The Manuscript Works Of S. Fred Prince (1857-1951), Sarah Burke Cahalan, Jason W. Dean 2018 University of Dayton

The Manuscript Works Of S. Fred Prince (1857-1951), Sarah Burke Cahalan, Jason W. Dean

Marian Library/IMRI Faculty Publications

S. Fred Prince, a botanical illustrator and amateur scientist, is a largely unknown artist whose work on the American landscape demonstrates his eligibility to be considered in the lineage of self-taught illustrator-naturalists such as Mark Catesby and Genevieve Jones. In this article, we present a survey of extant Prince materials identified at time of writing, describing their contents and physical characteristics. Beyond this survey and description, we also provide a biographical sketch and timeline of Prince's life.

Agronomy & Horticulture -- Faculty Publications

A Palmer amaranth (Amaranthus palmeri S. Watson) biotype has evolved resistance to photosystem (PS) II- (atrazine) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides (mesotrione, tembotrione, and topramezone) in maize seed production field in Nebraska, USA. The objectives of this study were to determine the effect of soil residual pre-emergence (PRE) herbicides followed by (fb) tank-mixture of residual and foliar active post-emergence (POST) herbicides on PS-II- and HPPD-inhibitor-resistant Palmer amaranth control, maize yield, and net economic returns. Field experiments were conducted in a grower’s field infested with PS II- and HPPD-inhibitor-resistant Palmer amaranth near Shickley in Fillmore County, Nebraska, USA in ...


Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder 2018 Purdue University

Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder

Engagement & Service-Learning Summit: Reciprocal & Sustainable Partnerships

The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its ...

The exhibit provided a way for the Libraries to promote an archival collection that not only closely connected with the University’s mission as a Catholic institution, but also provided ...


Historical Change Of Seagrasses In The Mississippi And Chandeleur Sounds, Linh Thuy Pham 2017 University of Southern Mississippi

Historical Change Of Seagrasses In The Mississippi And Chandeleur Sounds, Linh Thuy Pham

Dissertations

Seagrasses are important coastal resources facing numerous stressors, and losses have been documented from local to global assessments. Under the broad theme of habitat loss and fragmentation, a study of historical change in total area and landscape configuration of seagrasses in the Mississippi and Chandeleur Sounds was conducted. Mapping data was collated from a multitude of previous projects from 1940 to 2011.

Comparisons of seagrass area among various studies that used different mapping methods can result in overestimation of area change and misleading conclusions of change over time. The vegetated seagrass area (VSA) data were generalized to a common resolution ...


Genome Wide Co-Expression Among The Starch Debranching Enzyme Genes Atisa1, Atisa2, And Atisa3 In Arabidopsis Thaliana, Ling Li, Hilal Ilarslan, Martha G. James, Alan M. Myers, Eve Syrkin Wurtele 2017 Iowa State University

Genome Wide Co-Expression Among The Starch Debranching Enzyme Genes Atisa1, Atisa2, And Atisa3 In Arabidopsis Thaliana, Ling Li, Hilal Ilarslan, Martha G. James, Alan M. Myers, Eve Syrkin Wurtele

Eve Wurtele

Each of four starch debranching enzymes (DBE) is distinct and highly conserved across the plant kingdom; however, the specific functions of these proteins in carbohydrate metabolism are not well understood. DBEs function in both biosynthesis and degradation of starch, and two have been shown to function as multimers in various quarternary structures that can contain one or more DBE proteins, i.e. ISA1 homomultimers and ISA1/ISA2 heteromultimers. This study characterizes potential functional relationships between the three isoamylase-type DBE proteins (ISA) of Arabidopsis using a comprehensive bioinformatics analysis and promoter fusion approach to determine tissue-, subcellular-, and temporal specificity of ...


