通过分析包含两个春小潮周期的30天时间序列，确定了潮间带微型底栖植物生物量的短期变化特征。每天在每个昼夜暴露期的开始和结束时测量叶绿素a浓度。微藻生物量表现出可预测的净增加，在昼夜曝光由于一个积极的生产损失平衡。此外，我们的数据系列表明，在环境干扰后，即使生物量大幅下降，它很快收敛到其初始的稳态振荡模式。这项研究支持一些基本属性的动力学microphytobenthic生物量，在我们以前预测的初级生产力的数学模型。
The short-term variability of intertidal microphytobenthic biomass was characterized by analysing a 30-day time series encompassing two spring–neap tide cycles. Chlorophyll-a concentration was measured every day at the beginning and at the end of every diurnal exposure periods. Microalgal biomass exhibited predictible net increases during diurnal exposures due to a positive production-loss balance. In addition, our data series shows that after an environmental disturbance, even though biomass decreased strongly, it converged quickly back to its initial steady-state oscillation pattern. This study supports some fundamental properties of the dynamics of microphytobenthic biomass, as previously predicted in our mathematical model of primary production.
