DEB 9981667FisherCalifornia Academy of SciencesThis project will enhance the understanding of the diversity and evolution of the Amblyoponini, a putative primitive lineage, and potentially a sister group of all other extant ants. Analysis of this group is critical to efforts to understand the origin and evolution of ants and their social behavior, an understanding seriously impeded by a lack of robust knowledge about themost primitive groups. In this project, the investigators will complete a species-level taxonomic revision based on comparative morphological studies of world Amblyoponini. As part of this process, morphological and molecular data will be compated to infer the phylogenetic relationships among major ant clades. The resulting phylogeny will be used to trace the evolution of important traits that are involved in colony founding, foraging behavior, communication and social structure. In addition, these phylogenies will be used to investigat eht historical biogeongraphy of these ants with respect to their prolific radiation in Madagascar.

DEB 9981667费舍尔加州科学院这个项目将提高对Amblyoponini的多样性和进化的理解，Amblyoponini是一个假定的原始谱系，可能是所有其他现存蚂蚁的姐妹群。 对这一群体的分析对于理解蚂蚁的起源和进化及其社会行为至关重要，由于缺乏对最原始群体的可靠知识，这种理解严重受阻。 在这个项目中，研究人员将完成一个物种水平的分类修订的基础上比较形态学研究的世界Amblyoponini。 作为这一过程的一部分，形态和分子数据将被比较，以推断主要蚂蚁分支之间的系统发育关系。 由此产生的遗传学将被用来追踪参与殖民地建立，觅食行为，交流和社会结构的重要特征的进化。 此外，这些基因将被用来记录这些蚂蚁在马达加斯加的多产辐射的历史。
