Anti-Predator Behavior And Discriminative Abilities: Playback Experiments With Free-Ranging Equatorial Saki Monkeys (Pithecia Aequatorialis) In The Peruvian Amazon, Candace Stenzel

Graduate Theses

Anti-predator behaviors of free-ranging groups of equatorial saki monkeys (Pithecia aequatorialis) were recorded in the Área de Conservación Regional Comunal Tamshiyacu Tahuayo in the Peruvian Amazon to determine whether individuals responded in predator-specific ways to calls of aerial and terrestrial predators. Previous studies have shown that several species of Old World monkeys possess these discriminative abilities, but few have explored this question in New World monkeys. The ability to recognize predators and to respond appropriately is important for survival. Thus, we predicted that equatorial saki monkeys should respond in predator-specific ways, both vocally and behaviorally, to aerial and terrestrial predators. …

Serum Biochemistry Panels In African Buffalo: Defining Reference Intervals And Assessing Variability Across Season, Age And Sex, Johanna Rigas, Claire E. Couch, Morgan A. Movius, Anna E. Jolles, M Elena Gorman, Brianna R. Beechler

Animal, Dairy, and Veterinary Science Faculty Publications

Serum biochemical parameters can be utilized to evaluate the physiological status of an animal, and relate it to the animal’s health. In order to accurately interpret individual animal biochemical results, species-specific reference intervals (RI) must be established. Reference intervals for biochemical parameters differ between species, and physiological differences including reproductive status, nutritional resource availability, disease status, and age affect parameters within the same species. The objectives of this study were to (1) establish RI for biochemical parameters in managed African buffalo (Syncerus caffer), (2) assess the effects of age, sex, pregnancy, and season on serum biochemistry values, and (3) compare …

Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris

Thesis Projects

Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment …

Expanding Access To Biodiversity Literature, Patrick Randall

Digital Initiatives Symposium

Expanding Access to Biodiversity Literature (EABL) is an IMLS-funded grant designed to enhance the collection of the Biodiversity Heritage Library (BHL), a digital library providing open access to over 50 million pages of legacy biodiversity literature.

BHL's collection is built on the digitized holdings of its member libraries, typically large research universities, natural history museums, and other well-funded organizations. EABL, however, solicits content outside the BHL consortium; small organizations that often lack the resources for cataloging and digitization nevertheless have valuable and unique literature to contribute. This has created new challenges for BHL workflows, as well as opportunities for novel …

Population Structure, Connectivity, And Phylogeography Of Two Balistidae With High Potential For Larval Dispersal: Balistes Capriscus And Balistes Vetula, Luca Antoni

Dissertations

The gray triggerfish (Balistes capriscus) and the queen triggerfish (Balistes vetula) are two exploited reef fish distributed in tropical and temperate shelf waters of the Atlantic Ocean and the Mediterranean Sea. Both species are highly sedentary as adults but disperse pelagic larvae for extended periods of time potentially allowing connectivity across long distances under the action of oceanic currents. In this work population structure, phylogeography, and migration patterns were examined in the two species and contrasted with predictions of larval transport based on surface circulation data. A total of 1,017 gray triggerfish from twelve sampling localities …

Species Differences In Egocentric Navigation: The Effect Of Burrowing Ecology On A Spatial Cognitive Trait In Mice, Jason N. Bruck, Noah A. Allen, Kelsey E. Brass, Brian A. Horn, Polly Campbell

Faculty Publications

© 2017 The Association for the Study of Animal Behaviour Efficient navigation is a critical component of fitness for most animals. While most species use a combination of allocentric (external) and egocentric (internal) cues to navigate through their environment, subterranean environments present a unique challenge in that visually mediated allocentric cues are unavailable. The relationship between egocentric spatial cognition and species differences in ecology is surprisingly understudied. We used a maze-learning task to test for differences in egocentric navigation between two closely related species of mice, the eastern house mouse, Mus musculus musculus, and the mound-building mouse, Mus spicilegus. The …

Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420

University Scholar Projects

Advances in technology and availability associated with camera traps have resulted in a rapid rise in their use to monitor wildlife distribution, abundance, and behavior. We focus on assessing body condition, a new application of camera traps. Body condition indices must relate to the percent body fat if they are to be useful. To acquire measurements of body fat, most body condition indices require capture or mortality of animals to estimate, which has limitations when applied to free-ranging animals. We developed a non-invasive, visual body condition index (VBCI) to assess body condition of mule deer that can be applied …

