Department of Animal Science: Faculty Publications

We assessed the effects of chilled water cooling perches on hen performance and physiological and behavioral parameters under “natural” high temperatures during the 2013 summer with a 4-hour acute heating episode. White Leghorns at 16 wk of age (N = 162) were randomly assigned to 18 cages (n = 9) arranged into 3 units. Each unit was assigned to one of the 3 treatments through 32 wk of age: 1) cooled perches, 2) air perches, and 3) no perches. Chilled water (10◦C) was circulated through the cooled perches when cage ambient temperature exceeded 25^◦C. At the age of …

Finding The Beat: From Socially Coordinated Vocalizations In Songbirds To Rhythmic Entrainment In Humans, Jonathan I. Benichov, Eitan Globerson, Ofer Tchernichovski

Publications and Research

Humans and oscine songbirds share the rare capacity for vocal learning. Songbirds have the ability to acquire songs and calls of various rhythms through imitation. In several species, birds can even coordinate the timing of their vocalizations with other individuals in duets that are synchronized with millisecond-accuracy. It is not known, however, if songbirds can perceive rhythms holistically nor if they are capable of spontaneous entrainment to complex rhythms, in a manner similar to humans. Here we review emerging evidence from studies of rhythm generation and vocal coordination across songbirds and humans. In particular, recently developed experimental methods have revealed …

There exists much misinformation about antibiotic and vaccine use. An understanding of these topics is important for the use of these tools for the best equine health outcomes. The purpose of this study was to evaluate students’ understanding of antibiotics and vaccines, identify learned misinformation, and establish baseline data. A survey was administered at the beginning of Equine Health & Disease (AS 213) and Horse Production (AS 365) at South Dakota State University during the spring 2016 semester. AS 213 is not a prerequisite for AS 365. Results of the survey suggest that students may come with some understanding of …

Nesting Ecology Of The Northern Beardless-Tyrannulet (Camptostoma Imberbe) In The Lower Rio Grande Valley Of Texas, Usa, Scott M. Werner, Sallie J. Hejl, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

During 2002–2003, we studied the breeding ecology of the Northern Beardless-Tyrannulet (Camptostoma imberbe), a poorly known and rare permanent resident in the Lower Rio Grande Valley of Texas, United States of America. We found 28 nests in clusters of Spanish moss (Tillandsia usneoides) or ball moss (T. recurvata), 93% of which were in cedar elm (Ulmus crassifolia) trees. Nest-building, incubation, and nestling periods averaged 7.0, 14.0, and 18.5 days, respectively. Of the 28 nests, 43% were successful, while 38% of the failed nests showed obvious signs of depredation. Nests were located in …

This report provides a comprehensive overview of the Western Australian silver-lipped pearling (Pinctada maxima) industry and the outcomes from the 2015 ecological risk assessment of this industry. The P. maxima pearling industry has been operating in Western Australia since the 1880s, initially harvesting pearl oysters for mother-of-pearl production.

Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan

Master's Theses

Poor rehydration properties of skim milk powder (SMP) can impact processing efficiency and functionality in finished product applications. Rehydration can be split into four stages: wettability, sinkability, dispersibility, and solubility. Previous work has suggested that chelator addition during SMP manufacture leads to higher solubility compared to SMP without chelators. This study focuses on the addition of ethylene diamine tetraacetic acid (EDTA) or sodium citrate dihydrate (SCD) at concentrations of 5, 10, and 15 mM to skim milk prior to evaporating and spray drying. The objective of this investigation was to determine the effects of the chelator additions on each SMP …

Why Come Back Home? Investigating The Proximate Factors That Influence Natal Philopatry In Migratory Passerines, Jenna A. Cava, Noah G. Perlut, Steven E. Travis

Environmental Studies Faculty Publications

Knowledge of which cues attract birds back to natal areas is important for conservation because the cues could be manipulated to attract breeders to source habitat or discourage breeders from settling in sink habitat. We examined the influence of intrinsic and extrinsic variables on natal philopatry using two metrics, short-distance natal dispersal and the probability of philopatry to the natal field, in two obligate-grassland bird species breeding in an agricultural landscape: the bobolink, Dolichonyx oryzivorus, and the Savannah sparrow, Passerculus sandwichensis. During 2002–2014, we detected 90 locally hatched Savannah sparrows and 129 locally hatched bobolinks breeding as adults …

