Lice are parasites of birds and mammals that spend their entire life cycle on the body of the host. Their close association with the host has resulted in pronounced host specificity and cospeciation in some groups. Indeed, lice are a model system used in the development of analytical methods for assessing patterns and rates of cospeciation, as well as investigations into ecological factors governing speciation. In stark contrast to other louse systems, the lice in genus Brueelia appear to show a lack of cospeciation despite a high degree of host specificity. Unfortunately, the use of Brueelia as a model is hampered by poor taxonomy. The PIs will revise the taxonomy of Brueelia, reconstruct its evolutionary history, and investigate the relative importance of co-speciation, host-switching, and host biogeography in the evolution of this hyper-diverse genus.Data, species keys, and results from the proposed project will be disseminated in scientific publications and websites. The PIs will host a workshop on the use of interactive keys, molecular, morphological and bibliographic databases at the "International Congress on Phthiraptera", which they will co-host in Utah in 2014. The PIs will work in collaboration with the Utah Museum of Natural History to produce a "Teaching Toolbox" that uses parasites to address key biological topics. The toolbox will be deposited at the Utah Museum of Natural History and made freely available to teachers across the state of Utah.

虱子是鸟类和哺乳动物的寄生虫，它们的整个生命周期都在宿主身上度过。它们与宿主的密切联系导致了某些群体中明显的宿主专一性和同种异质性。事实上，虱子是一种模型系统，用于开发分析方法，以评估共物种形成的模式和比率，以及调查支配物种形成的生态因素。与其他虱子系统形成鲜明对比的是，布鲁氏虱属的虱子尽管具有高度的宿主特异性，但似乎缺乏共种。不幸的是，Brueelia作为模型的使用受到较差的分类学的阻碍。PIS将修订布鲁氏菌的分类，重建其进化史，并调查共同物种形成、宿主转换和宿主生物地理在这个高度多样化的种群进化中的相对重要性。拟议项目的数据、物种检索表和结果将在科学出版物和网站上传播。私人投资机构将在2014年于犹他州共同主办的“国际鳞翅目昆虫大会”上主办一次关于使用交互关键字、分子、形态和书目数据库的研讨会。PIS将与犹他州自然历史博物馆合作，制作一个使用寄生虫来解决关键生物学主题的“教学工具箱”。工具箱将存放在犹他州自然历史博物馆，供犹他州各地的教师免费使用。
