Florida Coastal Everglades site, station Shark Slough Trexler Site 37C, study of animal abundance of Cyprinodon variegatus 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 Cyprinodon variegatus measurements in numberPerEffort units and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（乔尔纳达盆地长期生态研究网[Long-Term Ecological Research, LTER]、美国农业部农业研究局[USDA-ARS]乔尔纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究网[LTER]、美国农业部林务局[USDA-FS]卢奎洛实验林）于2004年创立，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，核心目标是提升长期生态数据的可获取性与应用价值。目前，约有50个州立及联邦资助的研究站点参与并贡献至EcoTrends项目，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USDA-ARS、美国农业部林务局、美国能源部、美国地质调查局（USGS）资助的站点与众多高校站点。EcoTrends项目的数据可通过探索性Web门户（http://www.ecotrends.info）获取。该门户依托交互式Web应用程序，支持用户持续开展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，简称PASTA）的组成部分，其持续进行的数据整合工作通过手动与自动两种处理方式完成更新。本Web门户为乔尔纳达LTER与LTER网络办公室的合作成果。本次发布的佛罗里达海岸大沼泽地（FCE）数据集，包含斑节鳉（Cyprinodon variegatus）的种群丰度实测数据，其度量单位为numberPerEffort，且已被聚合至年度时间尺度。
