Listen To The Birds: Sound Ecology At The Piano, Anna Showalter

Dissertations, 2020-current

This document explores the intersection between birdsong and piano music using four cases studies from the piano repertoire in the Western classical tradition. Using Jeff Titon’s framework of “sound ecology” as a lens, I ask whether the following pieces of music could in some way function as an “acoustic tissue among human and bird communities that becomes the basis for a healthy economy and a just community.” After exploring the history of birdsong in the piano literature as a microcosm of shifting attitudes toward birdsong in Western art music this study focuses on four pieces as case studies for analysis—Amy …

Heat Increment Of Feeding In The Common Bottlenose Dolphin (Tursiops Truncatus) Contributes Moderately To Field Metabolic Rate Estimates, Ioulia Koliopoulou, Stacy L. De Ruiter, Jordi Altimiras, Josefin Larsson, Julietta Arenarez, David Rosen, Andreas Fahlman

University Faculty Publications and Creative Works

Digestion elevates metabolism through the heat increment of feeding (HIF) – the energy expended on mechanical and biochemical processes after eating. Quantifying this cost is essential for bioenergetic models that predict energy flow and prey requirements in populations. Using breath-by-breath respirometry, we measured oxygen consumption (V̇ O2 ) in eight common bottlenose dolphins (Tursiops truncatus) before and after feeding standardized meals (1659–2658 kcal of capelin and herring). Metabolic rate rose by ∼37% above resting levels, peaking 60 min after feeding before returning to baseline within 2 h. When scaled across the day, digestion increased daily metabolic needs by ∼8.2% of …

Trace Mineral Supplementation Strategies For Beef Cattle During Preconditioning And Feedlot Receiving, Madeline G. Mcknight

Theses and Dissertations

Beef cattle routinely undergo a variety of stressors within the preconditioning and feedlot receiving phases which may impair animal performance and health. Trace mineral supplementation, either through dietary or injectable sources, is proposed to mitigate these effects through metabolic and immune system support. Two systematic reviews and meta-analyses were conducted to evaluate the efficacy of two different oral supplementation methods, organic (OTM) and inorganic (INR), and injectable trace mineral (ITM) solutions on average daily gain (ADG) and morbidity. Across 20 studies, OTM supplementation increased ADG (P = 0.01) when compared to INR, but did not affect morbidity (P = 0.92). …

White Nose Syndrome In Bats And Infant Mortality In Georgia, Rhys Medcalfe, Sean Medcalfe, Simon Medcalfe

Journal of the Georgia Public Health Association

Background: White nose syndrome (WNS) is a disease in bats caused by the fungus Pseudogymnoascus destructans that can result in bat mortality rates of over 90%. WNS was discovered in Georgia in 2012 in 3 counties but has continued to spread to 14 counties as of 2023, with P. destructans detected in a further seven. Biodiversity loss has been linked to human health outcomes including infant mortality. Understanding the link between WNS, biodiversity loss, and infant mortality in Georgia is important because Georgia ranks 42^nd out of the 50 states for infant mortality rate.

Methods: Using panel data from …

Dietary Supplementation In Lambs: Evaluating The Effects Of Depth Charge On Meat Composition, Alianna Koesel

Student Scholar Symposium

Often, animals destined for consumption are fed supplements to help speed up or slow down their growth rate, enhance aesthetics, or standardize the product. Herein, we examined the supplement Depth Charge and its effects on the fat and protein content in lambs of the same age and lineage. Depth Charge increases fiber consumption to add spring of rib or an outward rib cage curvature to an animal's appearance while restricting feed consumption. Since the supplement targets the rib-loin area, we chose to analyze loin chop, loin roast, and hamburger cuts from each lamb and conducted experiments to determine how each …

Ponter, Winai Kaewlamun

The Thai Journal of Veterinary Medicine

The present study evaluated the independent effects of ovarian characteristics and oral propylene glycol (PG) supplementation on pregnancy rates in suckled beef cows subjected to the 7-day CO-Synch + CIDR fixed-time AI (FTAI) protocol across different seasons, body condition scores (BCS; 5-point scale), and parturition-to-FTAI intervals. Cows received a CIDR insert and 10 μg GnRH on day -10, followed by 25 mg PGF2α at CIDR removal on day -3, and another 10 μg GnRH 72 h later (day 0). In Study 1, the ovarian characteristics of 36 cows were assessed transrectally on days -10 and 0 relative to the FTAI. …

