SGER: Effects of Elevated C02 on Insect Herbivory in a Florida Scrub-Oak System

9633717 Stiling大气中二氧化碳（CO2）的浓度正在增加。大气中二氧化碳含量增加的影响引起了许多研究领域的极大科学兴趣。大气中二氧化碳增加的一个可能结果是植物生长速率和植物组织化学的变化。预计这将影响以这些植物为食的食草昆虫。该SGER项目利用了在佛罗里达灌木丛生态系统中进行的重复现场研究，在该生态系统中，二氧化碳浓度将在一系列大型开顶室中增加一倍。这个SGER项目将研究草食性昆虫对实验地点二氧化碳浓度升高的反应。该项目将收集必要的数据，在大规模的实地研究中提出关于昆虫食草动物与二氧化碳水平升高之间关系的具体假设。

9633717 Stiling Concentrations of carbon dioxide (CO2) in the atmosphere are increasing. The effects of this increased amount of CO2 in the atmosphere are of great scientific interest to many fields of study. One possible outcome from increased atmospheric CO2 is a change in plant growth rates and plant tissue chemistry. This is predicted to impact the herbivorous insects who feed upon these plants. This SGER project takes advantage of a replicated field study in a Florida-scrub ecosystem where CO2 concentrations will be doubled in a series of large open-top chambers. This SGER project will examine the respmnse of herbivorous insects to elevated CO2 concentrations at this experimental site. This project will gather the necessary data to develop specific hypotheses about the relationships of insect herbivores to elevated CO2 levels in a large-scale field study.
