Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:: Gernandt, David S.
Abstract:: The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...

The effects of nitrogen manipulations and hydrology on the establishment and competitive abilities of wetland prairie plant species (western Oregon)

Creator:: Davis, Kimberly J.
Abstract:: Many studies suggest that weedy plant species are most successful when soil nitrogen in abundant. Consequently, I used soil nitrogen manipulations to determine if altering nitrogen would affect the establishment of both weedy and native plant species in a western Oregon wetland prairie. In two studies, we added carbon amendments...

Responses of algal populations to parasitism by Aphelidium chlorococcarum and chytrids in an Oregon sewage lagoon

Creator:: Woods, Wendy W.
Abstract:: The abundance of algal species and their parasites was monitored weekly for two years in a sewage lagoon at the Corvallis Airport, Oregon. During the cooler months, Euglena species were dominant followed by a Chlamydomonas assemblage in the spring and a predominantly Scenedesmus assemblage in the summer and fall. Parasites...

Photoacclimation in Marine Phytoplankton Under Various Light and Nutrient Regimes and the Resulting Effect on Photosynthetic Electron Flow and Chlorophyll Fluorescence Transients

Creator:: Brown, Matthew B.
Abstract:: Photoacclimation is the process by which plants and phytoplankton adjust the concentration and composition of their photosynthetic machinery (i.e. their photoacclimation state) in response to changes in their light or nutrient environment. The purpose of photoacclimation is to balance the rate at which light energy is absorbed with the energetic...

Evolutionary relationships and an investigation of sympatric speciation within Limnanthaceae

Creator:: Meyers, Stephen C.
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

The distribution of intertidal diatoms associated with the sediments of Yaquina Estuary, Oregon

Creator:: Amspoker, Michael C.
Abstract:: Sediment samples were collected from eight sampling sites along the Yaquina Estuary, Oregon from Yaquina Bay to Elk City near the head of the estuary. Samples were collected in November 1973, February 1974, May 1974 and August 1974 from two or three intertidal levels depending on the magnitude of the...

Resistance mechanisms of Port-Orford-cedar to Phytophthora lateralis

Creator:: Oh, Eunsung
Abstract:: Breeding Port-Orford-cedar for resistance to Phytophthora lateralis, a causal agent of root disease, begins by screening, through artificial inoculation, phenotypically resistant trees selected from natural stands. The successful program selected tolerant or resistant POC parent trees for the purpose of disease management. Candidate resistant POCs were used in my dissertation...
