Abstract:
BACKGROUND: Genetics driven interventions if adopted in conservation breeding projects may enhance the overall success by prioritizing breeding among genetically most competent individuals and delaying or completely diminishing the ill effects of inbreeding.
RESULTS: In the present study, we investigated genetic make-up of 15 tigers housed at five different captive facilities of West Bengal in India and report the moderate level of genetic variation. We identified five tigers based on individual genetic attributes that may be prioritized for future breeding or animal exchange programmes. The occurrence of first and second order related individuals in captivity require management attention and they should be paired considering their immediate genetic background.
CONCLUSIONS: Considering tiger as a case study, we highlight the use of genetic assessment and necessity to validate the studbook records in formulating adaptive management strategies for long-term conservation and management of species of interest.
摘要:
背景:如果在保护性育种项目中采用遗传驱动的干预措施,则可以通过在遗传上最有能力的个体中优先进行育种并延迟或完全减少近亲繁殖的不良影响来提高整体成功。
结果:在本研究中,我们调查了在印度西孟加拉邦五个不同圈养设施中饲养的15只老虎的遗传组成,并报告了中等水平的遗传变异。我们根据个体遗传属性确定了五只老虎,这些老虎可能会优先用于未来的育种或动物交换计划。被囚禁的一阶和二阶相关个体的发生需要管理方面的关注,并且应该考虑到他们的直接遗传背景进行配对。
结论:以老虎为例,我们强调使用遗传评估和必要性来验证研究簿记录,以制定适应性管理策略,以长期保护和管理感兴趣的物种。
