9321323 Wake This is a proposal to study the role of the environment in generating differences among organisms, using the salamander family Plethodontidae as a model. The project will examine the reaction norm (range of differences) of number of trunk vertebrae with respect to developmental temperature in the salamander family Plethodontidae. Reaction norms will be determined by raising clutches in different temperature environments. These data will then be examined within the framework of a phylogenetic (genealogical) hypothesis for these salamanders. %%% This work will reveal 1) basic patterns of change in this anatomical system, particularly in the amount of plasticity as determined by environmental variance; 2) the causal basis of geographic variation in the salamander genus Batrachoseps; and 3) the relationship of plasticity to among-species variation in number of trunk vertebrae and other anatomical traits. This will shed much light on the phenomenon of anatomical plasticity in reaction norms in vertebrates.

小行星9321323 这是一项以蝾螈科Plethodontidae为模型，研究环境在生物体之间产生差异方面的作用的建议。 该项目将研究蝾螈科Plethodontidae的躯干椎骨数量与发育温度的反应规范（差异范围）。 反应规范将通过在不同温度环境下升高离合器来确定。 这些数据，然后将检查这些蝾螈的系统发育（系谱）假说的框架内。 %%% 这项工作将揭示1）在这个解剖系统的变化的基本模式，特别是在可塑性的量，由环境变化决定; 2）在蝾螈属Batrachoseps地理变异的因果关系;和3）可塑性的关系，躯干椎骨的数量和其他解剖特征的物种变异。 这将为脊椎动物反应规范的解剖可塑性现象提供更多的线索。
