ABR: Molecular Phylogenetic Studies of Select Amphibians

在基于成就的续约中，琳达马克森博士将 继续她富有成效的研究 选择两栖动物群体的关系，强调 特别是世界上的透明蛙和肌蛙。 到 分析这些物种之间的进化差异，博士。 Maxson估计血清白蛋白中的氨基酸差异 蛋白质，使用称为微量补体的血清学技术 固定 氨基酸的差异已经被证明提供了 可靠的基因组标记 了比较 被地理或地质屏障分隔的物种之间， 已知的地质年代（例如，直布罗陀海峡）， 还将对进化事件的时间进行估计， 从而能够测试分子白蛋白时钟的想法。 最后，马克森博士将利用他的血清学天赋 来自鳄鱼研究的抗血清（爬行动物，不是两栖动物， ans）比较两种不同血清学方法的结果， 估计系统发育模式。

In an Accomplishment-Based Renewal, Dr. Linda Maxson will continue her productive investigations of the phylogenetic relationships of select groups of amphibians, emphasizing especially the hylid and myobatrachid frogs of the world. To analyze the evolutionary divergences among these species, Dr. Maxson estimates the amino acid differences in serum albumin proteins, using a serological technique known as micro-complement fixation. The amino-acid differences have been shown to provide reliable genomic markers of evolutionary descent. In comparisons between species separated by geographic or geological barriers of known geological age (for example, the Straits of Gibraltar), estimates will also be made of the timing of evolutionary events, thus enabling a test of the idea of a molecular albumin clock. Finally, Dr. Maxson will capitalize on a gift of serological antisera from a study of crocodiles (reptiles, not amphibi- ans) to compare results from two different serological methods in estimating phylogenetic patterns.
