Habitat use and selection by sage grouse broods in southeastern Oregon

Creator:: Drut, Martin S.
Abstract:: In Oregon, sage grouse (Centrocercus urophasianus) were common in the eastern portion of the state. Since 1940 populations declined because of decreased productivity. The western subspecies (C. u. phaios) was listed as a candidate for threatened and endangered status in 1985 because of declines in Oregon and Washington and extirpation...

Post mortem interval and decomposition rates : biological observations and mathematical analysis

Creator:: England, David B.
Abstract:: Entomological evidence can be used for estimating post mortem interval (PMI). Decomposition studies have been conducted throughout the world and these studies have demonstrated that insect succession generally follows a similar pattern at a taxonomic level, specifically family, but varies at the genus and species levels with respect to geographic...

Habitat alteration and human disturbance : their impact on cougar habitat utilization in southwest Oregon

Creator:: Gagliuso, Robert A.
Abstract:: Eight cougars were radio-collared and monitored during 1985 - 1987. Home range size, determined by minimum convex polygons, averaged 153.1 km2 for females, 543.5 km2 for males. Core home range size, determined by harmonic mean analysis, averaged 21.7 km2 for females, 17.9 km2 for males. Home ranges of males and...

Variation in female reproductive success in amphibians

Creator:: Dyal, Leslie A.
Abstract:: My dissertation focuses on the factors that influence variation in female reproductive success in plethodontid salamanders and in toads. Variation in reproductive success fuels evolutionary change. Although, females often have been overlooked in studies of reproductive success due to perceived lower levels of variation when compared to variation in male...

The asymmetric binding of Actinomycin D to DNA hexamers

Creator:: Ivancic, Monika
Abstract:: The solution structure determination of DNA molecules has been an important part of structural biology. NMR solution structures are a complement to structures solved via X-ray crystallography; the two methods are the only ways of obtaining three dimensional coordinates of macromolecules. Because of the nature of the molecule, the solution...

Complex architecture of a closterovirus virion

Creator:: Napuli, Alberto J.
Abstract:: In this investigation we examined the molecular architecture and functions associated with the virion components of the Beet yellows virus (BYV), family Closteroviridae. The BYV virions are filamentous particles composed of two coat proteins, the major coat protein (CP), which encapsidates the majority of the genome, and the minor coat...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Bioactive natural products from marine algae

Creator:: Tan, Lik Tong
Abstract:: This thesis is an account of my investigation on the natural products deriving from various marine algae and has resulted in the discovery of thirteen novel bioactive metabolites. Isolation and characterization of these unique molecules were carried out using different chromatographic techniques and by careful analyses of 1D and 2D...
