A 21-year record of butterfly faunal composition and seasonality has been obtained along an environmental gradient across northern California, from sea level over the crest of the Sierra Nevada. Some 175 species have been monitored. This data set potentially bears on many ecological questions, including the nature and stability of interspecific association, the determinants of biological seasonality, the sensitivity of species to fluctuations in weather and the potential of entire faunas to respond to directional climatic change. The data are in binary (presence- absence) form, and satisfactory statistical methods for extracting such information from them need to be developed, tested and refined. Recent advances in a method called "conjunction analysis" are encouraging. This project will maintain the established sampling program. %%% Research projects of this type are, in addition to being important to basic ecology, of significance to the better management and conservation of vulnerable species. Additionally, such studies may bear on pest management approaches for agriculture since many butterflies and moths can reach epidemic densities.

蝴蝶区系组成和季节性的21年记录 已获得沿着环境梯度横跨北方 加州，从海平面到内华达州山脉的顶峰。 已监测到175个物种。 这个数据集可能 与许多生态问题有关，包括自然和 种间联结的稳定性， 生物季节性，物种对波动的敏感性 以及整个动物群的潜力， 定向气候变化 数据为二进制（存在- 不存在）的形式，以及令人满意的统计方法提取 这些信息需要得到开发、测试和 完善. “合取”方法的最新进展 “分析”令人鼓舞。 该项目将保持 制定抽样方案。 %%% 这种类型的研究项目，除了是重要的 基本生态学，对更好地管理和 保护脆弱物种。 此外，这些研究 可能会影响农业害虫管理方法，因为许多 蝴蝶和飞蛾会达到流行的密度。