An Updated Annotated Checklist Of The Mammals Of The Crane Trust, Hall County, Nebraska, Bethany L. Ostrom, Amanda H. Medaries, Andrew J. Caven, Jenna M. Malzahn, Alexa Rojas, Matthew R. Schaaf, David M. Baasch, Thomas E. Labedz, Greg D. Wright

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Crane Trust is a regional nonprofit conservation organization that has protected land in the biologically important Central Platte River Valley for over four decades. A mammal inventory was conducted on the Crane Trust’s main habitat complex in 1980. Since, a variety of environmental conditions have shifted locally, regionally, and globally. An analysis of the mammal community was conducted using past and recent data to determine how species composition and relative abundance have shifted categorically from 1980 to 2021. We used all available data to categorize relative abundance during two distinct time periods per a modified “DAFOR” scale including 7 …

Fisheries Research Report No. 362: Characterising Essential Benthic Habitats And Environmental Drivers Of Fishery Recruitment In The Exmouth Gulf Prawn Managed Fishery, Scott Evans, Nick Konzewitsch, Rachel Marks, Renae Hovey, Gary A. Kendrick, Lynda M. Bellchambers

Fisheries Research Reports

Fisheries management relies on the development and evolution of effective assessment and monitoring techniques that are applicable in a range of fishery contexts (Fletcher et al., 2016; L. M. Robinson et al., 2021). The assessment of fish habitats and environmental drivers that influence recruitment is central to sustainable fisheries management (de Lestang et al., 2010; Galindo-Cortes et al., 2010; Gao & Wang, 2021). Western Australia conducts robust fishery-specific monitoring and assessment programs to ensure the sustainable use of its aquatic resources (Newman et al., 2023). However, few long-term datasets exist that directly monitor critical fish habitats and environmental conditions that …

Impacts Of Including Sprouted Barley In The Diet Of Beef Cattle On Production, Ruminal Health, And Meat Quality, Zachary C. Crump

All Graduate Theses and Dissertations, Fall 2023 to Present

Beef producers in the United States are working to meet rising global demand for animal protein while facing major challenges such as drought, climate uncertainty, and rapid urbanization. These issues make it difficult to produce consistent and dependable feed, pushing producers to explore new ways to grow feed using fewer natural resources. Vertical farming systems are one option that can grow sprouted cereal grains indoors throughout the year while using decreased land and water than traditional agriculture. Sprouted barley grows within six to seven days and may serve as a nutrient dense alternative feed source for cattle at several stages …

First Definitive Records Of Hermit Thrush And Wilson’S Warbler Subspecies For Nebraska, Stephen J. Brenner, Joel G. Jorgensen

Nebraska Bird Review

During the fall of 2025, we initiated a pilot migratory bird-banding project in the Nebraska Panhandle. While the project’s goals included examining species composition, volume, and body condition of migratory birds at the western edge of the state compared to the eastern edge of the state, we also used this project to document the occurrence of subspecies and species which are very challenging or impossible to identify through field observation. Here, we report on the first definitive records of two subspecies in Nebraska.

On 16 September 2025, SJB banded an adult male Wilson’s Warbler (Cardellina pusilla) that was …

Fall Field Report, August–November 2025, W. Ross Silcock

Nebraska Bird Review

As in previous fall seasons, by far the most modifications to BONO came from late departure dates; around 87 species were included, no fewer than 13 of these setting record late dates, notably Eastern Whip-poor-will, Mountain Plover, Brown Thrasher (north), Henslow’s Sparrow (flight call only), and Orchard Oriole.

Although this is a Fall Seasonal Report, noted or suggested breeding activity is of interest. Exciting were the 2nd and 3rd presumed breeding records of Black-chinned Hummingbird and, in Dodge Co, the 5th record of breeding by Black-bellied Whistling-Duck. Perhaps the strangest west to east occurrence was a Golden Eagle adventure in …

Associations Between Feed Efficiency And Feeding Behavior In Yearling Angus Bulls In A Competitive Environment, Amelia Katz

Master's Theses

Feed efficiency in beef cattle is a complex trait shaped by physiological, behavioral, and social factors that influence how animals access and utilize feed resources. This study examined feed efficiency classification and how it is influenced by feeding behavior, competitive interactions, and bunk approach patterns in yearling Angus bulls housed in a drylot over two years. Bulls were grouped into high and low feed efficiency categories using residual feed intake and feed conversion ratio within pen and year (n = 40 per year; n = 40 per treatment). Continuous electronic monitoring quantified feeder visitation, feeding duration, intake, and rate. A …