The Mute Swan In Nebraska: History And Current Status, Mark A. Brogie

Nebraska Bird Review

Mute Swans (Cygnus alar) were introduced into North America during the late 1800s as decorative waterfowl and have established feral populations (Ciaranca et al. 1997). Currently, the range of wild populations of Mute Swans in North America includes the Atlantic Coast from Maine to South Carolina and the Great Lakes, with the exception of Lake Superior where it is not established (Baldassarre 2014). The current total North American population is estimated to be 22,000–25,000 (Baldassarre 2014), and populations continue to increase (Petrie and Francis 2003). Indeed, the growing concern over burgeoning numbers has resulted in many states and …

Gyrfalcon In Boyd County, Nebraska, Mark A. Brogie, David Heidt

Nebraska Bird Review

Gyrfalcon (Falco rusticolus) is considered in Nebraska to be a "rare casual winter visitor statewide" (Sharpe et al. 2001). Since 1990, there has been only one NOURC (Nebraska Ornithologists' Union Records Committee) accepted record (Class III) for Gyrfalcon in Nebraska (Jorgensen 2003). This bird was a gray morph adult observed below Keystone Dam, Keith Co., 01 January 2001 (Silcock 2001). Nebraska has no April dates for Gyrfalcon, although South Dakota has several April records: 10 Apr 2001, Jones Co., and 23 Apr 1955, Pennington Co., (Tallman et al. 2002). Additionally, an immature Gyrfalcon was photographed 5 April 2010 …

The Second Nebraska Breeding Bird Atlas, Wayne J. Mollhoff, Bulletin Of The University Of Nebraska State Museum, Vol. 29, 2016 [Book Review], W. Ross Silcock

Nebraska Bird Review

As suggested by its title, this book (“Second Atlas”) presents the results of a follow-up to the first Nebraska breeding bird atlas, The Nebraska Breeding Bird Atlas 1984–89 (“First Atlas”), also authored by Wayne Mollhoff. In this Second Atlas, Mollhoff acknowledges the foresight of John J. Dinan, Nongame Bird Program Manager at Nebraska Game and Parks Commission during the time of the First Atlas, in working toward a “follow-up project.” As Mollhoff says in the foreword to the Second Atlas, "His persistence in pursuing that goal ultimately led to the current project.”

The best feature of the Second Atlas is …

Low Permeability Triple-Layer Plastic Bags Prevent Losses Of Maize Caused By Insects In Rural On-Farm Stores, Jeremiah Ng’Ang’A, Christopher Mutungi, Samuel M. Imathiu, Hippolyte Affognon

All Peer-Reviewed Publications

Participatory on-farm trials were conducted to assess effectiveness of Purdue Improved Crop Storage (PICS™) bags for storage of maize in small-scale farmers’ stores in rural villages in eastern Kenya. A PICS bag is a three-layered hermetic bag-system that forms a barrier against the influx of oxygen and the escape of carbon dioxide. Jute, woven polypropylene or PICS bags were filled with shelled maize grain, purchased from the participating farmers, and the three sets of bags kept in the farmers’ own stores for 35 weeks. Oxygen and carbon dioxide levels in the PICS bags were monitored, as well as the temperature …

Scientifically Defensible Fish Conservation And Recovery Plans: Addressing Diffuse Threats And Developing Rigorous Adaptive Management Plans, Kathleen G. Maas-Hebner, Carl B. Schreck, Robert M. Hughes, J. Alan Yeakley, Nancy Molina

Environmental Science and Management Faculty Publications and Presentations

We discuss the importance of addressing diffuse threats to long-term species and habitat viability in fish conservation and recovery planning. In the Pacific Northwest, USA, salmonid management plans have typically focused on degraded freshwater habitat, dams, fish passage, harvest rates, and hatchery releases. However, such plans inadequately address threats related to human population and economic growth, intra- and interspecific competition, and changes in climate, ocean, and estuarine conditions. Based on reviews conducted on eight conservation and/or recovery plans, we found that though threats resulting from such changes are difficult to model and/or predict, they are especially important for wide-ranging diadromous …

