Biology Faculty Publications and Presentations
Premise of research. Shared ancestry and convergent/parallel evolution are the two primary causes of morphologically similar species occurring in similar climatic niches. Alpine habitats harbor a unique biodiversity that is often characterized by many convergences in life-forms, such as cushion and rosulate habits. Three species of Lomatium (L. greenmanii, L. erythrocarpum, and L. oreganum) are high-alpine specialists endemic to the Wallowa and Elkhorn Mountains of northeastern Oregon. Earlier studies suggested that two of these species might be sister taxa, but because of the prevalence of convergence in alpine habitats and recent studies that have highlighted …
Sensory Stressors Impact Species Responses Across Local And Continental Scales, Ashley A. Wilson
Sensory Stressors Impact Species Responses Across Local And Continental Scales, Ashley A. Wilson
Master's Theses
Pervasive growth in industrialization and advances in technology now exposes much of the world to anthropogenic night light and noise (ANLN), which pose a global environmental challenge in terrestrial environments. An estimated one-tenth of the planet’s land area experiences artificial light at night — and that rises to 23% if skyglow is included. Moreover, anthropogenic noise is associated with urban development and transportation networks, as the ecological impact of roads alone is estimated to affect one-fifth of the total land cover of the United States and is increasing in space and intensity. Existing research involving impacts of light or noise …

The use of black soldier fly frass fertilizer (BSFFF) is being promoted globally. However, information on nitrogen (N) fertilizer equivalence (NFE) value and synchrony of N mineralization for crop production remains largely unknown. Comparative studies between BSFFF and commercial organic fertilizer (SAFI) were undertaken under field conditions to determine synchrony of N release for maize uptake. The BSFFF, SAFI, and urea fertilizers were applied at the rates of 0, 30, 60, and 100 kg N ha−1. The yield data from urea treated plots were used to determine the NFE of both organic inputs. Results showed that maize from BSFFF treated …

Poultry Science Faculty Publications and Presentations
Salmonella Enteritidis (SE) is a facultative intracellular pathogen that colonizes the chicken gut leading to contamination of carcasses during processing. A reduction in intestinal colonization by SE could result in reduced carcass contamination thereby reducing the risk of illnesses in humans. Short chain fatty acids such as butyrate are microbial metabolites produced in the gut that exert various beneficial effects. However, its effect on SE colonization is not well known. The present study investigated the effect of sub-inhibitory concentrations (SICs) of sodium butyrate on the adhesion and invasion of SE in primary chicken enterocytes and chicken macrophages. In addition, the …

Previous results from our lab have shown that using an optical sorter to identify Fusarium head blight (FHB) resistant breeding lines was effective at reducing the toxin deoxynivalenol (DON) and FHB-associated kernel damage. In this paper we quantified the proportion of desirable genotypes at FHB resistance QTL in lines from three selection cycles of optical sorting. Breeding lines were genotyped at loci on chromosomes 3BS, 2DL, and 5A using the following DNA markers: TaHRC, CFD233, and GWM304. TaHRC is a KASP marker for Fhb1, a major FHB resistance QTL on chromosome 3BS. CFD233 is an SSR marker for Qfhs.nau-2DL …
Pre-Emergence Herbicides And Mulches For Weed Control In Cutting Propagation, Anthony L. Witcher, Isha Poudel
Pre-Emergence Herbicides And Mulches For Weed Control In Cutting Propagation, Anthony L. Witcher, Isha Poudel
Agricultural and Environmental Sciences Faculty Research
Weed control is critical in cutting propagation to maximize root growth and liner quality, but hand weeding is time consuming and not cost efficient. Pre-emergence herbicides are widely used in container-grown nursery crop production, but concerns of potential phytotoxicity have limited widespread use in propagation. Mulches are a viable alternative for weed control but few products have been evaluated in propagation. Five pre-emergence herbicides and five mulches were evaluated for rooting stem cuttings of three nursery crop species and for control of four weed species. Mulches were applied (0.8 cm depth) prior to sticking cuttings while pre-emergence herbicides were applied …

Socio-Economic And Environmental Implications Of Replacing Conventional Poultry Feed With Insect-Based Feed In Kenya, Zewdu Abro, Menale Kassie, Chrysantus Tanga, Dennis Beesigamukama, Gracious Diiro
All Peer-Reviewed Publications
The growing scarcity of resources for feed production and environmental concerns highlight the unsustainability of conventional feed sources. Insect farming is considered as an alternative feed due to its low land and water requirements, its low ecological footprint, and circular economy contribution by converting biowaste into high-quality feed ingredients. While there is growing research on the technical feasibility and nutritional performance of insect-based feed, its potential beneifts are not quanitified. Using experimental and secondary data, we assess the potential socio-economic benefits of black soldier fly larvae meal (BSFLM) to the Kenyan poultry sector. We find that replacing 5–50% of the …

Aspen Bibliography
Based on a generated database of 413 sample plots, with definitions of stand biomass of the genus Populus spp. in Eurasia, from France to Japan and southern China, statistically significant changes in the structure of forest stand biomass were found, with shifts in winter temperatures and average annual precipitation. When analyzing the reaction of the structure of the biomass of the genus Populus to temperature and precipitation in their transcontinental gradients, a clearly expressed positive relationship of all components of the biomass with the temperature in January is visible. Their relationship with precipitation is less clear; in warm climate zones, …

Antioxidant Characterization Of Peanut Hairy Root Extracts Enriched With Prenylated Stilbenoids, Patrick Roberto
Antioxidant Characterization Of Peanut Hairy Root Extracts Enriched With Prenylated Stilbenoids, Patrick Roberto
Student Theses and Dissertations
Peanut (Arachis hypogaea) is a prolific producer of prenylated stilbenoids that may confer health benefits in humans by their antioxidant activity. Therefore, the objective of this study was to use peanut hairy roots as a bioproduction system of extracts enriched with prenylated stilbenoids and evaluate their antioxidant activity in vitro. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay suggested that the whole extract and pure prenylated stilbenoids exhibit antioxidant activity. High-performance liquid chromatography combined with DPPH identified arachidin-1, arachidin-3, and arachidin-5 as the principle antioxidants in the extract. The DPPH assay revealed that the arachidin portion of the extract contains greater antioxidant capacity than …
