Thesis Director: Dr. John Michael Mehaffey
Quarter and Paint horse mares (n= 9) were randomly assigned to 1 of 3 groups after being blocked based by expected conception date. Groups consist of mares on no work (NW), light work (LW), and moderate work (MW). Blood was taken weekly via jugular venipuncture prior to first heat cycle from each mare. Additionally, blood was taken at time of ovulation and then weekly …
Why We Still Need To Worry About Bees, Meaghan Lee Callaghan
Why We Still Need To Worry About Bees, Meaghan Lee Callaghan
Capstones
American honey bees, and other native bee species, are still in decline, though the specter of colony collapse disorder may be fading behind us. Colony decline, the loss of bees overwinter experienced across the country at a quarter to third lost per hive (sometimes more), is now expected. Losses can include those from colony collapse disorder. The author discusses the different causes for colony decline and speaks to bee health scientists and local beekeepers.

Invasive Species Impacts On Infrastructure, Invasive Species Advisory Committee
Invasive Species Impacts On Infrastructure, Invasive Species Advisory Committee
National Invasive Species Council
Executive Summary
Invasive species represent one of the most significant threats to ecosystems, human and animal health, infrastructure, the economy, and cultural resources. Because potentially invasive, non-native species typically enter the United States through ports of entry in urban environments, some of the first observable impacts may be to infrastructure, yet little is known about the economic costs associated with these impacts to the “built” environment. In addition, federal agencies currently lack the authority necessary to effectively prevent, eradicate, and control invasive species that impact the human-built environment. This lack of authority prevents rapid response to some of the most …
The Effect Of Lupinus Albus And Calcium Chloride On Growth Performance, Body Composition, Plasma Biochemistry And Meat Quality Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce P. Mullan, Jae Cheol Kim, Frank R. Dunshea
The Effect Of Lupinus Albus And Calcium Chloride On Growth Performance, Body Composition, Plasma Biochemistry And Meat Quality Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce P. Mullan, Jae Cheol Kim, Frank R. Dunshea
Animal production and livestock research articles
Two hundred and ninety-four pigs were used to assess the effect of two ingredients (Lupinus albus (albus lupins) or a combination of calcium chloride and sodium tri-polyphosphate (mineral salts)) on growth performance, body composition and objective meat quality of pigs immunized against gonadotrophin releasing factor (immunocastrates) and entire male pigs in the late finishing phase. Pigs fed mineral salts ate less feed than those fed the control diet with no effect on growth rate (p > 0.05), backfat (p > 0.05) or fat deposition (p > 0.05). Pigs fed albus lupins had a reduced feed intake (p < 0.001 for all time periods), lower growth rate (p < 0.001 for all time periods), lower backfat (p < 0.005) and decreased fat deposition (p < 0.001 for all time periods) compared to those fed the control diet or mineral salts. From day (d) 0–28 pigs fed mineral salts had a better feed conversion ratio (p = 0.001) than those fed albus lupins who in turn had an improved feed conversion compared to the control diet. Immunocastrates had thicker backfat than entire males at the end of the experiment (p < 0.001), however, feeding albus lupins to immunocastrated males reduced backfat thickness to similar to entire males fed the control diet (p = 0.01). With the exception of the increased muscle pH at 45 min post-exsanguination in mineral salts and albus lupins compared with the control diet (p = 0.03) there was no effect of diet on objective pork quality. Pork from IC males had a higher ultimate pH (p < 0.001), was lighter (L*; p = 0.003), more yellow (p = 0.008) and had a higher drip loss (p < 0.001) compared to entire males. Albus lupins show potential in reducing the increase in feed intake and backfat associated with immunocastration. Mineral salts may be useful in situations where a reduction in feed intake and an improvement in feed conversion is desired and reducing fat deposition is not the objective.
The Power Of Associative Learning And The Ontogeny Of Optimal Behaviour, Magnus Enquist, Johan Lind, Stefano Ghirlanda
The Power Of Associative Learning And The Ontogeny Of Optimal Behaviour, Magnus Enquist, Johan Lind, Stefano Ghirlanda
Publications and Research
Behaving efficiently (optimally or near-optimally) is central to animals’ adaptation to their environment. Much evolutionary biology assumes, implicitly or explicitly, that optimal behavioural strategies are genetically inherited, yet the behaviour of many animals depends crucially on learning. The question of how learning contributes to optimal behaviour is largely open. Here we propose an associative learning model that can learn optimal behaviour in a wide variety of ecologically relevant circumstances. The model learns through chaining, a term introduced by Skinner to indicate learning of behaviour sequences by linking together shorter sequences or single behaviours. Our model formalizes the concept of conditioned …

