项目摘要

A major goal of evolutionary biology is to develop concepts that can be used to address specific questions. An important concept in evolutionary biology is that the characteristics of organisms are well matched (i.e., co-adapted) to each other. For example, the thermoregulatory behavior of reptiles with bacterial infections matches the temperature at which their immune systems function best. The purpose of this study is to determine to what extent the concept of co-adaptation can be applied to the thermal biology of reptiles. Because reptiles obtain most of their body heat from the environment, describing their temperature relationships is critical to understanding their ecology. We will address the relationship between the nocturnal snakes that exhibit unusually low body temperature during activity. We will surgically implant temperature-sensitive radiotransmitters in snakes to determine their body temperatures in the field. In the laboratory, we will study the effects of variation in body temperature on snake physiology (e.g., digestive rate, metabolism, crawling speed). Through statistical comparisons of body temperatures and their effects on physiology, we will determine the extent of co- adaptation in rubber boas. Our analytical methods also will provide a framework for future studies of co-adaptation.

进化生物学的一个主要目标是发展概念，可用于解决具体问题。中的一个重要概念进化生物学认为生物体的特征良好匹配（即，互相适应）。比如说细菌感染爬行动物的体温调节行为与它们的免疫系统运作的温度相匹配最好这项研究的目的是确定在多大程度上，共同适应的概念可以应用于热生物学，爬行动物因为爬行动物的大部分体热来自环境，描述它们的温度关系至关重要了解它们的生态。我们会处理好在夜间活动的蛇，活动期间的温度。我们将通过手术植入蛇体内的温度敏感的无线电发射器，他们的体温在实验室里，我们将研究体温变化对蛇的影响生理学（例如，消化率、代谢、爬行速度）。通过对体温和体温变化的统计比较，对生理的影响，我们将确定共同的程度，在橡胶博阿斯适应。我们的分析方法也将提供未来共同适应研究的框架。
