Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Assessment of the ecosystem services provided by urban trees in the "monumental zone" of the city of Iquitos, Loreto - Peru, 2023

Creator:: Tuesta Cartagena, Bruno Gonzalo
Abstract:: The growing urban development and the inadequate installation of settlements has caused environmental challenges such as landscape destruction, loss of urban tree biodiversity, therefore, the objective of this study was to identify the ecosystem services of urban trees in the 'Monumental Zone' of the city of Iquitos, in the Peruvian...

Measuring Combine Facilitated Transport of Italian Ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] Seed During Wheat Harvest and Preventing the Distribution of Italian Ryegrass Seed During Harvest by Removal or Destruction of Chaff

Creator:: Roerig, Kyle C.
Abstract:: Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] resistant to multiple herbicide sites of action continues to limit winter wheat production in western Oregon. In addition to impacting wheat production, multiple resistant Italian ryegrass may threaten the market for annual ryegrass seed for cover crops if wheat fields with...

Breeding, Production, and Morphophysiology Among Cytotypes of Common and Portuguese Cherrylaurel

Creator:: Schulze, Justin A.
Abstract:: The common cherrylaurel (Prunus laurocerasus) and Portuguese cherrylaurel (P. lusitanica) are economically important landscape shrubs across the United States. To gain a better understanding of physiology and morphology in these higher level polyploids (P. lusitanica, 2n = 8x; P. laurocerasus, 2n =22x), a variety of breeding experiments were performed. The...

Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens

Creator:: Mattox, Clint M.
Abstract:: Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

Stand structures of Oregon white oak (Quercus garryana) woodlands and their relationships to the environment in southwestern Oregon

Creator:: Gilligan, Laurie A.
Abstract:: Large areas of non-coniferous communities in southwestern Oregon are thinned to reduce fire hazard and accomplish ecosystem restoration, under the assumption that current fuel loads are unnaturally high. Although Oregon white oak (Quercus garryana) woodlands are a characteristic landscape component in this region, little is known about their current or...

Disease resistance and spring phenological characteristics of Ribes L. germplasm

Creator:: Dalton, Daniel T.
Abstract:: North American cultivation of Ribes L. may expand as small fruit growers seek species to diversify horticultural crops. The Ribes industry was suppressed for decades out of fear that cultivated black currants and gooseberries would intensify the fungal disease white pine blister rust (WPBR) on five-needle pine (Pinus L. section...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...

Fingerprinting, reproductive behavior and pollinator dynamics of Buddleja davidii and interspecific hybrids

Creator:: Still, Cara M.
Abstract:: Buddleja davidii (butterfly bush) is a highly adaptable landscape plant known for pollinator attraction. Unfortunately, it is also regarded as an invasive plant in highly disturbed environments across the globe. It is an invasive species in Oregon, officially classified as a class B noxious weed in 2004. Currently the state...
