IISD Experimental Lakes Area LTER: Phytoplankton Abundance, Biomass, and Community Structure, 1969 – 2024

The IISD Experimental Lakes Area (IISD-ELA) LTER Phytoplankton Abundance, Biomass, and Community Structure data package provides data on phytoplankton from five long-term reference lakes (Lake 114, Lake 224, Lake 239, Lake 373, and Lake 442) in northwestern Ontario, Canada. The data package includes metadata and tabular data. Metadata include a lake information table (lake names, locations, morphometric data) and an HTML information sheet that describes the data package and includes methods, a data dictionary, and references. Tabular data include: phytoplankton biomass summarized at the Division (Cyanobacteria) or Class (chlorophyceae, euglenophyceae, chrysophyceae, bacillariophyceae, cryptophyceae, dinophyceae) level of taxonomic resolution ("Group"); phytoplankton abundance and biomass at the lowest level of taxonomic resolution (usually species level); phytoplankton species codes that act as a primary key linking the previous tables to current scientific names; and the phytoplankton trophic feeding type that partitions taxa into functional feeding groups (autotrophic, heterotrophic, mixotrophic). The data package is ongoing – updated data will be provided as data are collected from these long-term reference lakes in subsequent years. If data are not present for the lake you are interested in (e.g. if the lake was part of an experiment rather than a reference lake) please get in touch with us.

国际可持续发展研究所实验湖区（IISD Experimental Lakes Area, IISD-ELA）长期生态研究（Long-Term Ecological Research, LTER）浮游植物丰度、生物量与群落结构数据集包，收录了加拿大安大略省西北部5个长期参考湖泊（114号湖、224号湖、239号湖、373号湖及442号湖）的浮游植物相关数据。该数据集包包含元数据与表格数据两类内容。其中元数据涵盖湖泊信息表（含湖泊名称、地理位置、形态测量数据），以及一份介绍数据集包的HTML说明文档，文档中包含研究方法、数据字典与参考文献。表格数据具体包括：按分类学层级"Group"汇总的浮游植物生物量——分类学层级为门（蓝藻门Cyanobacteria）或纲（绿藻纲Chlorophyceae、裸藻纲Euglenophyceae、金藻纲Chrysophyceae、硅藻纲Bacillariophyceae、隐藻纲Cryptophyceae、甲藻纲Dinophyceae）；最低分类学层级（通常为物种层级）的浮游植物丰度与生物量数据；可作为主键的浮游植物物种编码，用于将前述表格关联至当前通用科学学名；以及浮游植物营养摄食类型数据，可将类群划分为自养型、异养型、混养型三类功能摄食类群。本数据集包为持续更新项目，后续年份采集自上述长期参考湖泊的新数据将陆续发布更新。若您所需的湖泊数据暂未收录（例如该湖泊为实验湖泊而非参考湖泊），请与我们取得联系。
