Living Seeds Of History: The John Stokes And Mary's Gardens Exhibit, Stephanie Shreffler, Kayla Harris

Kayla Harris

This panel describes how the University of Dayton planned and carried out an exhibit on the John Stokes and Mary’s Gardens archival collection, featuring a garden inside the library. A “Mary garden” is a garden filled with flowers named for Mary.

The panel describes the content of the collection and how the exhibit was originally conceived; the exhibit design and programming; and the challenges faced during the planning process.

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 new opportunities …

Top-Down And Bottom-Up Approaches To Understanding The Fate Of The Federally Endangered Schaus’ Swallowtail Butterfly (Heraclides Aristodemus Ponceanus), Jaeson T. Clayborn

FIU Electronic Theses and Dissertations

The federally endangered Schaus’ swallowtail butterfly (Heraclides aristodemus ponceanus) populations have declined precipitously over the years. Despite tremendous efforts to augment the numbers of this butterfly through captive-bred releases and habitat enhancements, it remains imperiled and federally endangered. The dissertation’s objectives were: 1) to restore dry forest habitat in Biscayne National Park (BNP) for Schaus’ swallowtails; 2) to assess host plant (torchwood and wild lime) survivorship and growth in the restoration sites (BNP) and project dry forest habitat loss because of imminent sea level rise (SLR); 3) to quantify ant activity and record predator-prey interactions against Heraclides caterpillars …

Systematics And Biogeography Of The Cortinarius Violaceus Group And Sequestrate Evolution In Cortinarius (Agaricales), Emma Harrower

Doctoral Dissertations

Phylogenetics is a powerful tool used for illuminating the diversity of life on Earth, their evolution and their ecology. I created a multi-gene phylogenetic tree of Cortinarius section Cortinarius and uncovered five previously overlooked species, increasing the number of species in the section from seven to twelve. All members of the clade possess both cheilocystidia and pleurocystidia and possess a pigment known as (R)-39,49-dihydroxybphenylalanine. Ancestral state reconstruction estimated that the ancestral host was most likely an angiosperm, switching hosts when encountering novel host species in new lands, and only C. violaceus associating with the Pinaceae in North America. Biogeographic analysis …

The tests provide information to companies developing varieties and/or marketing seed within the State, and aid the Arkansas Cooperative Extension Service in formulating variety recommendations for soybean producers.

A Swift Guide To Butterflies Of North America, Second Edition., Ann B. Swengel

The Prairie Naturalist

As soon as I got my hands on A Swift Guide to Butterflies of North America, I immediately checked the species account for Aphrodite Fritillary (Speyeria aphrodite). The prairie version of this species can be sufficiently different from the typically illustrated nominate subspecies such that it must be specifically explained as being distinct. This book passed my first test—describing details that were not only essential for identifying this fritillary species but also for realizing how similar its underside can be to our prairie specialty, the stunning Regal Fritillary (S. idalia).

Much of my research on butterflies occurs in grasslands. For …

Avian Diversity, Abundance, And Nest Success Among Managed Prairies And Agricultural Plots In Oklahoma And Texas, Phillip J. Leonard, Douglas R. Wood, Wayne E. Meyer

The Prairie Naturalist

Over the last 50 years, grassland birds experienced rapid declines due to habitat loss and degradation as a result of agricultural practices. Our objective was to document the diversity, abundance, and nest success of bird communities using managed prairie and agricultural plots at the Tishomingo National Wildlife Refuge (NWR) in southern Oklahoma and Hagerman NWR in northern Texas. From April 1 to July 15, 2013–2014, point count surveys, nest searches, nest monitoring, and vegetation sampling were conducted among three habitat treatments: managed prairie, unharvested wheat, and fallow agricultural plots. Species richness values for potential nesting species were higher in managed …

Severe Drought Impacts Female Pheasant Physiology In Southwest Nebraska, Jessica A. Laskowski, Gwen C. Bachman, Joseph J. Fontaine

The Prairie Naturalist

In 2012, Nebraska experienced one of the worst droughts since the 1930s, accompanied by abnormally high temperatures. We studied the impacts of the 2012 summer drought on female ring-necked pheasant (Phasianus colchicus) body condition and baseline and stress-induced corticosterone concentrations (CORT). We hypothesized that drought conditions would reduce pheasant body condition, increase chronic stress resulting in elevated baseline CORT levels, and down-regulate pheasant stress response to acute stressors, resulting in reduced stress-induced CORT concentrations. In southwestern Nebraska, we captured female pheasants in 2012 (pre-drought) and 2013 (post-drought). Pheasants had poorer body condition after the drought. Although female CORT measures were …

