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 …

We present an overview of the plankton studies conducted during the last 25 years in the
epipelagic offshore waters of the Mediterranean Sea. This quasi-enclosed sea is …

Acclimation of the photosynthetic apparatus to changes of irradiance, temperature and
nutrient availability, involving regulation of the chlorophyll a: carbon ratio (g), is a universal …

The most fundamental questions such as whether a cell is alive, in the sense of being able
to divide or to form a colony, may sometimes be very hard to answer, since even axenic …

Using a sampling grid of 67 stations, the influence of basin‐wide and subbasin‐scale
circulation features on phytoplankton community composition and primary and new …

Based on existing knowledge about phytoplankton responses to nutrients and food size
spectra of herbivorous zooplankton, three different configurations of pelagic food webs are …

The smallest marine phytoplankton, collectively termed picophytoplankton, have been
routinely enumerated by flow cytometry since the late 1980s during cruises throughout most …

In early 1998, a toxic red tide devastated the fish farming industry in Hong Kong. In response
to the attention given to this event by the general public and the fisheries industry, the …

The Eastern Mediterranean Sea (EMS) is a relatively small ocean basin with an unusually
high nitrate to phosphate ratio in the deep waters (∼ 28: 1). As a consequence, the typical …

Copepods, cladocerans and tunicates form major groups of herbivorous mesozooplankton.
The former two are found in fresh and marine waters, while the latter are restricted to marine …
