Taxomony and mycorrhizal ecology of the desert truffles in the genus Terfezia

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...

Classification of native vegetation of Oregon

Creator:: Kagan, James S., Christy, John A., Murray, Michael P., Titus, Jonathan A., Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: This classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were an important part of the presettlement landscape of Oregon. It serves as an index to the diversity, distribution and relative rarity of the state's native plant associations, and...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Vegetation and ecological characteristics of mixed-conifer and Red Fir forests at the Teakettle Experimental Forest

Creator:: North, Malcolm, Oakley, Brian, Chen, Jiquan, Erickson, Heather, Gray, Andrew, Izzo, Antonio, Johnson, Dale, Ma, Siyan, Marra, Jim, Meyer, Marc, Purcell, Kathryn, Rambo, Tom, Rizzo, Dave, Roath, Brent, and Schowalter, Tim
Abstract:: Detailed analysis of mixed-conifer and red fir forests were made from extensive, large vegetation sampling, systematically conducted throughout the Teakettle Experimental Forest. Mixed conifer is characterized by distinct patch conditions of closed-canopy tree clusters, persistent gaps and shrub thickets. This heterogeneous spatial structure provides contrasting microclimate, habitat and resource conditions...

A plant association classification for McDonald-Dunn Forest

Creator:: Hubbard, Connie J.
Abstract:: The purpose of this study was to develop a plant association classification for the mature coniferous forests of the McDonald and Paul M. Dunn Research Forests. A secondary objective was to quantify diversity within the plant associations. This Forest is approximately 11,000 acres and is located 6 miles to the...
