Florida Coastal Everglades site, station Shark Slough Trexler Site 37C, study of animal abundance of Ameiurus natalis 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 Florida Coastal Everglades (FCE) contains animal abundance of Ameiurus natalis measurements in numberPerEffort units and were aggregated to a yearly timescale.EcoTrends项目于2004年由黛布拉·彼得斯博士（乔纳达盆地长期生态研究站（LTER，美国农业部农业研究服务局乔纳达实验牧场））与阿里尔·卢戈博士（卢奎洛长期生态研究站（LTER，美国农业部林务局卢奎洛实验林））创立，旨在支持长期生态数据集的采集与分析工作。 本项目为一项大型综合研究计划，核心目标是提升长期数据的可获取性与利用效率。 目前，共有约50个由州政府及联邦政府资助的研究站点参与并为EcoTrends项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究服务局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）与众多高校资助的研究站点。 EcoTrends项目的数据集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络应用程序，支持用户持续开展数据汇编与数据获取相关工作。 作为LTER溯源感知综合跟踪架构（PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动结合的处理方式实现更新。 该网络门户由乔纳达LTER与LTER网络办公室联合开发运营。 以下来自佛罗里达海岸大沼泽地（FCE）的数据集，包含以单位采样努力量为计量单元的黄鮰（Ameiurus natalis）种群丰度测量数据，且已按年际时间尺度进行聚合。
