This award will support collaborative research between Dr. Thomas J. Hilbish, University of South Carolina, and Dr. Brian Bayne, Institute for Marine Environmental Research, Plymouth, England. The objective of the research is to investigate the genetic basis of physiological variation in two species of the mussel Mytilus in an area of apparent hybridization in southwest England. The research represents a unique opportunity to analyze the behavior of potential gene complexes in traits known to be important to the survival of an organism in its natural environment. In addition the work should shed light on the dynamics of gene flow in an area of species overlap. Genetic and physiological differentiation occurred between allopatric populations of Mytilus during the Pleistocene. One taxon occurs predominantely in cold-water, while the other is a warm-water form. In southwest England the two taxa hybridize and certain populations provide an array of genotypic combinations that will allow the investigators to analyze the genetics of physiological differentiation of the two taxa. The investigators will utilize physiological traits that may explain the differences in biogeography of the two taxa. This project will benefit from Dr. Bayne's expertise in evolutionary physiology of the Dr. Hilbish's background in physiological-evolutionary genetics.

该奖项将支持南卡罗来纳大学 Thomas J. Hilbish 博士和英国普利茅斯海洋环境研究所 Brian Bayne 博士之间的合作研究。 该研究的目的是调查英格兰西南部明显杂交地区两种贻贝生理变异的遗传基础。 这项研究提供了一个独特的机会，可以分析已知对生物体在自然环境中的生存至关重要的潜在基因复合体的行为。 此外，这项工作应该揭示物种重叠区域基因流动的动态。 在更新世期间，贻贝的异域种群之间发生了遗传和生理分化。 一种分类单元主要出现在冷水中，而另一种则出现在温水中。 在英格兰西南部，这两个类群杂交，某些种群提供了一系列基因型组合，使研究人员能够分析这两个类群生理分化的遗传学。 研究人员将利用可能解释这两个类群生物地理学差异的生理特征。 该项目将受益于贝恩博士在进化生理学方面的专业知识以及希尔比什博士在生理进化遗传学方面的背景。
