Central Arizona - Phoenix Urban LTER site, station Desert study sites at Central Arizona-Phoenix Urban LTER, study of animal abundance of Lepidoptera in units of numberPerPitfallTrap 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 Central Arizona - Phoenix Urban LTER (CAP)
contains animal abundance of Lepidoptera measurements in numberPerPitfallTrap units
and were aggregated to a yearly timescale.

生态趋势（EcoTrends）项目由黛布拉·彼得斯博士（约纳达盆地长期生态研究（Long-Term Ecological Research, LTER）站，USDA-ARS约纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究（Long-Term Ecological Research, LTER）站，USDA-FS卢奎洛实验森林）于2004年设立，旨在为长期生态数据集的采集与分析工作提供支撑。本项目为一项大规模综合研究工作，致力于提升长期数据的可获取性与利用率。目前，共有约50个州立及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USDA-ARS、USDA-FS、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集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网页应用，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究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处理两种方式完成更新。该网络门户由约纳达LTER站与LTER网络办公室合作开发。以下来自亚利桑那州中部-凤凰城城市长期生态研究（Central Arizona - Phoenix Urban LTER, CAP）的数据集，包含以numberPerPitfallTrap为单位的鳞翅目（Lepidoptera）动物丰度数据，且已按年尺度完成聚合。
