This project aims to understand the processes that limit adaptation to rapid environmental change. Adaption to rapid environmental change determines population persistence. Species with restricted distributions may lack the genetic variation necessary to adapt to changing environments, although they represent the vast majority of biodiversity. Understanding why they lack the necessary genetic variation for adaptation is important for identifying and managing vulnerable biological systems. This project will empirically determine the contribution of mutations to key traits to better understand what limits evolutionary adaptation. Better prediction of extinction risk should inform conservation and biodiversity management.

该项目旨在了解限制适应快速环境变化的过程。对快速环境变化的适应决定了种群的持久性。分布受限的物种可能缺乏适应不断变化的环境所需的遗传变异，尽管它们代表了绝大多数生物多样性。了解它们为什么缺乏适应所需的遗传变异，对于识别和管理脆弱的生物系统非常重要。该项目将从经验上确定突变对关键性状的贡献，以更好地了解是什么限制了进化适应。对灭绝风险的更好预测应该为保护和生物多样性管理提供信息。
