Contrasting Epiphytic and Ground Layer Macrolichen Communities along the Coast-to-inland Climatic Gradient in Oregon

Creator:: Glauser, Abby L.
Abstract:: Cyanolichens, lichens with a cyanobacterial photobiont, benefit our ecosystems by the fixation of atmospheric nitrogen into a usable form for other organisms. They are highly sensitive to air pollution and require liquid water for photosynthesis. Many cyanolichen species frequently occur on the ground in the Pacific Northwest, however, most macrolichen...

Cryptogam communities in forest and steppe ecosystems of Oregon, USA

Creator:: Root, Heather T.
Abstract:: I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...

Lichen Biomonitoring from Valley to Alpine in Central and Southern California

Creator:: Kovasi, Adrienne I.
Abstract:: In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....

Yosemite region nitrogen deposition and patterns in the composition of lichen communities

Creator:: Hutten, Martin
Abstract:: This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

Lichen Functional Trait Variation Along an East-West Climatic Gradient in Oregon and Among Habitats in Katmai National Park, Alaska

Creator:: Spickerman, Kaleigh
Abstract:: Functional traits of vascular plants have been an important component of ecological studies for a number of years; however, in more recent times vascular plant ecologists have begun to formalize a set of key traits and universal system of trait measurement. Many recent studies hypothesize global generality of trait patterns,...

Lichen communities and caribou habitat in Denali National Park and Preserve, Alaska, USA

Creator:: Nelson, Peter R.
Abstract:: Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...

Riparian lichens of northern Idaho

Creator:: Hutchinson, Jenifer L.
Abstract:: Riparian forests in the Idaho Panhandle, north of Whitebird, were surveyed for rare riparian lichen species. The region was stratified into nine geographic units and by stream size. Eighty-one plots were surveyed for lichen community, stand and river characteristics. Variables important to lichen community composition included regional differences, elevation, climatic...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

Creator:: Holt, Emily A.
Abstract:: The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...

Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:: Marks, Jade A.
Abstract:: Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....
