Growth of a sea urchin, Allocentrotus fragilis, at different depths off the Oregon coast

Creator:: Sumich, James L.
Abstract:: Allocentrotus fragilis (Jackson) was obtained from six stations at depths of 100 to 1260 m on the continental shelf and upper slope off Newport, Oregon. Ages and growth rates of A. fragilis were determined by two methods: 1) A procedure was developed to make growth zones of the skeletal test...

Latitudinal distribution, calf growth and metabolism, and reproductive energetics of gray whales, Eschrichtius robustus

Creator:: Sumich, James L.
Abstract:: Gray whales accomplish an annual migration which spans as much as 50° of latitude in the northeast Pacific Ocean. This migration links their summer high latitude feeding grounds with winter calving and breeding areas. The purpose of this study was to determine how adult females apportion their stored lipid reserves...

The Future of Aquaculture and Its Role in the Global Food System

Creator:: Anderson, James L.
Abstract:: There are only three fundamental sources for increasing seafood supply: 1) better management and utilization of wild fish stocks, 2) aquaculture and 3) aquaculture-enhanced ‘wild’ fisheries. However, nearly all of the significant growth in global seafood harvest and international trade over the past three decades has, and in the future...

Relationships between air quality and thermal structure of the lower atmosphere at Salem, Oregon

Creator:: McElroy, James L.
Abstract:: The examination in some detail of the relationships between air quality and the thermal structure of the lowest layers of the atmosphere constituted the primary objective of this thesis. Data for the study were assembled during April-June 1965 at the U.S. Weather Bureau Station, McNary Field, Salem, Oregon. The measures...

An analytical model for fatigue crack propagation

Creator:: Anderson, James L.
Abstract:: Beginning with the basic equations from the theory of elasticity and employing a model of crack propagation based on the concept of a constant plastic energy absorption per unti of crack extension, the commonly accepted power law of fatigue crack propagation was derived. This derivation uses an extension of the...

Tillering, lodging, dry matter partitioning, and seed yield in ryegrass (Lolium spp.) as affected by the plant growth regulator paclobutrazol

Creator:: Hunter, James L.
Abstract:: Seed yield in ryegrass (Lolium spp.) is the product of the number of fertile tillers per unit area and seed weight per spike at maturity. These components of yield develop through a series of growth stages beginning with tiller bud initiation and finishing with seed filling. Environmental conditions during plant...

The laplace approximation and inference in generalized linear models with two or more random effects

Creator:: Pratt, James L.
Abstract:: This thesis proposes an approximate maximum likelihood estimator and likelihood ratio test for parameters in a generalized linear model when two or more random effects are present. Substantial progress in parameter estimation for such models has been made with methods involving generalized least squares based on the approximate marginal mean...
