Translocation is a conservation strategy to help the plight of endangered species, and is becoming increasing important to mitigate against climate change. However translocations often fail. Theory suggests mixing individuals from different source populations would benefit species' genomic diversity and potentially success rates, however this is untested in animals. Also unclear is what parts of the genome are important for mitigating against climate change. Using an endangered lizard model, this project aims to understand how to best start new populations by 1) providing the first empirical test in terrestrial vertebrates of using mixed source populations; and 2) uncovering regions of the genome important for considering in translocations.

迁移是一种帮助濒危物种摆脱困境的保护策略，对于减缓气候变化越来越重要。然而，易位常常失败。理论表明，来自不同来源种群的个体混合将有利于物种的基因组多样性和潜在的成功率，但这尚未在动物中进行过测试。同样不清楚的是，基因组的哪些部分对减缓气候变化很重要。该项目使用濒临灭绝的蜥蜴模型，旨在了解如何通过以下方式最好地启动新种群：1）提供使用混合来源种群的陆生脊椎动物的第一个实证测试;和2）发现对于考虑易位重要的基因组区域。
