North Temperate Lakes site, station Fish Lake, study of animal abundance of Catostomus commersonii in units of numberPerEffort on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from North Temperate Lakes (NTL) contains animal abundance of Catostomus commersonii measurements in numberPerEffort units and were aggregated to a yearly timescale.EcoTrends项目于2004年由德布拉·彼得斯博士（约拿盆地长期生态研究站点，USDA-ARS约拿实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站点，USDA-FS卢奎洛实验森林）创立，旨在支撑长期生态数据集的采集与分析工作。本项目为大型综合研究计划，核心目标在于提升长期生态数据的可获取性与利用效率。目前已有约50个由州政府及联邦政府资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research，以下简称LTER）站点，以及由美国农业部农业研究服务局（ARS）、美国农业部森林服务局、美国能源部、美国地质调查局（USGS）及众多高校资助的相关站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取，该门户依托交互式网页应用，为用户持续提供数据汇编与数据访问服务。作为长期生态研究溯源感知综合跟踪架构（PASTA）的组成部分，本项目的持续数据汇编工作通过人工与自动两种处理方式完成更新。本网络门户由约拿LTER站点与LTER网络办公室联合共建。本次来自北温带湖泊（North Temperate Lakes，简称NTL）的数据集，包含了普通吸口鲤（Catostomus commersonii）的种群丰度数据，计量单位为每采样 effort 个体数（numberPerEffort），且已按年度时间尺度完成聚合。
