Small populations of endangered species risk extinction due to random changes in population size, or due to harmful genetic changes. This research examines the relative importance of these two factors for species survival. The investigators will study this question using wild populations of two rare plants species in western Montana. Results will contribute to general understanding of changes in population size, as well as allow managers to formulate guidelines and principles for preservation of these and similar species. Finally, Lesquerella humilis, one of the species to be studied, is an alternative crop species with potential economic value in industry and medicine. Unique hydroxylated oils from Lesquerella have several uses in manufacturing. Sulfur compounds (glucosinolates) from Lesquerella are being examined as a potential antitumor drug. Thus, this research has important relevance to basic understanding of conservation biology as well as potential for practical application.

由于种群规模的随机变化，或由于有害的基因变化，濒危物种的小种群面临灭绝的危险。这项研究考察了这两个因素对物种生存的相对重要性。研究人员将使用蒙大拿州西部两种稀有植物的野生种群来研究这个问题。结果将有助于对种群数量变化的总体了解，并使管理者能够制定保护这些物种和类似物种的指导方针和原则。最后，拟研究的欧氏莱斯克雷氏菌是一种具有潜在工业和医药经济价值的替代作物。莱斯克雷氏菌独特的羟基化油在制造中有多种用途。莱斯克雷氏菌中的硫化物(硫代葡萄糖苷)正在作为一种潜在的抗肿瘤药物进行研究。因此，本研究对保护生物学的基本认识和实际应用具有重要意义。
