Abstract

Gibbons are small, arboreal apes that play a critical role in tropical biodiversity and ecosystem ecology. However, nearly all species of gibbons are threatened by habitat loss, illegal trade, hunting, and other human activities. Long-term poor understanding of their genetics and evolution undermines effective conservation efforts. In this study, we analyse comparative population genomic data of four Nomascus species. Our results reveal strong genetic differentiation among these species as well as gene flow among Nomascus species. Additionally, we identify genomic features that are potentially related to natural selection linked to vocalization, fructose metabolism, motor balance, and body size, consistent with the unique phenotype and adaptability of gibbons. Inbreeding coupled with population declines due to climate change and historical human activities leads to reduced genetic diversity and the accumulation of deleterious variation that likely affects cardiovascular disease and the reproductive potential of gibbons and further reduces their fitness, highlighting the urgent need for effective conservation strategies.

全基因组测序为长臂猿的进化适应和保护提供了见解。
长臂猿是小型的树栖类人猿,在热带生物多样性和生态系统生态学中起着至关重要的作用。然而,几乎所有种类的长臂猿都受到栖息地丧失、非法贸易、狩猎和其他人类活动的威胁。长期以来对它们的遗传和进化缺乏了解,破坏了有效的保护工作。在这项研究中,我们分析了四种野曲霉的比较种群基因组数据。我们的研究结果揭示了这些物种之间强烈的遗传分化以及Nomascus物种之间的基因流动。此外,我们确定了与自然选择有关的基因组特征,这些特征与长臂猿的独特表型和适应性相一致,这些特征与发声、果糖代谢、运动平衡和体型有关。由于气候变化和历史人类活动导致的近亲繁殖加上种群减少导致遗传多样性减少和有害变异的积累,可能影响心血管疾病和长臂猿的生殖潜力,并进一步降低其适应性,突出表明迫切需要有效的保护策略。
