Periphyton and Associated Environmental Data Relative from Samples Collected from the Greater Everglades, Florida, USA from September 2005 to November 2014

This data package contains peripihyton and environmental data collected annually during the wet season between 2005 and 2014 from sites distributed throughout the greater Everglades ecosystem. This project is part of the Comprehensive Everglades Restoration Program's Monitoring and Assessment Plan intended to document baseline variability in periphyton attributes for assessing the effectiveness of restoration projects. A total of 200 primary sampling units (PSU) of 800 m x 800 m are nested in 32 landscape units and each year, random coordinates are 'drawn' within each PSU and one sampleable draw is visited in each. Sampled periphyton is processed for diatoms, slides are prepared, and 500 frustules are enumerated and identified to the lowest possible taxonomic resolution per slide. Taxon abundances are then relativized to the total count. These data accompany environmental, periphyton biomass, and soft algal abundance datasets.

本数据集包含2005年至2014年湿季每年采集的周丛生物（periphyton）与环境数据，采样点分布于大沼泽地生态系统全域。
本项目隶属于大沼泽地综合修复计划（Comprehensive Everglades Restoration Program）的监测与评估计划，旨在记录周丛生物属性的基线变异性，以评估修复工程的实施成效。
共计200个面积为800米×800米的初级采样单元（PSU）嵌套于32个景观单元中；每年在每个初级采样单元内随机抽取坐标，并对每个单元中一个可采样的抽取点进行实地采样。
采集的周丛生物样本将被用于硅藻分析：制备载玻片后，每张载玻片计数并鉴定至最低可行的分类学层级，总计计数500个硅藻壳。
随后将各分类单元的丰度换算为占总计数的相对比例。
本数据集配套包含环境数据、周丛生物生物量数据以及软质藻类丰度数据集。
