Crepe Myrtle Bark Scale (Acanthococcus Lagerstroemiae) And Sooty Mold (Capnodium Sp.) Decrease Bloom And Fruit Number In ‘Natchez’ Crepe Myrtle (Lagerstroemia Xfauriei ‘Natchez’), Derald A. Harp, Beatriz Ruiz, Kara Bailey, Pedro Castillo, Phoebe Alvarez

Faculty Publications

Crepe myrtle bark scale (CMBS) (Acanthococcus lagerstroemiae) is an important pest of crepe myrtle in Texas, and infestations are accompanied by excessive growth of sooty mold (SM) that will cover stems, and, in severe cases, leaves. These combine to create significant stress on the plant, and anecdotal evidence suggests a decrease in bloom number under heavy infestation. In an existing planting of 24 ‘Natchez’ crepe myrtle in four blocks, three trees were randomly chosen in each block and treated with either a dinotefuran (year 1) or imidicloprid (year 2) drench. The three remaining trees were untreated. In February of year …

Biodiversity Between The Vines: Common, Rare, And Weedy Plants In Willamette Valley Vinyards, Nora Dunkirk, Gabriel Campbell

Institute for Natural Resources Publications

Vineyards in the Willamette valley are more than rows of grapes—they are living landscapes. Between the vines is a diverse community of over 1,500 plant species that support soil health, pollinators and beneficial insects, birds and other wildlife, and contribute meaningfully to the resiliency and productivity of vineyards. Among the natives are also introduced and exotic plants that compete with the native species. Every plant tells a story—together, they form a living vineyard. Here we present common, rare, and exotic weedy species of Willamette Valley vineyards along with identification tips about each species. Presented at the 2026 LIVE conference (livecertified.org).

Evaluation Of Publicly Available Maize Germplasm Adaptation To Environments In Nebraska, Garrett Snodgrass Mar 2026

Evaluation Of Publicly Available Maize Germplasm Adaptation To Environments In Nebraska, Garrett Snodgrass

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Publicly available maize germplasm represents an important resource for breeding programs seeking to expand genetic diversity and improve hybrid performance. However, effective use requires characterization of per se phenotypic performance of parental lines and evaluation of the parental line’s hybrid progeny adaptation to a given target population of environments. Furthermore, understanding population structure and heterotic grouping is imperative for maximizing efficiency of breeding decisions. The objectives of this study were to (1) evaluate phenotypic performance of parental lines and hybrids across environments in Nebraska, and to (2) refine heterotic group classification of parental lines within the University of Nebraska-Lincoln’s Hybrid …

A Simple And Affordable Protocol To Assess Censer Seed Dispersal: First Confirmation Of The Mechanism In The Genus Solanum, Abigail J. Motter, Christopher T. Martine, Melody P. Sain Jan 2026

A Simple And Affordable Protocol To Assess Censer Seed Dispersal: First Confirmation Of The Mechanism In The Genus Solanum, Abigail J. Motter, Christopher T. Martine, Melody P. Sain

Faculty Journal Articles

The censer seed dispersal mechanism, whereby mature fruits are retained on plants and seeds dispersed by mechanical shaking, is among the most specialized wind-aided seed dispersal strategies employed by the flowering plants. An efficient, affordable, and easily repeatable protocol for determining whether a species uses this unusual mechanism of seed dispersal is lacking. Our focal species, Solanum tudununggae, is one of just two Solanum species (in a fleshy-fruited genus of ca. 1200 species) hypothesized to use this dispersal mechanism as a means to move seeds farther from parent plants than would gravity alone.

Phylogeography, Fungal Host Specificity, And Fitness In The Corallorhiza Maculata Species Complex, Hana Thixton-Nolan Jan 2026

Phylogeography, Fungal Host Specificity, And Fitness In The Corallorhiza Maculata Species Complex, Hana Thixton-Nolan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mycoheterotrophic plants exploit fungi for most or all nutritional needs, providing a compelling system to address the evolutionary consequences of genome reduction, population-level variation, and germination requirements. I am using the widespread Corallorhiza maculata species complex to address questions of genomic variation, fungal host specificity, morphological variation, and germination requirements across the broad geographic range from Mexico to northern North America. This complex contains C. bulbosa, C. macrantha, and C. mertensiana, the latter with three varieties (maculata, occidentalis, and mexicana). These taxa vary in flowering time, floral morphology, and fungal associations. However, the degree …

Evaluating Donor Site Recovery Following Halodule Wrightii Harvest For Restoration In Northwest Florida, Katie M. Konchar, Becca A. Hatchell, Colin P. Shea, Bradley T. Furman, Kent Smith

Gulf and Caribbean Research

Bare‑root harvesting of Halodule wrightii is widely used to supply donor material for seagrass restoration, yet the capacity of donor meadows to recover in near‑temperate systems remains poorly documented. We evaluated donor‑site recovery following bare‑root harvesting in St. Andrew Bay, northwest Florida—an estuary at the northern extent of Tropical Atlantic Bioregion 2 where H. wrightii exhibits strong seasonal senescence and a shortened growing season. Thirty harvest impact sites were monitored for 388 days to quantify changes in shoot density, percent frequency, and sediment elevation relative to nearby reference conditions. Shoot density and percent frequency at harvested sites converged with reference …

Factors Affecting Diet Selection In Sheep Fed Endophyte-Infected Toxic Fescue, Jordan Thomas, Ronelson Stinfil, Kenneth P. Coffey, Christine C. Nieman, Derico Setyabrata, Shawna Weimer

