Molecular identification of green algal balls from Dee-Why beach, Sydney, Australia

A collection of green algal balls washed up on Dee-Why beach in Sydney, Australia, in September and October 2014. These documents describe our efforts to identify the species of alga that comprise these balls using molecular biology. The summary.pdf file describes in detail what we did, and combined with the other files in this repository contains all the information necessary to replicate our analysis. To summarise our findings - we sequenced two gene regions (ITS and 18S) from each of two algal balls. All of our analyses suggest that we can unambiguously identify the species as Chaetomorpha linum (http://www.algaebase.org/search/species/detail/?species_id=222).

2014年9月至10月间，在澳大利亚悉尼迪伊威（Dee-Why）海滩冲刷上岸的绿藻球（green algal balls）集合。本数据集相关文档详述了我们借助分子生物学手段，对构成这些藻球的藻类物种进行鉴定的研究过程。本数据集仓库中的summary.pdf文件详细阐述了我们的实验流程，结合仓库内其余文件，可完整复现我们的分析工作。现将研究结果概述如下：我们从两份藻球样本中分别对两个基因区域（ITS、18S）进行了测序。所有分析结果均表明，我们可明确将该物种鉴定为线形毛丝藻（Chaetomorpha linum），详细物种信息可参考链接：http://www.algaebase.org/search/species/detail/?species_id=222。
