The purpose of this study was to describe the leadership development process
of former student leaders at Snow College. More specifically, the study focused on
understanding how, when, and where leadership development took place in their
"lived experience" within the student government at Snow College (Van Manen,
1998). Examining the...
Biophysical, socioeconomic and geopolitical pressures from population growth and economic development are leading to an increase in tensions regarding the sharing of water within transboundary basins. Transboundary basins are surface rivers and groundwater resources that are shared among sovereign nations and autonomous regions. This dissertation focuses on surface water in...

Verticicladiella wageneri Kendrick is a vascular wilt
pathogen of conifers, causing a black staining of
colonized sapwood of roots and lower stem. In Douglas-fir,
V. wageneri is intimately associated with insects.
Hylastes nigrinus, Pissodes fasciatus, and Steremnuis
carinatus are commonly associated with diseased hosts,
carry inoculum of V. wageneri in...
Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....
When trees from 16 populations of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco. var. menziesii) were grown at ten geographically diverse locations for seven years, those from a Vancouver Island source were among the top three for height growth on nine of the ten plantations (Rowe and Ching, 1974). In contrast, growth...
Shorebirds display great variation in mating systems and breed in dynamic environments that are increasingly subject to human threats worldwide. In order to adequately assess productivity and demography of shorebird populations, it is important to understand factors that influence patterns of parental care and reproductive success. The Black Oystercatcher (Haematopus...
Fishery biologists and watershed management specialists have recently begun to investigate the pollutional threat posed by organic debris left in or near the forest watercourses. Oxygen content in some streams has fallen below the limits required for fish survival. The biochemical oxygen demand exerted by the debris and the reaeration...
Wild turkey (Meleagris gallopavo) ecology has been examined within its native range, but knowledge of extralimital populations of Rio Grande wild turkeys (M. g. intermedia) is lacking. I investigated habitat use, characteristics of activity sites, home
ranges and movements, productivity, and survival of Rio Grande turkey hens from 1989
through...
In order to produce infectious virus progeny, vaccinia virus (VV)
undergoes morphogenic proteolysis to regulate the structural rearrangements of
virus particles. Several of the major structural precursor proteins of VV are
cleaved at a conserved Ala-Gly-X (where X is any amino acid) motif by the VV
I7L core protein proteinase...
