A pilot field study was conducted in Sulawesi (Indonesia) to assess the status of macaque populations on the island. Wild and captive animals were sampled, mainly in border areas between presumed different species. The five species investigated were Macaca maurus, M. tonkeana, M. hecki, M. nigrescens, and M. nigra, for which morphological and gene frequency data suggested the presence of hybridization zones. Some individuals within these zones showed intermediate or mosaic morphology between parental forms. These individuals also had intermediate gene frequencies for most of the polymorphic systems investigated. Karyotypes were identical in all species, and no cytogenetic barrier to hybridization existed between species. A review of the recent literature also provided evidence for hybridization between Sulawesi macaques. Clinical frequencies in both morphological and biomolecular traits perhaps can be best explained by the operation of gene flow between the various forms of macaques on the island. However, additional data are necessary before current classification schemes are revised. The unique opportunity and need of further study of Sulawesi macaques for a range of evolutionary questions is emphasized.
在印度尼西亚苏拉威西岛进行了一项试点实地研究，以评估该岛猕猴种群的状况。对野生和圈养动物进行了采样，主要在假定的不同物种之间的边境地区。所调查的五个物种是黑冠猕猴、汤基猕猴、黑克猕猴、黑须猕猴和黑猕猴，形态学和基因频率数据表明存在杂交区域。这些区域内的一些个体在亲本形态之间表现出中间或镶嵌形态。这些个体在大多数所研究的多态系统中也具有中间基因频率。所有物种的核型相同，物种之间不存在杂交的细胞遗传学障碍。对近期文献的综述也为苏拉威西猕猴之间的杂交提供了证据。形态和生物分子特征方面的临床频率或许可以通过该岛各种猕猴形态之间的基因流动来最好地解释。然而，在修订当前分类方案之前还需要更多数据。强调了对苏拉威西猕猴进行一系列进化问题进一步研究具有独特机会和必要性。
