North Temperate Lakes LTER: Benthic Macroinvertebrates 1981 - current

Macroinvertebrates are collected from selected shoreline and deep water locations in three primary research lakes (Crystal, Sparkling, and Trout lakes) in the Trout Lake area using modified Hester-Dendy samplers. Samplers are placed at fyke net and gill net locations in August and retrieved 3-4 weeks later. Macroinvertebrates are preserved in ethanol. This dataset contains counts of various groups of macroinvertebrates identified from specific samples. The majority of the identifications are at the genus level. The data table "Benthic Macroinvertebrate Codes" identifies the taxonomic group represented by each group code. Taxonomic references: Ecology and Classification of North American Freshwater Invertebrates, Edited by James H Thorp and Alan P Covich, Academic Press, Inc, 1991; Aquatic Insects of Wisconsin, William L Hilsenhoff, Natural History Museums Council, University of Wisconsin-Madison (1995). No lakes were sampled in 2020 or 2021. Sampling Frequency: annually. Number of sites: 17.

研究人员采用改良型赫斯特-登迪采样器（modified Hester-Dendy samplers），于鳟湖区域内的3座核心研究湖泊——水晶湖（Crystal Lake）、闪光湖（Sparkling Lake）与鳟湖（Trout Lake）——的选定岸线及深水点位采集大型无脊椎动物（Macroinvertebrates）。采样器于8月布设至袋网（fyke net）与刺网（gill net）的布设点位，3至4周后回收。采集所得的大型无脊椎动物以乙醇进行固定保存。本数据集包含从各专属样本中鉴定得到的多类大型无脊椎动物的计数数据，绝大多数鉴定工作开展至属级分类水平。名为《底栖大型无脊椎动物编码表》（Benthic Macroinvertebrate Codes）的数据表明确了各分组代码所对应的分类类群。分类学参考文献如下：《北美淡水无脊椎动物生态学与分类》（Ecology and Classification of North American Freshwater Invertebrates），James H Thorp与Alan P Covich主编，学术出版社（Academic Press, Inc），1991年；《威斯康星州水生昆虫》（Aquatic Insects of Wisconsin），William L Hilsenhoff著，威斯康星大学麦迪逊分校自然历史博物馆理事会（Natural History Museums Council, University of Wisconsin-Madison），1995年。2020年与2021年未开展任何湖泊采样工作。采样频率：每年1次。采样点位数量：17个。
