long research the Vistula Lagoon (southern Baltic Sea), where both ( Limnodrilus hoffmeisteri Potamothrix hammoniensis ) Chironomus balatonicus occur high densities. Because different source food, we hypothesized that ecological interactions between those two detritivores...
Bacterial production and the accompanying environmental factors were measured in water columns of two Arctic fjords during cruise July August 2013. Water samples collected at six stations located central part Hornsund Kongsfjorden. In Hornsund, where average temperatures 1.25-fold lower than Kongsfjorden, bacterial was twice as high (0.116 ± 0.102 vs 0.05 0.03 mg C m−3 h−1). Statistical analysis indicated that chlorophyll a concentration itself not significant factor affected production,...
The Gulf of Gdańsk is influenced by freshwater inflow from the River Vistula and a wind-driven current along coast. Bacterial communities five stations salinity gradient were sampled during one day analysed terminal restriction fragment length polymorphism (T-RFLP), catalysed reporter deposition-fluorescence in situ hybridisation (CARD-FISH) 16S rRNA gene libraries. On sampling, we observed probable current-driven seawater influx into inner part gulf that separated distinct water bodies....
