Historic museum specimens reveal drastic decline in sawfish genetic diversity

By PulseAugur Editorial · [1 sources] ·

Researchers have utilized historic sawfish specimens from natural history museums, some dating back to the 1800s, to analyze genetic diversity. This study, published in Proceedings of the Royal Society B, found a significant decline in genetic diversity within largetooth sawfish populations from the late nineteenth century to the early twenty-first century. The analysis revealed that out of 35 historical genetic variants, only six remain in modern populations, highlighting the impact of habitat loss and fishing on the species' adaptability. AI

    How Historic Sawfish Collections Changed Conservation

    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.
