Two main parameters that structure the marine ecosystem by affecting species distribution,
abundance, community structure, timing of major life cycle events, and trophic state of the …

Biogeochemical cycles of carbon transformation throughout the euphotic zone of the sea are
controlled by physical processes, eg, daily thermocline, variation in solar irradiance …

The seasonal evolution of the species composition and depth of the deep maximum of
phytoplankton (DPM) in the Black Sea has been studied. Vertical series of phytoplankton …
