Increased phenotypic variation via evolutionarily novel stressors

该项目旨在了解进化上新的应激源（如致肥性饮食）如何诱导生物体性状的表型变异。这种增加的表型变异传统上被认为是遗传的。然而，越来越多的证据表明，非遗传机制能够跨代遗传。该项目将使用互补的方法来研究新的压力源如何产生表型变异。该项目旨在提供一个更综合的进化视角，不仅研究表型进化和变异维持，还研究肥胖的跨代成本。

This project aims to understand how evolutionarily novel stressors such as obesogenic diets induce phenotypic variation in organismal traits. Such increased phenotypic variation is traditionally thought to be genetic. However, growing evidence points to non-genetic mechanisms that are capable of transgenerational inheritance. The project will use complementary approaches to study how novel stressors generate phenotypic variation. The project aims to deliver a more integrated evolutionary perspective not only on phenotypic evolution and the maintenance of variation, but also on the transgenerational cost of obesity.
