Dialect Use Within A Socially Fluid Group Of Southern Resident Killer Whales, Orcinus Orca, Courtney Elizabeth Smith
Dialect Use Within A Socially Fluid Group Of Southern Resident Killer Whales, Orcinus Orca, Courtney Elizabeth Smith
Master's Theses
Resident killer whales, Orcinus orca, of the Northeastern Pacific form stable kinship-based matrifocal associations and communicate with group-specific repertoires of discrete calls (dialects) that reflect these associations. The gradual fission of matrilines is usually consistent with dialect variations among groups that may manifest as differences in call usage at the repertoire level or subtle structural differences of the calls themselves. Therefore, matrilines that are more closely related tend to be more acoustically similar. Within the endangered community of Southern Resident killer whales (SRKWs), recent evidence shows that one particular group (L pod) exhibits the lowest rate of intrapod association …
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Graduate Theses and Dissertations
Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …
The Role Of Adiponectin And The Adipocyte In Energy Metabolism And Inflammation, Sheila Kay Jacobi
The Role Of Adiponectin And The Adipocyte In Energy Metabolism And Inflammation, Sheila Kay Jacobi
Open Access Dissertations
A series of experiments were conducted to characterize the autocrine role of adiponectin in modulating fatty acid metabolism and inflammation in the pig. In the first study, we cloned and sequenced the porcine adiponectin open reading frame and evaluated the regulation of adiponectin, in vitro and in vivo. The porcine sequence shares approximately 88, 86, 85 and 83% homology with the dog, human, cow and mouse adiponectin, respectively, and 79–83% similarity with dog, human, cow and mouse proteins at the amino acid level, based on the translated porcine sequence and GenBank submissions for the other species. Analysis of serum from …
Regulatory Capture, The Chesapeake Bay, And Hampton Roads: What's On Your Plate, Ronnie David Gannon
Regulatory Capture, The Chesapeake Bay, And Hampton Roads: What's On Your Plate, Ronnie David Gannon
Institute for the Humanities Theses
The Chesapeake Bay and its 64,000 square mile watershed are both severely impacted from excessive amounts of nutrient pollution, which contributes to a growing presence of dead zones in the Bay. What causes nutrient pollution? What are dead zones? In addition, many of the Bay's commercially valuable species of marine life have been/ are overexploited to the point of collapse / verge of collapse. Despite all of these facts, management agencies continue to weakly enforce regulations. Why?
Not to mention, much of the Bay's marine life is unsustainably caught in the contaminated waters of Hampton Roads. How, and for what? …
Habitat Preferences Of The Common Nighthawk (Chordeiles Minor) In Cities And Villages In Southeastern Wisconsin, Jana M. Viel
Habitat Preferences Of The Common Nighthawk (Chordeiles Minor) In Cities And Villages In Southeastern Wisconsin, Jana M. Viel
Theses and Dissertations
Limited survey data and numerous anecdotal accounts indicate that the Common Nighthawk (Chordeiles minor) is experiencing population declines in Wisconsin. However, the magnitude of the decline is unclear because current avian monitoring efforts are not conducted at dusk when Common Nighthawks are most active nor do they specifically target urban areas such as cities and villages where Common Nighthawks are known to nest on flat graveled rooftops. New urban, crepuscular monitoring methods are needed in order to gain a better understanding of current Common Nighthawk demographics in Wisconsin.
The goal of this thesis was to conduct a baseline study using …
Evaluation Of The Functional Capabilities Of Fins And Limbs For Moving On Land: Insights Into The Invasion Of Land By Tetrapods, Sandy Kawano
All Dissertations
Transitions to novel habitats present different adaptive challenges, producing captivating examples of how functional innovations of the musculoskeletal system influence phenotypic divergence and adaptive radiations. One intriguing example is the transition from aquatic fishes to tetrapods. Recent technological advances and discoveries of critical fossils have catapulted our understanding on how fishes gave rise to terrestrial vertebrates. Considerable attention has been paid to legged locomotion on land, but given that the first tetrapods were aquatic, limbs did not evolve primarily for terrestriality. How, then, is the locomotor function of limbs different from fins? Extant amphibious fishes demonstrate that fins can be …
Effects Of Animal Management Changes On The Activity Budgets And Walking Rates Of Zoo Elephants, Angela Dawn Mackey
Effects Of Animal Management Changes On The Activity Budgets And Walking Rates Of Zoo Elephants, Angela Dawn Mackey
Dissertations
The current study aimed to assess the effects of two management strategies, weekly rototilling of the enclosure and the provision of unpredictable foraging opportunities, on the daily behavior of six elephants housed at the San Diego Zoo. Observations took place from January to June 2013 and were conducted throughout a 24- hour period. The study was divided into three phases, each two months in duration. During the first phase (baseline) no changes were made to the current management routine of the elephants. In Phase 2, rototilling of the elephant enclosures was increased from once monthly to once per week, while …
Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch
Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch
Open Access Theses
Past studies on the communication systems of species in urban environments (such as Common Starlings (Sturnus vulgaris), nightingales (Luscinia megarhynchos Brehm), brown-headed cowbirds ( Molothrus ater), Southern brown tree frogs (Litoria ewingii )) have shown multiple ways that species change vocal signaling behavior to adjust to urban habitats (e.g. alarm calls and singing). This study further investigates the changes in signaling in relation to the chick-a-dee call of the Carolina chickadee (Poecile carolinensis). A secondary goal of this study was to compare both the amount of information and rate of calling across …
Choice And Control Of Enrichment For A Rescued And Rehabilitated Atlantic Bottlenose Dolphin (Tursiops Trunactus), Hannah Bahe
Choice And Control Of Enrichment For A Rescued And Rehabilitated Atlantic Bottlenose Dolphin (Tursiops Trunactus), Hannah Bahe
Honors Theses
Animals living under human care experience stress related to a lack of control over t environment. One way to remedy this is through the use of cognitive enrichment, su choice and control of enrichment. This type of enrichment has been shown to have benefits for animals under human care including increased activity and social interactions. To determine if choice and control was more beneficial than enrichmen alone, a three year old male Atlantic bottlenose dolphin (Tursiops truncatus) was ex to novel enrichment items in two experimental conditions. For the first condition, th animal was given a novel object. During the …