Pharmacy Faculty Articles and Research
Although primary cilia have been shown to play crucial roles in the development of embryonic mouse heart, their presence and function in adult mouse heart remains controversial. In this study, the presence of primary cilia in adult mouse heart was investigated. The presence of primary cilia was initially demonstrated in the surface of cardiac cells of mouse hearts from both young and adult mice by immunostaining with acetylated α-tubulin, a ciliary structural marker. The presence of cardiac primary cilia in 1-, 3-, 6- and 12-month old mice was further confirmed by staining heart tissues with an antibody against pericentrin, a …
Resource Use Overlap In A Native Grouper And Invasive Lionfish, Joseph Schmidt Curtis
Resource Use Overlap In A Native Grouper And Invasive Lionfish, Joseph Schmidt Curtis
USF Tampa Graduate Theses and Dissertations
Invasive species can severely disrupt biological communities through their interactions with native organisms, yet little is known about the response of marine predators to the establishment of a competitive invasive fish. In the western Atlantic, invasive Indo-Pacific lionfishes (Pterois spp.) may represent a novel competitor to several commercially and ecologically important native species. However, there is a scarcity of empirical research documenting comparative resource use of cohabitant lionfish and native fishes, as well the physiological consequences that may result from interspecific interactions with the invasive species. For this thesis, I conducted two studies designed to elucidate the strength …
Goats Learn Socially From Humans In A Spatial Problem-Solving Task, Christian Nawroth, Luigi Baciadonna, Alan G. Mcelligott
Goats Learn Socially From Humans In A Spatial Problem-Solving Task, Christian Nawroth, Luigi Baciadonna, Alan G. Mcelligott
Social Cognition Collection
Domestication drives changes in animal cognition and behaviour. In particular, the capacity of dogs to socially learn from humans is considered a key outcome of how domestication shaped the canid brain. However, systematic evidence for social learning from humans in other domestic species is lacking and makes general conclusions about how domestication has affected cognitive abilities difficult. We assessed spatial and social problem-solving abilities in goats (Capra hircus) using a detour task, in which food was placed behind an inward or outward V-shaped hurdle. Goats performed better in the outward than in the inward detour without human demonstration. Importantly, a …
Monk Parakeets, Michael L. Avery, James R. Lindsay
Monk Parakeets, Michael L. Avery, James R. Lindsay
Wildlife Damage Management Technical Series
Since their introduction to the United States in the 1960s, monk parakeets (Myiopsitta monachus) have thrived (Figure 1). Until recently, annual Christmas Bird Count data have shown the population to be increasing exponentially. In the U.S., monk parakeets are an urban and suburban species with few natural predators, diseases or other factors limiting their population growth. They exploit backyard bird feeders and non-native ornamental plants for food. Monk parakeets often construct nests on man-made structures, such as electric utility facilities and cell phone towers. Because the birds build and maintain nests throughout the year, management of parakeet populations …

Influence Of Porcine Plasma Supplementation On Gestating Sow Serum Igf-1 Concentration And Litter Weights, Mathew Vaughn, Crystal Serrano, Derris Burnett, Duane Davis, Jason Woodworth, John Gonzalez
Professional Agricultural Workers Journal
The objective of this pilot study was to determine the effect of dietary porcine plasma on circulating insulin-like growth factor 1 (IGF-1) concentrations in gestating sows and characteristics of their litters. Primiparous and multiparous sows were randomly allocated to two treatment groups of sows fed a basal diet or sows fed the basal diet plus 6 g of porcine plasma throughout gestation. On 4 periods during gestation and farrowing, blood was collected for IGF-1 analysis. After farrowing, gestation length, number born, birth weight, and total litter weight were recorded. There were no three-way or two-way interactions between treatments, day of …
Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Emotion Collection
Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

