This project aims to better understand the phenotypic variations and underlying genetics of how members of the Bathyergidae family are adapted to their specific local environmental niches. By studying the 5 species within the genus Cryptomys, and populations of the same species within different parts of their ranges, we can investigate what species/population-level physiological and morphological adaptations exist compared to the variety of macro- and micro-level environments that this group inhabit. By investigating ecological differences such as rainfall, altitude, food availability, temperature and soil composition over their respective ranges, we will compare the physiological and morphological adaptations of species and different populations to their local environment, and whether this is found at the genetic level, to understand the evolutionary patterns that persist. This will be carried out through field work in South Africa on both captive and wild animals, and through the use of museum specimens, to look at metabolic rates, responses to temperature changes, morphometrics (on live animals, extant museum specimens as well as potentially fossil data), and genetic and genomic analyses of haemoglobin genes and heat shock protein genes, and genome wide SNPs.

该项目旨在更好地了解 Bathyergidae 家族成员如何适应其特​​定的当地环境生态位的表型变异和潜在遗传学。通过研究隐鼠属内的 5 个物种，以及同一物种在其分布范围内不同部分的种群，我们可以研究与该群体栖息的各种宏观和微观环境相比，存在哪些物种/种群水平的生理和形态适应。通过调查各自范围内的降雨量、海拔、食物供应、温度和土壤成分等生态差异，我们将比较物种和不同种群对其当地环境的生理和形态适应，以及这是否在遗传水平上发现，以了解持续存在的进化模式。这将通过在南非对圈养和野生动物进行实地工作，并通过使用博物馆标本来研究代谢率、对温度变化的反应、形态测量（活体动物、现存博物馆标本以及潜在的化石数据），以及血红蛋白基因和热休克蛋白基因以及全基因组单核苷酸多态性的遗传和基因组分析。
