生物学的一个中心目标是解释在整个生命之树中产生物种多样性模式的过程。一个可能促进生态多样化的机制是“关键创新”,即允许利用以前未开发的资源的特性。这个项目将调查一个特定的形态创新?陷阱下巴?象蚁属和齿蚁属的蚂蚁;力量增强的下颚,用于捕获猎物、防御巢穴和个体逃避捕食者。该项目将研究下颌骨的解剖和性能如何影响这些蚂蚁的多样化,以及关键创新如何影响物种多样性的模式。具体而言,该项目将:1)生成Anochetus和Odontomachus属中陷阱颚蚂蚁的物种水平分子系统发育,2)使用系统发育比较方法来研究颚形态和性能之间的关系,3)使用有限元建模来检查形态变异的功能后果。这项研究将为多功能动物运动的进化提供新的见解,整合了遗传学,形态学和工程学的数据。除了研究生培训外,拟议的研究还将直接培训综合生物学多个方面的本科生,包括高速摄像,运动分析,畜牧业和行为以及分子测序等技术。
英文摘要
A central goal of biology is to explain the processes that generate patterns of species diversity across the tree of life. One mechanism that may facilitate ecological diversification is that of "key innovations", traits that permit access to previously untapped resources. This project will investigate one particular morphological innovation in ?trap-jaw? ants in the genera Anochetus and Odontomachus: power-amplified mandibles used for prey capture, nest defense, and individual escape from predators. The project will investigate how mandible anatomy and performance has influenced the diversification of these ants, and how key innovations affect patterns of species diversity. Specifically, the project will: 1) generate a species-level molecular phylogeny for trap-jaw ants in the genera Anochetus and Odontomachus, 2) use phylogenetic comparative methods to investigate the relationship between jaw morphology and performance and 3) use finite element modeling to examine the functional consequences of morphological variation. This research will provide new insights into the evolution of multifunctional animal movements, integrating data from phylogenetics, morphology and engineering. In addition to graduate student training, the proposed research will also directly train undergraduates in multiple aspects of integrated organismal biology, including techniques such as high-speed videography, motion analysis, animal husbandry and behavior, and molecular sequencing.
