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有害的基因变化，少数濒危物种面临灭绝的风险。 这项研究探讨了这两个因素对物种生存的相对重要性。 研究人员将利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。 结果将有助于总体了解种群规模的变化，并允许管理者制定保护这些物种和类似物种的指导方针和原则。 最后，所研究的物种之一Lesquerella humilis是一种在工业和医药方面具有潜在经济价值的替代作物物种。 Lesquerella 独特的羟基化油在制造中有多种用途。 雷斯克雷拉中的硫化合物（芥子油苷）正在作为一种潜在的抗肿瘤药物进行研究。 因此，这项研究对于保护生物学的基本理解以及实际应用的潜力具有重要意义。
