ROLE OF THE ASCIGEROUS STATE IN THE EPIDEMIOLOGY OF EYESPOT IN WHEAT
Eyespot is a chronic disease of winter wheat, caused by Oculimacula yallundae (OY) and O. acuformis (OA) that results in premature ripening of grain, lodging, and reduced grain yield. Discovery of the Oculimacula spp. ...
Landscape-based Null Models for Archaeological Inference
How do we, as humans and as scientists, learn about the world around us? In this dissertation, I explore how models--epistemological tools that connect theory and reality--not only structure scientific inquiry (including ...
Essays on Imperfect Competition and International Trade
This dissertation consists of three chapters based on product differentiation and increasing returns to scale. Chapter 1 studies a static monopolistic competition model with social indifference curves over a group of ...
Pollinator-mediated gene flow in and among fields of alfalfa produced for seed
Cross-pollination by bees is necessary for commercial alfalfa seed production. To maintain varietal purity in alfalfa, seed producers adhere to spatial isolation standards to minimize or prevent bee flight and subsequent ...

GENETIC MECHANISMS OF RESISTANCE TO FUSARIUM ROOT ROT IN PEA (PISUM SATIVUM L.)
Pea (Pisum sativum L.) is an important cool season food legume grown worldwide. High protein and nutritional value, nitrogen fixation, lower water usage and easy growth are some of the benefits of pea production. Despite ...
RECTAL MICROBIOTA DYNAMICS IN PRE-WEANED DAIRY CALVES DEPENDING ON COLOSTRUM INTAKE, PRESENCE OF DIARRHEA AND ANTIBIOTIC TREATMENT
The mammalian intestine microbial community carries out many functions contributing to host's defense from infectious diseases, nutrition, growth, immunodevelopment and immunomodulation. Several factors such as diet, age, ...
Characterization of glyphosate-resistant mechanism(s) in spring wheat (Triticum aestivum L.) induced through mutagenesis
Wheat susceptibility to glyphosate, a non-selective herbicide targeting the EPSPS enzyme, encouraged the development of glyphosate-resistant (GR) spring wheat through mutation breeding using ethyl methanesulfonate (EMS) ...
