性广告呼吁雄性鼠狐猴从两个相邻的德梅斯在干燥的落叶林马达加斯加西部的繁殖季节期间记录。Demes相距约1.5公里，彼此之间没有地理障碍。他们的特点是形态和基因型的RAPD指纹。根据单变量和多变量统计分析，demes不同的身体测量，也没有在RAPD指纹图谱产生的带型。广告呼叫的声学模式，然而，表现出显着差异：六个变量的频率和时间域之间的不同。判别函数分析表明，一个变量，总通话时间，是足够的分类超过89%的电话正确的相应的德美。我们假设这些差异与鸟类的方言相似，因为在形态上和遗传上都无法区分，并且没有障碍阻止它们之间的遗传交流。可能的解释出现的方言在一个原猿类物种的概述。
Sexual advertisement calls of male mouse lemurs from two neighbouring demes in a dry deciduous forest of western Madagascar were recorded during the breeding season. Demes were located about 1.5 km apart with no geographic barrier between them. They were characterised morphometrically and genotyped by RAPD fingerprinting. According to univariate and multivariate statistical analysis, demes differed neither in body measurements, nor in the banding patterns produced by RAPD fingerprinting. The acoustic pattern of the advertisement call, however, showed significant differences: Six variables of the frequency and time domain differed between the demes. Discriminant function analysis revealed that one variable, total call duration, was sufficient to classify more than 89% of the calls correctly to the corresponding deme. We postulate that these differences are comparable to dialects in birds, because demes were morphologically and genetically indistinguishable and no barrier prevented genetic exchange between them. Possible explanations for the emergence of dialects in a prosimian species are outlined.
