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。我们一方面推断系谱关系，另一方面研究这些植物繁殖的特殊过程，因为它们既有性繁殖又无性繁殖。这些小，杂草丛生的树木在玫瑰家庭是密切相关的萨斯卡通，苹果，梨，以及许多观赏树木和灌木。我们所学到的东西对那些为了果实而种植这些树木的人可能是有益的，因为它们可能提供草药，或者是为了美化环境。它同样对那些关心野生动物覆盖和食物来源管理的人有潜在的用处。我们的研究也是加拿大和世界各地的一个项目的一部分，以编目和了解生物多样性。
