Mammalian biodiversity is often linked to dietary diversity, with species possessing masticatoryspecialisations to help them attain and consume different foods. Whilst adult phenotypes have receivedmuch attention in relation to dietary adaptations, habitat and species ranges, much less work has beendone on juveniles. During development bone grows and adapts, teeth wear and are replaced, and muscleproperties change, but their impact (in isolation and combination) on feeding performance has rarelybeen studied, limiting our understanding of the impact of dietary shifts due to environment change.This project will apply traditional dissection and virtual anatomy techniques (DiceCT, imagesegmentation, muscle dissection) to quantify how the hard and soft tissue anatomy of species,belonging to different dietary categories, changes during development. Using physical testing (universalmaterials testing, 3D printing technologies) and biomechanical modelling (multibody dynamicmodelling), the impact of these changes on performance will be assessed.

哺乳动物的生物多样性往往与饮食多样性有关，因为某些物种具有咀嚼专门化，以帮助它们获得和消耗不同的食物。虽然成年表型在饮食适应、栖息地和物种范围方面受到了很多关注，但对青少年的研究却少得多。在发育过程中，骨骼生长和适应，牙齿磨损和更换，肌肉特性发生变化，但它们的影响（单独和组合）对摄食性能的影响很少被研究，限制了我们对环境变化引起的饮食变化影响的理解。本项目将应用传统解剖和虚拟解剖技术（DiceCT，imagesegmentation，muscle dissection）来量化属于不同饮食类别的物种的硬组织和软组织解剖结构在发育过程中的变化。使用物理测试（通用材料测试，3D打印技术）和生物力学建模（多体动态建模），将评估这些变化对性能的影响。
