A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

Assessment of factors regulating growth hormone binding in pigs

Creator:: Mullins, Tracy M.
Abstract:: These studies were conducted to examine the influence of several variables on the growth hormone binding protein (GHBP) in serum of pigs. Continuous long term porcine somatotropin (pST) injections (daily for 6-7 wk) increased GHBP activity (p < .05). However, periodic short term pST injections (daily, every second d or...

Non-linear nitrogen dynamics and calcium depletion along a temperate forest soil nitrogen gradient

Creator:: Sinkhorn, Emily R.
Abstract:: Understanding how N availability influences base cation stores is critical for long-term ecosystem sustainability. Indices of nitrogen (N) availability and the distribution of nutrients in plant biomass, soil, and soil water were examined across ten young, unpolluted Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range spanning a three-fold soil...

Anthocyanin pigment, nonvolatile acid and sugar composition of blackberries

Creator:: Fan-Chiang, Ho-ju
Abstract:: The pigments of blackberry fruit were investigated by analytical and preparative high performance liquid chromatography (HPLC) to characterize anthocyanin patterns in commercially important blackberry (Rubus eubatus) cultivars and selections. Five anthocyanin pigments were detected in Evergreen blackberry and they were identified as cyanidin-3-glucoside, cyanidin-3-rutinoside, pentosecyanidin derivative and two acylated cyanidin...

Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

Creator:: Sierra, Carlos Alberto
Abstract:: Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...

Impact of seasonal variation and growing environment on blackberry aroma

Creator:: Wang, Yuanyuan
Abstract:: Blackberries have been enjoyed for their delicious flavor and high nutritional value for hundreds of years. In North America, blackberries were cultivated since 1850-1860. Blackberries have their characteristic and unique aromas depending on the cultivar and growing conditions. The objective of this study was to evaluate the impact of seasonal...

A comparison of the value of forest plans developed under three levels of detail regarding management intentions

Creator:: Hirte, Sarah Rebecca
Abstract:: In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...
