摘要本文利用对两种近亲松鼠猴（sammiri oerstedi和S. sciureus）的生态学和行为学数据，对群居灵长类动物雌性结合变异的假说进行了检验。生活在紧密群体中的物种的社会关系被认为取决于资源竞争的性质。S. oerstedi和S. sciureus都生活在大群体中，受到强烈的捕食。群体间和群体内的直接摄食竞争极低；在这个物种中，雌性关系没有分化，没有明显的雌性统治等级，雌性从它们的出生群体中分散开来。群间竞争也很低，但群内对资源的直接竞争很频繁；这个物种表现出不同的雌性关系，雌性统治等级和雌性哲学。在这两个同系物中发现的相关生态和社会变量进一步减少了系统发育差异的次要影响，并强调了食物分布在决定社会特征中的重要性。
SummaryEcological and behavioral data from long-term field studies of known individuals in two closely related squirrel monkey species (Saimiri oerstedi and S. sciureus) were used to examine hypotheses about the source of variation in female bonding among group-living primates. Social relationships in species which live in cohesive groups are thought to depend on the nature of competition for resources. S. oerstedi and S. sciureus both live in large groups and are subject to intense predation. Direct feeding competition both between and within groups is extremely low in S. oerstedi; in this species female relationships are undifferentiated, no female dominance hierarchy is evident and females disperse from their natal group. S. sciureus also experiences very low levels of between-group competition, but within-group direct competition for resources is frequent; this species demonstrates differentiated female relationships, a female dominance hierarchy, and female philopatry. The correlated ecological and social variables found in these two congeners further minimize the minor effects of phylogenetic differences and emphasize the importance of food distribution in determining social characteristics.
