- Abstract
Abundance of Pithophora oedogonia akinetes displayed seasonal changes, being greatest in winter and lowest in summer. Akinete abundance showed significant (P < 0.001) negative correlations with photoperiod (r = -0.53) and water temperature (r = -0.75) during the period February 1978 through June 1979. Experiments in which akinete germination was studies in response to manipulations of nutrients (NO[SUB3]-N and PO[SUB4]-P), photoperiod and temperature indicated that temperature was the primary factor regulating the timing of the vernal flush of akinete germination observed in Surrey Lake.
