Vegetation, Bryophytes, Lichens, Environment, and Stand Dynamics in Forests of the Swan Valley, Montana

Creator:: McCune, Bruce and Antos, Joseph A.
Abstract:: We sampled vegetation, bryophytes, lichens, environment, and stand dynamics in 56 plots in the Swan Valley, Montana in 1975-1978. The data include complete inventory of trees in 375 m2 plots, with whole-plot ocular estimates of plant cover by species, transect sampling of the ground layer bryophytes and lichens with microplots,...

Anatomical changes in the secondary phloem of grand fir (Abies grandis (Dougl.) Lindl.), induced by the balsam woolly aphid (Adelges piceae Ratz.)

Creator:: Saigo, Roy Hirofumi
Abstract:: The balsam woolly aphid (Adelges piceae Ratz.) feeds by inserting its stylets intra- and intercellularly into the cortex or outer phloem of the true firs. While feeding, the aphid injects into the bark an unknown stimulatory substance which affects the adjacent cortical parenchyma cells, the activity of the vascular cambium...

Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission

Creator:: Siegel, D. A., Behrenfeld, Michael J., Maritorena, S., McClain, C. R., Antoine, D., Bailey, S. W., Bontempi, P. S., Boss, E. S., Dierssen, H. M., Doney, S. C., Eplee, R. E. Jr., Evans, R. H., Feldman, G. C., Fields, E., Franz, B. A., Kuring, N. A., Mengelt, C., Nelson, N. B., Patt, F. S., Robinson, W. D., Sarmiento, J. L., Swan, C. M., Werdell, P. J., Westberry, T. K., Wilding, J. G., and Yoder, J. A.
Abstract:: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary...

Length Bias Correction in Gene Ontology Enrichment Analysis Using Logistic Regression

Creator:: Mi, Gu, Di, Yanming, Emerson, Sarah, Cumbie, Jason S., and Chang, Jeff H.
Abstract:: When assessing differential gene expression from RNA sequencing data, commonly used statistical tests tend to have greater power to detect differential expression of genes encoding longer transcripts. This phenomenon, called "length bias", will influence subsequent analyses such as Gene Ontology enrichment analysis. In the presence of length bias, Gene Ontology...

Investigations of Black Leg and Light Leaf Spot on Brassicaceae Hosts in Oregon

Creator:: Claassen, Briana J.
Abstract:: The Pacific Northwest is an internationally important region for the production of Brassica seed and other seed crops including grass seed. Oregon lawmakers mandated research into the co-existence of canola (Brassica napus) with other Brassica production in the Willamette Valley and House Bill 2427 was signed into law in 2013,...

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...

Recruitment predictors of an endangered prairie species : a case study of Erigeron decumbens

Creator:: Gallagher, Katie J.
Abstract:: Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...
