We explored the seasonal and vertical patterns of cell numbers, biomass, and amino acid incorporation of three major phylogenetic groups of the bacterioplankton in an oligomesotrophic alpine lake. Throughout the year the numerically dominant bacteria in the oxygenated epilimnion were small Actinobacteria. The timing and vertical location of their spring peak coincided with that of the heterotrophic flagellates (HNF). A second maximum of the relative proportions of Actinobacteria occurred during… 

Quantitative dominance of seasonally persistent filamentous cyanobacteria (Planktothrix rubescens) in the microbial assemblages of a temperate lake

It is concluded that P. rubescens represents a powerful competitor of autotrophic and heterotrophic prokaryotes, likely due to both its specific physiological properties and its protection against zooplankton grazing, which might be regarded as another reason for its mass occurrence in numerous lakes of the Northern hemisphere.

Seasonal bloom dynamics and ecophysiology of the freshwater sister clade of SAR11 bacteria ‘that rule the waves’ (LD12)

LD12 bacteria do not only share phenotypic and metabolic traits with Pelagibacter, but also seem to thrive in the analogous spatiotemporal niche in freshwaters.

Temporal changes in the dominance of major planktonic bacterial groups in an alpine lake: discrepancy with their contribution to bacterial production

The results show that bacterial abundance and production are not necessarily dominated by the same phylogenetic groups.

Vertical and longitudinal distribution patterns of different bacterioplankton populations in a canyon‐shaped, deep prealpine lake

This work studied the spatial distribution patterns of different heterotrophic bacteria, picocyanobacteria, and the dominant primary producer, the filamentous cyanobacterium Planktothrix rubescens, in a large, canyon-shaped, prealpine lake in six vertical profiles along a 21-km longitudinal transect to stress the potential importance of spatial niche differentiation in freshwater bacterioplankton.

In situ substrate preferences of abundant bacterioplankton populations in a prealpine freshwater lake

The substrate partitioning of sympatric populations of freshwater bacterioplankton was studied via microautoradiography and fluorescence in situ hybridization and the variable extent of specialization by the studied bacterial taxa on subsets of LMW compounds contrasts theoretical considerations about non-selective microbial substrate assimilation at oligotrophic conditions.

Contrasting trends in distribution of four major planktonic betaproteobacterial groups along a pH gradient of epilimnia of 72 freshwater habitats.

It is emphasized that at least two taxa of freshwater Betaproteobacteria represent ecologically diversified groups and substrate utilization patterns observed in laboratory experiments indicate no coherent group-specific differences in substrate preferences.

Seasonal dynamics and activity of typical freshwater bacteria in brackish waters of the Gulf of Gdańsk

All studied freshwater lineages were active members of the brackish water communities at specific environmental conditions, including LD12 Alphaproteobacteria, which have so far been considered to thrive exclusively in freshwater habitats.

Resilience of planktonic bacterial community structure in response to short-term weather deterioration during the growing season in an alpine lake

The disturbing effect of a short-term cooling period during summer on planktonic bacterial community structure of an alpine lake was investigated using 16S rDNA pyrosequencing. Proteobacteria,

Seasonal growth potential of rare lake water bacteria suggest their disproportional contribution to carbon fluxes.

The seasonal growth potential of opportunistic bacterial populations in Lake Zurich is studied by a series of grazer-free dilution culture assays to hint at a tight control by bacterivorous grazers and at a consequently accelerated carbon flux to higher trophic levels.

Coherent dynamics and association networks among lake bacterioplankton taxa

Bacteria have important roles in freshwater food webs and in the cycling of elements in the ecosystem. Yet specific ecological features of individual phylogenetic groups and interactions among these



Spatio-temporal niche separation of planktonic Betaproteobacteria in an oligo-mesotrophic lake.

In general, only moderate seasonal changes in abundance were observed in the upper water layers, whereas there was a clear relationship between decreasing oxygen levels and the rise of bacteria from the PnecC and beta IV clades in deeper strata.

Differences in structure and dynamics of Polynucleobacter communities in a temperate and a subtropical lake, revealed at three phylogenetic levels.

Interhabitat comparisons of the Polynucleobacter community structure in the two lakes in the study, and a previously investigated acidic pond indicated ecological diversification within the phylogenetically narrow Polyn nucleobacter cluster.

Dynamics of Bacterial Community Composition and Activity during a Mesocosm Diatom Bloom

Rate measurements as well as bacterial population dynamics were almost identical among the mesocosms indicating that the observed bacterial community dynamics were systematic and repeatable responses to the manipulated conditions.

Modulation of microbial predator-prey dynamics by phosphorus availability: growth patterns and survival strategies of bacterial phylogenetic clades.

By combining several single-cell methods, new insight is gained into the competitive abilities of freshwater bacteria from a variety of phylogenetic lineages under contrasting sets of bottom-up and top-down constraints.

Bloom of Filamentous Bacteria in a Mesotrophic Lake: Identity and Potential Controlling Mechanism

The identification of dominant members of a filamentous bacterial assemblage during a bloom of such morphotypes in a mesotrophic lake and the most pronounced case of dominance by a single bacterioplankton species ever observed in natural freshwaters points at the potential importance of filter-feeding zooplankon in controlling the occurrence and species composition of filamentousacterial morphotype in freshwater plankton.

Recurrent Seasonal Variations in Abundance and Composition of Filamentous SOL Cluster Bacteria (Saprospiraceae, Bacteroidetes) in Oligomesotrophic Lake Mondsee (Austria)

The overall composition of SOL communities was controlled by abiotic factors (water chemistry), while their dynamics seemed to be controlled byAbiotic and biotic interactions.

Diversity and Seasonal Dynamics of Actinobacteria Populations in Four Lakes in Northeastern Germany

Total Actinobacteria and members of the clusters acI and acI-B showed distinct seasonal changes in their absolute abundances, with maxima in late spring and fall/winter.

Comparative 16S rRNA Analysis of Lake Bacterioplankton Reveals Globally Distributed Phylogenetic Clusters Including an Abundant Group of Actinobacteria

A combination of phylogenetic analysis and FISH was used to reveal 16 globally distributed sequence clusters and to confirm the broad distribution, abundance, and high biomass of members of the class Actinobacteria in freshwater ecosystems.

Archaeal dominance in the mesopelagic zone of the Pacific Ocean

A year-long study of the abundance of two specific archaeal groups (pelagic euryarchaeota and pelagic crenarchAEota) in one of the ocean's largest habitats suggests that most pelagic deep-sea microorganisms are metabolically active and the results suggest that the global oceans harbour approximately 1.3 × 1028Archaeal cells, and 3.1‬×‬10 28 bacterial cells.

The community structure of pelagic microbial assemblages can be influenced by the taxonomic composition of the predator community, albeit to different extents.
