Sevilleta site, station Five-Points Grass Study Site, study of animal abundance of Peromyscus boylii 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 Peromyscus boylii measurements in numberPerTrappingWeb units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约纳盆地长期生态研究站点（Jornada Basin LTER）、美国农业部农业研究服务局约纳试验牧场（USDA-ARS Jornada Experimental Range））与阿里尔·卢戈博士（卢基略长期生态研究站点（Luquillo LTER）、美国农业部林务局卢基略试验林（USDA-FS Luquillo Experimental Forest））于2004年创立，旨在支持长期生态数据集的采集与分析工作。
该项目为大型综合研究项目，核心聚焦于提升长期生态数据的可获取性与复用效率。目前共有约50个由州级与联邦政府资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及美国农业部农业研究服务局（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）资助的站点，另有众多高校站点加入。
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络应用程序，支持用户持续开展数据汇编与获取工作。
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。
该网络门户由约纳LTER站点与LTER网络办公室合作开发。
本次提供的塞维列塔（Sevilleta, SEV）数据集包含鹿鼠（Peromyscus boylii）的种群丰度数据，统计单位为numberPerTrappingWeb，且已按年度时间尺度进行聚合。
