Habitat loss and fragmentation intensify the effects of genetic drift and endogamy, reducing genetic variability of populations with serious consequences for wildlife conservation. The Harpy Eagle (Harpia harpyja) is a forest dwelling species that is considered near threatened and suffers from habitat loss in the forests of the Neotropical region. In this study, 72 historical and current samples were assessed using eight autosomal microsatellite markers to investigate the distribution of genetic diversity of the Harpy Eagle of the Amazonian and Atlantic forests in Brazil. The results showed that the genetic diversity of Harpy Eagle decreased in the regions where deforestation is intense in the southern Amazon and Atlantic Forest.
栖息地丧失和破碎化加剧了遗传漂变和近亲繁殖的影响，降低了种群的遗传变异性，对野生动物保护造成严重后果。角雕（Harpia harpyja）是一种栖息于森林的物种，被认为接近濒危，在新热带地区的森林中遭受栖息地丧失的困扰。在本研究中，使用八个常染色体微卫星标记对72个历史和当前样本进行了评估，以调查巴西亚马逊森林和大西洋森林中角雕的遗传多样性分布。结果表明，在亚马逊南部和大西洋森林中森林砍伐严重的地区，角雕的遗传多样性有所下降。