Acetylsalicylic Acid Supplementation Improves Protein Utilization Efficiency While Vitamin E Supplementation Reduces Markers Of The Inflammatory Response In Weaned Pigs Challenged With Enterotoxigenic E. Coli, Jae Cheol Kim, Bruce P. Mullan, John L. Black, Robert J E Hewitt, Robert J. Van Barneveld, John R. Pluske
Animal production and livestock research articles
Background
This experiment was conducted to test the hypothesis that vitamin E (Vit E) and acetylsalicylic acid (ASA), a cyclooxygenase-2 (COX-2) inhibitor, will additively reduce the production of the immunosuppressive molecule prostaglandin E2 (PGE2) and hence reduce inflammatory responses in weaner pigs experimentally infected with an enterotoxigenic strain of E. coli.
Methods
The experiment was conducted in a research facility with 192 individually-housed male weaner pigs (Landrace × Large White) weighing 6.6 ± 0.04 kg (mean ± SEM). The pigs were experimentally infected with an enterotoxigenic strain of E. coli and were allocated to a 2 × 3 factorial …

Resource Quality And Defense: Feeding Behaviors And Female Territoriality In Two Species Of Tropical Hummingbird, Briana Grether
Independent Study Project (ISP) Collection
The study "Resource Quality and Defense: Feeding Behaviors and Female Territoriality in Two Species of Tropical Hummingbird" investigates the feeding behaviors and territoriality of hummingbirds at a flowering shrub of the Gesneriaceae family, Besleria solanoides. Four 1.25-hour observation periods were completed each day, rotating between four different observation sites. During each observation period, the sugar concentration of nectar and number of flowers on each bush was measured, and each time a hummingbird entered the area the following data was recorded: species, sex, time of arrival, duration of visit, number of flowers probed, number of perches, duration of longest perches, any …
The Development Of A Reproductive Population Of Chorongos: Intergroup Interactions, Dispersal, And Sexual Behavior Of Lagothrix Lagotricha Poeppigii In Natural Rehabilitation On The Island Of Sumak Allpa, Ecuador, Rachel Gallegos
Independent Study Project (ISP) Collection
The lowland woolly monkey (Lagothrix lagotricha poeppigii) is vulnerable due to various human pressures, as they are especially sensitive to stress and habitat degradation. Due to their low rate of success in captivity, the few institutions that have tried to create and maintain breeding populations for conservation purposes are no longer able or willing to do so. Sumak Allpa, an NGO in the Orellana province of the Ecuadorian Amazon, currently has the only repopulation project in Ecuador with the long-term goal of maintaining a reproductive population and releasing groups of woolly monkeys back into the wild. In a …
Humanity Balancing On A Turtle’S Back: Perceptions And Values Of Sea Turtle Conservation Among Different Demographics At Four Sites In The Bocas Del Toro Archipelago Bocas Del Toro, Panama, Roxanne Hoorn
Independent Study Project (ISP) Collection
Being the ancient, world traveling, iconic mega-fauna they are, sea turtles have found their way into cultures and traditions around the world, often holding great prestige. Along with their mystical qualities, sea turtles have also been intricately intertwined in the livelihoods of cultures around the globe, utilized for food, jewelry, income, and more recently, scientific research. The ways in which humans around the world perceive the value of this species varies greatly, often causing conflict between those who wish to protect and conserve sea turtles, and those looking to continue using turtles as either a source of income or food. …

