Competition of bloom-forming marine phytoplankton at low nutrient concentrations.
Competition of three bloom-forming marine phytoplankton (diatom Skeletonema costatum, and dinoflagellates Prorocentrum minimum and Alexandrium tamarense) was studied through a series of multispecies cultures with different nitrate (NaNO3) and phosphate (NaH2PO4) levels and excess silicate to interpret red tide algae succession. S. costatum outgrew the other two dinoflagellates in nitrate and ph...
متن کاملPhytoplankton growth and stoichiometry under multiple nutrient limitation
Phytoplankton growth and stoichiometry depend on the availability of multiple nutrients. We use a mathematical model of phytoplankton with flexible stoichiometry to explain patterns of phytoplankton composition in chemostat experiments and nutrient drawdown dynamics that are found in the field. Exponential growth and equilibrium represent two distinct phases, each amenable to mathematical analy...
متن کاملNutrient limitation of phytoplankton growth in central plains reservoirs, USA
Historically, phosphorus has been considered to be the primary nutrient limiting phytoplankton growth in freshwater ecosystems. We tested this hypothesis in 19 Kansas reservoirs located within the Central Plains region, USA. Bioassay experiments were conducted to assess growth-rate limitation by nitrogen (N), phosphorus (P) and nitrogen and phosphorus (N and P). The addition of P alone rarely i...
متن کاملIdentification of Algae-Nutrient Relationships
Fundamental relationships are presented showing that the probability distribution of chlorophyll a (Chla) depends on both the distribution of Chla conditioned on TN and TP, and the distribution of TN conditioned on TP. It is further shown that simplified forms of these distributions can be identified using the non-parametric Spearman correlations between Chla, TN, and TP. Based on these fundame...
