This action funds an NSF Postdoctoral Research Fellowship in Biological Informatics for 2000.The research and training plan is in the area of Ecology and is entitled "Reconstructing Biogeography: Tree Species as a Novel Explanation for North American Bird Population Declines". One of the most visible environmental problems in eastern North America is the decline of many populations of breeding birds. While deforestation and loss of habitat have been identified as the causes for some species, they do not explain the population decline of the remainder. Important factors, such as quality of breeding habitat, have not been sufficiently studied. This research examines the alternative hypothesis that historical changes in forest composition, such as the decline of previously dominant tree species, is contributing to changes in bird populations due to species' preferences for particular trees. Examination of morphology (bill, leg, foot, wing, and tail dimensions) of various bird species allows characterization of their preferences for specific trees and in turn provides a means to identify correlations between tree species and bird species population decline.

这一行动资助了NSF 2000年生物信息学博士后研究奖学金。该研究和培训计划是在生态学领域，标题为“重建生物地理学：树种作为北美鸟类数量下降的新解释”。北美东部最明显的环境问题之一是许多繁殖鸟类的数量下降。虽然森林砍伐和栖息地丧失被认为是一些物种的原因，但它们并不能解释其余物种的数量下降。重要的因素，如繁殖生境的质量，还没有得到充分的研究。这项研究检验了另一种假设，即森林组成的历史变化，如以前占主导地位的树种的衰落，正在导致鸟类数量的变化，这是由于物种对特定树木的偏好。研究不同鸟类的形态(喙、腿、脚、翼和尾巴的尺寸)可以表征它们对特定树木的偏好，进而提供一种手段来确定树种和鸟类种群数量下降之间的相关性。
