The ecology of Lake Nakuru (Kenya) : III. Abiotic factors and primary production.

Abiotic factors, standing crop and photosynthetic production were studied in the equatorial alkaline-saline closed-basin Lake Nakuru (cond. 10,000-160,000 μS). Meteorological conditions and abiotic factors offer suppositions for a high primary productivity: mean solar radiation is 450-550 kerg·cm·s, with little seasonal variation, regular winds circulate the lake every day and nutrient concentrations are usually high (>100 μg P-PO·l).