Phylogenetic Patterns Of Foliar Mineral Nutrient Accumulation Among Gypsophiles And Their Relatives In The Chihuahuan Desert, Rebecca E. Drenovsky, Clare Muller, Michael J. Moore, Zoe Feder, Helene Tiley 2017 John Carroll University

Phylogenetic Patterns Of Foliar Mineral Nutrient Accumulation Among Gypsophiles And Their Relatives In The Chihuahuan Desert, Rebecca E. Drenovsky, Clare Muller, Michael J. Moore, Zoe Feder, Helene Tiley

Rebecca E. Drenovsky

PREMISE OF THE STUDY: Gypsum endemism in plants (gypsophily) is common on gypsum outcrops worldwide, but little is known about the functional ecology of Chihuahuan Desert gypsophiles. We investigated whether leaf chemistry of gypsophile lineages from the northern Chihuahuan Desert are similar to leaves of related nonendemic (gypsovag) species relative to their soil chemistry. We expected widely distributed gypsophiles (hypothesized to be older lineages on gypsum) would have distinct leaf chemistry from narrowly distributed, relatively younger lineages endemic to gypsum and gypsovags, refl ecting adaptation to gypsum. METHODS: We collected leaves from 23 gypsophiles and related nonendemic taxa growing on ...

Agronomy & Horticulture -- Faculty Publications

Background: There are significant limitations in existing methods for the genome-wide identification of genes whose expression patterns affect traits.

Results: The transcriptomes of five tissues from 27 genetically diverse maize inbred lines were deeply sequenced to identify genes exhibiting high and low levels of expression variation across tissues or genotypes. Transcription factors are enriched among genes with the most variation in expression across tissues, as well as among genes with higher-than-median levels of variation in expression across genotypes. In contrast, transcription factors are depleted among genes whose expression is either highly stable or highly variable across genotypes. We developed a ...

Resin Monoterpene Defenses Decline Within Three Widespread Species Of Pine (Pinus) Along A 1530-M Elevational Gradient, Scott Ferrenberg, Joseph M. Langenhan, Jeffry B. Mitton

University Libraries Open Access Fund Supported Publications

The elevational gradient in plant defense (EGPD) hypothesis posits that natural enemy pressures increase alongside temperature across elevational climatic gradients, thereby selecting for enhanced defenses at lower elevations while leaving plants less defended at higher elevations. Phylogenetically constrained tests of this hypothesis are uncommon, with tests focused on defenses of mature trees in natural settings being exceedingly rare. In the absence of this information, predicting the spatiotemporal dynamics of forest pests that preferentially attack mature trees is rendered more difficult. Tree properties such as age, growth rate, and size have all been correlated with levels of tree defenses against insect ...

Effects Of Nitrogen And Phosphorus Fertilizer And Topsoil Amendment On Native Plant Cover In Roadside Revegetation Projects, Heidi L. Hillhouse, Walter H. Schacht, Jonathan M. Soper, Carol E. Wienhold 2017 University of Nebraska-Lincoln

Effects Of Nitrogen And Phosphorus Fertilizer And Topsoil Amendment On Native Plant Cover In Roadside Revegetation Projects, Heidi L. Hillhouse, Walter H. Schacht, Jonathan M. Soper, Carol E. Wienhold

Agronomy & Horticulture -- Faculty Publications

Establishing vegetation on roadsides following construction can be challenging, especially for relatively slow growing native species. Topsoil is generally removed during construction, and the surface soil following construction (“cut-slope soils”) is often compacted and low in nutrients, providing poor growing conditions for vegetation. Nebraska Department of Transportation (NDOT) protocols have historically called for nitrogen (N) and phosphorus (P) fertilization when planting roadside vegetation following construction, but these recommendations were developed for cool-season grass plantings and most current plantings use slower-establishing, native warmseason grasses that may benefit less than expected from current planting protocols. We evaluated the effects of nitrogen and ...


Floristic Response To Urbanization: Filtering Of The Bioregional Flora In Indianapolis, Indiana, Usa, Rebecca W. Dolan, Myla F.J. Aronson, Andrew L. Hipp 2017 Butler University

Floristic Response To Urbanization: Filtering Of The Bioregional Flora In Indianapolis, Indiana, Usa, Rebecca W. Dolan, Myla F.J. Aronson, Andrew L. Hipp

Rebecca W. Dolan

PREMISE OF THE STUDY: Globally, urban plant populations are becoming increasingly important, as these plants play a vital role in ameliorating effects of ecosystem disturbance and climate change. Urban environments act as filters to bioregional flora, presenting survival challenges to spontaneous plants. Yet, because of the paucity of inventory data on plants in landscapes both before and after urbanization, few studies have directly investigated this effect of urbanization. METHODS: We used historical, contemporary, and regional plant species inventories for Indianapolis, Indiana USA to evaluate how urbanization filters the bioregional flora based on species diversity, functional traits, and phylogenetic community structure ...

