Experiments were performed to determine whether a direct
correlation exists between the growth rates of tall and dwarf peas
grown either in the light or in the dark and endogenous gibberellin
(GA) content. Three separate but related experimental approaches
were utilized: (1) the determination of possible qualitative and /or
quantitative...
Studies were conducted during late winter and spring of 1970 to
establish the extent of spawning of Pacific herring (Clupea harengus
pallasi Valenciennes) in the Yaquina estuary, and to define the degree
of egg mortality on certain substrates. Routine surveillance of the
north shore of the estuary provided information on...
A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...
Habitat fragmentation has been widely studied in the biological literature and
is considered a primary threat to biodiversity. However, there has been little research
on land-use policies to reduce fragmentation. This dissertation focuses on two major
research issues related to fragmentation policies. First, I develop an analytical model
to analyze...
Bembidion (Sloanephila) tahitiense, sp. nov., is described from Mont Mauru, an isolated massif of Tahiti Nui volcano. Based upon evidence from seven genes (four nuclear protein-coding, one mitochondrial protein-coding, two nuclear ribosomal), its sister group is the Australian B. jacksoniense Guérin-Méneville, with which it shares a synapomorphic spur on the...

The physico-chemical reactions of ammonia in soils and clays have many practical and theoretical implications. On the one hand, large quantities of anhydrous ammonia are used annually in agriculture for fertilizer; the dry gas is applied directly to the soil by simply injecting it below the ground surface. On the...
