摘要:
No cause-effect relationship of light and nutrients on primary productivity was found in Lake Monroe, Indiana, using path analysis, but sufficient light was indispensable to an increase in productivity during nutrient enrichment. The lack of sufficient light can explain why primary productivity was low in December, January, February, and early March despite high levels of nutrients in the lake. Lack of significant increase in algal productivity in summer may be attributed the deficiency in available phosphate.