This project seeks to improve salmonid habitat quality by improving riparian vegetation on the adjacent banks (from toe to terrace) on the Chocolay River in Michigan's Upper Peninsula. Quantities of large woody debris (LWD) were also analyzed to determine the heterogeneityof stream habitats, or channel roughness. Percentages of rock, gravel, sand, and silt were analyzed to determine spawning habitat quality. As the proportions of fines (
Genetic Canine Agression, Isabella O'Toole
Genetic Canine Agression, Isabella O'Toole
Thinking Matters Symposium Archive
Canine aggression can pose a serious concern for public and animal welfare. Most of what we know about aggression comes from bite statistics, expert opinions and breed-specific aggressiveness. These sources can often be misleading due to biases toward large or powerful breeds. In this review, I will examine a study that suggest a small number of genes control aggression.

Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp
Theses and Dissertations--Animal and Food Sciences
Lameness and mastitis are the two most costly diseases in the dairy industry. Reduction of these diseases through housing and management is beneficial. Compost bedded pack (CBP) and sand freestall barns were compared in a long-term, on-farm study to assess the effect of housing on each disease. Another research objective was to evaluate the effects of ambient weather conditions on moisture and 20 cm internal temperature of CBP. Compost bedded pack moisture, C:N ratio, and internal temperature effects on cleanliness, mastitis, and bedding bacterial counts were also considered. The last research objective was to evaluate the economics of bedding material …

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin
The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin
Honors Theses
The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England’s …
