野生动物犯罪继续对动植物种群及其环境构成巨大威胁。在努力制止当前生物多样性危机的不同学科中,野生动物法医学已成为打击野生动物犯罪的工具,将DNA法医学方法应用于收集证据和调查情报变得越来越重要。野生动物DNA法医实验室提供的广泛服务要求开发诊断性遗传标记和健全的分子遗传学协议,以确保收集的任何证据都能经得起法庭的审查。适当担保的参考样本对于生成可靠的野生动物法医DNA数据至关重要;然而,获取这些稀有、濒危物种或居住在偏远地区的物种的参考样本可能具有挑战性。在此,我们强调以保护和研究为重点的生物库作为获取野生动物DNA法医足够参考样本的来源的重要性。此外,我们鼓励野生动物法医遗传学家与以保护和研究为重点的生物库开展合作,并在野生动物法医界之间共享数字DNA,以此作为克服样本和DNA数据采集相关挑战的战略,从而加快打击野生动物犯罪的执法成功实施。
Wildlife crime continues to pose a great threat to animal and plant populations and their environments. Among the different disciplines striving to halt the current biodiversity crisis, wildlife forensics has become instrumental in combating wildlife crime, with the application of DNA forensics methods to the gathering of evidence and intelligence for investigations gaining increasing importance. The wide range of services offered by wildlife DNA forensics laboratories requires the development of diagnostic genetic markers and robust molecular genetics protocols to ensure that any evidence gathered can withstand scrutiny in court. Appropriately vouchered reference samples are crucial for the generation of robust wildlife forensics DNA data; however, access to these reference samples for rare, endangered species, or those inhabiting remote areas, can be challenging. Here, we highlight the importance of conservation and research-focused biobanks as a source to obtain adequate reference samples for wildlife DNA forensics. Furthermore, we encourage collaboration between wildlife forensic geneticists and conservation and research-focused biobanks, as well as the sharing of digital DNA among the wildlife forensics community, as strategies to overcome the challenges associated with sample and DNA data acquisition and hence accelerate the successful implementation of law enforcement for combating wildlife crime.