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) infected with toxin‑producing fungi can induce fescue toxicosis in grazing ruminants, reducing performance and altering forage intake. Chemical compounds in red clover (Trifolium pratense), such as biochanin A, have been proposed to mitigate these effects by improving palatability and blood vessel relaxation. This study examined whether the inclusion of ground red clover (GRC), either alone or in combination with hydroxypropyl methylcellulose (HPMC) and polyethylene glycol (PEG), affected voluntary diet selection in lambs offered toxic fescue. Thirty‑three lambs were housed individually and assigned randomly to one of four diets: (1) toxic …

[Review Of The Book A Conspectus Of The North American Isoetaceae, By D. F. Brunton, J. T. Kartesz, M. Nishino, And P. C. Sokoloff]., Lytton John Musselman

Biological Sciences Faculty Publications

Isoetes (Isoetaceae; Lycopodiopsida; quillworts) constitutes a highly successful, cosmopolitan genus with over 200 species. Isoetes is derived from isos Greek for equal and eter for year, referring to the typically long persisting leaves of the sole genus in this ancient plant family. The leaves resemble a ‘quill-of-feather,’ hence the common name ‘Quillworts,’ wort, from old Germanic wurti, meaning plant. In large measure due to its simple form, inconspicuous appearance and negligible economic value, it represents one of the least studied and least collected of all North American genera. Isoetes constitutes a taxonomically enigmatic group with numerous polyploid species that arose …

Extending The Fruiting Season With Container Grown Primocane-Fruiting Blackberries Grown In A High-Tunnel, Edwin James Tucker Iii Jan 2026

Extending The Fruiting Season With Container Grown Primocane-Fruiting Blackberries Grown In A High-Tunnel, Edwin James Tucker Iii

Graduate Theses/Dissertations

Blackberry production has become an important part of many small fruit orchard operations because they’re easy to grow, produce a large crop, and sell well at market. The current blackberry season in Missouri extends from mid-June to mid-August, depending on the cultivar chosen. This fruiting season is common for floricane-fruiting blackberry cultivars (cultivars that fruit on one-year old canes). Primocane-fruiting blackberry, or blackberries that fruit on current season growth, have the potential to further extend the harvest season of blackberry into September and October especially if grown in a high-tunnel. This study had two objectives. The first objective was to …

Sex In Plants: Birth, Death, And Trying To Survive In Changing Climates, Elena M. Meyer Jan 2026

Sex In Plants: Birth, Death, And Trying To Survive In Changing Climates, Elena M. Meyer

Theses and Dissertations

Plant mating systems are key determinants of fitness. Angiosperms exhibit a wide variety of reproductive strategies, including self-fertilization (or selfing), outcrossing, and mixed mating. It has been estimated that up to 43% of plant species are capable of selfing, and selfing has been hypothesized to provide reproductive assurance where opportunities for mating may be limited, such as in marginal environments. However, questions regarding the overall distribution of selfing rates across angiosperms, the maintenance of mixed mating in the face of inbreeding depression, and the impact of self-fertilization on diversification rates remain incompletely resolved. Here, we explore the dynamics of self-fertilization …

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr. Jan 2026

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr.

UROP Posters

Understanding the relatedness of angiosperms and the evolution of their inflorescence remains challenging, as these structures are highly modified and prone to convergent evolution. The current research describing inflorescence architecture, whether genetically or morphologically focused, typically relies on text based explanations, 2D images, or 3D based models created with CAD modeling software. This creates a disparity in the reader's understanding of these models since descriptions rely heavily on the author's interpretation of the inflorescence. The goal of our study is to bridge this disconnection by producing anatomically and color-correct 3D inflorescence models using Solanaceae flowers that readers can explore directly, …

Succession And Alpine Plant Habitat Of A Recently Deglaciated Foreland In The Trinity Alps, California, Sebastian Evans Jan 2026

Succession And Alpine Plant Habitat Of A Recently Deglaciated Foreland In The Trinity Alps, California, Sebastian Evans

Cal Poly Humboldt theses and projects

The recent extinction of the Salmon Glacier in the Trinity Alps, California, provides a rare opportunity to examine post-glacial succession in a region of high endemism experiencing climatic stress. Using a chronosequence spanning ~150 years since deglaciation, I investigated (1) vegetation successional trajectories in the foreland, (2) whether the foreland functions as a climate refugium for alpine specialists, and (3) whether facilitative interactions between the dominant vascular plant (DVP) and bryophytes occur and persist through succession. I surveyed 100 plots across 11 transects within the foreland and 40 randomized plots in adjacent ecosystems. Successional patterns and refugial potential were analyzed …

Species Boundaries Of The Rare Menzies’ Wallflower (Brassicaceae: Erysimum Menziesii), An Endemic Of The Northern California Coast, Cameron M. Jones

Cal Poly Humboldt theses and projects

Morphological similarity among geographically isolated populations can obscure deep evolutionary divergence, especially when convergent evolution under similar environmental conditions yields comparable phenotypes across independent lineages. Such cryptic diversity is likely underestimated in hotspots like the California Floristic Province (CFP), a global biodiversity hotspot, defined by its Mediterranean-like climate and encompassing most of California, southwestern Oregon, and northwest Baja California. The CFP is home to a disproportionate number of narrow endemics whose origins and evolutionary relationships remain poorly understood. Here, I investigate the evolutionary origins of Erysimum menziesii (Brassicaceae), a federally endangered California coastal dune endemic whose fragmented distribution has led …
