Ecophysiology of the cyanolichen Lobaria oregana

Creator:: Antoine, Marie E.
Abstract:: This thesis consists of three manuscripts describing ecophysiological research on the cyanolichen Lobaria oregana. The first manuscript includes a re-evaluation of the assumptions underlying past estimates of N fixation by this species and provides an estimate of annual N fixation at the Wind River Canopy Crane (WRCC). Based upon litterfall...

Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Comparative anatomical study of three species of Microseris

Creator:: Soedjono, Estiti Harti
Abstract:: Three growth forms of the genus Microseris, of the tribe Cichorieae, family Compositae, were compared with respect to their anatomical structure. The purpose of this study was to clarify lines of evolutionary specialization in the genus. Two of the three species studied, M. laciniata and M. borealis, are perennials, while...

Castilleja and Pedicularis are confirmed as telial hosts for white pine blister rust in whitebark pine ecosystems of Oregon and Washington

Creator:: Mulvey, Robin L.
Abstract:: The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

Systematics of the genus Otidea in the Pacific Northwest

Creator:: Peterson, Eric T.
Abstract:: The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...

Taxonomy of Phacelia section Miltitzia (hydrophyllaceae)

Creator:: Halse, Richard R.
Abstract:: A systematic study was made of the species comprising Phacelia section Miltitzia. These species, which are commonly found in the Great Basin physiographic province of western North America, are distinguished from other members of Phacelia by their yellow, marcescent corollas and their transversely corrugated seeds. This project utilized morphological, cytological,...
