This study seeks to understand how variations in climatic conditions alter the reproductive cycles in three populations of white-crowned sparrows living in diverse habitats within a relatively small area of western Washington state. The research will integrate field and laboratory studies on reproductive function. Comparisons between populations will be made of behavior and reproductive state in the springtime and experimental manipulations of environmental cues suspected of signaling environmental change will be performed. The long range goal of the project is to determine the extent and function of pathways in the brain of these animals for environmental signals that regulate changes in appearance and behavior. Such information is critical to understand, in general, how animals react to their habitat to aid us in the future in solving problems associated with global warming and habitat destruction. Understanding the mechanisms by which vertebrates transform environmental information into morphological, physiological and behavioral adjustments may help us evaluate the extent to which species are able to adapt and how we may fare in a changing environment.

本研究旨在了解气候条件的变化如何改变三个种群的白冠麻雀生活在不同的栖息地内的一个相对较小的地区西部华盛顿州的生殖周期。这项研究将结合关于生殖功能的实地和实验室研究。 将进行人群之间的比较 行为 和 生殖状态 的 春天 并将对怀疑是环境变化信号的环境线索进行实验操作。该项目的长期目标是确定这些动物大脑中环境信号通路的范围和功能， 调节 外观变化， 行为 这些信息对于了解动物对栖息地的反应至关重要，有助于我们在未来解决与全球变暖和栖息地破坏相关的问题。 了解脊椎动物将环境信息转化为形态，生理和行为调整的机制可能有助于我们评估物种能够适应的程度以及我们如何在不断变化的环境中生存。
