内容記述 The role of heterotrophic bacteria, pico-cyanobacteria and benthic cyanobacterial mats was assessed in the cycling of organic carbon and nitrogen in the Albion lagoon, Mauritius. Surveys and sampling for biological and chemical parameters were undertaken at three locations along one northern (T1) and one southern (T2) transect perpen- dicular to the shore. Low levels of nutrients showing a typical oligotrophic condition promoted by a rapid water exchange with oceanic waters characterized this lagoon. A general trend in zonation was observed from the shore with seagrass beds followed by sand and rubble, with cyanobacteria forming mats.
