Effectiveness of Root-Boring Knapweed Weevil (Cyphocleonus achates Fåhr.) Herbivory on Spotted Knapweed (Centaurea stoebe Lam.) in Kamloops, BC: A Five-year Review
Spotted knapweed (Centaurea stoebe) is an Eurasian plant now invasive across North America. The root-boring knapweed weevil (Cyphocleonus achates) is one of 13 approved biocontrol agents. In 2017 and 2018, root-boring knapweed weevils were released at 15 sites across Kamloops, BC, Canada. This …

Catechin, a novel root exudate of Centaurea stoebe, exhibits pleiotropic effects on the soil microbial community and individual soil isolates, and undergoes chemical changes with numerous abiotic factors from soil
Allelopathy has been studied for (±)-catechin, a root exudate of spotted knapweed, as a plausible mechanism that facilitates knapweed invasion in North America. Phytotoxic effects are observed in invaded fields as well as greenhouse experiments when employing catechin or growing spotted knapweed, …

Interplay between competition and evolution in invaded and native plant communities
… spicata when competing with the invasive Centaurea stoebe. I found that tolerance had far greater fitness benefits than suppression. This observation has important consequences for understanding the outcome of evolution in plant communities. In my third chapter, I investigated the …

Impact of Roadside Maintenance Practices on Larinus minutus (Gyllenhal), a Biological Control Agent of Spotted Knapweed
<p>Spotted knapweed, Centaurea stoebe, is an invasive weed found throughout much of the United States. Spotted knapweed is a rangeland weed where it was originally introduced into western North America in the 1880s.Where spotted knapweed spread to the southeastern U.S., it is found mostly along …

Using patchy plant invasions to understand how diffuse interactions modify facilitation and competition
… distributions of two invasive exotic plants, <i>Centaurea stoebe</i> and <i>Bromus tectorum</i>, to explore conditionality in plant interactions and the implications of this conditionality for community invasibility. Additionally, I expanded this research to investigate how these two invaders …
