历史博物馆标本揭示锯鲂遗传多样性急剧下降

研究人员利用了来自自然历史博物馆的锯鲂历史标本,其中一些可追溯到19世纪,来分析遗传多样性。这项发表在《英国皇家学会会刊B》上的研究发现,从19世纪末到21世纪初,大齿锯鲂种群的遗传多样性显著下降。分析显示,在35个历史遗传变异中,现代种群仅保留了六个,这凸显了栖息地丧失和捕捞对该物种适应能力的影响。 AI

    历史性的锯鳐收藏如何改变了保护工作

    A century's worth of sawfish rostra tucked away in museums and private collections has revealed something we couldn't see by counting animals alone: the world's largetooth sawfish have lost a remarkable amount of their genetic diversity.
