WAMSI Node 3.2.2b - Diversity, abundance and distribution of intertidal invertebrate species in the Ningaloo Marine Park - Small giant clams (Tridacna maxima)

A quantitative pilot study of the composition of the benthic community of macro-invertebrates on intertidal rocky platforms was undertaken to: \n\na) provide detailed information on variation in biodiversity along the length of the Ningaloo Marine Park; and \nb) determine the appropriate design of a monitoring protocol powerful enough to determine predefined levels of change. \n\nAs part of the larger WAMSI Node 3.2.2b study there was specific sampling of small giant clams (Tridacna maxima). Data available includes\n\n1. Lengths of small giant clams (Tridacna maxima) mapped at 20 sites (3119 rows x 11 columns including identifying information for each length):\n[WAMSI3.2.2bGiantClams.csv]\n\n2. GPS readings as UTM values for locations of transects used to map positions of Tridacna maxima (giant clams) (404 rows x 6 columns, including sample identification information):\n[WAMSI3.2.2bTridacnaUTM.csv]\n\nShoreward, southern corners of Transect 1 and some others for areas where Tridacna maxima were measured as reported in Research Chapter 4.\n[WAMSI3.2.2bGiantClams.kmz]\n\n\nData files come with metadata / descriptions of the column titles and codes.

本研究为定量预试验，旨在探究潮间带岩滩大型底栖无脊椎动物的底栖群落组成，具体目标如下：
a) 详细阐明宁格罗海洋公园（Ningaloo Marine Park）沿线生物多样性的空间变化特征；
b) 确定可有效检测预设变化幅度的监测方案设计。

本研究作为更大规模WAMSI Node 3.2.2b研究的组成部分，针对小型大砗磲（Tridacna maxima）开展了针对性采样。可用数据集如下：

1. 于20个采样点采集的小型大砗磲体长数据（共3119行、11列，包含每条体长记录的标识信息）：[WAMSI3.2.2bGiantClams.csv]
2. 用于标定大砗磲分布样带位置的UTM格式GPS坐标数据（共404行、6列，包含样品标识信息）：[WAMSI3.2.2bTridacnaUTM.csv]

另有匹配研究第4章中所记录的大砗磲测量区域的样带地理数据（涵盖样带1向岸侧、南侧拐角及其他相关区域）：[WAMSI3.2.2bGiantClams.kmz]
