Biodiversity of the brown lemur complex:Taxonomy and phylogeography of Eulemur fulvus ssp.

本研究的目的是阐明“黄尾鳗复合体”的多样性和进化史。这组马达加斯加灵长类动物传统上被认为由6-8个不严格的异域亚种组成。然而，最新的分类修订将它们提升到完整的物种等级，但没有提供令人信服的证据。为了明确它们的分类地位和系统发育关系，我们希望收集和分析四种新数据。在40个地点，我们将收集粪便样本，提取线粒体和核DNA，用于后续测序。这些遗传数据将用于量化种群间的遗传交换，并建立这种交换的时间框架。同样的动物也将被拍照，以量化不同种群之间皮毛颜色的假设变化。通过对先天发声的记录和分析，将对种群的行为差异进行举例研究。最后，我们将从具有可靠位置的博物馆标本中获得形态测量数据，以研究分类群之间的形态差异。通过对不同数据集的整合，建立可靠的褐狐猴分类体系，重建褐狐猴的系统生物地理学，为褐狐猴的保护建议提供依据。

The aim of this study is to clarify the diversity and evolutionary history of the “Eulemur fulvus complex”. This group of Malagasy primates was traditionally considered to consist of 6-8 not strictly allopatric subspecies. The latest taxonomic revision elevated them to full species rank, without providing convincing evidence, however. To clarify their taxonomic status and phylogenetic relationships, we want to collect and analyze four types of new data. At 40 field sites, we will collect fecal samples to extract mitochondrial and nuclear DNA for subsequent sequencing. These genetic data will be used to quantify the genetic exchange among populations and to establish a temporal framework of this exchange. The same animals will also be photographed to quantify postulated variation in fur coloration among populations. Population differentiation in behavior will be studied exemplarily by recording and analyzing an innate vocalization. Finally, we will obtain morphometric data from museum specimens with reliable localities to examine morphological variation among taxa. By combining different data sets, we hope create a reliable taxonomy of brown lemurs, to reconstruct their phylobiogeography, and to provide a basis for conservation recommendations.
