Stable Isotope Analysis (Delta Nitrogen-15 And Delta Carbon-13) And Bioenergetic Modeling Of Spatial-Temporal Foraging Patterns And Consumption Dynamics In Brown And Rainbow Trout Populations Within Catch-And-Release Areas Of Arkansas Tailwaters, Jon M. Flinders

Graduate Theses and Dissertations

I examined spatial and temporal consumption dynamics using an energy intake model and a bioenergetics model of rainbow trout, Oncorhynchus mykiss, and brown trout, Salmo trutta, within three catch-and-release (C-R) areas in Bull Shoals and Norfork tailwaters to determine whether trout populations were limited by food supply. I also examined the seasonal and ontogenetic shifts in the foraging patterns of brown and rainbow trout within these areas using gut content analysis (GCA) and stable isotope analysis (SIA) of C and N. I examined 605 brown trout and 768 rainbow trout for GCA and SIA at Bull Shoals, Norfork, …

Impact Of Different Handling Styles (Good Vs. Aversive) On Growth Performance, Behavior, And Cortisol Concentrations In Beef Cattle, Joan Bauer

Animal Science Undergraduate Honors Theses

Our objective was to determine effects of aggressive handling on growth performance, behavior, and cortisol concentrations in beef calves. Crossbred calves (313 ± 4.7 kg; n = 54; 24 steers, 30 heifers) from a single herd were stratified by gender, body weight, and initial chute score, then allocated randomly to 1 of 6 pens. Each pen was randomly assigned to 1 of 2 handling treatments (good or adverse) applied on days 7, 35, 63, and 91. The objective of good treatment was to handle the calves quietly and gently to minimize stress. The objective of adverse treatment was to move …

A Spatially Explicit Agent Based Model Of Muscovy Duck Home Range Behavior, James Howard Anderson

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Research in GIScience has identified agent-based simulation methodologies as effective in the study of complex adaptive spatial systems (CASS). CASS are characterized by the emergent nature of their spatial expressions and by the changing relationships between their constituent variables and how those variables act on the system's spatial expression over time. Here, emergence refers to a CASS property where small-scale, individual action results in macroscopic or system-level patterns over time. This research develops and executes a spatially-explicit agent based model of Muscovy Duck home range behavior. Muscovy duck home range behavior is regarded as a complex adaptive spatial system …

Social Effects On Vocal Ontogeny In An Ungulate, The Goat, Capra Hircus, Elodie F. Briefer, Alan G. Mcelligott

Sentience Collection

Vocal plasticity is the ability of an individual to modify its vocalizations according to its environment. Humans benefit from an extreme form of vocal plasticity, allowing us to produce a wide range of sounds. This capacity to modify sounds has been shown in three bird orders and in a few nonhuman mammal species, all characterized by complex vocal communication systems. In other mammals, there is no evidence for a social impact on vocal development. We investigated whether contact calls were affected by social environment and kinship during early ontogeny in goats, a highly vocal and social species. To test the …

The Effect Of Neutering On The Risk Of Urinary Incontinence In Bitches – A Systematic Review, W. Beauvais, J. M. Cardwell, D. C. Brodbelt

Endocrinology Collection

An increased risk of urinary incontinence in bitches has often been associated with previous ovariohysterectomy but remains controversial. The objective of this study was to evaluate the strength of evidence for an association between neutering or age at neutering and urinary incontinence in bitches and to estimate the magnitude of any effect found. A systematic review of peer‐reviewed original English analytic journal articles was conducted, based on Cochrane guidelines (Higgins and Green 2009) Of 1,853 records screened, seven studies were identified that examined the effect of neutering or age at neutering on the risk of urinary incontinence but …

Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

We evaluated the reproductive biology of314 white-tailed jackrabbits (Lepus townsendii) in 44 counties throughout South Dakota from June 2004 to September 2005. We classified jackrabbits as juveniles or adults based on the closure of the proximal epiphysis of the humerus using X-ray analysis. We determined annual reproductive activity through fluctuations in measured weights of reproductive organs for both sexes. The 2005 breeding season started in late February and proceeded until mid-July, approximately 142 days, allowing for females to potentially produce 3.3 litters. We found four distinct breeding periods by the overlap of estimated conception and parturition dates. Mean …

