Global atmospheric pollution from chlorofluorocarbons has the
potential of causing significant reductions in the concentrations of
stratospheric ozone. If the production of chlorofluorocarbons were
to continue into the future at the rate prevalent in 1977, the
steady state reduction in total global ozone could be between five
percent to ten...
The breeding biology and early life history of the Tufted Puffin (Fratercula cirrhata) were studied for two years on Goat Island, Curry County, Oregon. Artificial nest boxes were used to minimize disturbance and provide easy access to puffin eggs and chicks. Utilization of these boxes was 47.5% and 57.5% in...
Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...
A complete solution, exact to second-order, for wave motion
forced by a hinged-wavemaker of variable-draft is presented. A
solution for a piston type wavemaker is also obtained as a special
case of a hinged-wavemaker with negative infinite draft. The
existing Stokes inviscid theories for mass transport is extended to
include...
I. THE EFFECT OF FEEDING PROGRAMS ON REPRODUCTIVE TRAITS AND
SELECTED BLOOD CHEMISTRIES OF CAGED BROILER BREEDER MALES:
1. FEED RESTRICTION LEVELS:
The effects of five different feeding levels (136, 125, 113,
102, and 91 g/male/day of a 13.1% crude protein (CP), 3167 kcal ME/kg
feed) on the reproductive traits...

Sheep live weights, herbage standing crop, and herbage quality
are presented from a three-year grazing management study comparing
set stocking, four-paddock rotational grazing, and four-paddock
forward rotational grazing systems. In both rotational grazing and
forward rotational grazing systems, sheep were sequentially moved
from one paddock to the next every 5...
From July, 1982 to August, 1983 I had the privilege of serving an internship
as an oceanographer at the National Marine Fisheries Service Beaufort
Laboratory. During the period of my appointment I assisted in a preliminary
assessment of the potential fishery impacts of ocean thermal energy conversion
(OTEC) power plants....
