Macquarie Island Stream Invertebrate Taxa Data Sheets; 2008 - 2016

Stream invertebrates were surveyed at a series of sites on Macquarie Island, established in 1992 by Richard Marchant (Museums Victoria) under ASAC_555. At each site, five replicate kick samples were collected and taxon sorted and scored as presence/absence by R. Marchant. For 1992, these replicate-level data are available electronically (ASAC_555 metadata record .csv file), but for subsequent surveys in 2008, 2010 and 2016, the digitised data were entered as the sum of the five replicate samples for each site (values 0-5). These latter data were collected under ASAC_2918 (Nugegoda; 2008), AAS_3261 (Kefford; 2010) and AAS_4305 (Shaw; 2016). The data provided with this record are PDF file scans of the original hard copy, hand written, score sheets prepared by Richard Marchant as a record of replicate-level presence/absence data. Each sheet includes: - Top Left corner =     sample collection date (year and month/s) - Column 1 =         taxa names (as provided in digitised records) - Header row 1 =     site#replicate (e.g. 2#1, 2#2, 2#3, 2#4, 2#5 = site 2, replicates 1-5) - Presence =         tick - Absence =         empty cellOther feint notes can be disregarded, these are additional notes made by R. Marchant during sample processing that relate to the general condition of the samples.

本数据集针对麦夸里岛（Macquarie Island）的一系列点位开展了溪流无脊椎动物调查，该调查于1992年由理查德·马钱特（Richard Marchant，维多利亚博物馆（Museums Victoria））依托ASAC_555项目启动。每个调查点位均采集5组重复踢采样本，由R.马钱特完成类群分拣并以存在/缺失（presence/absence）状态进行评分记录。1992年的重复组数据以电子形式提供（详见ASAC_555元数据记录.csv文件）；而2008、2010、2016年的后续调查中，数字化数据为各点位5组重复样本的汇总值（取值范围为0至5）。后续三批调查分别依托ASAC_2918（Nugegoda，2008年）、AAS_3261（Kefford，2010年）及AAS_4305（Shaw，2016年）项目开展。
本数据集附带的记录为理查德·马钱特原始手写纸质评分表的PDF扫描件，该表格完整记录了重复组层面的物种存在/缺失数据。每张扫描件包含以下内容：
- 左上角区域：样本采集日期（精确至年和月）
- 第1列：类群名称（与数字化记录中的类群名称完全一致）
- 第1行表头：点位编号#重复组编号（例如2#1、2#2、2#3、2#4、2#5分别代表点位2的第1至第5组重复样本）
- 物种存在：以打勾标记表示
- 物种缺失：对应单元格为空白
其余模糊笔记可忽略，此类笔记为R.马钱特在样本处理过程中记录的样本整体状态相关的附加说明。
