Konza Prairie site, station Konza Prairie LTER watershed 004b, study of animal abundance of Eritettix simplex in units of numberPer200Sweeps 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 Eritettix simplex measurements in numberPer200Sweeps units
and were aggregated to a yearly timescale.

EcoTrends项目于2004年由黛布拉·彼得斯博士（乔纳达盆地长期生态学研究站[Jornada Basin LTER]，美国农业部农业研究服务局乔纳达实验牧场[USDA-ARS Jornada Experimental Range]）与阿里尔·卢戈博士（卢奎洛长期生态学研究站[Luquillo LTER]，美国农业部林务局卢奎洛实验林[USDA-FS Luquillo Experimental Forest]）创立，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，核心致力于提升长期生态数据的可获取性与应用效能。目前共有约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，其中包含全部26个长期生态学研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究服务局（USDA ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）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。该门户依托交互式Web应用程序，支持用户持续开展数据汇编与数据共享工作。作为长期生态学研究溯源感知综合跟踪架构（LTER 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双重处理机制完成更新。本网络门户由乔纳达LTER与LTER网络办公室联合共建。
本次提供的康扎草原（Konza Prairie, KNZ）数据集，包含以每200次扫捕数量（numberPer200Sweeps）为单位的简单剑角蝗（Eritettix simplex）种群丰度测量数据，且已按年度时间尺度进行聚合。
