Plant-Arthropod Interactions in Acanthostrobus edenensis (Cupressaceae), a New Conifer from the Upper Cretaceous of Vancouver Island, British Columbia

Creator:: Klymiuk, Ashley A, Stockey, Ruth A., and Rothwell, Gar W.
Abstract:: Premise of research. A new, morphologically distinct, anatomically preserved conifer assignable to the basal Cupressaceae, which was subject to arthropod infestation during life, has been discovered within a marine carbonate concretion from the Coniacian (Late Cretaceous) Eden Main locality of Vancouver Island, British Columbia. Methods. Specimens were studied from anatomical...

Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Grassland Arthropods Are Controlled by Direct and Indirect Interactions with Cattle but Are Largely Unaffected by Plant Provenance

Creator:: Farrell, Kelly Anne, Harpole, W. Stanley, Stein, Claudia, Suding, Katharine N., and Borer, Elizabeth T.
Abstract:: Cattle grazing and invasion by non-native plant species are globally-ubiquitous changes occurring to plant communities that are likely to reverberate through whole food webs. We used a manipulative field experiment to quantify how arthropod community structure differed in native and non-native California grassland communities in the presence and absence of...

Vertebrates, arthropods, and invasive plants : an investigation of the top-down and bottom-up interactions of multiple herbivore guilds in a grassland system

Creator:: Farrell, Kelly Anne
Abstract:: Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has...

Investigating Protein-lipid-membrane Interactions in Plant Cells using Bimolecular Fluorescence Complementation

Creator:: Tao, Kai
Abstract:: The overall focus of this thesis is on the distribution of specific lipids and membrane proteins of the external and internal membranes of plant cells, in the context of the roles that those lipids and proteins may play in microbe-plant interactions. The work includes the development of several new tools,...

Arthropod communities on understory plants in thinned and unthinned Douglas-fir forests in the Oregon Coast Range

Creator:: Doolittle, Alyssa M.
Abstract:: This study assessed the effects of thinning on arthropod communities on understory plants in the Central Oregon Coast Range. Arthropods were sampled from five understory plants in five pairs of thinned and unthinned, young (50-80 yrs), managed Douglas-fir stands, from late May to mid-July of 1998. Vine maple (Acer circinatum),...

Is fire exclusion in mountain big sagebrush communities prudent? Soil nutrient, plant diversity and arthropod response to burning

Creator:: Davies, Kirk W., Bates, Jonathan D., Boyd, Chad S., and Nafus, Aleta M.
Abstract:: Fire has largely been excluded from many mountain big sagebrush communities. Managers are reluctant to reintroduce fire, especially in communities without significant conifer encroachment, because of the decline in sagebrush-associated wildlife. Given this management direction, a better understanding of fire exclusion and burning effects is needed. We compared burned to...

Canopy arthropod assemblages in four overstory and three understory plant species in a mixed-conifer old-growth forest in California

Creator:: Schowalter, Timothy D. and Zhang, Yanli
Abstract:: We compared canopy arthropod assemblages among overstory conifer and understory angiosperm species at Teakettle Experimental Forest in the Sierra Nevada in California during 1998–2000. Arthropods were sampled from upper, middle, and lower crown levels of one overstory tree of each of the four dominant conifer species (Jeffrey pine, sugar pine,...
