Patea River periphyton

Five replicate quantitative periphyton samples (415 mm2) were collected from the edge and mid-stream in a riffle of the Patea River. Water depth 0.3-0.8 m at time of sampling. The samples were pooled for taxonomic analysis. The objective was to characterise periphyton biomass and community composition at the site, which was below the Patea Dam and experienced low levels of dissolved oxygen. Note that the exact day of sampling is unknown.从帕蒂河（Patea River）一处急流浅滩的河岸边缘与河道中段，采集了5份定量重复着生生物（Periphyton）样本，单份样本采样面积为415平方毫米。采样时测点水深为0.3至0.8米。将所有采集样本混合后开展分类学分析。本研究旨在表征该采样点位的着生生物生物量与群落组成，该点位位于帕蒂大坝下游，水体溶解氧含量偏低。请注意，本次采样的具体日期不详。
