Growth and reproductive ecology of Larix laricina in interior Alaska

Creator:: Brown, Kevin R.
Abstract:: Larix laricina in Alaska occurs on sites ranging from productive slopes and riverbottoms to wet bogs underlain by permafrost. It is largest on sites without permafrost, where it is associated with Picea glauca, but is much more common in bogs, where it occurs with Picea mariana. In this study, I...

Evaluation of Grape Rootstocks for Resistance to Crown Gall and Nematodes [1996-1997]

Creator:: Pinkerton, Jack and Miller, Marilyn
Abstract:: The nng nematode, Cnconenwlla xenoplax, has been reported to depress the vigor and yields of grapevines in Europe, California, Washington, and Michigan. Population densities of 500 C. xenoplax per kg of soil have reported to reduce vine yield 10-25% in California. A survey of Oregon vineyards found C. xenoplax in...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Maize Metabolic Network Construction and Transcriptome Analysis

Creator:: Monaco, Marcela K., Sen, Taner Z., Dharmawardhana, Palitha D., Ren, Liya, Schaeffer, Mary, Naithani, Sushma, Amarasinghe, Vindhya, Thomason, Jim, Harper, Lisa, Gardiner, Jack, Cannon, Ethalinda K.S., Lawrence, Carolyn J., Ware, Doreen, and Jaiswal, Pankaj
Abstract:: A framework for understanding the synthesis and catalysis of metabolites and other biochemicals by proteins is crucial for unraveling the physiology of cells. To create such a framework for Zea mays L. subsp. mays (maize), we developed MaizeCyc, a metabolic network of enzyme catalysts, proteins, carbohydrates, lipids, amino acids, secondary...

Hypogymnia in the Himalayas of India and Nepal

Creator:: McCune, B., Divakar, P. K., and Upreti, D. K.
Abstract:: Morphological and chemical studies of Hypogymnia from the Himalayas revealed one new species, three species new to the region, and a previously unrecognized synonym. Hypogymnia crystallina, distinguished by its rimmed holes in the lobe axils, a pruinose disc, POL+ epihymenium, and distinctive chemistry (zeorin, hypoprotocetraric acid, usnic acid and atranorin)...

The genus Leucogaster (Basidiomycetes, Leucogastraceae)

Creator:: Fogel, Robert Dale
Abstract:: Three provisional species are described as new: Leucogaster couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida is transferred to Leucogastef, completing the transfer of all Leucophlebs species to Leucogaster. L. columellatus is transferred to Sclerogaster. L. longisterigmatus is synonymized with L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:: Lewis, Katherine JoAnn
Abstract:: The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...