Reef Fish And Coral Assemblages On Hospital Point And Near Bastimentos Island, Panama, Elaine Shen
Independent Study Project (ISP) Collection
Because worldwide declines coral reef health are of major concern, studying coral reefs through the lens of conservation efforts at local scales is essential for determining and monitoring effective policy measures. In the Bocas del Toro Archipelago, there are conflicts of interest between exploitative rapid tourism development, overfishing practices, and national efforts to conserve the local marine biodiversity. Coral and reef fish species abundance richness, diversity, evenness, and similarity were measured to see how coral and reef fish assemblages changed between protected and unprotected areas. A total of 329 fish and 322.5 square meters of benthos were analyzed using underwater …
Evaluating A Squirrel Monkey Troop In Natural Rehabilitation: An Assessment Of Population And Behavior Of Saimiri Sciureus In Preparation For Relocation From Sumak Allpa To Yasuní National Park, Bria Riggs
Independent Study Project (ISP) Collection
Natural rehabilitation and translocation of primate species provide the opportunity for recovery of individuals and repopulation of species in the wild. However, there are few successful examples of primate translocation around the world, and no successful cases in Ecuador. This study assesses the population and overall behavioral activity of a troop of Saimiri sciureus on Sumak Allpa Island, Orellana, Ecuador from November 6th to November 27th, 2016. This specific troop, referred to as the Yasuní troop, is scheduled to be translocated from Sumak Allpa to Yasuní National Park in March or April of 2017, and would be …
Cedar Waxwings, Michael L. Avery, Anthony G. Duffiney
Cedar Waxwings, Michael L. Avery, Anthony G. Duffiney
Wildlife Damage Management Technical Series
Prevention and control of cedar waxwing (Bombycilla cedrorum) damage to small fruits such as blueberry, cherry, and strawberry is vexing to growers in many parts of the United States. Cedar waxwings (Figure 1) travel in flocks and descend in large numbers on berry crops, especially during winter and migration. In short feeding bouts, waxwings eat, peck, or knock substantial amounts of fruit from the plants. These frugivores are difficult to discourage once they become established at a given location. Harassment early and often using pyrotechnics or other sudden noisemakers can help prevent flocks from being established. The most effective preventative …
The Role Of Individual Cognitive And Behavioral Ontogeny In Organization And Evolution Of Social Systems, Andrew G. Fulmer
The Role Of Individual Cognitive And Behavioral Ontogeny In Organization And Evolution Of Social Systems, Andrew G. Fulmer
Dissertations, Theses, and Capstone Projects
Exploration and explanation of the relationship between individual variation in behavior and the composition and adaptive success of social groups or populations are crucial problems in the fields of behavioral ecology, ethology, and comparative psychology. These questions have been the subject of a longstanding discussion at both the proximate and ultimate levels of inquiry. Adaptive mechanisms explaining social decision making, both in terms of affiliative and competitive partner choices, are at the center of such discussions. Inclusive fitness, kin-selection, handicap or prestige, risk seeking and risk avoiding strategies, pay-to-stay/reward principles, as well as other theories have been proposed and supported …
Vegetarian Versus Meat-Based Diets For Companion Animals, Andrew Knight, Madelaine Leitsberger
Vegetarian Versus Meat-Based Diets For Companion Animals, Andrew Knight, Madelaine Leitsberger
Nutrition Collection
Companion animal owners are increasingly concerned about the links between degenerative health conditions, farm animal welfare problems, environmental degradation, fertilizers and herbicides, climate change, and causative factors; such as animal farming and the consumption of animal products. Accordingly, many owners are increasingly interested in vegetarian diets for themselves and their companion animals. However, are vegetarian canine and feline diets nutritious and safe? Four studies assessing the nutritional soundness of these diets were reviewed, and manufacturer responses to the most recent studies are provided. Additional reviewed studies examined the nutritional soundness of commercial meat-based diets and the health status of cats …

MANTER: Journal of Parasite Biodiversity
Anthropocommensal rodents live in close proximity to humans in many habitats around the world. They are a threat to public health because of the pathogens they carry. Recent studies in Mérida, Yucatán, México, have shown that commensal rodents harbor potential zoonotic pathogens such as bacteria, helminths, and viruses. In this study, we describe reproductive and demographic parameters of house mice and black rats present in households from Mérida, Yucatán, México, a municipality located in a tropical region in southern México. Rodents were trapped in 142 households within the municipality of Mérida from 2011 to 2014. A total of 832 rodents …

HUMANS AND DOGS have a long, wonderful and sometimes problematic association. At a personal level, dogs have been integral to our lives, and our parents’ lives, for as long as the two of us can remember. As sociologists, we also recognize that dogs are important at the macro level. Here, we introduce a selection of early sociological arguments about dogs and their social relationships with humankind. Our interest in developing this book began when we encountered the delightful essays on dogs by Charlotte Perkins Gilman and Annie Marion MacLean — two insightful Anglo-American sociologists who present opposing sympathies regarding the …

