A comparison of soil microfungi in forest stands of Red Alder, Conifer, and Alder-Conifer mixtures

Creator:: Wicklow-Howard, Marcia C. (Marcia Cope) 1943-
Abstract:: The species composition of soil microfungal populations in-adjacent stands of red alder, conifers, and mixed alder conifer correlated strongly with the dominant vascular vegetation. A total of 92 species were isolated: 55 from the alder stand; 45 from the conifers; and 46 from the mixed alder-conifer, with few species (16,...

Rhizosphere microfloras associated with mycorrhizae of Douglas-fir and red alder

Creator:: Neal, John Lloyd
Abstract:: The mycorrhizal rootlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) and red alder (Alnus rubra Bong.) were extensively investigated. A jet-black mycorrhiza was found to be dominant on Douglas-fir rootlets. The fungal symbiont was identified as Cenococcum graniforme (Sow.) Ferd. and Winge. Two forms of mycorrhizae predominated on root systems of...

Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

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;...

Primary succession on a receding glacier forefront : with special emphasis on root-colonizing fungi

Creator:: Jumpponen, Ari
Abstract:: Plant succession is among the fundamental concepts in ecology. Studies addressing plant recruitment, successional mechanisms, and the role of root-colonizing fungi with focus on dark-septate endophytes (DSE) were conducted in the laboratory and on the forefront of receding Lyman Glacier (North Cascade Range, Washington, U.S.A.). Primary successional studies primarily focus...

Seasonality as a driving factor of decomposition pathways in both meadows and forests : an exploration across a gradient of climate in Oregon

Creator:: Colby, Samantha E.
Abstract:: Soil food webs process the majority of terrestrial carbon, and influence overall ecosystem function. A primary distinction among soil food webs is based on fungal versus bacterial pathways of decomposition; these lead to fundamentally different soil function, and are expected to differ in dominance between meadows and forests. This assumption...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Ecological survey of fungi active in western coniferous forest soils

Creator:: Denison, William C., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: During Biome 1, our primary objective was identification of the dominant fungi involved in litter decomposition. Two survey methods were used: (1) a survey of macrofungi occurring on Watershed 2 based on fruiting bodies collected and cultures; and (2) a survey of microfungi on decomposing foliage based on cultures isolated...
