Proposal for Conference on the History of Atmospheric CO2 and its Effect on the Evolution of Plants, Animals, and Ecosystems (Workshop held in Snowbird, Utah on December 6-8, 2001)

abstractdeb - 0129299 m。丹尼斯·迪林研讨会：“大气二氧化碳的历史及其对植物、动物和生态系统进化的影响”会议提案在过去几年中，已经开发了几种新的估算大气二氧化碳浓度的代用物，从而大大提高了我们对大气中二氧化碳历史的了解。植物的生长受到大气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，并影响不同光合途径或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水平上影响动物。因此，大气中的二氧化碳可以被认为是生态系统水平进化的驱动力。将大气二氧化碳的历史与生态系统水平的进化联系起来的最新工作，现在时机成熟了。这项奖助金将支持一个国际专题讨论会来讨论这个题目。

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.
