Primate vocalizations convey a variety of information to conspecifics. The acoustic traits of these vocalizations are an effective vocal fingerprint to discriminate between sibling species for taxonomic diagnosis. However, the vocal behavior of nocturnal primates has been poorly studied and there are few studies of their vocal repertoires. We compiled a vocal repertoire for the Endangered Sambirano mouse lemur, Microcebus sambiranensis, an unstudied nocturnal primate of northwestern Madagascar, and compared the acoustic properties of one of their call types to those of M. murinus and M. rufus. We recorded vocalizations from radio-collared individuals using handheld recorders over 3 months. We also conducted an acoustic survey to measure the vocal activity of M. sambiranensis in four forest habitat types at the study site. We identified and classified five vocalization types in M. sambiranensis. The vocal repertoires of the three Microcebus species contain very similar call types but have different acoustic properties, with one loud call type, the whistle, having significantly different acoustic properties between species. Our acoustic survey detected more calls of M. sambiranensis in secondary forest, riparian forest, and forest edge habitats, suggesting that individuals may prefer these habitat types over primary forest. Our results suggest interspecific differences in the vocal repertoire of mouse lemurs, and that these differences can be used to investigate habitat preference via acoustic surveys.

在栖息地偏好的声学调查中使用 Sambirano Mouse Lemur (Microcebus sambiranensis) 的发声

灵长类动物的发声向同种动物传达各种信息。这些发声的声学特征是区分同胞物种进行分类诊断的有效声音指纹。然而,对夜间灵长类动物的发声行为研究甚少,对其发声曲目的研究也很少。我们为濒临灭绝的 Sambirano 鼠狐猴 Microcebus sambiranensis(一种未研究的马达加斯加西北部的夜间灵长类动物)编写了一个声音曲目,并将它们的一种呼叫类型与 M. murinus 和 M. rufus 的声学特性进行了比较。我们使用手持录音机记录了 3 个月内佩戴无线电项圈的人的声音。我们还进行了声学调查,以测量研究地点四种森林栖息地类型中 M. sambiranensis 的声音活动。我们在 M. sambiranensis 中识别并分类了五种发声类型。三种 Microcebus 物种的声音曲目包含非常相似的叫声类型,但具有不同的声学特性,其中一种响亮的叫声类型,口哨,在物种之间具有显着不同的声学特性。我们的声学调查在次生林、河岸林和林缘生境中检测到更多的 M. sambiranensis,这表明与原始森林相比,个体可能更喜欢这些生境类型。我们的研究结果表明,小鼠狐猴的声音曲目存在种间差异,这些差异可用于通过声学调查研究栖息地偏好。三种 Microcebus 物种的声音曲目包含非常相似的叫声类型,但具有不同的声学特性,其中一种响亮的叫声类型,口哨,在物种之间具有显着不同的声学特性。我们的声学调查在次生林、河岸林和林缘栖息地中检测到更多的 M. sambiranensis,这表明与原始森林相比,个体可能更喜欢这些栖息地类型。我们的研究结果表明,小鼠狐猴的声音曲目存在种间差异,这些差异可用于通过声学调查研究栖息地偏好。三种 Microcebus 物种的声音曲目包含非常相似的叫声类型,但具有不同的声学特性,其中一种响亮的叫声类型,口哨,在物种之间具有显着不同的声学特性。我们的声学调查在次生林、河岸林和林缘栖息地中检测到更多的 M. sambiranensis,这表明与原始森林相比,个体可能更喜欢这些栖息地类型。我们的研究结果表明,小鼠狐猴的声音曲目存在种间差异,这些差异可用于通过声学调查研究栖息地偏好。表明个人可能更喜欢这些栖息地类型而不是原始森林。我们的研究结果表明,小鼠狐猴的声音曲目存在种间差异,这些差异可用于通过声学调查研究栖息地偏好。表明个人可能更喜欢这些栖息地类型而不是原始森林。我们的研究结果表明,小鼠狐猴的声音曲目存在种间差异,这些差异可用于通过声学调查研究栖息地偏好。
