This thesis reports the results of a study on the influence of biologically
stabilized kraft mill effluent (SKME) on the food relations and
production of juvenile chinook salmon, Oncorhynchus tschawytscha
(Walbaum), in laboratory streams. Experiments were conducted at
the Oak Creek Fisheries Research Laboratory, Oregon State University,
during 1967 and...
The littoral zones of seven reservoirs in the southern Willamette Valley of Oregon were sampled with a boat electroshocker during the summer months of 1995 and 1996. Shoreline substrates were inventoried before sampling sites were randomly selected. Sampling sites consisted of 9 of 12 possible habitat types including four substrate...
Seasonally, in 1998 and 1999, I examined spatial and temporal variation in fish assemblages of agricultural, forested, and acid mine drainage tributaries within the Wayne National Forest (WNF) in southern Ohio. Land use and natural disturbance explained patterns in stream fish assemblages. Creek chub and green sunfish were present in...
The wind field measured during Project JASIN 1972, a joint
British-American venture during September 1972, was analyzed.
These measurements were done, with equipment manufactured by
Ivar Aanderaa of Bergen, Norway, on large, anchored toroid buoys.
The results of the analysis of the wind field, which included
divergence and vorticity estimates...
Rats exposed to one or two doses of 60 mg mirex/kg
by gavage exhibited hypertrophied livers and various
degrees of hepatobiliary dysfunction. Although single
dosed animals demonstrated elevated whole liver bile flow
after 96 hours, the single dose was insufficient to
significantly inhibit whole liver hepatobiliary
performance as measured by...
The purpose of this study was to describe the perceptions of the first year experience of teaching secondary agriculture and to explore the relationships between these perceptions, the characteristics of beginning agriculture teachers, and the types of support provided to beginning teachers. An additional focus of the study was to...
