In nature, yeasts in the subdivision Ascomycota are found mostly at the interface between insects and plants, as for example in nectar or the sap of injured trees. In the last decade, my students and I have shown that the interaction of yeasts with small sap beetles that inhabit short-lived flowers is highly specific. Some of our work has been pivotal in demonstrating that the traditional view that all microbes are everywhere is no longer tenable. The currently proposed research aims at determining some of the factors that determine specificity.

在自然界中，子囊菌纲的酵母菌主要存在于昆虫和植物的交界处，例如在花蜜或受伤树木的汁液中。在过去的十年里，我和我的学生们已经证明，酵母与栖息在短命花朵上的小汁液甲虫的相互作用是高度特异性的。我们的一些工作在证明所有微生物无处不在的传统观点不再站得住脚方面起到了关键作用。目前提出的研究旨在确定一些决定特异性的因素。
