The biological and biogeochemical consequences of phosphate scavenging onto phytoplankton cell surfaces
The biological and biogeochemical consequences phosphate scavenging phytoplankton cell surfaces
2005/9/13
Phytoplankton carbon (C) and nitrogen (N) content is commonly normalized to phosphorus (P) quotas as Redfield C:N: P ratios. We examined how surface-bound P pools affect Redfield stoichiometry and P u...
Diel variations in the photosynthetic parameters of Prochlorococcus strain PCC 9511: Combined effects of light and cell cycle
