AbstractDEB-0129299M. Denise DearingWorkshop: Proposal for Conference on the History of Atmospheric CO2 and its Effect on the Evolution of Plants, Animals, and EcosystemsSeveral new proxies to estimate the concentration of atmospheric CO2 have been developed in the last few years so that our understanding of the history of CO2 in the atmosphere is much improved. Plant growth is strongly influenced by the concentration of atmospheric CO2, causing changes in nutrient status and the production of plant toxins, and affecting the competition between plants using different photosynthetic pathways or having different physiological strategies. Changes in availability, nutrient content, or toxicity of certain plants impacts animals at the ecosystem level. Therefore, atmospheric CO2 can be considered to be a driver of evolution at the ecosystem level. The time is now ripe for a synthesis of recent work that links the history of atmospheric CO2 to evolution at the ecosystem level. This grant will support an international symposium to address this topic.

摘要DEB-0129299 M。Denise DearingWorkshop：建议召开关于大气CO2历史及其对植物、动物和生态系统进化的影响的会议在过去几年中，已经开发了几种新的估算大气CO2浓度的替代物，从而大大提高了我们对大气中CO2历史的理解。植物生长受到大气CO2浓度的强烈影响，引起营养状况的变化和植物毒素的产生，并影响使用不同光合途径或具有不同生理策略的植物之间的竞争。某些植物的可用性、营养成分或毒性的变化在生态系统层面上影响动物。因此，大气中的二氧化碳可以被认为是生态系统一级进化的驱动力。现在时机已经成熟，可以综合最近的工作，将大气CO2的历史与生态系统层面的演变联系起来。这笔赠款将支持一个国际研讨会，以解决这个问题。
