Lemur fulvus, L. catta, and L. variegatus differ markedly in the details of mother-infant relations. Do these differences account for those seen in adult life? We hope to determine this through interspecific cross-fostering. Here we describe the normal pattern of rearing of 5 infants among two groups of 2 and 5 adult L. variegatus, reared in the laboratory. The descriptions cover the first 7 months of life, and include the effects of maternal separation at 150 days of age, when estrus normally disrupts maternal care. The principal finding is that in the mother's absence young turn more to other adults than to their siblings, who are, apparently, not adequate social substitutes for adults.
环尾狐猴、褐美狐猴和白眉美狐猴在母婴关系细节上有显著差异。这些差异能解释成年后的差异吗？我们希望通过种间交叉寄养来确定这一点。在此，我们描述了在实验室饲养的两组成年环尾狐猴（一组2只，另一组5只）中5只幼崽的正常饲养模式。这些描述涵盖了生命的前7个月，包括150日龄时母婴分离的影响，此时发情期通常会干扰母性照料。主要发现是，在母亲不在时，幼崽更多地转向其他成年个体而非其兄弟姐妹，显然，兄弟姐妹并不能充分替代成年个体成为社交对象。
