Macquarie Island Poa annua soil samples 2010-11: Springtail abundance and habitat

In 2010-11 70mm soil cores were collected from locations at Macquarie Island rich in the invasive plant Poa annua. The cores were collected at 22 sites, with 10 samples per site. Processing and identification of species was completed in 2016.This file contains three spreadsheets: site descriptions, complete sample descriptions and abundance of springtail species at the sites.The work was carried as part of Australian Antarctic Science (AAS) Project 4024 and is currently being written up into several papers.The 'Quad veg' column gives the percentage vegetation cover in the one metre square quadrat. The 'sample veg' column gives the percentage vegetation cover in the 70mm soil core. The numbers in these columns are percentages and the letters are abbreviations for vegetation types:pa = Poa annua, cal = Callitriche sp., ttg = tall tussock grassland (Poa foliosa), sg = short grassland (range of species), colo = Colobanthus spp.In the 'rabbit presence' column 1 means there was evidence of rabbit presence in the quadrat and 0 means otherwise.

2010至2011年，研究人员于麦夸里岛（Macquarie Island）入侵植物早熟禾（Poa annua）分布密集的区域采集70毫米深度的土壤岩心。本次采样共布设22个样地，每个样地采集10份样品。物种处理与鉴定工作于2016年完成。本数据集包含三张电子表格，分别为样地基本信息表、完整样本信息表以及样地内弹尾虫（springtail）物种丰度表。本研究为澳大利亚南极科学（Australian Antarctic Science, AAS）项目4024的组成部分，目前相关成果正整理为多篇学术论文。"Quad veg"列记录1平方米样方内的植被盖度百分比；"sample veg"列记录70毫米土壤岩心对应的植被盖度百分比。两列数值均为百分比占比，字母缩写对应植被类型如下：pa为早熟禾（Poa annua），cal为水马齿属（Callitriche sp.），ttg为高大丛生草原（福氏早熟禾，Poa foliosa），sg为短生草原（包含多种物种），colo为漆姑草属（Colobanthus spp.）。在"rabbit presence"列中，数值1代表样方内存在兔类活动痕迹，数值0代表无相关痕迹。