Energy Sprawl Solutions, Nicola Koper

The Prairie Naturalist

Energy sprawl affects all the major conservation issues of our age, from habitat loss and fragmentation to anthropogenic noise and climate change. As such, minimizing and solving its associated problems should be a key focus for conservation biologists. Kiesecker and Naugle provide an impressive and compact book that focusses on solving environmental and social problems likely to result from a transition from non- renewable to far less efficient renewable energy sources.

Energy Sprawl Solutions summarizes numerous relevant peer-reviewed academic papers, and outlines management and planning implications of each one, ultimately resolving these into fairly clear prescriptive recommendations for moving forward. …

Unique Nesting Behavior By Trumpeter Swans (Cygnus Buccinator), Heather M. Johnson, Michael Forsberg, Letitia Reichart, Mark P. Vrtiska

The Prairie Naturalist

Nesting behavior by Trumpeter swans (Cygnus buccinator) has been well documented for most populations. Both sexes cooperate in nest construction, which takes 11–35 days to complete (Hansen et al. 1971, Cooper 1979). Nests generally range from 1.5–3.6 meters in diameter and 1.5 meters in height and are typically built on solid structures such as a muskrat (Ondatra zibethicus) house or an island (Hansen et al. 1971, Cooper 1979). However, we discovered an atypical Trumpeter swan nest built of cattail (Typha angustifolia L.) located on Vaughn Lake, in Cherry County, Nebraska on 13 May 2016.

We monitored the atypical nest by …

The Considerations Given To Determining Authorship, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! Over the past year, I have been asked by prospective authors and colleagues whether The Prairie Naturalist has criteria for authorship. Given that this issue continues to arise, it is comforting to know that I am not the only one who struggles with considerations given to determining authorship. I checked the current submission guidelines and found nothing specific, which in turn motivated me to explore what other journals such as the Journal of Wildlife Management, Proceedings of the National Academy of Sciences, and Ecology recommend to prospective authors (Merrill 2015). Much to my surprise, discussions of authorship …

One More Warbler: A Life With Birds., Laura Erickson

The Prairie Naturalist

Imagine going on a Victor Emanuel Nature Tour, seated in the van next to Victor Emanuel himself. Between birding stops, this man who has seen over 6,000 species as a world-renowned conservationist and innovator in ecotourism regales you with stories. He starts with his “spark bird”: when he was eight years old, he was taken with the beauty of a pair of Northern Cardinals (Cardinalis cardinalis), and was hooked. Whenever people pile back into the van after a birding stop, he starts another story.

That’s how One More Warbler: A Life with Birds reads, as if Emanuel sat down with …

Notes: Range Extension Of The Virginia Opossum (Didelphis Virginiana) In North Dakota, Lisa L. Walsh, Robert Seabloom, Cody W. Thompson

The Prairie Naturalist

The Virginia opossum (Didelphis virginiana) is broadly distributed across North America from Costa Rica in the south to southern Ontario in the north and from the southern Great Plains in the west to the eastern United States. The Virginia opossum also was introduced multiple times to thePacific Coast beginning in the late 1800s and has established populations in that region (Gardner and Sunquist 2003). This species is a habitat generalist known to frequent wetland and hardwood habitats but also can be found in grasslands, along forest edges, and in agricultural and suburban settings throughout its range (Gardner and Sunquist 2003, …

Prairie Falcon Depredation Attempts On A Greater Prairie-Chicken Lek In South-Central Nebraska, Andrew J. Caven, Joshua D. Wiese, William R. Wallauer

The Prairie Naturalist

Little information exists concerning Prairie falcons’ (Falco mexicanus; PRFA) seasonal movements, habitat use, and diet outside of the breeding season; this is especially true in the eastern portion of its wintering and migratory range (Steenhof 1998, Sharpe et al. 2001, Steenhof et al. 2005). Prairie falcons prey on ground squirrels (Spermophilus spp.), prairie dogs (Cynomys spp.), wood rats (Neotoma spp.), and other rodents during the breeding season (Bond 1936, 1942, MacLaren et al. 1988, Steenhof 1998, Steenhof et al. 1999, Johnsgard 2013). They utilize avian prey regionally as well, including western meadowlarks (Sturnella neglecta …

