| Abstract (English): |
In order to search for the distribution and differences of diatoms and other eukaryotic microplanktons at discrepant locations in the same water area so as to provide a basis for both diagnosis about drowning and inference of drowning site, we randomly selected 4 equidistant water intake points (W1, W2, W3 and W4) in the Pearl River (Guangzhou section) to collect water samples having 18S rDNA sequenced to analyze qualitatively and quantitatively those diatoms and other eukaryotic microplanktons at each water-collecting site. It was found that the average number of species of eukaryotic microplanktons including diatoms was 483.73±39.06, and the number of species in the discrepant water sampling locations was remarkably different. Meanwhile, there were significant differences among the eukaryotic microplanktons from discrepant water sampling locations. Specific diatoms were found in W1 and W4, showing Fragilaria in W1 and in W4 as Coscinodiscus, Cylindrotheca and Luticola. Moreover, Analysis revealed that all the sampling locations had their specifi c species at the species level, with W4 harboring the most amount of specifi c species totalling to 98 ones. These fi ndings suggest that the distribution and differences of the eukaryotic microplanktonic communities at different locations in the Pearl River (Guangzhou section) can be used for the inference of related death cause and drowning site. Moreover, the specifi c species at different locations in the Pearl River can provide a new insight into inference of drowning site. The eukaryotic microplanktonic communities distribute their involving species discrepantly at different locations in Guangzhou section of the Pearl River, enabling a reference and inference about related death cause and drowning site, and also establishment of the database of eukaryotic microplanktons in the Pearl River.

通过对珠江水域 (广州段) 水样进行 18S rDNA 测序分析, 探究同一水域不同地点的硅藻及其他浮游 真核微生物的分布和差异, 以期为溺死诊断和溺水地点的推断提供参考依据。在珠江水域 (广州段) 随机等 距离选取 4 个取水点采集水样, 采用 18S rDNA 测序对各取水点的硅藻及其他浮游真核微生物进行定性和定量 分析。珠江不同取水点包括硅藻在内的浮游真核微生物的种类数量 (OTU 数) 平均为 483.73±39.06 个, 但不 同取水点中的数量具有显著差异。同时, 不同取水点的微型浮游生物组成比例也存在显著差异。取水点 W1 与 W4 中存在特异的硅藻属: W1 为脆杆藻属; W4 为圆筛藻属、细柱藻属和泥生藻属。种水平上的分析显示, 所 有取水点均具有特异物种, 而以 W4 中为最多, 达 98 种。珠江水域 (广州段) 不同地点的浮游真核微生物群 落分布及其差异可为死因和溺水地点的推断提供参考, 并可用于建立珠江水域的浮游真核微生物数据库。同时, 珠江水域不同地点存在的特异物种, 也可为溺水地点的推断提供新指向。 [ABSTRACT FROM AUTHOR] |
