Enzyme activity after drying and bedform migration in the Spree River in 2018...

Sandy streambed sediments that had been exposed to either intense drying (90-day without rainfall) or bedform migration (periodically moving ripples) were placed in 250 µm mesh...将经受过极端干燥（90天无降雨）或床面形态迁移（周期性移动沙纹）作用的沙质河床沉积物，放置于250微米（µm）孔径的网筛中。
