中国区域管鼻蝠亚科（Murininae）性二型驱动机制的研究

性二型是生物界中一种普遍的生态现象，其驱动机制也是进化生物学中历久不衰的课题之一。哺乳动物常显示出偏雄的性二型特征，但在翼手目（即蝙蝠）中常显示出相反的模式，即雌性大于雄性。管鼻蝠亚科Murininae（隶属翼手目蝙蝠科）包含管鼻蝠属Murina和毛翼管鼻蝠属Harpicephulus两个属，均为森林性蝙蝠，虽然该类群中性二型现象广泛存在，但尚未有对其驱动机制的系统研究。经近十年对该类群的持续性关注及一定数量的标本和数字资源的积累，本课题以该类群为研究对象，通过整合三维（3D）扫描重建、稳定同位素分析技术、传统形态学、几何形态学、亲缘地理学、系统发育学与系统发育比较学等方法，对中国区域的该类群物种进行性二型的特征分析，探讨其性二型潜在的进化驱动因素，并整合该数据与证据运用系统发育比较学与广义线性建模等方法，在宏进化尺度探讨该类群性二型的驱动机制，推动我国的蝙蝠研究达到国际先进水平。

Sexual dimorphism in mammals is a common phenomenon that has provoked intense interest. Most mammals reveal a male-biased sexual dimorphism, namely male is larger than female, while a reversed pattern (female-biased sexual dimorphism) is emerged in Chiroptera. Murininae that consisting of Harpiocephalus and Murina, is typical forest bat group with distinct sexual dimorphism. The underlying mechanism, neverthelss, is still unknown. Based upon the well accumulation of considerable specimens and biological data on this group through up to 10 years’ efforts from our lab, a research project focusing on mechanisms of sexual dimorphism of Murininae from China was proposed. Through the integrations of data and evidences from different disciplines and analysis technics including three-dimensional (3D) scanning technology, traditional numerical taxonomy, morphology, geometric morphology, stable isotope analysis technology, phylogenetic and biogeographic methods, we aim to 1) quantify the sexual dimorphism characteristics of each species that distributed in China and explore the potential historical driving factors individually; 2) according to evidence and data mentioned above untangle mechanisms of sexual dimorphism within Murininae using phylo-comparative analyses and general linear modeling, which promoting the researches on bat in China to international advanced level.
