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 …

The small average cell size of in situ bacterioplankton, relative to cultured cells, has been
suggested to be at least partly a result of selection of larger-sized cells by bacterivorous …

Rates of grazing on bacteria or phytoplankton by protists in natural waters may be estimated
by evaluating the average rate of particle ingestion by specific components of the protistan …

The paradigm of the'microbial loop'has became increasingly important for understanding the
structure and function of aquatic ecosystems. Most of the microbial loop studies have …

Simultaneous measurements were made of bacterioplankton productivity ([³H] thymidine
assay) and of bacterial mortality due to protozoan grazing (measured via uptake of …

We investigated feeding of natural populations of red-tide algae, heterotrophic
nanoflagellates (HNFs), and ciliates (< 30 µm in cell length) on natural populations of marine …

Current conventional wisdom argues that human-induced excesses in nutrient loadings to
estuaries often stimulate 'excess' algal production leading to hypoxia, via bacterial …

Protists and viruses are recognized as the main predators on bacteria in a variety of
environments. Several factors may potentially influence the grazing rates of protists on …

Nanoplankton and picoplankton abundance and community grazing on picoplankton were
determined in summer and autumn at several stations in a productive coastal environment …

Bacterial mortality has been investigated in freshwater (River Seine) and in marine (North
Sea) systems using a method based on following the disappearance of radioactivity from the …
