Ant responses to experimental warming and plant diversity:BAC: Biodiversity and Climate

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.基于全球环流模式（Global Circulation Models, GCMs）预测的本区域气候变化，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未明确。"BAC"实验旨在探明植物物种数量、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、碳氮动态、稳定性以及植物、微生物与昆虫物种多度的直接效应与交互效应。