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 …

Book Reviews: Raptors Of Mexico And Central America. William S. Clark And N. John Schmitt., Jack Jack Eitniear

The Prairie Naturalist

Whether a raptor is cryptically perched in the shadows or is viewed only as a silhouette soaring in the clouds below the glaring midday sun, raptor identification can be challenging. If you are observing raptors in the North Temperate Zone, several guides (e.g., Clark and Wheeler 2001 Dunne et al.2012) will aid you with such identifications, but few resources exist for visitors south of this zone. So, if you are interested in identifying the 69 species of diurnal raptors found in Mexico and Central America, the recently released Raptors of Mexico and Central America by William S. Clark and N. …

Field Discrimination Of Prairie Deer Mice And White-Footed Mice Using Morphological Characteristics, Jacob L. Berl, Kelton M. Verble, Elizabeth A. Flaherty, Robert K.S. Swihart

The Prairie Naturalist

Field discrimination of prairie deer mice (Peromyscus maniculatus bairdii) and white-footed mice (P. leucopus noveboracensis) can be difficult throughout much of the central United States where they co-occur. We live-trapped prairie deer mice and white-footed mice within forested and row-crop habitats in central Indiana and used multiplex PCR with species-specific primers to positively determine species identification. We collected a suite of commonly measured external morphological traits (body weight and lengths of ear, hindfoot, tail, and body) from each captured animal. Individuals were assigned to species based on analysis of DNA; discriminant function analysis was used to …

Substantial Contribution Of Genetic Variation In The Expression Of Transcription Factors To Phenotypic Variation Revealed By Erd-Gwas, Hung-Ying Lin, Qiang Liu, Xiao Li, Jinliang Yang, Sanzhen Liu, Yinlian Huang, Michael J. Scanlon, Dan Nettleton, Patrick S. Schnable

Department of Agronomy and 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 …

Estimation Of Irrigation Requirements For Drip-Irrigated Maize In A Sub-Humid Climate, Liu Yang, Hai-Shun Yang, Jiu-Sheng Li, Yan-Feng Li, Hai-Jun Yan

Department of Agronomy and Horticulture: Faculty Publications

Drip-irrigation is increasingly applied in maize (Zea mays L.) production in sub-humid region. It is critical to quantify irrigation requirements during different growth stages under diverse climatic conditions. In this study, the Hybrid-Maize model was calibrated and applied in a sub-humid Heilongjiang Province in Northeast China to estimate irrigation requirements for drip irrigated maize during different crop physiological development stages and under diverse agro-climatic conditions. Using dimensionless scales, the whole growing season of maize was divided into diverse development stages from planting to maturity. Drip-irrigation dates and irrigation amounts in each irrigation event were simulated and summarized in 30-year simulation …

Identifying Ecologically Relevant Scales Of Habitat Selection: Diel Habitat Selection In Elk, Caleb P. Roberts, James W. Cain Iii, Robert D. Cox

Department of Agronomy and Horticulture: Faculty Publications

Although organisms make resource selection decisions at multiple spatiotemporal scales, not all scales are ecologically relevant to any given organism. Ecological patterns and rhythms such as behavioral and climatic patterns may provide a consistent method for identifying ecologically relevant scales of habitat selection. Using elk (Cervus canadensis) as an example species, we sought to test the ability of behavioral patterns to empirically partition diel scales for modeling habitat selection. We used model selection to partition diel scales by shifts in dominant behavior and then used resource selection probability functions to model elk habitat selection hierarchically at diel scales within seasons. …

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

2017 Faculty Bibliography

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, reflecting adaptation to gypsum.

METHODS: We collected leaves from 23 gypsophiles and related nonendemic taxa growing on nongypsum …

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

Department of Agronomy and 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 …

Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke

Independent Study Project (ISP) Collection

Northern residing plant species are at the highest risk for extinction due to temperature rise related to climate change (Schöb, Manuel, Choler & Veit, 2009). Climate change has also led to a northern shift in the geographic distribution of plant species (Parmesan & Yohe, 2003). This could lead to a necessary alteration in the way natural resources are utilized in arctic countries like Iceland (Lim-Camacho et al, 2017). The purpose of this study is to analyze the way in which Icelandic plant species used in natural dye practices may shift in distribution due to climate change and the potential impact …

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. …