Time-Activity And Energy Budgets Of Eared Grebes (Podiceps Nigricollis) At Salton Sea, Samantha San Francisco

Theses

Time-activity budgets have been a widely accepted way of approximating the daily energy expenditure of many species, including waterbirds. For this study, focal animal sampling was used to study Eared Grebes (Podiceps nigricollis) at their post-wintering stopover site, Salton Sea. Daylight time-activity budgets were converted to energy budgets using energy equivalents for diving, preening, swimming, and resting on water developed for Eared Grebes previously by H. I. Ellis (1994). Post-wintering Eared Grebes arrive at Salton Sea in waves at differing times in the spring. As a result, there can be individuals in a variety of physiological states during …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleukin-8 Receptor Genes Are Related To Production Traits And Hair Coat Score In Crossbred Cattle, Avery Deaton

Animal Science Undergraduate Honors Theses

The objective of this thesis was to identify polymorphisms in the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2) genes and to associate genotypes between the above mentioned polymorphisms and production traits in crossbred cattle. The hypothesis was that polymorphisms will exist for GR and CXCR2 genes and will be linked to production traits. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproduction health, such as protecting the embryo from the maternal immune system during …

The Bovine Rumen Microbiome Revealed By Different Fractions Of Rumen Contents, Ashlee L. Breakstone

Animal Science Undergraduate Honors Theses

The bovine rumen microbiota is very important in terms of animal functionality and digestion. The fermentative capability of the rumen provides means for the digestion of complex plant material that is indigestible by humans. The rumen is the working ground for millions of microorganisms, primarily bacteria, to digest and ferment feed into volatile fatty acids and bacterial protein for the animal’s energy and protein needs, respectively. Of significant importance is the rumen microbiomes ability to conform to certain factors such as genetics, feed, or geographic location. These changes can have a direct measure on animal growth, health, and performance. The …

Predicting The Onset Of Parturition By Determining Calcium In Prepartum Milk Of Sheep, Lensey Watson

Animal Science Undergraduate Honors Theses

Multiple methods of pregnancy detection can be used in sheep production. The gestation period for sheep is usually between 144 and 150 days; however, depending on the breed and age of the ewes, this number can vary. A breeding marker, such as a breeding crayon, is used to detect when the ewe is bred by the ram, and the date the ewe will lamb is typically calculated based on an average 145-day gestation. Unfortunately, this method provides only a rough estimate of when the ewe could lamb. In addition, because sheep routinely give birth to multiples (twins, triplets, and, sometimes, …

Late Quaternary Dragon Lizards (Agamidae: Squamata) From Western Australia, Julie Rej

Electronic Theses and Dissertations

Fossil Agamidae from Western Australia have been the subject of limited study. To aid in fossil agamid identification, Hocknull (2002) examined the maxilla and dentary of several extant species from Australia and determined diagnostic characters for various species groups. In the study here, fossil agamids from two localities in Western Australia, Hastings Cave and Horseshoe Cave, were examined, grouped, and identified to the lowest unambiguous taxonomic level. Morphometric analyses were conducted to compare morphotypes, and find additional diagnostic characters. From Hastings Cave there were two maxilla morphotypes and three dentary morphotypes. Based on identifications, taxa present at this locality were …

Identification Of Molecular Signatures Of Environmental And Nutritional Stress Responses In Poultry, Phuong Hieu Nguyen

Graduate Theses and Dissertations

Poultry production plays an important role in the food supply and security for billions of people. Poultry meat is considered the most efficient, nutritious source of protein, without religious taboos, and is relatively inexpensive. However, the poultry industry is facing substantial challenges. The global environmental temperature has experienced dramatic changes in the last few years. Modern broilers are not well adapted to environmental challenges (heat and cold stress), which have resulted in heavy economic loss in the poultry industry worldwide. In addition, the use of feed restriction regimens in management of breeders as well as the transportation of young chicks …

Phenology, Habitat Use, And The Impacts Of Wetland Management On Autumn Migrating Rails In Missouri, Auriel M.V. Fournier

Graduate Theses and Dissertations

Rails (Family: Rallidae) are among the least studied birds in North America, in large part due to their elusive nature. As a wetland-dependent species, understanding the timing of their migration and their habitat needs during migration is especially important since management needs to be timed to balance the needs of many species. I developed and verified a new distance sampling based nocturnal ATV spotlight survey because traditional call-broadcast surveys are not effective during autumn migration because of the drop off in call rate after the breeding season. These surveys allow us to ask point-level questions about what habitats rails select …

