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...

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...

Effects of weed control on vegetation dynamics in Pacific Northwest conifer plantations

Creator:: Chen, Fen-Hui
Abstract:: Weed control in Pacific Northwest forests has been criticized for its potential impact on biodiversity. Changes were evaluated in conifer growth, diversity of vegetation in situ and of recruiting plants through different regeneration mechanisms after applying temporally-varied weed control by herbicide treatments based on the critical period concept. Conifer size...

Fertilization of 2-0 ponderosa pine seedlings in the nursery and field : morphology, physiology, and field performance

Creator:: Gleason, John F.
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Laws.) from two seed sources were grown at two nurseries. The Fremont seed source was raised at Bend and Stone Nursery; the Ochoco was grown at only the Bend Nursery. The seedlings were fertilized in late September-early October with nitrogen (N) or nitrogen plus potassium...

Frost hardiness of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings raised in three nurseries

Creator:: Schuch, Ursula K.
Abstract:: Two-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings of two seed sources raised in three nurseries in Oregon and Washington were tested for differences in frost hardiness from September 1985 to March 1986. The objective of the study was to determine whether nursery location had an influence on seedling acclimation, deacclimation...

Interaction of vegetation control and fertilization on conifer species across the Pacific Northwest

Creator:: Rose, Robin and Ketchum, J. Scott
Abstract:: An experiment evaluating three levels of vegetation competition control (no control, 1.5 m2 of vegetation control, and 3.3 m2 of vegetation control), each with two fertilization treatments (fertilization at the time of planting with complete slow-release fertilizer (Woodace® IBDU), or no fertilization), was installed at five sites. Two of these...

Effects of fertilization at the time of planting on field performance of 1+1 Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings

Creator:: Alzugaray Oswald, Patricio Javier
Abstract:: To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...

Effects of fertilization, vegetation control, and sulfur on swiss needle cast and growth of coastal Douglas-fir saplings

Creator:: Crane, Gabriel A.
Abstract:: A series of studies and replicated field sites were implemented in the Oregon Coast Range within Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) sapling plantations infected with varying levels of Swiss needle cast (SNC) caused by the fungus, Phaeocryptopus gaeumannii (Rhode) Petrak (PG). This research was conducted to understand the effects of...
