A Guide to the Natural History of Freshwater Lake Bacteria
SUMMARY Freshwater bacteria are at the hub of biogeochemical cycles and control water quality in lakes. Despite this, little is known about the identity and ecology of functionally significant lakeExpand

Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), andExpand

Transitions in bacterial communities along the 2000 km salinity gradient of the Baltic Sea
Salinity is a major factor controlling the distribution of biota in aquatic systems, and most aquatic multicellular organisms are either adapted to life in saltwater or freshwater conditions.Expand

Composition of freshwater bacterial communities associated with cyanobacterial blooms in four Swedish lakes.
The diversity of freshwater bacterioplankton communities has not been extensively studied despite their key role in foodwebs and the cycling of carbon and associated major elements. In order toExpand

Photochemical transformation of dissolved organic matter in lakes
In a survey of photochemical transformation of dissolved organic matter (DOM) in lake water, we found photochemical production of dissolved inorganic carbon (DIC) and low molecular weight carboxyliExpand

Heterotrophic Bacterial Growth Efficiency and Community Structure at Different Natural Organic Carbon Concentrations
ABSTRACT Batch cultures of aquatic bacteria and dissolved organic matter were used to examine the impact of carbon source concentration on bacterial growth, biomass, growth efficiency, and communityExpand

Pyrosequencing reveals contrasting seasonal dynamics of taxa within Baltic Sea bacterioplankton communities
Variation in traits causes bacterial populations to respond in contrasting ways to environmental drivers. Learning about this will help us understand the ecology of individual populations in complexExpand

Infrequent marine-freshwater transitions in the microbial world.
Until recently, the evolutionary relationships between marine and freshwater microbes were unclear, but the use of molecular phylogenies is beginning to shed light on this subject. An increasingExpand

Photochemically produced carboxylic acids as substrates for freshwater bacterioplankton
. High-molecular-weight dissolved organic matter is abundant in humic lakes and is a large potential source of energy for heterotrophic organisms. These substances are hard to degrade enzymaticallyExpand

Reactions of hydroxyl radical with humic substances: bleaching, mineralization, and production of bioavailable carbon substrates.
In this study, we examine the role of the hydroxyl (OH*) radical as a mechanism for the photodecomposition of chromophoric dissolved organic matter (CDOM) in sunlit surface waters. UsingExpand
