Macquarie Island stream invertebrate survey 2016

This data record is for stream invertebrate samples collected by Melissa Houghton from 13 site across Macquarie Island in December 2016. At each site, 5 biotic kick-samples and water quality measurements were collected and site photographs taken. Sites were originally established by Richard Marchant in 1992 (ASAC_555) and were resurveyed in 2008 and 2010 (ASAC_2918 & AAS_3261). Site numbers are as described for previous survey periods and for the 2016 survey included 1-11, 13 and 15. The biotic samples were returned to Australia for taxonomic sorting and identification by Richard Marchant. Site photographs were assessed by Jane Wasley for vegetation status (recovery from grazing) relative to matched photographs taken in previous years. Some files attached to this record also include compiled data from previous surveys in 1992, 2008 and 2010. Three excel files are provided pertaining to: 1. Stream invertebrate taxa; 1992-20162. Water quality; EC and turbidity for 2008 and 20163. Vegetation; categorisation of change; grazing and recovery status 2008 and 2016See parent and associated child records for further information.

本数据集记录的是2016年12月梅利莎·霍顿（Melissa Houghton）于麦夸里岛（Macquarie Island）13个采样点采集的溪流无脊椎动物（stream invertebrate）样本。每个采样点均完成5组生物踢扫采样（kick-sample）、水质测量，并拍摄采样点现场照片。该批采样点最初由理查德·马钱特（Richard Marchant）于1992年设立（编号ASAC_555），并分别于2008年、2010年完成复勘（对应编号ASAC_2918与AAS_3261）。采样点编号沿用既往调查的命名规则，2016年本次调查覆盖的编号为1-11、13及15。本次采集的生物样本已送回澳大利亚，由理查德·马钱特完成分类学分拣与物种鉴定。简·韦斯里（Jane Wasley）对采样点照片进行了评估，结合往年拍摄的匹配照片，分析植被受放牧后的恢复状况。本记录附带的部分文件还整合了1992年、2008年及2010年历次调查的相关数据。本次共提供3个Excel文件，分别对应以下内容：1. 1992-2016年溪流无脊椎动物类群数据；2. 2008年与2016年的水质数据（电导率与浊度）；3. 2008年与2016年的植被变化分类、放牧与恢复状态数据。更多详细信息请参阅父级及关联子级记录。
