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

EcoTrends项目由黛布拉·彼得斯博士（约那盆地长期生态研究网[Long-Term Ecological Research, 简称LTER]，美国农业部农业研究服务局[USDA-ARS]约那实验牧场）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]卢奎洛实验森林）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。该项目是一项大型综合研究工程，核心目标为提升长期数据的可获取性与利用效率。目前，共有约50个州级与联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中包含全部26个长期生态研究（LTER）站点，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Web应用，支持用户持续开展数据整合与数据获取操作。作为长期生态研究网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。该网络门户由约那LTER站点与LTER网络办公室联合开发。本次来自佛罗里达海岸大沼泽地（Florida Coastal Everglades, 简称FCE）的数据集，包含以每平方米个体数为单位的彼氏美洲鱥（Notropis petersoni）种群密度测量数据，且已按年际时间尺度进行聚合。
