My students and I study how hawthorns have evolved. We infer genealogical relationships on the one hand, and on the other we study the particular processes by which these plants reproduce, since they do so both sexually and asexually. These small, weedy trees in the rose family are closely related to saskatoons, apples, and pears, as well as to many ornamental trees and shrubs. What we learn is potentially of benefit to others who grow such trees for their fruit, for the herbal remedies they may provide, or for landscaping purposes. It is likewise potentially useful for people concerned with managing wildlife cover and food sources. Our studies are also part of a program in Canada and worldwide to catalog and understand biodiversity.

我和我的学生研究山楂是如何进化的。我们一方面推断家谱关系，另一方面研究这些植物繁殖的特殊过程，因为它们既有有性繁殖，也有无性繁殖。这些玫瑰家族的小杂草树与沙棘、苹果和梨以及许多观赏树木和灌木密切相关。我们所学到的对其他种植这种树的人有潜在的好处，他们种植这种树是为了果实，为了它们可能提供的草药，或者为了美化环境的目的。对于关心管理野生动物覆盖物和食物来源的人来说，它也同样有潜在的用处。我们的研究也是加拿大和世界范围内对生物多样性进行编目和了解的项目的一部分。
