WAMSI Node 1.1.2 - Spatial and Seasonal Variability in Microphytobenthos and Macroalgal Primary Productivity and Nutrient Dynamics

Despite the apparent importance of microphytobenthos and macroalgal populations as primary producers, primary productivity data and particularly data investigating the controls on primary productivity in WA shelf waters are sparse. We have investigated microphytobenthoc and macroalgal primary productivity in Marmion Lagoon by measuring oxygen evolution during a number of targeted incubations.尽管微型底栖藻类（microphytobenthos）与大型藻类（macroalgal）种群作为初级生产者的重要性不言而喻，但当前西澳大利亚（WA）陆架海域的初级生产力数据，尤其是针对初级生产力调控机制的研究数据仍较为匮乏。本研究通过开展多组针对性培养实验、测定光合放氧量的方式，对马米恩泻湖（Marmion Lagoon）内的微型底栖藻类与大型藻类初级生产力展开了调查。
