Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley
Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley
WWU Honors College Senior Projects
Arbuscular mycorrhizal fungi (AMF) form mycorrhizae, a common, well-studied symbiotic relationship. Controls on the magnitude and direction of plant mycorrhizal growth response (MGR) remain obscured. Specifically, the influence of light availability in the MGR of an invasive forb, spotted knapweed Centaurea stoebe, has not been studied. Greenhouse studies exploring the growth response of knapweed to arbuscular mycorrhizae (AM) often fail to report light intensity levels, which could impact the quality of their data. I conducted a greenhouse experiment studying the MGR in spotted knapweed under shaded and unshaded conditions, designed to approximate light availability in ambient greenhouse and full-sun …

Facing the Future Lessons
The world is at an energy tipping point. Countries and communities can choose to be proactive or wait and be reactive, however it is much less costly to do the former. In this project, high school environmental science students will examine the current energy use and concerns in a named country or community, analyze the pros and cons of the current energy situation and how it effects the social, economic and environmental aspects of the culture, then create a more sustainable, resilient plan for that country.
