Foraging ecology of pollinators in the early stages of secondary succession in the western hemlock (Tsuga heteropohylla (Raf.) Sarg.) zone of the Oregon Coast Range

Creator:: Burikam, Intawat
Abstract:: The early stages of secondary succession of the McDonald and Paul Dunn State Forests, Corvallis, Oregon, were grouped into three stages; herb, herb-shrub, and shrub, based on vegetation types. Flowers of herbaceous species and residual shrubs dominated in the early years after clear-cutting. Woody plants became increasing abundant in the...

Agronomic performance of six winter wheat dwarfing sources when crossed to isogenic lines for Norin 10 Rht loci

Creator:: Pedretti, Ricardo
Abstract:: Six genetically diverse dwarfing sources of winter wheat were compared to four isogenic lines for the height reducing genes Rht₁ and Rht₂. Parents and generations through the F₃ including backcrosses to the respective parents were analyzed. Seedling response to gibberellic acid and tests for allelism for plant height were employed...

A New Record of Planktic Foraminifera Community Response to Marine Heatwaves in the Northeast Pacific

Creator:: M. Kelsey Lane
Abstract:: Marine heat waves are forecasted to increase in frequency and intensity under future climate scenarios, but little is known about the impact of these events on the one of the most commonly used proxies of ocean temperature - foraminiferal assemblages. This research explores the planktic foraminifera community along the Newport...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

Modifying selected factors to classify levels of resistance or tolerance in wheat to Septoria Tritici Blotch

Creator:: Re, Jose Vicente
Abstract:: Influence of abiotic and biotic factors were examined in selected winter wheats previously identified as representing a range of responses to septoria infection. In the greenhouse two and three inoculations identified resistance when disease severity was assessed either for the top four leaves or the flag leaf respectively. Kernel number...

Isozymic and cytological studies on populations of the introduced bee species, Megachile (Eutricharaea) rotundata and M. (Eutricharaea) apicalis

Creator:: Chen, Xiaoshe
Abstract:: Thirteen New World populations of Megachile rotundata and M. apicalis and two Old World populations of M. rotundata were analyzed at 23 enzyme loci using cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were also examined in these populations. The principal findings are (1) No differences were found in...
