competition between unicellular N and non-N fixing cyanobacteria

MSAE grows best with N:P 103 (mol:mol), cellular ratio of 46

APFA - N:P 53 is optimal

bio-volume from counts in an inverted microscope

seasonal succession patterns

APFA dominance during times that had 1/3 less NO3 than during MSAE dominance - NO3 maybe the most influential nutrient

MSAE (PCC7806), APFA(HAB 176)and Cuylindrospermospsis raciborskii (HAB 151)

Cr had higher cartenoids, higher Pm, higher alpha, and max ETR, higher AlkPase and lower light compensation Ic suggest

M. aeruginosa UTEX 2061 K1/2 = 0.016 mg N L-1 umax = 0.366 day-1

Cyclotella sp CCAP 1070/4 K1/2 = 0.234 ug N L-1 umax = 0.418 day -1

Cyclotella completely dominated in NO3 range 0.5 to 2.5 mg N L-1 which was attributed storage as well as NO3 uptake ratees
