In the early 1800s, the European roe deer () was probably extirpated from Switzerland, due to overhunting and deforestation. After a federal law was enacted in 1875 to protect lactating females and young, and limiting the hunting season, the roe deer successfully recovered and recolonized Switzerland. In this study, we use mitochondrial DNA and nuclear DNA markers to investigate the recolonization and assess contemporary genetic structure in relation to broad topographic features, in order to understand underlying ecological processes, inform future roe deer management strategies, and explore the opportunity for development of forensic traceability tools. The results concerning the recolonization origin support natural, multidirectional immigration from neighboring countries. We further demonstrate that there is evidence of weak genetic differentiation within Switzerland among topographic regions. Finally, we conclude that the genetic data support the recognition of a single roe deer management unit within Switzerland, within which there is a potential for broad-scale geographic origin assignment using nuclear markers to support law enforcement.
在19世纪早期，由于过度捕猎和森林砍伐，欧洲狍可能已在瑞士绝迹。1875年颁布了一项联邦法律，保护哺乳期雌鹿和幼鹿，并限制狩猎季节，之后欧洲狍成功恢复并重新在瑞士定居。在本研究中，我们使用线粒体DNA和核DNA标记来调查重新定居情况，并评估与广泛地形特征相关的当代遗传结构，以便了解潜在的生态过程，为未来的狍管理策略提供信息，并探索开发法医溯源工具的机会。关于重新定居起源的结果支持来自邻国的自然、多方向移民。我们进一步证明，瑞士境内不同地形区域之间存在微弱遗传分化的证据。最后，我们得出结论，遗传数据支持在瑞士境内识别一个单一的狍管理单元，在该单元内，有可能使用核标记进行大规模地理起源归属，以支持执法工作。
