老挝的研究人员正在利用大象粪便的DNA追踪和保护不断下降的亚洲大象人口。 Researchers in Laos are using DNA from elephant dung to track and protect the declining Asian elephant population, which has fallen to between 500 and 1,000 from around 1,500 two decades ago. 大象面临栖息地丧失、伐木、偷猎和有限繁殖的威胁。 The elephants face threats from habitat loss, logging, poaching, and limited breeding. DNA分析有助于识别个人、跟踪流动和了解家庭关系,协助制定繁殖计划,以确保遗传多样性和物种生存。 The DNA analysis helps identify individuals, track movements, and understand family relationships, aiding in the development of breeding plans to ensure genetic diversity and species survival.
