Abstract

We examined energy flow and nitrogen turnover in a highly eutrophic lake in Chile. Carbon fixation varied seasonally between 25–450 mg C m−2 h−1 in the photic zone, andca. 6.25×106 kg C were fixed in the lake during 1980. Nitrogen turnover in the phytomas wasca. 1.04×106 kg N yr−1 based on an arbitrary C∶N ratio of 6.0.

Resumen

En un lago muy eutrofizado en Chile se estudiaron el flujo de energía y la tasa de recambio de nitrógeno. La fijación de carbono mostró variaciones estacionales entre 25 y 450 mg C m−2 h−1 en la zona fótica; cerca de 6,25×106 kg C fueron fijados durante 1980. El recambio de nitrógeno, calculado asumiendo una relación arbitraria C∶N=6,0, fue de 1,04×106 kg N año.
