Stable carbon and nitrogen isotope ratios were used to elucidate primary carbon sources and trophic relationships of the fish and shrimp community in the Klong Ngao mangrove ecosystem, southern Thailand. There were no significant differences in isoto

Stable carbon (δ13C) and nitrogen (δ15N) isotopes were used to elucidate primary food sources and trophic relationships of organisms in Khung Krabaen Bay and adjacent offshore waters. The three separate sampling sites were mangroves, inner bay and

Stable carbon isotope ratios (δ13C) and C/N atomic ratio {(C/N)a} were used to investigate the sources and fate of organic matter in Khung Krabaen Bay, Thailand (KKB) and to assess the effect of shrimp pond effluent on the KKB system. Five major sou

Recent studies point out that dissolved iron in seawater is bound to strong organic complexes that have stability constants consistent with microbially produced siderophores. In the present study, the growth and iron uptake of the coastal marine diat

Vertical distributions of size-fractionated Fe concentrations ( 0.22-μm fractions) and Fe(III) hydroxide solubilities were studied during a spring phytoplankton bloom (February to April, 1995) in Funka Bay, Japan. “Soluble Fe” (

Time series observations over 36 h were carried out in Funka Bay, Japan, to complement a 6 yr nutrient-dynamics study during a diatom spring bloom, especially focusing on nitrate and silicate as limiting nutrients. At the beginning of the study, nutr

Crustose coralline algae dominates coastal rocky shores (crust-dominated community) in certain world coastal zones after the disappearance of kelp forest community. Local fisheries suffer greatly when this occurs. Well known ecological hypothese to e

The concentrations of Cu, Ni and Cd were determined in Funka Bay during a spring phytoplankton bloom, consisting of diatoms. Just after the bloom, both dissolved Cd and nutrients were removed in the euphotic zone. However, the removal ratio of Cd to

The effects of riverain iron and nutrient inputs on phytoplankton growth in Kesennuma Bay were studied. The effects of iron and fulvic acid-iron complex additions on phytoplankton growth were studied in iron-enriched and -limited culture experiments
