It is commonly argued that genetic diversity is important for the conservation of a threatened species. Unfortunately, for most threatened species we know little about how genetic variation in ecologically relevant traits (e.g. drought tolerance) may contribute to the survival of a species. This kind of information is especially important because they provide habitat for many other organisms. Blue oak (Quercus douglasii), a threatened keystone species in California, is currently not regenerating throughout much of its geographic range. Blue oak woodlands are one of the most biologically diverse ecosystems on the planet, second only to tropical forests. As such, a loss of this species and thus the habitat it creates would result in a major reduction of biodiversity. This study will focus on a series of field experiments designed to examine how genetic variation in morphology and drought tolerance affects survival and growth in blue oak seedlings and adults. We hope to be able to identify drought resistant and competitive oak genotypes that may be important sources of germplasm for current and future efforts to restore and maintain this critically important species.//

人们普遍认为遗传多样性是重要的 为 保护濒危物种。 不幸的是，对于 最 受威胁的物种，我们对遗传变异是如何在 生态相关性状（例如耐旱性）可 对一个物种的生存有贡献。 这种 信息 尤其重要，因为它们为许多 其他 有机体 蓝栎（Quercus douglasii），一个受威胁的关键物种， 加州，目前在其大部分地区都没有再生 地理范围。 蓝橡树林地是世界上 地球上生物多样性生态系统，仅次于 热带森林 因此，这一物种的损失， 它创造的栖息地将导致 生物多样性 本研究将集中在一系列领域 旨在研究基因变异如何在 形态 耐旱性影响蓝橡的存活和生长 幼苗和成虫。 我们希望能够识别干旱 抗性和竞争性的橡木基因型可能是重要的 目前和今后努力恢复的种质资源 和 这是一个非常重要的物种。
