Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley Dec 2017

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 …

The Global Energy Crisis, Katie Calhoun Aug 2017

The Global Energy Crisis, Katie Calhoun

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.


Recognition, Internalization, Growth: Intuitive Design For Archival Representation, Jaime L. Ganzel May 2017

Recognition, Internalization, Growth: Intuitive Design For Archival Representation, Jaime L. Ganzel

Graduate Student Symposium

Although there is a pressing need for archival description and access systems to be more intuitive and user-friendly, the uniqueness of archival records presents significant barriers to establishing simplistic and standardized conventions for the representation of archival materials. Indecipherable finding aids and access tools prevent new and inexperienced researchers from accessing the unique information and documentation held in archives. This article aims to help open the archival record to new and non-traditional archival users, support individual development of archival literacy skills, and cultivate a greater level of archival awareness in our society by developing a usable model for archivists to …
