Florida Coastal Everglades site, station Taylor Slough Trexler Site CPB, study of animal density of Heterandria formosa in units of numberPerMeterSquared 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 density of Heterandria formosa measurements in numberPerMeterSquared units and were aggregated to a yearly timescale.

生态趋势（EcoTrends）项目由德布拉·彼得斯博士（任职于美国农业部农业研究服务局霍尔多纳实验牧场的霍尔多纳盆地长期生态研究站（Jornada Basin LTER, USDA-ARS Jornada Experimental Range））与阿里尔·卢戈博士（任职于美国农业部林务局卢奎洛实验林的卢奎洛长期生态研究站（Luquillo LTER, USDA-FS Luquillo Experimental Forest））于2004年发起设立，旨在支持长期生态数据集的收集与分析工作。本项目为大型综合研究计划，致力于提升长期数据的可获取性与应用价值。目前，已有约50个由州政府与联邦政府资助的研究站点参与并向生态趋势项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及美国农业部农业研究服务局（USDA ARS）、美国农业部林务局（USDA Forest Service）、美国能源部（US Department of Energy）、美国地质调查局（US Geological Survey, USGS）与众多高校资助的研究站点。生态趋势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络应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，当前的数据汇编工作通过人工与自动处理相结合的方式进行更新。该网络门户由霍尔多纳长期生态研究站（Jornada LTER）与长期生态研究站网络办公室（LTER Network Office）联合开发运营。本次来自佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE）的数据集包含饰鳍花鳉（Heterandria formosa）的动物密度测量数据，单位为每平方米数量，且已按年尺度完成聚合。
