A study of the vocal behavior of the American robin

Creator:: Benson, Jane Rae
Abstract:: To gain a better foothold on the communication system of the avifauna, calls and songs of the American Robin (Turdus migratorius) were recorded and analyzed using the sound spectrograph. Ten different calls were recognized as follows: three alarm calls, an excitement call, challenge call, contact call, two flight calls and...

The evolutionary stability of partial migration

Creator:: Ohms, Haley A.
Abstract:: Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

American robin : Turdus migratorius

Creator:: Oregon State University. Extension Service, Grunberg, Mindy, and Sells, Sarah
Abstract:: The American robin, Turdus migratorius, is one of the best known birds in North America. Robins are the largest member of the thrush family. Thrushes have large eyes, long legs, and strong bodies. Robins are known for their habit of feeding on earthworms in lawns and for the song they...

Effects of gluten composition and molecular weight distribution on the noodle making potential of hard white wheats

Creator:: Ong, Yee-Ling
Abstract:: A set of flour samples with protein content ranging from 9.7 - 13.3 % was used for this study to evaluate the effectiveness of HMW-GS, SEHPLC and mixograph characteristics as screening tools for noodle texture. The sample set had a large variation in HMW-GS composition with Payne score ranging from...

The combined effects of vegetation control and seedling size class on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedling productivity on a site in Oregon

Creator:: Lefebvre, Robert F.
Abstract:: Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

Influence of root architectural development on Douglas-fir seedling morphology and physiology

Creator:: Jacobs, Douglass Frederick
Abstract:: A series of experiments were established to gain a better understanding of the extent to which Douglas-fir seeding root architecture may be manipulated and subsequent influences on seedling morphological and physiological development. The incorporation of amendments into nursery soils changed root architecture to some degree, but did not produce large...

Psychedelics and Entheogens : Implications of Administration in Medical and Non-Medical Contexts

Creator:: Kirk, Hannah R.
Abstract:: Psychedelics and entheogens began as religious sacraments. They were apotheosized for their mind-expanding powers and were thought to open realms to the world of the Gods. It was not until the first psychedelic compound was discovered in a laboratory setting a mere hundred years ago that they entered into formal...
