Realized and potential climate responses of lichen and bryophyte communities in a national forest inventory

Creator:: Smith, Robert J.
Abstract:: Climate and terrestrial vegetation have had mutual feedbacks for nearly five hundred million years, yet both are now departing from recent historical norms, with uncertain implications for forest ecosystems. This dissertation outlines the current and potential future climate responses of lichen and bryophyte communities in the United States as part...

Tackifier Type and Concentration have Varying Impacts on Growth of Dryland Mosses

Creator:: Blankenship, Wyatt D.
Abstract:: There is growing interest in using biocrusts (assemblages of cyanobacteria, lichens, mosses, and other taxa in various proportions covering the upper few millimeters of the soil surface) to assist in restoring ecosystem function and native plant communities in dryland ecosystems. Biocrusts can be transplanted and established using jute or thatch,...

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....

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 Studies of Tropical Dry Forest: A Systematic and Ecological Approach

Creator:: Miranda-González, Ricardo
Abstract:: In recent years, our ecological knowledge of tropical dry forests has increased dramatically. However, whole components of the ecosystem, like lichenized fungi, remain mostly unknown. Crustose lichens in these forests are so abundant, that they are responsible for the characteristic appearance of a “white bark forest” during the dry season....

Epiphytic macrolichens in relation to forest management and topography in a western Oregon watershed

Creator:: Berryman, Shanti D.
Abstract:: This dissertation describes patterns in epiphytic macrolichen community composition, diversity, and biomass across various stand types in the Blue River watershed of western Oregon. It first examines the relative importance of ecological factors such as stand age, remnant tree retention, and topography to lichen communities in the landscape. It then...

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,...

Decadal Changes in Lichen and Vegetation Communities in Relation to Metal Deposition and Climate in Northern Alaska

Creator:: Di Meglio, Elisa B.
Abstract:: The Red Dog Mine transports concentrated zinc and lead ore in northwestern Alaska through Cape Krusenstern National monument along a haul road. High metal levels in the moss Hylocomium splendens along the haul road have been attributed to ore dust released during transport. The mine has implemented several pollution abatement...

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...
