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,...

Variation in metabolism, thallus characteristics, and water relations of three populations of Loboria pulmonaria from western Oregon

Creator:: Neil, Garry Allen
Abstract:: A physio-ecological study of Lobaria pulmonaria (L. ) Hoffm. was done to determine if geographic variation occurred within the species. Lobaria pulmonaria was collected from Table Mountain, Oak Creek, and Lost Prairie, located in the Coast Range, Willamette Valley, and Cascade Range respectively in Western Oregon. During 1971 and 1972...

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...

Pendent Usnea (Lichens; Ascomycetes; Parmeliaceae) in Western Oregon : taxonomy; morphological characters; and geographical distribution

Creator:: Pittam, Sherry K.
Abstract:: Pendent Usnea species were collected in western Oregon and examined. Character states, such as cortex-medulla-axis ratio; fibril length; papilla diameter; branching patterns; and presence or absence of fibrils, papillae, soredia, isidia; plus chemistry, were recorded and analyzed by inspection for differences. Historical names were researched in the literature. A comparison...

Clonal variation in Russet Norkotah and Umatilla Russet potato varieties

Creator:: Brunick, Robert L.
Abstract:: These studies compared giant hill strains of Russet Norkotah and Umatilla Russet to the parent varieties. Selections were initially based on late maturity and increased vine vigor. Subsequent evaluations emphasized yield and quality parameters in comparison to the parent varieties. Giant hills were collected from the Columbia Basin and Central...

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...

Evaluating Field Production Issues by Investigating Grain Dormancy and Plant Segregation Patterns in Soft White Winter Wheat

Creator:: McCarthy, Christy A.
Abstract:: Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...

Lichen biomonitoring in southeast Alaska and western Oregon

Creator:: Derr, Chiska C.
Abstract:: Lichen sensitivity to air quality has been recognized in Europe for over 125 years: recently Federal agencies in this country have begun using lichens as air quality bioindicators. This study presents the results of three different approaches to air quality biomonitoring using lichens: (1) a lichen community analysis, (2) an...

The frequency of occurrence of corticolous lichens on Quercus garryana in the Willamette Valley

Creator:: Saxton, Robert Howard
Abstract:: This study was made to present any evidence as to differences in the frequency of occurrence of corticolous lichens from east to west in the Willamette Valley on a bark substrate of Quercus Garryana. Twenty-four species of lichens were observed to be present within the grid area of the 100...

An experimental reintroduction of Pleuropogon oregonus, a rare wetland grass native to Oregon

Creator:: Groberg, Matthew G.
Abstract:: Pleuropogon oregonus Chase is a rare wetland grass endemic to eastern Oregon. The species is composed of two widely separated populations, one in Lake County and one in Union County. In order to reduce the risk of extinction, the Oregon Department of Agriculture Native Plant Conservation Program initiated several reintroduction...