Flax As An Iowa Crop, Chas. S. Reddy, L. C. Burnett 2017 Iowa State College

Flax As An Iowa Crop, Chas. S. Reddy, L. C. Burnett

Bulletin

Among the grain crops in the United States, seed flax is exceeded in value by corn, wheat, oats and barley. It has approximately the same value as rye, rice and sorghums.

As a crop for new land, the flax seed acreage reached a peak (3,700,000 acres) in 1902, but gradually declined to little more than a million acres by 1922. As a crop for old land, taking its place in rotations, flax acreage reached a second peak equal to the first in 1930. Consumption of flax in the United States surpassed production in 1909 and for the past ...


Control Of Cherry Yellow-Leaf On Nursery Stock, George L. McNew, Donald E. Bliss 2017 Iowa State College

Control Of Cherry Yellow-Leaf On Nursery Stock, George L. Mcnew, Donald E. Bliss

Bulletin

Yellow-leaf, caused by the fungus Coccomyces hiemalis Higgins, is the most prevalent and destructive cherry disease in Iowa, since it often causes premature defoliation of both nursery and orchard trees. Early defoliation in nursery stock results in decreased growth during the current and subsequent years, and precludes all possibility of forcing the trees into marketable size in one growing season. In the orchard, defoliation may decrease fruit bud formation and vegetative growth and increase the amount of winterkilling.

All defoliated nursery stock must be held in the nursery row a second season, and even then many of the trees must ...


Control Of Glyphosate-Resistant Common Ragweed (Ambrosia Artemisiifolia L.) In Glufosinate-Resistant Soybean [Glycine Max (L.) Merr], Ethann R. Barnes, Stevan Z. Knezevic, Peter H. Sikkema, John L. Lindquist, Amit J. Jhala 2017 University of Nebraska-Lincoln

Control Of Glyphosate-Resistant Common Ragweed (Ambrosia Artemisiifolia L.) In Glufosinate-Resistant Soybean [Glycine Max (L.) Merr], Ethann R. Barnes, Stevan Z. Knezevic, Peter H. Sikkema, John L. Lindquist, Amit J. Jhala

Agronomy & Horticulture -- Faculty Publications

Common ragweed emerges early in the season in Nebraska, USA and is competitive with soybean; therefore, preplant herbicides are important for effective control. Glyphosate has been used as a preplant control option; however, confirmation of glyphosate-resistant (GR) common ragweed in Nebraska necessitates evaluating other herbicide options. The objectives of this study were to (1) evaluate the efficacy of preplant (PP) herbicides followed by (fb) glufosinate alone or in tank-mixture with imazethapyr, acetochlor, or S-metolachlor applied post-emergence (POST) for control of GR common ragweed in glufosinate-resistant soybean; (2) their effect on common ragweed density, biomass, and soybean yield; and (3) the ...


A Screen For Arabidopsis Thalianamutants With Altered Susceptibility To Heterodera Schachtii, T. J. Baum, M. J. E. Wubben II, K. A. Hardy, H. Su, S. R. Rodermel 2017 Iowa State University

A Screen For Arabidopsis Thalianamutants With Altered Susceptibility To Heterodera Schachtii, T. J. Baum, M. J. E. Wubben Ii, K. A. Hardy, H. Su, S. R. Rodermel

Thomas Baum

Genetic approaches are a powerful means to elucidate plant-pathogen interactions. An in vitro screening protocol was developed to identify Arabidopsis thaliana mutants with altered susceptibility to Heterodera schachtii, the sugar beet cyst nematode. In an initial screen of approximately 5,200 ethyl methanesulfonate-generated mutant plants, two stable mutations were identified. Both mutant lines were backcrossed and were found to harbor single recessive mutant alleles. Mutant line 2-4-6 shows an approximately two-fold increase in sedentary and developing nematodes, while mutant line 10-5-2 exhibits a significant decrease in susceptibility that manifests itself only after nematodes become sedentary. Analyses of progeny from crosses ...
