Suspended particulate organic matter was sampled monthly between June 1999 and April 2000 in the Scheldt river and estuary to investigate the seasonal and spatial patterns of δ 13 C and δ 15 N signatures. δ 15 N of suspended matter showed large seasonal variation. Minimum values ranged from -0.5%% in the freshwater zone (spring situation) to +2.3%% in the mesohaline...
The ability of phytoplankton species to initiate photo-protective mechanisms and the rates by which they do so have been suggested to be partly responsible for species succession. To examine whether this is also true in the case of diatom spring blooms preceding Phaeocystis globosa, cultures of P. globosa and Thalassiosira sp. were investigated under controlled laboratory conditions for differences...
