358. 橙腹鹦鹉跨物种育种拯救危机
from 知为谁 · host 知为谁
这个新闻报道重点讨论了极度濒危的橙腹鹦鹉的生存困境，目前野外仅存九十多只。文章指出，该物种在不到两百年内失去了 62% 的基因多样性，使其对疾病和气候变化适应能力下降。科学家们正在考虑采取激进的保护措施，包括基因编辑或跨物种杂交，以恢复其遗传多样性。报道探究了与相关物种蓝翅鹦鹉进行杂交的可能性，将其作为对抗物种灭绝的最后手段，尽管这种方法具有争议且存在风险。这项研究强调了重建种群数量和维护遗传多样性同样重要，并引发了关于保护工作的伦理考量。内容来源：https://www.abc.net.au/news/science/2025-04-01/orange-bellied-parrots-survival-may-be-cross-species-breeding/105100274
