Florida Coastal Everglades site, station Shark Slough Trexler Site 37A, study of animal density of Lepomis 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 Lepomis measurements in numberPerMeterSquared units
and were aggregated to a yearly timescale.

EcoTrends项目（EcoTrends Project）于2004年由德布拉·彼得斯博士（乔纳达盆地长期生态研究站[Jornada Basin LTER]，美国农业部农业研究服务局[USDA-ARS]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[Luquillo LTER]，美国农业部林务局[USDA-FS]卢奎洛实验林）创立，旨在支撑长期生态数据集的采集与分析工作。
该项目为大型综合研究计划，核心聚焦于提升长期生态数据的可访问性与复用效率。当前共有约50个州级及联邦资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究站点（Long-Term Ecological Research，LTER），以及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）资助的站点与众多高校科研站点。
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页应用，支持用户持续开展数据整合与数据获取工作。作为长期生态研究网络（LTER）溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，PASTA）的组成部分，持续推进的数据整合工作通过手动与自动两种处理方式完成更新。本网络门户由乔纳达LTER站点与LTER网络办公室联合共建。
本次发布的佛罗里达海岸大沼泽地（Florida Coastal Everglades，FCE）数据集，包含太阳鱼属（Lepomis）的动物密度数据，单位为numberPerMeterSquared，且已按年际时间尺度进行聚合。
