U.S.-Australia Planning Visit: Plant and Ecosystem Responses to Global Change

0624762韦伯斯特该奖项支持一次计划访问，使普尔曼华盛顿州立大学的迈克尔·韦伯斯特博士能够与昆士兰州凯恩斯詹姆斯·库克大学的布拉德利·康登博士和昆士兰州布里斯班格里菲斯大学的达里尔·琼斯博士以及西澳大利亚州德比市澳大利亚野生动物保护协会的莎拉·莱格会面。这次访问将促进制定一项关于澳大利亚仙女扳手的行为和物种形成的合作计划。研究将涉及生殖行为在推动种群和物种形成多样化方面的作用。生殖竞争导致性别选择，被认为是物种形成过程中的一股重要力量，但对这一关键假设的大多数支持来自广泛的比较研究。对于鸟类来说尤其如此：性别选择被认为在这一群体的多样性和物种形成中发挥着关键作用，但很少有研究考察交配信号和偏好的地理差异，也没有研究这些差异是否会导致种群之间的生殖隔离。该项目将通过直接研究交配信号和偏好在一个模型系统中的作用来研究这些问题：澳大利亚仙鹤(马鲁斯属)。这次访问将允许国际合作者团队会面，计划具体的实验，确定研究地点，并收集重要的初步数据。预计该项目将为美国研究生提供独特的培训和教育机会，以获得全球研究经验。预计各国科学家和学生之间的这些合作将导致长期的合作，这将使所有机构受益。

The visit will facilitate development of a collaborative plan on the behavior and speciation of the Australian Fairy-wren.The study will involve the role of reproductive behavior in driving diversification among populations and speciation. Reproductive competition, resulting in sexual selection, is thought to be an important force in the speciation process, but most support for this key hypothesis has come from broad comparative studies. This is particularly true for birds: sexual selection is thought to play a key role in diversification and speciation in this group, yet few studies have examined geographic variation in mating signals and preferences, nor whether these produce reproductive isolation among populations. The project will examine these issues by directly examining the role of mating signals and preferences in a model system: Australian fairy-wrens (genus Malurus). The visit will allow the international team of collaborators to meet to plan specific experiments, identify study sites, and collect important preliminary data. It is also anticipated that this project will provide unique training and educational opportunities for U.S. graduate students to obtain a global research experience. It is anticipated that these collaborations between the scientists and students from each country will lead to long-term collaborations that will benefit all the institutions.