Orca Behavior And Subsequent Aggression Associated With Oceanarium Confinement, Robert Anderson, Robyn Waayers, Andrew Knight
Theory of Mind Collection
Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may apply, or in captivity, where access is constrained for commercial and safety reasons. From 1979 to 1980, however, we were able to interact with juvenile orcas in an unstructured way at San Diego’s SeaWorld facility. We observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, …
Effects Of An Electronic, Motion-Activated Scarecrow On Foraging Time In Nocturnal Vertebrate Crop Pets In South Africa, Mallory Clouse
Effects Of An Electronic, Motion-Activated Scarecrow On Foraging Time In Nocturnal Vertebrate Crop Pets In South Africa, Mallory Clouse
Mahurin Honors College Capstone Experience/Thesis Projects
The normal behaviors of animals can disrupt human activities, resulting in human wildlifeconflict. In South Africa, nocturnal crop raiders are a significant source of human wildlifeconflict for farmers. Major nocturnal pest animals are Cape porcupine (Hystrix africaeaustralis) and bushpig (Potamochoerus larvatus). Although methods of deterring animals from agricultural areas have been explored, nocturnal crop raiding remains difficult to mitigate. Most research studies focus on deterring non-human primates and elephants, but methods that may be successful in deterring such larger mammals are not necessarily effective at discouraging smaller, nocturnal crop raiders. This study examined the efficacy of …

German Shepherd Dogs are important in police and military work, and are a popular family pet. The debilitating joint disorders of hip dysplasia, cranial cruciate ligament tear (CCL) and elbow dysplasia can shorten a dog’s useful working life and impact its role as a family member. For this study, veterinary hospital records were examined over a 14.5-year period on 1170 intact and neutered (including spaying) German Shepherd Dogs for joint disorders and cancers previously associated with neutering. The diseases were followed through 8 years of age, with the exception of mammary cancer (MC) in females that was followed through 11 …

Physiology Collection
Dairy cows undergo significant metabolic and endocrine changes during the transition from pregnancy to lactation, and impaired insulin action influences nutrient partitioning toward the fetus and the mammary gland. Because impaired insulin action during transition is thought to be related to elevated body condition and body fat mobilization, we hypothesized that over-conditioned cows with excessive body fat mobilization around calving may have impaired insulin metabolism compared with cows with low fat mobilization. Nineteen dairy cows were grouped according to their average concentration of total liver fat (LFC) after calving in low [LLFC; LFC <24% total fat/dry matter (DM); n = 9] and high (HLFC; LFC >24.4% total fat/DM; n = 10) fat-mobilizing …24%>

Double-Crested Cormorants, Brian S. Dorr, Kristi L. Sullivan, Paul D. Curtis, Richard Chipman, Russell D. Mccullough
Wildlife Damage Management Technical Series
The history of conflict between double-crested cormorants (Figure 1) and human interest in fisheries is long and convoluted. Following a low point in the 1970s, populations of cormorants expanded in North America, as did concerns about impacts on fisheries. By the late 1990s, natural resource agencies in 27 states reported losses of free-ranging fish stocks to cormorants. Agencies in 10 states, ranging from the Southwest to the Northeast, considered cormorant predation to be of moderate to major concern to fishery management.
Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific …

Bird Dispersal Techniques, Thomas W. Seamans, Allen L. Gosser
Wildlife Damage Management Technical Series
Conflicts between humans and birds likely have existed since agricultural practices began. Paintings from ancient Greek, Egyptian, and Roman civilizations depict birds attacking crops. In Great Britain, recording of efforts at reducing bird damage began in the 1400s, with books on bird control written in the 1600s. Even so, the problem persists. Avian damage to crops remains an issue today, but we also are concerned with damage to homes, businesses, and aircraft, and the possibility of disease transmission from birds to humans or livestock. Successful dispersal techniques should capitalize on bird sensory capabilities. If birds cannot perceive the dispersal technique, …
