Dissertation Research: Population Variation in Predation Effects on the Life History and Ecology of the Salamander Desmognathus quadramaculatus.

PI的将研究如何捕食溪流鱼类将影响生存antipredator行为，和蝾螈幼虫的幼虫生长。 将探讨如何捕食作为一个空间显性和可变的选择剂可能是区分亚种群的蝾螈Desmognathus quadramaculatus。 该物种与阿巴拉契亚山脉南部溪流中的溪流鱼共存，这项工作将提供一个独特的测试案例，以询问捕食是否会影响具有复杂生命周期的动物的生活史特征。

The PI's will study how predation by stream fish will affect survivorship antipredator behavior, and larval growth of salamander larvae. The will investigate how predation as a spatially explicity and variable selective agent may be differentiating sub-populations of the salamander Desmognathus quadramaculatus. This species co-exists with stream fish in southern Appalachian streams and this work will provide a unique test case to ask if predation influences life history traits in animals with complex life cycles.
