Seamount morphology in the Bowie and Cobb hot spot trails, Gulf of Alaska

Creator:: Chaytor, Jason D., Keller, Randall A., Duncan, Robert A., and Dziak, Robert P.
Abstract:: Full-coverage multibeam bathymetric mapping of twelve seamounts in the Gulf of Alaska reveals that they are characterized by flat-topped summits (rarely with summit craters) and by terraced, or step-bench, flanks. These summit plateaus contain relict volcanic features (e.g., flow levees, late-stage cones, and collapse craters) and as such must have...

Behavioral adaptations and the minimization of reproductive costs in the male red-sided garter snake, Thamnophis sirtalis parietalis.

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

Conservation biology of Perideridia erythrorhiza (Apiaceae) : experimental reintroduction and life history

Creator:: Roberts, Kimberly A.
Abstract:: An experimental reintroduction was performed to determine the best method to create new populations of the tuberous species Perideridia erythrorhiza, a rare vascular plant endemic to southern Oregon. Only a handful of sites are currently present, and many of these are subject to other land uses such as urban development...

Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

Creator:: Esler, Daniel
Abstract:: The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

Effects of vegetation control, stock size, fertilization, and soil moisture on the shoot and root development of Douglas-fir seedlings

Creator:: Burney, Owen T.
Abstract:: The overall purpose of this study was to examine the root and shoot development of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings at two distinct time periods in seedling establishment (after I and 3 growing seasons) in response to fertilizer, stock size, vegetation control, and soil moisture treatments. Two separate experiments...

Molecular characterization of criniviruses and ilarviruses infecting strawberry

Creator:: Tzanetakis, Ioannis E.
Abstract:: Pallidosis is a disease of strawberry identified in 1957 with an unknown etiology. Two previously uncharacterized viruses in strawberry, Strawberry pallidosis associated virus (SPaV) and Beet pseudo-yellows virus (BPYV), have been found associated with disease symptoms. The complete nucleotide sequence of both viruses was determined and molecular detection protocols developed....

Effects of fertilization, vegetation control, and sulfur on swiss needle cast and growth of coastal Douglas-fir saplings

Creator:: Crane, Gabriel A.
Abstract:: A series of studies and replicated field sites were implemented in the Oregon Coast Range within Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) sapling plantations infected with varying levels of Swiss needle cast (SNC) caused by the fungus, Phaeocryptopus gaeumannii (Rhode) Petrak (PG). This research was conducted to understand the effects of...
