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

EcoTrends项目于2004年由Debra Peters博士（乔纳达盆地长期生态研究站（Long-Term Ecological Research，简称LTER），美国农业部农业研究服务局（USDA-ARS）乔纳达实验牧场）与Ariel Lugo博士（卢奎略长期生态研究站（Long-Term Ecological Research，简称LTER），美国农业部林务局（USDA-FS）卢奎略实验森林）创立，旨在支持长期生态数据集的收集与分析工作。该项目为一项大型综合研究计划，核心目标是提升长期生态数据的可获取性与使用率。目前，共有约50个由州政府与联邦政府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（Long-Term Ecological Research，简称LTER）站点，以及由美国农业部农业研究服务局（ARS）、美国农业部林务局（USDA-FS）、美国能源部、美国地质调查局（USGS）及众多高校资助的站点。EcoTrends项目的相关数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式网络应用程序，可为用户提供持续的数据汇编与数据获取服务。作为长期生态研究溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture，简称PASTA）的组成部分，持续推进的数据汇编工作将通过人工与自动两种处理方式进行更新。该网络门户由乔纳达盆地LTER站与LTER网络办公室联合开发。以下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贝氏狼牙脂鲤（Belonesox belizanus）种群密度实测数据，且已按年度时间尺度完成聚合。
