人类活动破坏大象的息地, 导致非洲各地的大象孤立和同胞繁殖. Human activity fragments elephant habitats, causing isolation and inbreeding across Africa.

非洲大象的基因组研究显示, 人类活动使得息地分散,导致孤立和近亲繁殖. A genomic study of 232 African elephant genomes reveals that human activities have fragmented habitats, causing isolation and inbreeding. 非洲东北部的象群表现出高水平的近亲生和有害突变,而孤立的西非大象由于杂交保留了一些变异. Populations in northeast Africa show high inbreeding and harmful mutations, while isolated West African elephants retain some variation due to hybridization. 研究人员警告说, 没有连接, 即使是受保护的群体也会面临遗传衰退的风险, 这凸显了需要息地走廊和国际合作. Researchers warn that without connectivity, even protected herds risk genetic decline, highlighting the need for habitat corridors and international cooperation.
