Florida Coastal Everglades site, station Unknown site at Florida Coastal Everglades LTER, study of animal density of Clarias batrachus 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 Clarias batrachus measurements in numberPerMeterSquared units
and were aggregated to a yearly timescale.

EcoTrends项目由德布拉·彼得斯博士（若望盆地长期生态研究站[Jornada Basin LTER]，美国农业部农业研究局若望实验牧场[USDA-ARS Jornada Experimental Range]）与阿里尔·卢戈博士（卢奎洛长期生态研究站[Luquillo LTER]，美国农业部林务局卢奎洛实验林[USDA-FS Luquillo Experimental Forest]）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。该项目是一项大型综合研究计划，致力于提升长期数据的可获取性与利用率。目前共有约50个州政府与联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research）站点，以及由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）资助的站点与众多高校站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取，该门户通过交互式网页应用，支持用户持续开展数据汇编与数据获取工作。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，持续进行的数据汇编工作通过手动与自动两种处理方式完成更新。该网络门户由若望LTER站点与LTER网络办公室合作开发。本项来自佛罗里达海岸大沼泽地（Florida Coastal Everglades，简称FCE）的数据集，包含以numberPerMeterSquared（每平方米数量）为单位的胡鲶（Clarias batrachus）种群密度测量数据，且已按年度时间尺度进行聚合。
