Florida Coastal Everglades site, station Shark Slough Trexler Site 23B, study of animal density of Cichlasoma bimaculatum 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 Cichlasoma bimaculatum measurements in numberPerMeterSquared units and were aggregated to a yearly timescale.

EcoTrends项目由德布拉·彼得斯博士与阿里尔·卢戈博士于2004年发起创立，德布拉·彼得斯博士供职于约拿盆地长期生态研究（Long-Term Ecological Research, LTER）站点、美国农业部农业研究服务局（USDA-ARS）约拿实验牧场，阿里尔·卢戈博士供职于卢奎约长期生态研究（Long-Term Ecological Research, LTER）站点、美国农业部林业局（USDA-FS）卢奎洛实验林，本项目旨在支撑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，核心目标在于提升长期生态数据的可获取性与应用价值。目前共有约50个州级与联邦资助的研究站点参与本项目并贡献数据，其中涵盖全部26个LTER站点，以及由美国农业部农业研究服务局（USDA ARS）、美国农业部林业局（USDA FS）、美国能源部、美国地质调查局（US Geological Survey, USGS）及众多高校资助的研究站点。EcoTrends项目的公开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Web应用，为用户提供持续的数据整合与数据获取服务。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，本项目的持续数据整合工作通过人工与自动处理相结合的方式完成更新迭代。该网络门户由约拿盆地LTER站点与LTER网络办公室联合开发运营。本次发布的佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE）数据集，包含以每平方米个体数为单位的双斑丽体鱼（Cichlasoma bimaculatum）种群密度测量数据，且所有数据已按年际时间尺度完成聚合整理。
