The Evo-Devo ApproachPredicting how species will fare with climate change and understanding invasive biology to aid remediation and are themes intrinsically coupled to evolutionary and developmental processes. In order to predict adaptation potential or 'evolvability' the genetic control of a trait, which is developmentally programmed, and its natural variation within and between closely related species must be understood [1,2]. By studying evolutionary and developmental biology together, and comparing results between closely related species, the evo-devo field provides rich examples of generating such understanding. Access to new methods previously constrained to 'model' systems, that the evo-devo field is now pioneering in 'non-model' groups, holds great promise for environmental research.Crepidula fornicata is invasive to the UK, it is damaging fisheries, habitats and biodiversity and is predicted to have a poleward shift in distribution, into Scottish waters, with oceanic warming. It is also a marine calcifier inhabiting coastal regions vulnerable to climatic changes such as warming and ocean acidification (OA). Recent OA experiments have shown C. fornicata are surprisingly resilient to severely acidified conditions. These findings, in combination with the history of embryological study in this species, makes it an ideal system to probe questions of resilience and adaptation to climate change.This project will take the powerful evo-devo approach and apply it to questions of major environmental significance. It will compare shell development in C. fornicata to three closely related species within the genus Crepidula to address the following questions:1.) What developmental mechanisms make C. fornicata invasive compared to its most closely related non-invasive relatives?2.) What developmental mechanisms regulate the shell traits (strength, microstructures and thickness) that give C. fornicata superior resilience to ocean acidification and climate change compared to its most closely related relatives?

EVO-DEVO的方法预测物种将如何与气候变化和理解侵入性生物学相处以帮助修复，并且主题与进化和发展过程内在结合。为了预测适应潜力或“可发展性”，必须理解经过发育编程的特征的遗传控制，并且必须理解其内部和密切相关物种之间的自然变化[1,2]。通过一起研究进化和发展生物学，并比较密切相关的物种之间的结果，Evo-Devo领域提供了丰富的产生这种理解的例子。 Access to new methods previously constrained to 'model' systems, that the evo-devo field is now pioneering in 'non-model' groups, holds great promise for environmental research.Crepidula fornicata is invasive to the UK, it is damaging fisheries, habitats and biodiversity and is predicted to have a poleward shift in distribution, into Scottish waters, with oceanic warming.它也是居住在沿海地区的海洋钙化器，容易受到气候变化的影响，例如变暖和海洋酸化（OA）。最近的OA实验表明，C. fornicata令人惊讶地抵御严重酸化的条件。这些发现与该物种中胚胎学研究的历史相结合，使其成为探测韧性和适应气候变化问题的理想系统。该项目将采用强大的EVO-DEVO方法，并将其应用于具有重大环境意义的问题。它将将c。fornicata中的壳发展与毛皮属内的三个紧密相关的物种进行比较，以解决以下问题：1。）哪些发育机制使C. fornicata具有侵入性相比，与其最紧密相关的非侵入性亲戚相比，哪些发育机制是什么？2。）哪些开发机制会使壳特质相关（强度，微型结构和厚度c. fornicience c. fornicience c. fornicience tocecation andnicience c. fornicience tonecienty andnicati andnicata c.亲戚？
