The Evolutionary Consequences of Interspecific Aggression

物种之间的侵略是非常常见的，当它导致性状的分歧，可以促进生物多样性。该项目汇集了来自美国和墨西哥的理论家和生物学家，以研究种间侵略在进化多样化中的作用。该项目将开发和测试理论，以预测Hetaerina豆娘物种之间领土侵略的进化后果。这些色彩鲜艳的昆虫提供了一个易于处理的模型，在这个模型中，种间攻击的影响可以与其他过程产生的影响区分开来。该项目将使用实地实验来告知和完善豆娘中攻击性相互作用的详细模型，并将针对行为和颜色的地理变化模式以及物种分歧的分子测量来测试该模型。该项目将统一以前的工作物种之间的相互作用及其在创造生物多样性的作用，并将开发一个正式的模型框架，以指导未来的研究种间侵略的进化后果。该项目将为本科生和研究生提供跨学科培训，并包括强有力的国际合作。

Aggression between species is extremely common and, when it causes divergence of traits, can contribute to biodiversity. This project brings together theorists and empiricists from the United States and Mexico to investigate the role of interspecific aggression in evolutionary diversification. The project will develop and test theory to predict the evolutionary consequences of territorial aggression between species of Hetaerina damselflies. These brightly colored insects provide a tractable model in which the effects of interspecific aggression can be distinguished from those resulting from other processes. The project will use field experiments to inform and refine a detailed model of the workings of aggressive interactions in damselflies and will test this model against patterns of geographic variation in behavior and coloration and molecular measures of species divergence. This project will unify previous work on species interactions and their roles in the creation of biodiversity and will develop a formal model framework to guide future research on the evolutionary consequences of interspecific aggression. The project will provide interdisciplinary training to undergraduate and graduate students and includes strong international collaboration.
