科学家测试冷冻蝴蝶蛋 以拯救濒临灭绝的英国燕尾鱼 Scientists test freezing butterfly eggs to save the endangered British Swallowtail.

Anglia Ruskin大学的研究人员在196°C对液氮中冷冻的冷冻保护蝴蝶蛋进行测试,以帮助保护稀有的英国燕尾鱼,由于生境丧失、气候变化和遗传多样性低,这种稀有的英国燕尾鱼在过去20年中减少了57%。 Researchers at Anglia Ruskin University are testing cryopreservation—freezing butterfly eggs in liquid nitrogen at -196°C—to help conserve the rare British Swallowtail, which has declined by 57% over the past two decades due to habitat loss, climate change, and low genetic diversity. 科学家在Jimmy农场和野生动物公园使用一个密切相关、更丰富的物种产卵, 目的是确定冷冻鸡蛋能否发展成健康的、生殖性的蝴蝶。 Using eggs from a closely related, more abundant species at Jimmy’s Farm and Wildlife Park, scientists aim to determine if frozen eggs can develop into healthy, reproductive butterflies. 如果成功,该方法能够长期储存遗传材料,供将来的育种和重新引进工作使用。 If successful, the method could enable long-term storage of genetic material for future breeding and reintroduction efforts. 该项目在英国生物银行自然保护协会的支持下,被认为是首个此类蝴蝶项目,可以使其他授粉者和无脊椎动物受益,支持更广泛的养护和生态系统健康。 The project, supported by UK biobank Nature’s SAFE, is believed to be the first of its kind for butterflies and could benefit other pollinators and invertebrates, supporting broader conservation and ecosystem health.
