We investigated bacterial responses to variations in dissolved organic carbon (DOC) and
nutrient availability by a comparative analysis of bacterial metabolism in lakes ranging from …

The balance of production in any ecosystem is dependent on the flow of limiting nutrients
into either the autotrophic or heterotrophic components of the food web. To understand one …

A series of bioassay experiments were performed from spring to autumn in a small dimictic
lake (Deep Pond, Massachusetts) to examine the potential for bacterial growth limitation by …

A bstract In natural bacterioplankton assemblages, only a fraction of the total cell count is
active, and, therefore, rates of bacterial production should be more strongly correlated to the …

Heterotrophic bacteria are a key component driving biogeochemical processes in aquatic
ecosystems. In 1998, we examined the role of heterotrophic bacteria by quantifying plankton …

The seasonal variation in the carbon growth yield of pelagic bacteria in the eutrophic lake
Frederiksborg Slotssø was studied. The growth yield was determined in dilution culture …

We carried out enclosure experiments in an unproductive lake in northern Sweden and
studied the effects of enrichment with different dissolved organic carbon (glucose)/inorganic …

We measured bacterial abundance, cell size distribution, and related microbiological and
geochemical parameters in 20 stratified lakes from three regions in the US Both largest cell …

We examined the potential limitation of bacterial growth by temperature and nutrients in a
eutrophic lake. Dilution cultures from winter and summer were incubated at both high (> 20° …

It has been suggested that autochthonous (internally produced) organic carbon and
allochthonous (externally produced) organic carbon are utilized by phylogenetically different …
