Life history and environmental influences on avian incubation and parental care in songbirds

Creator:: Austin-Bythell, Suzanne H.
Abstract:: Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions. Incubation, in particular, is of interest because adults must provide an environment suitable for embryonic development through nest-building and contact-incubation. We evaluated how adult incubation constancy and nest visitation...

Biogeographic and experimental evidence for local scale dispersal limitation in central Panamanian forest birds

Creator:: Moore, Randall Phillips, 1965-
Abstract:: I examined the avian biogeography of the islands of Lago Gatun, Panama, in an effort to better understand the effects of forest fragmentation in this biodiverse region, and specifically to understand the importance of fragment isolation and the mechanism behind its effects on tropical bird distribution. I combined exhaustive surveys...

Pulmonary function of male cigarette smokers compared with lifetime noncigarette smokers

Creator:: Barr, Robert Douglas
Abstract:: The pulmonary function scores of 250 male cigarette smokers were compared with 406 lifetime nonsmokers. A Stead-Wells spirometer was used to obtain forced vital capacity, forced expiratory flow, forced mid-expiratory flow, and forced expiratory volume. All individuals included in the sample were between. the ages of 20 and 49 years....

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

The antibody response of juvenile coho salmon (Oncorhynchus kisutch) to Aeromonas salmonicida, the causative agent of furunculosis

Creator:: Paterson, William Douglas
Abstract:: This research was initiated to investigate the effects of various parameters on the immune response of juvenile coho salmon to Aeromonas salmonicida. The antibody response and development of protective immunity in juvenile coho salmon were followed after a single intraperitoneal injection of formalin killed A. salmonicida cells emulsified in Freund's...

Geographic and seasonal variation in photosynthetic efficiency and capacity of Rocky Mountain Douglas-fir, Pseudotsuga menziesii var. glauca

Creator:: Pope, Walter William
Abstract:: Net photosynthesis was measured for photosynthetic light efficiency and capacity on two-year-old plants from eight different seed sources in three measurement periods. The measurement periods corresponded to the physiological periods 1) prior to bud swelling, 2) after needle elongation, and 3) predormancy. Measurement period differences in both photosynthetic efficiency and...

The effect of osmotic moisture stress during germination on Douglas-fir (Pseudotsuga menziesii)

Creator:: Stewart, Ronald E
Abstract:: Commercially collected Douglas-fir seed from a moist coastal ecotype (LaPush, Washington) and a dry inland ecotype (Kaibab National Forest, Arizona) were subjected to osmotic stresses ranging from 0 to -8 atmospheres using Carbowax polyethylene glycol 6000 during imbibition and germination. To determine the effect of osmotic stress on the initiation...
