    Effects of nutrient addition on phytoplankton in Lake Nakanuma, Japan

    We measured the uptake of carbon and inorganic nitrogen in nutrient-enriched water samples during 15-days incubation in summer in Lake Nakanuma, Japan. We calculated daily variations in neutral sugars and amin...

    Effects of nutrient addition on phytoplankton in Lake Nakanuma, Japan I. Changes in biochemical components

    Effects of nutrient conditions on biochemical components (sugars and amino acids) of phytoplankton were examined in Lake Nakanuma in Japan. Phosphate, ammonium and silicate were added to water samples collecte...

    Seasonal changes in neutral sugars and amino acids of particulate matter in Lake Nakanuma, Japan

    Amino acids and neutral sugars in particulate matter were measured weekly from April in 1987 to March in 1988 in Lake Nakanuma, Japan. Changes in concentrations of total amino acids and total neutral sugars co...

    Daily changes of uptake of inorganic carbon and nitrogen, and their relation to phytoplankton blooms in late spring-early summer in Lake Nakanuma, Japan

    Daily changes of inorganic carbon and nitrogen uptake were measured in May in 1986 in Lake Nakanuma, Japan. Uptake of inorganic carbon and ammonium in the light-bottle experiments in the 1 m layers, showed dai...
