The minute photosynthetic prokaryote Prochlorococcus, which was discovered about 10
years ago, has proven exceptional from several standpoints. Its tiny size (0.5 to 0.7 μm in …

In reviewing this subject, it became clear to me that plankton ecologists fallout into two
groups: Those who delight in finding the patterns in nature that can be explained by size …

Fluorescent oligonucleotide hybridization probes were used to label bacterial cells for
analysis by flow cytometry. The probes, complementary to short sequence elements within …

The novel dye SYBR Green I binds specifically to nucleic acids and can be excited by blue
light (488-nm wavelength). Cell concentrations of prokaryotes measured in marine samples …

Ocean color satellites have provided a synoptic view of global phytoplankton for over 25
years through near surface measurements of the concentration of chlorophyll a. While …

The recent discovery of photosynthetic picoplankton has changed our understanding of
marine food webs1. Both prokaryotic2, 3 and eukaryotic4, 5 species occur in most of the …

Photosynthetic prokaryotes evolving oxygen are a major component of oceanic ecosystems.
The diversity ofthese micro-organisms in the picoplanktonie fraction of open oceans appears …

The cyanobacterium Prochlorococcus, is the dominant oxygenic phototroph in the tropical
and subtropical regions of the world's oceans,,. It can grow at a range of depths over which …

This 1989 book deals with the physical and chemical properties found in algae of different
types (blue-green, red, golden-brown, yellow-green, brown and green). Methods used for …

For many years, a small but dedicated group of scientists have been using flow cytometry for
the evaluation of marine microorganisms. One of these scientists now provides us with a …
