马达加斯加狐猴是世界上最小的灵长类动物之一。几个兄弟物种是已知的。其中，棕狐猴和灰鼠狐猴在形态、遗传和交流方面有所不同。它们也可能在季节性繁殖和体重变化方面有所不同。在相同的光周期条件下，研究比较了两种成功繁殖种群的雄性和雌性的生殖活动和月体重变化。这两个物种的雌性只在长白天出现发情周期。雌性红鼠狐猴的妊娠期似乎比它们的兄弟物种短（57天对62天）。发情周期数（2.25 vs 2.5/季）和发情周期长度（59 vs 52天）相似。产仔数(2)似乎相似。光周期刺激后的发情潜伏期（71.6天和42.3天）比兄弟种长。对于睾丸生长的开始也是如此。在两个物种中，睾丸的生长速度和大小是相似的，并且在发情开始之前。红狐猴的生殖活动在两性中都比灰鼠狐猴短。在这两个物种中，体重表现出相似的季节性变化。雄性在繁殖季节比雌性减重更多。在棕鼠狐猴中，在非繁殖季节，两性的体重相似。在灰鼠狐猴中，性别在一年中有所不同。
The nocturnal Malagasy mouse lemurs are among the smallest primates worldwide. Several sibling species are known. Of these, the rufous and the gray mouse lemur differ with respect to morphology, genetics, and communication. They might also differ in seasonal reproduction and body weight changes. We investigated and compared reproductive activities and changes in monthly body weight in males and females of successfully breeding colonies of both species under the same photoperiodic conditions. Females of both species showed estrous cycles only during the long-day period. Rufous mouse lemur females seemed to have a shorter gestation than their sibling species (57 vs. 62 days). The number of estrous cycles (2.25 vs. 2.5/season) and their lengths (59 vs. 52 days) were similar. Litter size (2) seemed to be similar. Latency of estrous occurrence after photoperiodic stimulation was longer in Microcebus rufus than in its sibling species (71.6 and 42.3 days). The same was true for the onset of the growth of the testes. The rate of growth and size of the testes were similar, and precede the estrous onset in both species. The reproductive activity was shorter in both sexes of the rufous than of the gray mouse lemurs. In both species, body weight showed similar seasonal changes. Males lost more weight during the breeding season than females did. In rufous mouse lemurs, body weight was similar in both sexes during the nonbreeding season. In gray mouse lemurs, sexes differed throughout the year.
