0129319FewellThis award supports Jennifer Fewell and graduate and undergraduate students from Arizona State University in a collaboration with Juergen Gadau of Institute for Behavioral Physiology at the University of Wuerzburg, Germany. The aim of the international project is to examine the extent and consequences of hybridization between two native seed-harvester ants, Pogonomyrmex rugosus and Pogonomyrmex barbatus. The German and U.S. groups will test the hypothesis that hybridization in that system does not universally produce reduced hybrid fitness, as expected by current models. They will also test the hypothesis that colonies respond to hybridization by preferentially using sperm belonging to different species. They will use morphological, molecular, and behavioral techniques to determine the extent of introgression between species and to measure fitness components of hybridized and parental colonies. In addition, they will perform controlled mating experiments to determine the effect of hybridization on caste determaination. The work plan provides for extensive participation by graduate students in the international travel and research.

0129319 Fewell这个奖项支持詹妮弗Fewell和研究生和本科生从亚利桑那州州立大学在一个合作的行为生理学研究所的Juergen Gadau在维尔茨堡大学，德国。 该国际项目的目的是研究两种本地种子收获蚁Pogonomyrmex rugosus和Pogonomyrmex vanatus之间杂交的程度和后果。 德国和美国的研究小组将检验这样一个假设，即该系统中的杂交并不像当前模型所预期的那样普遍产生杂交适应性降低。 他们还将测试一个假设，即菌落对杂交的反应是优先使用属于不同物种的精子。 他们将使用形态学，分子和行为技术来确定物种之间的渗入程度，并测量杂交和亲本菌落的适合度。 此外，他们将进行控制交配实验，以确定杂交对种姓决定的影响。工作计划规定研究生广泛参与国际旅行和研究。
