Florida Coastal Everglades site, station Shark Slough Trexler Site 6B, study of animal density of Erimyzon sucetta 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 Erimyzon sucetta measurements in numberPerMeterSquared units
and were aggregated to a yearly timescale.

生态趋势（EcoTrends）项目于2004年由德布拉·彼得斯博士（约纳达盆地长期生态研究站，USDA-ARS约纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站，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。本项目是一项大型综合研究项目，核心目标为提升长期数据的可获取性与应用效率。目前，共有约50个州级与联邦资助的研究站点参与并为生态趋势项目贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究服务局（USDA Agricultural Research Service, ARS）、美国农业部林务局（USDA Forest Service）、美国能源部、美国地质调查局（United States Geological Survey, USGS）及众多高校资助的研究站点。生态趋势项目的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Web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（PASTA）的组成部分，持续进行的数据汇编工作通过人工与自动两种处理方式完成更新。该网络门户是约纳达长期生态研究站与LTER网络办公室的合作成果。本次提供的数据集源自佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE），包含以每平方米数量为单位的湖吸口鱼（Erimyzon sucetta）种群密度测量数据，且已按年度时间尺度进行聚合。
