The purpose of this study was to study in some detail
host factors which influence the population dynamics of
bark beetle. The dissertation objectives were to ascertain
the applicability of utilizing osmotic pressure
values and relative turgidity values of phloem tissue as
indicators which reflect upon the physiological profile
of...
Foliage from Douglas-fir(var. glauca) seedlings grown under two light intensities was bioassayed to examine palatability to the
western spruce budworm (Choristoneura occidentalis Free.). Samples were collected in Fall, Winter and early Spring to
identify seasonal changes in host foliage, as evidenced by the response of spruce budworms. Fall collected foliage...

I developed a priori hypotheses and used logistic regression to model Greater Sandhill
Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

This paper is divided into two parts. The first part
traces (in details providing proofs and examples) the
history of the solutions of polynomial equations(of the
first, second, third, and fourth degree) by radicals from
Babylonian times (2000 B.C.) through 20th century. Also it
is shown that there is no...
The efficacy of a new broad-spectrum anthelmintic, Netobimin[subscript R]
(coded SCH 32481-Schering Corporation) was evaluated in two trials
conducted during either the spring or fall grazing seasons of 1984 in
Western Oregon using 20 cross-bred yearling beef heifers and 30
cross-bred spring lambs, respectively. Percent efficacies were
determined in both...
