This action funds an NSF Postdoctoral Research Fellowship for FY 2010. The fellowship supports a research and training plan entitled "Landscape genetic modeling of environmentally associated morphological and genetic variation" for Ian Wang. The host institution for this research is Harvard University, and the sponsoring scientist is Jonathan Losos. To date, the vast majority of landscape genetics research has focused on the relationship between population genetic structure and geographic distance, without considering the potential effects of environmental variation. Structural equation modeling (SEM), which utilizes a series of regression and model-fitting analyses to test hypotheses about the relationships between multiple variables, provides a logical framework for examining associations between geographic distance, ecological differences, and genetic structure. This research utilizes a computationally intensive SEM analysis and data acquired from five major DNA, GIS, and museum record databases to test whether patterns of genetic structure in 12 species of Anolis lizards are associated with between-population geographic distance or ecological differences. The implementation of this method substantially expands the scope of landscape genetics, allowing researchers to examine consequential questions in the study of biological diversification, including whether intra-specific genetic structure is correlated with geographic distance or ecological differences, and which ecological axes are associated with genetic differentiation in each of these species. Training goals include gaining expertise in evolutionary ecology and in modeling and analyzing ecological traits and the interactions between organisms and their environments. Broader impacts include contributing materials to museum displays, including a planned exhibit on Anolis lizards at the Harvard Museum of Natural History, and involving underrepresented undergraduate students in several of the diverse components of this research.

该行动为2010财年的NSF博士后研究奖学金提供了资金。该奖学金支持伊恩·王（Ian Wang）的题为“环境相关的形态和遗传变异的景观遗传建模”的研究和培训计划。这项研究的主持机构是哈佛大学，赞助科学家是乔纳森·洛索斯（Jonathan Losos）。 迄今为止，绝大多数景观遗传学研究都集中在种群遗传结构与地理距离之间的关系，而无需考虑环境变化的潜在影响。 结构方程建模（SEM）利用一系列回归和模型拟合分析来测试有关多个变量之间关系的假设，为检查地理距离，生态差异和遗传结构之间的关联提供了一个逻辑框架。 这项研究利用了从五个主要DNA，GIS和博物馆记录数据库中获得的计算密集的SEM分析和数据，以测试12种Anolis Lizards中的遗传结构模式是否与人口间的地理距离或生态差异有关。 该方法的实施实质上扩大了景观遗传学的范围，使研究人员能够在生物多样化的研究中检查结果性问题，包括特异性遗传结构是否与地理距离或生态差异相关，以及哪些生态轴与这些物种中每个物种的遗传差异都相关。 培训目标包括在进化生态学以及建模和分析生态特征以及生物体及其环境之间的相互作用方面获得专业知识。 更广泛的影响包括为博物馆展示贡献材料，包括在哈佛大学自然历史博物馆举行的计划展上的展览，并涉及代表性不足的本科生参与这项研究的几个不同组成部分。
