This study will examine processes that lead to the diversification of species -- in number, form and ecology. First, a phylogeny of the Madagascar pseudoxyrhophiine snakes will be produced. This highly diverse group of vertebrates, with more than 130 species, occurs in arboreal, terrestrial, fossorial, and aquatic habitats, as well as tropical rainforests, mountain forests, swamps, grasslands and deserts. Using Next Generation Sequencing (NGS) techniques to generate hundreds of genes, the first comprehensive phylogeny of this snake group will be produced. Second, the phylogeny will be integrated with morphological and ecological data (including remotely-sensed data and GIS), in a computationally intense framework, to reveal how species, ecology and morphology evolve together over time and to examine the processes associated with adaptive radiations. This project will also train undergraduates, doctoral students, and a postdoctoral researcher. Results will be widely communicated to the public via the American Museum of Natural History's Science Bulletin, CUNY's TV Program "Study with the Best", and other formats. In addition to revealing complex evolutionary processes, results of this research will also have valuable conservation applications for this group of snakes.

这项研究将研究导致物种在数量、形态和生态方面多样化的过程。首先，将产生马达加斯加拟氧蛇蛇的系统发育。这个高度多样化的脊椎动物群有 130 多个物种，分布在树栖、陆地、化石和水生生境以及热带雨林、山地森林、沼泽、草原和沙漠中。使用下一代测序（NGS）技术生成数百个基因，将产生该蛇类的第一个全面系统发育。其次，系统发育将在计算密集型框架中与形态和生态数据（包括遥感数据和地理信息系统）相结合，以揭示物种、生态和形态如何随着时间的推移一起进化，并检查与适应性辐射相关的过程。该项目还将培养本科生、博士生和博士后研究员。结果将通过美国自然历史博物馆的科学公报、纽约市立大学的电视节目“与最好的人一起学习”和其他形式向公众广泛传播。除了揭示复杂的进化过程之外，这项研究的结果还将对这群蛇的保护具有有价值的应用。
