Bacteria are relevant members of planktonic food webs, both in terms of biomass and
production share. The assessment and comprehension of the factors that control bacterial …

We analyzed heterotrophic, pelagic bacterial production and specific growth rate data from
57 studies conducted in fresh, marine and estuarine/coastal waters. Strong positive …

There has been an explosion of research on marine microbial foodweb processes in the
past decade. Today it is widely accepted that about 50% of the primary production in marine …

Despite differences in the species compositions and absolute abundances of planktonic
microorganisms in fresh-and saltwater, there are broad similarities in microbial food webs …

The microbial loop, now widely accepted as an important component of aquatic food webs,
includes bacteria, cyanobacteria, and a variety of amoeboid, flagellated and ciliated protists …

Small unicellular algae in the size range of picoplankton (0.2-2.0/-Lm; Sieburth et al., 1978)
are ubiquitous components of pelagic ecosystems. They contribute substantially to both …

Field and laboratory experiments were conducted to compare the rates of ingestion of
planktonic protozoa for chroococcoid cyanobacteria and heterotrophic bacteria, and the fate …

Bacterial growth efficiency was examined in batch cultures and continuous flow cultures by
inoculating natural assemblages of pelagic bacteria from different localities into particle‐free …

A brief overview of the state-of-the-art of freshwater autotrophic picoplankton (APP) is given
as an introduction to this special issue of Internationale Revue der gesamten Hydrobiologie …

Primary producers must respond to the diel changes in light availability. Therefore, detection
of diel cycles in bacterial activity would imply tight coupling between the production of …
