Item Open Access Hybridization between spotted knapweed (Centaurea stoebe) and diffuse knapweed (Centaurea diffusa): patterns and implications for invasion(Colorado State University. Libraries, 2008) Blair, Amy C., author; Hufbauer, Ruth, advisorHybridization is an evolutionary force that has the potential to alter invasion dynamics. Centaurea diffusa Lam. (diffuse knapweed) and C. stoebe L. (spotted knapweed) are two problematic invasive weeds in western North America. Anecdotal information suggested these two plants were hybridizing in the introduced range. The overall goal of my dissertation was to examine the patterns of hybridization in the introduced and native ranges in the field and at the molecular level, and determine if hybridization was altering the invasion of either species.