Influence Of Exogenous Phytase Level And Interaction With Supplmental Xylanase On Live Performance And Phosphorus Retention Of Broilers, Peyton Gilbert

Graduate Theses and Dissertations

Two 3-week experiments were conducted, each using 480 day-old male broilers placed randomly among 96 battery cages (5 per cage; 680cm2 per bird), to evaluate the influence of phytase supplementation, with or without supplemental xylanase, on bird performance. Individual body weights and cage feed weights were taken on days 0, 7, 14, and 21, and mean BW, body weight gain (BWG), feed intake (FI), and FCR over each period calculated. Mortality was recorded daily and used to calculate livability and adjust FCR in both trials. In trial 2, excreta was collected by cage from 14 to 21 days for bone …

Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski

School of Natural Resources: Dissertations, Theses, and Student Research

Native rangelands in the Great Plains are largely privately owned and used for beef production. Vegetation heterogeneity is important for maintaining biodiversity, but private land may be more homogenous than desired. My research had two components: 1) to examine whether a variety of grazing strategies created vegetation heterogeneity in a large, intact rangeland, and 2) to understand beef producers’ attitudes about vegetation heterogeneity.

First, I sampled vegetation structure, composition, and bird abundance at multiple plots on eleven management units in Cherry County, Nebraska. Units were managed with commonly used grazing strategies (e.g., short-duration grazing and season-long continuous grazing). I examined …

Capture Theory & State Regulation Of Animal Cruelty, Kyla Henderson

Political Science Theses and Capstones

In this thesis I theorize that regulatory capture impacts animal cruelty laws in several different ways. Capture theory is the process by which regulatory agencies eventually come to be dominated by the industries they were charged with regulating. Regulatory capture happens when a regulatory agency, formed to act in the public’s interest, eventually acts in ways that benefit the industry it is supposed to be regulating, rather than the public. Animal cruelty regulations are an important factor in the way that everyday products are produced. Capture theory affecting animal cruelty is an important look at the growing concern with animal …

Evaluating Habitat-Based Niche Requirements And Potential Recruitment Bottlenecks For Imperiled Bluehead Sucker (Catostomus Discobolus), Bryan C. Maloney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Changes to rivers that alter physical and thermal habitat may cause fish population abundance to decline, due to fewer individuals maturing and entering the adult population. The Weber River has become highly degraded with many dams and diversions altering fish habitat, river volume, velocity, and temperature, and limiting movement between reaches. Bluehead suckers (Catostomus discobolus) occupy only 47% of their historical range and the genetically-distinct Weber River (northern UT) population is declining and contains few young, juvenile fish. My objectives were to determine whether spawning and rearing habitat available in the Weber River may be limiting bluehead sucker …

To What Extent Might Beaver Dam Building Buffer Water Storage Losses Associated With A Declining Snowpack?, Konrad Hafen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dams built by North American Beaver create natural water storage and slow water as it moves through streams. In portions of streams with beaver dams, these effects have been observed to decrease the peak magnitude of floods and increase base flow during annual summer droughts. In the western United States changes to streamflow patterns have been observed in recent decades with large spring floods coming earlier in the year, causing annual summer droughts to start earlier and last longer. These changes are linked to decreasing snowpack which acts as the most significant natural water storage reservoir by holding onto precipitation …

Does Personality Similarity In Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?, Kelsey R. Moreno

Master's Theses

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated …

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …

Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg

Master's Theses

Invasive Red Lionfish (Pterois volitans) were first detected in the northern Gulf of Mexico (nGOM) in 2010 and since then their numbers have increased dramatically. From 2010 to 2015, more than 15,000 Red Lionfish were collected opportunistically from the nGOM for this study. Length and weight relationships differed significantly among ecoregions by sex and there was clear sexual dimorphism in size with males being larger and heavier. Red Lionfish age ranged from 0-4.5 years old and males achieved greater growth rate (K) and asymptotic maximum lengths (L_inf) compared to females and these parameters were also different …

Laterality Preferences Completing A Tool-Use Task In Asian Small-Clawed Otters (Aonyx Cinereus), Stephanie E. James

Honors Theses

Laterality is defined as the occurrence of each cerebral hemisphere having asymmetric control over the different sides of the body, leading to preferences to use one side of the body over the other for various behaviors. Many types of laterality exist, but handedness is the form that is most predominantly assessed. Handedness in animals is of special interest to laterality researchers, as humans were once thought to be the only species that exhibited lateralized hand preferences. The aim of the current study was to determine if Asian small-clawed otters exhibit significant paw preferences in behaviors associated with completing a tool-use …
