Growth in the lichen Lobaria oregana as determined from sequential photographs

Creator:: Rhoades, Fred M. (Fred Mast)
Abstract:: The foliose lichen Lobaria oregana (Tuck.) Mti 11. Arg. is an important component of the upper canopy epiphyte community in oldgrowth Douglas fir forests of the Pacific Northwest. L. oregana contains the secondary phycobiont, Nostoc sp. , which is capable of fixing nitrogen. This thesis presents a new non-destructive method...

Lichen Biomonitoring from Valley to Alpine in Central and Southern California (version 2)

Creator:: Kovasi, Adrienne I.
Abstract:: All the datasets used in Kovasi's (2022) masters thesis. Chapter 2: The datasets are elemental concentrations for 25 elements from samples of the saxicolous lichens Umbilicaria phaea (n = 51), Rhizoplaca melanophthalma (n = 20), and the epiphytic lichen Letharia vulpina (n = 16) from the southern Sierra Nevada and...

Lichen distribution in Oregon coastal dune communities

Creator:: Leuthner, Shirley Mae
Abstract:: Distribution of lichens was studied at seven coastal dune sites in Oregon. Lichens were sampled in the dry stable, dry meadow, meadow, rush meadow, marsh, shrub and forest deflation plain communities. Observations were made of the standing water in the marsh community. Quantitative measurements were made of the percent organic...

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...

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...

Ecophysiology of the cyanolichen Lobaria oregana

Creator:: Antoine, Marie E.
Abstract:: This thesis consists of three manuscripts describing ecophysiological research on the cyanolichen Lobaria oregana. The first manuscript includes a re-evaluation of the assumptions underlying past estimates of N fixation by this species and provides an estimate of annual N fixation at the Wind River Canopy Crane (WRCC). Based upon litterfall...
