Kellogg Biological Station site, station Treatment 4, certified oganic, no chemical inputs, annual tillage, rotary-hoed to control weeds, study of animal abundance of Adalia bipunctata in units of numberAdultsPerYellowStickyTrap 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 Kellogg Biological Station (KBS) contains animal abundance of Adalia bipunctata measurements in numberAdultsPerYellowStickyTrap units and were aggregated to a yearly timescale.

生态趋势项目（EcoTrends Project）由黛布拉·彼得斯博士（霍纳多盆地长期生态研究站，Jornada Basin LTER；美国农业部农业研究服务局霍纳多实验牧场，USDA-ARS Jornada Experimental Range）与阿里埃尔·卢戈博士（卢奎约长期生态研究站，Luquillo LTER；美国农业部林务局卢奎约实验林，USDA-FS Luquillo Experimental Forest）于2004年创立，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，核心目标是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为生态趋势项目贡献数据，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服务局（USDA Agriculture Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（US Geological Survey, USGS）及众多高校资助的研究站点。生态趋势项目的数据可通过探索式网络门户（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整合与数据获取工作。作为LTER溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，项目的实时数据整合工作通过手动与自动两种处理方式完成更新。该网络门户由霍纳多LTER与LTER网络办公室联合开发。本数据集来自凯洛格生物站（Kellogg Biological Station, KBS），包含以每黄色粘虫板成虫数量（numberAdultsPerYellowStickyTrap）为单位的二星瓢虫（Adalia bipunctata）种群丰度测量数据，并已按年度时间尺度进行聚合。
