Ongoing global climate change is placing selection pressures on populations world-wide. For many populations, traits will evolve in ways that promote survival and reproduction under the altered ecological conditions that climate change will bring. This workshop will provide the initial planning for Project Baseline, a nation-wide collaborative effort to gather, freeze and archive seed from contemporary plant populations. Decades from now, these ancestral seeds can be "resurrected" and grown side by side with their descendants under controlled environmental conditions. Evolutionary changes in ecologically important traits then can be measured and the genetic basis for these changes probed. The proposed workshop will gather ideas from top researchers in plant population biology, genomics, and theoretical evolutionary genetics for the design of seed collection protocols and will compile a list of candidate plant species. Plant seed conservation experts will provide advice on the logistics of cataloging and preserving seeds for future use. Future biologists will be able to use these resources to answer significant questions concerning the genetic basis of evolutionary change by studying both adaptive responses to selection and limits to adaptation.

持续的全球气候变化正在给世界范围内的种群带来选择压力。对于许多种群来说，在气候变化将带来的生态条件改变下，性状将以促进生存和繁殖的方式进化。本次研讨会将为基线项目提供初步规划，这是一个全国性的合作项目，旨在收集、冷冻和存档当代植物种群的种子。几十年后，这些祖先的种子可以“复活”，并在受控的环境条件下与后代并肩生长。这样就可以测量重要生态性状的进化变化，并探索这些变化的遗传基础。该研讨会将收集来自植物种群生物学、基因组学和理论进化遗传学领域的顶尖研究人员的想法，以设计种子收集方案，并将编制候选植物物种清单。植物种子保护专家将就种子编目和保存的后勤工作提供建议，以备将来使用。未来的生物学家将能够利用这些资源，通过研究对选择的适应性反应和适应的限制，来回答有关进化变化的遗传基础的重要问题。
