Light effects on phytoplankton morphometric traits influence nutrient utilization ability

Allometric scaling and taxonomic variation in nutrient utilization traits and maximum growth rate of phytoplankton

Nutrient utilization traits can be used to link the ecophysiology of phytoplankton to population dynamic models and the structure of communities across environmental gradients. Here we analyze a comprehensive literature compilation of four traits: maximum nutrient uptake rate; the half-saturation constant for nutrient uptake; the minimum subsistence quota, measured for nitrate and phosphate; an...

Phytoplankton nutrient competition under dynamic light regimes

Many physiological processes in phytoplankton, including nutrient uptake, vary on a number of temporal scales. Experiments show that the daily cycle in irradiance affects nutrient uptake rates. We used a Droop-based model of resource competition to investigate how diel variability in nutrient uptake influences phytoplankton competition and community structure. The analytical approximation we de...

Modelling the interacting effects of nutrient uptake, light capture and temperature on phytoplankton growth

In aquatic ecosystems, autotrophs often grow at suboptimal temperatures, nutrient concentrations and light conditions. Laboratory experiments have demonstrated an interaction between some of these limiting factors in phytoplankton (Rhee and Gotham, 1981), seagrass (Masini and Manning, 1997) and macroalgae (Kirk, 1994). Capturing the interaction of nutrient uptake rates, light capture and temper...
