Sevilleta site, station Rio Salado Larrea Study Site, study of animal abundance of Chaetodipus intermedius 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 Chaetodipus intermedius measurements in numberPerTrappingWeb units
and were aggregated to a yearly timescale.

EcoTrends项目由德布拉·彼得斯博士（若塔纳盆地LTER（Long-Term Ecological Research），美国农业部农业研究局（USDA-ARS）若塔纳实验牧场）与阿里尔·卢戈博士（卢奎洛LTER（Long-Term Ecological Research），美国农业部森林局（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作，核心目标为提升长期生态数据的可获取性与利用率。
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，其中涵盖全部26个LTER站点，以及由美国农业部农业研究局（ARS）、美国农业部森林局、美国能源部、美国地质调查局（US Geological Survey）及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。该网络门户依托交互式Web应用，支持用户持续开展数据整合与数据获取工作。
作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, 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。
该网络门户由若塔纳LTER站点与LTER网络办公室合作开发。
本次提供的塞维利塔（Sevilleta, SEV）数据集包含中间更格卢鼠（Chaetodipus intermedius）的种群丰度数据，计量单位为"每个诱捕网的数量"，且已按年尺度进行聚合。
