Konza Prairie site, station Konza Prairie LTER watershed 004b, study of animal abundance of Rattus norvegicus in units of numberPerTransectLinePer4DayTrapSeason 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 Konza Prairie (KNZ)
contains animal abundance of Rattus norvegicus measurements in numberPerTransectLinePer4DayTrapSeason units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（Jornada盆地长期生态研究网，美国农业部农业研究局Jornada试验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究网，美国农业部林务局卢奎洛试验林）于2004年发起，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，核心目标是提升长期生态数据的可获取性与应用效率。截至目前，已有约50个州级及联邦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）资助的站点，另有众多高校参与其中。EcoTrends项目的数据集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访问工作。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过人工与自动两种处理模式完成更新。该网络门户由Jornada LTER与LTER网络办公室联合打造。本次提供的康扎草原（Konza Prairie, KNZ）数据集包含褐家鼠（Rattus norvegicus）的种群丰度实测数据，计量单位为numberPerTransectLinePer4DayTrapSeason，且已聚合至年度时间尺度。
