Phenology, growth, and fitness of Arabidopsis under ambient and elevated CO2 and in the presence/absence of competitors: Arabidopsis BioCON evolutionary study

We know a lot about the potential ecological effects of increasing concentrations to atmospheric CO2; however, we know relatively little about whether increased concentrations will also affect evolution. In collaboration with Jennifer Lau (KBS and Michigan State University), Peter Reich (U of MN Forestry) and Ruth Shaw (U of MN EEB) we are using a combination traditional quantitative genetic and QTL approaches to determine the effect elevated CO2 has on; patterns of selection, responses to selection, and the genetic basis of phenotypic variation.

目前学界对大气二氧化碳（CO₂）浓度升高所带来的潜在生态效应已有较为充分的认知，但对于该浓度升高是否同样会影响生物演化，我们的了解仍相对有限。我们与Jennifer Lau（基波恩生物站（KBS）与密歇根州立大学）、Peter Reich（明尼苏达大学林学院）及Ruth Shaw（明尼苏达大学进化与生态学系（EEB））合作，结合传统数量遗传学与数量性状基因座（QTL）研究方法，旨在明确大气CO₂浓度升高对以下方面的影响：选择模式、对选择的响应，以及表型变异的遗传基础。
