For lake microbes, water column mixing acts as a disturbance because it homogenizes
thermal and chemical gradients known to define the distributions of microbial taxa. Our first …

We have investigated the ecology of viruses in Lake Bourget (France) from January to
August 2008. Data were analysed for viral and bacterial abundance and production, viral …

We examined the role of heterotrophic bacterioplankton in structuring diel patterns in
community respiration (CR) in an oligotrophic alpine lake. We used continuous …

We used phospholipid fatty acids (PLFA) to determine microbial biomass and community
structure in the sediments of eight boreal lakes with different loadings of allochthonous …

Allochthonous and autochthonous organic matter deposited in benthic sediments are
mineralized by microbial communities, resulting in release of nutrients to the water column …

Human impacts such as eutrophication, overexploitation and climate change currently
threaten future global food and drinking water supplies. Consequently, it is important that we …

Bacterial carbon demand, an important component of ecosystem dynamics in polar waters
and sea ice, is a function of both bacterial production (BP) and respiration (BR). BP has …

This study focused on how phosphorus and carbon control pelagic bacteria in lakes over a
gradient of dissolved organic carbon (DOC from 6.7 to 29.5 mg CL− 1) and phosphorus (P …

Nutrient enrichment of high-elevation freshwater ecosystems by atmospheric deposition is
increasing worldwide, and bacteria are a key conduit for the metabolism of organic matter in …

Abstract Seven cruises during June 2005–November 2006 were conducted to study the
variations in apparent oxygen utilization in Hong Kong coastal waters, and PO 4 addition …