BioResource and Agricultural Engineering

This Senior Project discusses the design, cost analysis, and evaluation of an aquaponics system. The system incorporates aquaculture and hydroponics to create a source of fish protein and various crops. The system was sized based off a minimum requirement of pounds of fish available per week. The system designed is capable of generating 2080 pounds of catfish, and 16,000 pounds of produce annually. The first year of operation the system will operate at a loss due to the significant cost of the components of the system, however, the project is projected to generate a minimum stream of revenue of $10,600 …

Comparison Of Foaming Properties Between Chelated Reconstituted Smp And Caseinates, Boya Liu

Master's Theses

Caseinate powders have been well accepted because of their foaming properties. In this study, 10% solution of reconstituted skim milk powder (SMP) chelated with sodium hexametaphosphate (SHMP) and trisodium citrate (TSC) at 1 mEq, 50 mEq, and 100 mEq were prepared to conduct a comparison with sodium caseinate, potassium caseinate, and calcium caseinate solutions. Foamability, foam stability as well as the preferential locations of αs-casein, β-casein and !-casein in their foams were analyzed. It was hypothesized that the foamability, foam stability and the preferential locations of these three caseins in the milk foams are different from treatment to treatment. Milk …

Spring Field Report, March 2016 To May 2016, W. Ross Silcock

Nebraska Bird Review

In contrast to the fairly routine spring of 2015, this year saw an almost unbelievable parade of early arrivals. About 49 species, including virtually all taxonomic groups, had arrival dates at the early end of expected arrival dates, and a few species set record early dates. Notable early birds were Calidris shorebirds, flycatchers, and swallows, species which depend on available insect and pond-edge life, suggesting that organisms are "waking up" earlier than in previous years, helped, of course, by the mild 2015–2016 winter. On the other hand, there was only one late species: Purple Finch, which remained into mid-May at …

Influencing Pathways That Cause Metastasis And Stemness In Epithelial Ovarian Cancer, Alyse Lynn Huisken-Hill

Electronic Theses, Projects, and Dissertations

Ovarian cancer is the fifth leading cause of cancer death in women between the ages of 35 and 74. With 22 thousand new cases and 15 thousand deaths annually ovarian cancer is among the most deadly cancers with a death to incidence ratio of 68%. With 70% of cases High Grade Serous Ovarian Carcinoma (HGSOC) is the most common type of ovarian cancer and causes 90% of ovarian cancer deaths. 80% of patients have reoccurrence within five years and only 15-30% of patients with recurrent metastatic ovarian cancer respond to current therapies, chemotherapy and surgery. One reason for the high …

Dynamic Egg Color Mimicry, Daniel Hanley, Michael Sulc, Patricia L. R. Brennan, Mark E. Hauber, Tomas Grim, Marcel Honza

Publications and Research

Evolutionary hypotheses regarding the function of eggshell phenotypes, from solar protection through mimicry, have implicitly assumed that eggshell appearance remains static throughout the laying and incubation periods. However, recent research demonstrates that egg coloration changes over relatively short, biologically relevant timescales. Here, we provide the first evidence that such changes impact brood parasite–host eggshell color mimicry during the incubation stage. First, we use long-term data to establish how rapidly the Acrocephalus arundinaceus Linnaeus (great reed warbler) responded to natural parasitic eggs laid by the Cuculus canorus Linnaeus (common cuckoo). Most hosts rejected parasitic eggs just prior to clutch completion, but …

Rescuing Perishable Neuroanatomical Information From A Threatened Biodiversity Hotspot: Remote Field Methods For Brain Tissue Preservation Validated By Cytoarchitectonic Analysis, Immunohistochemistry, And X-Ray Microcomputed Tomography, Daniel Hughes, Ellen Walker, Paul Gignac, Anais Martinez, Kenichiro Negishi, Carl Lieb, Eli Greenbaum, Arshad Khan

There is a need to accelerate collection efforts in these regionsbefore threatened or endangered species become extinct. The diverse geographical, ecological,genetic, morphological, and behavioral data generated from the on-site collection ofan individual specimen are useful for many scientific purposes. However, traditional methodsfor specimen preparation in the field do not permit researchers to retrieve neuroanatomicaldata, disregarding potentially useful data for increasing our understanding of braindiversity. These data have helped clarify brain evolution, deciphered relationships betweenstructure and function, and revealed constraints and selective pressures that provide contextabout the evolution …
