Nutrient limitation of phytoplankton in Chesapeake Bay
This paper presents evidence of a seasonal shift from P to N as the nutrient limiting the accumulation of algal biomass in Chesapeake Bay. Following the winter/spring maximum in freshwater runoff, (1) the ratio of dissolved inorganic nitrogen to soluble reactive phosphorus (DIN/PO,) was greater than the N/P of algal biomass; (2) alkaline phosphatase activity was high; (3) phosphate turnover tim...
متن کاملFeasibility of cattle urine as nutrient medium for the microalgal biomass production
Thenutrient medium used for the cultivation of microalgae adds more cost to its value-added product as well as the commercial scale application. Therefore in this study, focused feasibility of cattle urine as a cheap source of nutrients for microalgal growth, because, it contains various minerals and economical which may support the growth of microalgae and reduce the medium cost. To check this...
متن کاملEarly Holocene mass-movements in southeastern Hudson Bay and their possible triggering by postglacial seismicity
Glacio-isostatically induced seismic activity is recognized to play a major role in triggering submarine mass-movements along formerly glaciated continental margins. Ice load removal is known to cause fault instability and generate many earthquakes in these regions immediately after deglaciation. With rates of forced regression of ~7 m/100 yr at time of deglaciation (8-7 ka BP), southeastern Hu...
متن کاملProtein measurements of microalgal and cyanobacterial biomass.
The protein content of dry biomass of the microalgae Porphyridium cruentum, Scenedesmus almeriensis, and Muriellopsis sp. and of the cyanobacteria Synechocystis aquatilis and Arthrospira platensis was measured by the Lowry method following disruption of the cells by milling with inert ceramic particles. The measurements were compared with the Kjeldahl method and by elemental analysis. The nitro...
متن کاملIntense stratification leads to phytoplankton nutrient limitation and reduced microzooplankton grazing in the southeastern Bering Sea
During July and August 2004, we used the seawater dilution technique to investigate relationships stratified. Compared with previous observations in the subarctic Pacific and Bering Sea, mixed-layer phytoplankton growth rates were typical (average 0.35d ) while microzooplankton grazing rates were low (average 0.13 d ). Phytoplankton growth rates were strongly nutrient-limited, increasing to an ...
