Applications of several methods of coherent nonlinear Raman Spectroscopy have been made in this thesis research. The theory and potential of one of these, Photoacoustic Raman Spectroscopy (PARS), is discussed in chapter two. Experimental results are presented which illustrate the sensitivity of this method and establish sampling conditions for maximum...
Rates of predation on artificial nests and nests of pen-reared
ring-necked pheasants (Phasianus colchicus), released in spring, were
compared between strip and block habitats at different densities of
nests. Nests in strips had rates of predation 4-7 times greater than
nests in blocks, regardless of nest density. Differences between
successful...
This report summarizes the results of our bay clam studies in 1985. Activities summarized include monitoring of the recreational and commercial clam fisheries, hatchery stock enhancement studies, natural recruitment studies, and miscellaneous other projects.

The Port of Coos Bay is considering expanding their marina facilities in Charleston. Several sites are being considered; one to the north of the present boat basin and one to the south (Figure 1). The southern proposal is for an area that historically has supported an important recreational clam fishery....
This document summarizes investigations of the effluent discharge from a nearby pulp mill into Coos Bay. It discusses discovery of the discharge, but focuses on its effects on gaper clams in the bay.
It is possible that the large fluctuations In annual Dungeness crab landings are caused by displacement of crab larvae by currents. We studied the effects of various environmental factors on crab larvae survival and behavior. Tests were conducted on cultured zoeae and megalopae and on wild megalopae.
Our studies showed...
"This report covers studies conducted on Dungeness crab larvae from July 1, 1969, through June 19, 1970. Principal objectives were to determine the following: (1) the effects of crab larval concentration on growth and survival; (2) the effects of light intensity on the swimming behavior of crab larvae; (3) the...
"Objectives during the July 1, 1968, to June 30. 1969, project period were to determine the following: 1. The effects of diet concentration on survival and growth. 2. The effects of crab larval concentration on survival. 3. The effects of diet concentration on cannibalism. 4. The effects of light intensity...
Medusahead (Taeniatherum asperum Nevski), a winter annual native to the Mediterranean region of Eurasia, has infested several million acres of rangeland in the northwestern United States. It has been estimated carrying capacity for domestic livestock on infested ranges has been reduced 75 percent.
The review is a condensed summarization of...
