Sevilleta site, station Five-Points Grass Study Site, study of animal abundance of Rodentia in units of numberPerTrappingWeb 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 Sevilleta (SEV) contains animal abundance of Rodentia measurements in numberPerTrappingWeb units and were aggregated to a yearly timescale.EcoTrends项目（EcoTrends project）于2004年由Debra Peters博士（约那盆地长期生态研究站[Jornada Basin LTER]，美国农业部农业研究局约那实验牧场[USDA-ARS Jornada Experimental Range]）与Ariel Lugo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]）发起，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，核心目标在于提升长期生态数据的可获取性与应用效率。 目前已有约50个州级与联邦资助的研究站点参与并向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, LTER）站点，以及由美国农业部农业研究局（Agricultural Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（United States Geological Survey, 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，支持用户持续开展数据汇编与数据获取操作。 作为长期生态研究溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过人工与自动两种处理方式完成更新。 该网络门户是约那LTER与LTER网络办公室的合作成果。 来自塞维利塔（Sevilleta, SEV）的下述数据集包含啮齿目（Rodentia）动物种群丰度的测量数据，统计单位为每诱捕网数量（numberPerTrappingWeb），且已按年度时间尺度进行聚合。
