Environmental and phytoplankton parameters were explored at nine stations located along a large scale (3188 km) east–west longitudinal transect (4°95′E–32°67′E) of the Mediterranean Sea. The trend analysis confirmed statistically significant decrease mean temperatures salinities an increase nutrients (P-PO4 N-NO3), chlorophyll α, primary productivity cell concentrations. A total 216 species identified: 48 diatoms, 112 dinoflagellates 56 coccolithophores. On basis this analysis, structure...
A few studies on the excretion of organic matter by marine phytoplankton in culture have been reported (Guillard & Wangersky, 1958; Wangersky Guillard, 1960; Stewart, 1963; Hellebust, 1965). Eppley Sloan (1965) extensive Skeletonema costatum (Greville) Cleve cultures as they approached senescence and emphasized that is inversely proportional to physiological activity cells. Hellebust demonstrated release high amounts (up 38% carbon assimilated) Sk. cells exposed low light intensities. It...
