The association of epiphytic macrolichens and bryophytes with riparian stand types along a valley continuum, Oregon Coast Range

Creator:: Ruchty, Andrea M.
Abstract:: I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...

Recruitment predictors of an endangered prairie species : a case study of Erigeron decumbens

Creator:: Gallagher, Katie J.
Abstract:: Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...

An evaluation of the invasion potential of Kochia prostrata (forage kochia) in southwestern Idaho, USA

Creator:: Gray, Erin C.
Abstract:: Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Insights into the pathology and epidemiology of Phytophthora ramorum, causal agent of sudden oak death

Creator:: Daniels, Hazel A.
Abstract:: Sudden oak death is caused by the clonally reproducing generalist oomycete Phytophthora ramorum. The pathogen can infect more than 130 different plant hosts including Quercus spp., Larix kaempferi, and Notholithocarpus densiflorus, as well as common nursery genera such as Rhododendron and Camelia, where it causes symptoms ranging from bleeding cankers...

Biology of sweet cherry powdery mildew

Creator:: Calabro, Jill M.
Abstract:: The Pacific Northwest has become one of the nation’s premier sweet cherry, Prunus avium, production areas. As production of sweet cherries has flourished in Oregon and Washington, so has powdery mildew, caused by the fungus Podosphaera clandestina, which infects both foliage and fruit causing severe economic damage to growers. Sweet...

Integration of Evolutionary Theory and Genomics to Understand Processes Involved in Host Adaptation and Divergence in Phytophthora Plant Pathogens

Creator:: Tabima, Javier F.
Abstract:: Modern plant pathology benefits from integrating methods and concepts from evolutionary biology. For example, evolutionary concepts are used to identify and examine species boundaries of plant pathogens, recognize processes underlying pathogen biogeography, identify traits that characterize emerging species, and discover new molecular interactions that originate under processes of selection. In...

Abstract:: Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...

Shrub epiphyte communities in relation to stand management in forests of western Oregon

Creator:: Rosso, Abbey L.
Abstract:: This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...

Factors limiting the distribution of the sensitive lichen Usnea longissima in the Oregon Coast Range : habitat or dispersal?

Creator:: Keon, Dylan B.
Abstract:: The sensitive lichen Usnea longissima Ach., formerly a fairly common circumboreal species, has been extirpated from much of its range (e.g., Eastern Europe). Although the U.S. Pacific Northwest (PNW) remains a relative stronghold for the species, U longissima faces increasing pressure in the region from habitat loss, air pollution, and...
