Plant aboveground biomass data: BAC: Biodiversity and Climate (Reformatted to a Darwin Core Archive)

This data package is formatted as a Darwin Core Archive (DwC-A,
event core). For more information on Darwin Core see
https://www.tdwg.org/standards/dwc/. This Level 2 data package was
derived from the Level 1 data package found here: https://pasta.lternet.edu/package/metadata/eml/edi/124/5,
which was derived from the Level 0 data package found here:
https://pasta.lternet.edu/package/metadata/eml/knb-lter-cdr/386/8. The abstract below was extracted from the Level 0
data package and is included for context: Climate changes forecast for our region by GCM???s and shifts in biodiversity and composition each have the potential to alter ecosystem functioning; their interactive effects are unknown. The "BAC" experiment is designed to determine the direct and interactive effects of plant species numbers, plant community composition, temperature, and precipitation on 11 productivity, C and N dynamics, stability, and plant, microbe, and insect species abundances in CDR grassland ecosystems.

本数据包采用达尔文核心档案（Darwin Core Archive，缩写DwC-A，事件核心）格式。关于达尔文核心（Darwin Core）的更多信息，请参见：https://www.tdwg.org/standards/dwc/。本二级数据包源自一级数据包，其元数据链接为：https://pasta.lternet.edu/package/metadata/eml/edi/124/5；而该一级数据包又源自零级数据包，其元数据链接为：https://pasta.lternet.edu/package/metadata/eml/knb-lter-cdr/386/8。以下摘要提取自零级数据包，用于提供背景信息：全球环流模式（General Circulation Models，简称GCM）对本区域预测的气候变化，以及生物多样性与群落组成的变化，均有可能改变生态系统功能；二者的交互影响目前尚不明确。本“BAC”实验旨在探究植物物种数量、植物群落组成、温度与降水对CDR草原生态系统中11项生产力、碳（C）与氮（N）动态、系统稳定性，以及植物、微生物与昆虫物种丰度的直接及交互影响。
