Supporting a Culture of Scholarship for Academic Librarians

Creator:: Sapon-White, Richard, King, Valery, and Christie, Anne
Abstract:: Academic library faculty require a supportive atmosphere in order to successfully engage in research and publication. At Oregon State University, the Library Faculty Association (LFA) provides avenues for peer criticism of manuscripts and presentations and for the discussion of professional issues. A survey of LFA members on their level of...

Satellite observed widespread decline in Mongolian grasslands largely due to overgrazing

Creator:: Hilker, Thomas, Natsagdorj, Enkhjargal, Waring, Richard H., Lyapustin, Alexei, and Wang, Yujie
Abstract:: The Mongolian Steppe is one of the largest remaining grassland ecosystems. Recent studies have reported widespread decline of vegetation across the steppe and about 70% of this ecosystem is now considered degraded. Among the scientific community there has been an active debate about whether the observed degradation is related to...

Drivers of radial growth and carbon isotope discrimination of bur oak (Quercus macrocarpa Michx.) across continental gradients in precipitation, vapour pressure deficit and irradiance

Creator:: Voelker, Steven L., Meinzer, Frederick C., Lachenbruch, Barbara, Brooks, J. Renee, and Guyette, Richard P.
Abstract:: Tree-ring characteristics are commonly used to reconstruct climate variables, but divergence from the assumption of a single biophysical control may reduce the accuracy of these reconstructions. Here, we present data from bur oaks (Quercus macrocarpa Michx.) sampled within and beyond the current species bioclimatic envelope to identify the primary environmental...

Genetic variation in adaptive traits and seed transfer zones for Pseudoroegneria spicata (bluebunch wheatgrass) in the northwestern United States

Creator:: St. Clair, John Bradley, Kilkenny, Francis F., Johnson, Richard C., Shaw, Nancy L., and Weaver, George
Abstract:: A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases...

Dust, volcanic ash, and the evolution of the South Pacific Gyre through the Cenozoic

Creator:: Dunlea, Ann G., Murray, Richard W., Sauvage, Justine, Spivack, Arthur J., Harris, Robert N., and D'Hondt, Steven
Abstract:: We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...

The competing effects of sulfide saturation versus degassing on the behavior of the chalcophile elements during the differentiation of hydrous melts

Creator:: Jenner, Frances E, Hauri, Erik H., Bullock, Emma S., König, Stephan, Arculus, Richard J., Mavrogenes, John A., Mikkelson, Nicole, and Goddard, Charlotte
Abstract:: There is a lack of consensus regarding the roles of sulfide saturation versus volatile degassing on the partitioning of Cu and Ag during differentiation and eruption of convergent margin magmas. Because of their oxidized character, volatile-rich magmas from the Eastern Manus Back-arc Basin (EMBB) only reach sulfide saturation following magnetite-driven...

Asymmetrical effects of mesophyll conductance on fundamental photosynthetic parameters and their relationships estimated from leaf gas exchange measurements

Creator:: Sun, Ying, Gu, Lianhong, Dickinson, Robert E., Pallardy, Stephen G., Baker, John, Cao, Yonghui, Murilo DaMatta, Fábio, Dong, Xuejun, Ellsworth, David, Van Goethem, Davina, Jensen, Anna M., Law, Beverly E., Loos, Rodolfo, Vitor Martins, Samuel C., Norby, Richard J., Warren, Jeffrey, Weston, David, and Winter, Klaus
Abstract:: Worldwide measurements of nearly 130C3 species covering all major plant functional types are analysed in conjunction with model simulations to determine the effects of mesophyll conductance (gm) on photosynthetic parameters and their relationships estimated from A/Ci curves. We find that an assumption of infinite gm results in up to 75%...

Glacial-interglacial changes in central tropical Pacific surface seawater property gradients

Creator:: Lynch-Stieglitz, Jean, Polissar, Pratigya J., Jacobel, Allison W., Hovan, Steven A., Pockalny, Robert A., Lyle, Mitchell, Murray, Richard W., Ravelo, A. Christina, Bova, Samantha C., Dunlea, Ann G., Ford, Heather L., Hertzberg, Jennifer E., Wertman, Christina A., Maloney, Ashley E., Shackford, Julia K., Wejnert, Katherine, and Xie, Ruifang C.
Abstract:: Much uncertainty exists about the state of the oceanic and atmospheric circulation in the tropical Pacific over the last glacial cycle. Studies have been hampered by the fact that sediment cores suitable for study were concentrated in the western and eastern parts of the tropical Pacific, with little information from...

The beetle tree of life reveals that Coleoptera survived end-Permian mass extinction to diversify during the Cretaceous terrestrial revolution

Creator:: Mckenna, Duane D., Wild, Alexander L., Kanda, Kojun, Bellamy, Charles L., Beutel, Rolf G., Caterino, Michael S., Farnum, Charles W., Hawks, David C., Ivie, Michael A., Jameson, Mary Liz, Leschen, Richard A. B., Marvaldi, Adriana E., McHugh, Joseph V., Newton, Alfred F., Robertson, James A., Thayer, Margaret K., Whiting, Michael F., Lawrence, John F., S´lipin´ski, Adam, Maddison, David R., and Farrell, Brian D.
Abstract:: Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...

BIOFRAG – a new database for analyzing BIOdiversity responses to forest FRAGmentation

Abstract:: Habitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among studies may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack of key statistical or methodological information. Collating primary datasets on biodiversity responses to fragmentation in...
