Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...

Effect of resident epiphytic fungi development of brown rot blossom blight of stone fruits

Creator:: Wittig, Hans P. P.
Abstract:: Antagonistic effects of Epicoccum purpurascens, Aureobasidium pullulans, Trichoderma spp., and Botrytis cinerea on establishment of Monilinia fructicola infections in cherry and peach blossoms were assessed in field and mist chamber studies. Conidia of each fungus were applied to blossoms that were subsequently inoculated with conidia of M fructicola. Mist chamber...

Creator:: McKernan, Brie-Anne
Abstract:: In the wetland prairie of William L. Finley National Wildlife Refuge (FNWR) in western Oregon, we investigated the response of Delphinium pavonaceum Ewan (peacock larkspur, Ranunculaceae), an endangered perennial forb, to four unreplicated dormant season fire regimes of 0, 2, 4, or 10 fires that were applied over a 12-year...

Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Using local climate to explain temporal variation in rare plant populations

Creator:: Pfingsten, Ian A.
Abstract:: Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...
