Plants are a key factor in the global climate balance, they absorb CO2 and emit oxygen, they stabilize soils and intercept rainfall, reducing erosion, they generate local microclimates and can slow the spread of deserts. However, analysis of the physical and biochemical traits of plant species in relation to climate adaptation is currently quite limited in scope. The focus of such research is generally on crops or whole ecosystems, such as grassland or forest. This PhD will study physical, biochemical and genetic features in three distantly related plant groups at the species-level to search for common patterns in relation to climate adaptation. The plant lineages under study occur predominantly in the Mediterranean climatic region but members of these lineages have spread beyond this climate zone. Common changes in features among these lineages will help understand the constraints on species imposed by climate. Your input into the project will be to test and evaluate as wide a range of characters as possible for the obvious or cryptic influence of climatic. Over the course of two years, working alongside the experts at University of Reading and the Royal Horticultural Society, the student will build up extensive datasets of features for the approximately 200 study species and these will be interpreted in the light of molecular phylogenies and climate envelope models. The applicant will have the opportunity to study preserved plants in herbaria, cultivated plants, and possibly some species in the field. You will have the opportunity to interact with internationally recognised expert groups in phylogenetics at Reading and horticultural taxonomy at the RHS Wisley. Data will be analysed using morphometric and phylogenetic approaches to interpret physical traits across phylogenies in relation to local climate adaptations.

植物是全球气候平衡的关键因素，它们吸收二氧化碳并释放氧气，稳定土壤并拦截降雨，减少侵蚀，产生当地小气候，并可以减缓沙漠的蔓延。然而，分析植物物种的物理和生物化学特性与气候适应的关系，目前在范围上相当有限。这类研究的重点通常是作物或整个生态系统，如草地或森林。该博士将研究在物种水平上三个远亲植物群体的物理，生化和遗传特征，以寻找与气候适应有关的共同模式。研究中的植物谱系主要发生在地中海气候区，但这些谱系的成员已经扩散到这个气候区之外。这些谱系特征的共同变化将有助于理解气候对物种的限制。您对该项目的投入将是测试和评估尽可能广泛的特征，以了解气候的明显或隐藏的影响。在两年的时间里，与阅读大学和皇家园艺学会的专家一起工作，学生将为大约200种研究物种建立广泛的特征数据集，并将根据分子生物学和气候包络模型进行解释。申请人将有机会研究保存在植物标本馆的植物，栽培植物，并可能在外地的一些物种。您将有机会与阅读的遗传学和RHS威斯利的园艺分类学方面的国际公认的专家组进行互动。将使用形态测量和系统发育的方法分析数据，以解释与当地气候适应有关的整个亚热带地区的物理特征。
