Seed quality and plant establishment studies of seashore paspalum (Paspalum vaginatum Sw.)

Creator:: Baker, Stanley D.
Abstract:: Seashore paspalum (Paspalum vaginatum Sw.) is an important warm-season perennial turfgrass, known for its tolerance to salinity. Turfgrass is used for homes, municipalities, sod farms, resorts, and sports fields. Seashore paspalum has historically been planted in sub-tropical and tropical climates because of its heat tolerance. Seashore paspalum could become an...

Biological soil crusts in forested ecosystems of southern Oregon : presence, abundance and distribution across climate gradients

Creator:: Olarra, Jennifer A.
Abstract:: In arid and semi-arid deserts, soils are commonly covered with biological soil crusts. The study of arid biocrusts and their ecological function has become increasingly common in the literature over the last several decades. Interestingly, no mention is made of biological soil crusts in forested ecosystems, raising the question as...

Multiscale habitat electivity and movement patterns by adult spring chinook salmon in seven river basins of northeast Oregon

Creator:: Price, David M.
Abstract:: I examined habitat electivity and movement patterns of adult spring chinook salmon at microhabitat and channel unit spatial scales, and seasonal to annual temporal scales in seven streams in the Grande Ronde, John Day, and Imnaha basins. The objective was to compare habitat use and availability among streams, channel units,...

Stem sapwood water transport and storage strategies in three conifers from contrasting climates

Creator:: Barnard, David M.
Abstract:: The state of Oregon has two distinct climate types bisected by the crest of the Cascade Mountain range. The western side of the Cascades experiences high levels of precipitation and mild temperatures due to the maritime influence of the Pacific Ocean, while the eastern side lies in the rain shadow...

Statistical analysis of climatological data to characterize erosion potential : 6. joint precipitation and freezing events in eastern Oregon/Washington

Creator:: Istok, Jonathan D., Brown, Barbara G., Boersma, Larry, Katz, Richard W., and Murphy, Allan H.
Abstract:: When precipitation falls on frozen soil, serious soil loss can occur. In order to assign realistic probabilities to the occurrence of this condition for use in predicting erosion rates over long time periods, a technique for combining characteristics of precipitation and air temperature records is applied to hourly wet season...

Statistical analysis of climatological data to characterize erosion potential : 4. freezing events in eastern Oregon/Washington

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., Murphy, Allan H., and Boersma, Larry
Abstract:: The occurrence of frozen soil has a major effect on runoff and soil loss in the Pacific Northwest. Hence, information regarding the probabilities of occurrence of periods during which the soil may be frozen is necessary in order to adequately forecast long-term erosion rates for this region. In order to...

Statistical analysis of climatological data to characterize erosion potential : 2. precipitation in eastern Oregon/Washington

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., and Murphy, Allan H.
Abstract:: Periods of precipitation with certain combinations of characteristics (e.g., high intensity rainfall on saturated soil) can lead to appreciable soil loss in the Pacific Northwest. In order to assign realistic probabilities to the occurrence of these periods for use in predicting long-term erosion rates, a soil erosion-specific definition of a...

Abstract:: When precipitation falls on frozen soil, serious soil loss can occur. In order to assign realistic probabilities to the occurrence of this condition for use in predicting erosion rates over long time periods, a technique for combining characteristics of precipitation and air temperature records is applied to more than 31...
