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

EcoTrends项目于2004年由黛布拉·彼得斯博士（乔达纳盆地长期生态研究站点，Long-Term Ecological Research, 简称LTER；美国农业部农业研究局（USDA-ARS）乔达纳实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站点，Long-Term Ecological Research, 简称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。
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复用率。目前共有约50个州级与联邦资助的研究站点参与并向本项目贡献数据，其中涵盖全部26个长期生态研究（LTER）站点，以及美国农业部农业研究局（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，为用户提供数据整合与可访问服务，保障数据整理与共享工作的持续开展。作为长期生态研究站点溯源感知综合跟踪架构（PASTA）的组成部分，日常数据整合工作通过手动与自动两种处理方式完成更新。
该网络门户由乔达纳LTER站点与LTER网络办公室联合开发。本次提供的佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE）数据集，包含斑点太阳鱼（Lepomis punctatus）的种群密度实测数据，单位为每平方米个体数，且已按年度时间尺度完成聚合。