A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …

Utilization Of Corn Residue, Winter Range, Or Dry Lot In Beef Heifer Development Systems, Stetson P. Weber

Department of Animal Science: Dissertations, Theses, and Student Research

Post-weaning heifer development systems that maximize reproductive efficiency and reduce input costs associated with feed is beneficial for cow/calf producers. Two research experiments were conducted to evaluate the effect of post-weaning development systems in beef heifers. In Exp. 1 heifers were developed on corn residue (CR), or dry lot (DL). Heifers developed in DL had increased BW after winter treatment until breeding. Both heifer groups were similar in percent of heifers cycling, AI conception, AI pregnancy, and final pregnancy diagnosis. A subset of AI pregnant heifers were blocked by weight and stratified by winter development system and individually fed using …

Effect Of Light Level On Feeding Behavior In A Lemur Species (Eulemur Rubriventer) With A Color Vision Polymorphism., Ainsley Lockhart

Independent Study Project (ISP) Collection

Understanding the visual capabilities and correlated behavior of prosimians provides vital information regarding the evolution of color vision. Feeding behavior in particular is often modified based on color vision status in various primate taxa. The present study examined feeding behavior under various light conditions in Eulemur rubriventer, a lemur species with a color vision polymorphism in which only females can have trichromatic vision. Behavioral observations were conducted for a single E. rubrventer group over a 13 day study period in April 2012. Results found no significant difference in rates of frugivory or exploitation of green vs. non-green food between male …

Tool Use In Fishes, Culum Brown

Sentience Collection

Tool use was once considered the sole domain of humans. Over the last 40 years, however, it has become apparent that tool use may be widespread across the animal kingdom. Pioneering studies in primates have shaped the way we think about tool use in animals, but have also lead to a bias both in terms of our expectations about which animals should be capable of using tools and the working definition of tool use. Here I briefly examine tool use in terrestrial animals and consider the constraints of the current working definition of tool use in fishes. Fishes lack grasping …

The breeding chute proved superior over traditional chutes in a variety of ways. Improvement occurred in the areas of consideration as follows, user operation was simplified, animal stress was decreased, and maximum breeding efficiency was obtained.

Isotopic Niche Differentiation Among Mammals From A Rainforest In Peninsular Malaysia, Kae Kawanishi, Song Horng Neo Liang, Chris T. Darimont, Thomas E. Reimchen, Melvin E. Sunquist

Biochemistry Collection

We performed stable isotope analysis on eight mammalian species: pig-tailed macaque (Macaca nemestrina), long-tailed macaque (M. fascicularis), dusky leaf monkey (Trachypithecus obscurus), brush-tailed porcupine (Atherurus macrourus), wild boar (Sus scrofa), lesser mouse-deer (Tragulus javanicus), greater mouse-deer (T. napu), and barking deer (Muntiacus muntjac), to test the hypothesis that the differences in diet and habitat types among species, guilds and foraging strategies are reflected in the δ¹⁵N and δ¹³C signatures of their tissues. Whereas the isotopic ratios differed among taxa, the four major isotopic groups observed were: mouse-deer species, primate species, brush-tailed porcupine, and wild boar. The …

Notes On The Diet Of The Malay Civet (Viverra Tangalunga) And Other Civets In Logged And Unlogged Lowland Dipterocarp Rain Forests In Sabah, Borneo, Christina P. Colon, John B. Sugau

Publications and Research

Civet diets were examined in a logged and unlogged Bornean rain forest. Malay civets (Viverra tangalunga) consumed invertebrates, fruit, rodents, insectivores, birds, snakes and lizards, and appear to show preference for centipedes and scorpions. Other civet species consumed fruit, such as figs, Connarus sp. and Annona sp., particularly in the unlogged forest, but also consumed invertebrates and vertebrates. Reduced fruit consumption observed in the logged forest may be due to lower availability and may be offset by increased consumption of invertebrates. The increased overlap in diet between Malay civets and other civets in disturbed areas may lead to …

An Hsi Report: Industrial Farm Animal Production And Livestock Associated Mrsa (Methicillin Resistant Staphylococcus Aureus), Humane Society International

HSI REPORTS

Staphylococcus aureus is a leading cause of bacterial infection and is increasingly found to be resistant to antibiotic therapy. A newly described type of Methicillin Resistant Staphylococcus aureus carried by farm animals, Livestock Associated MRSA (LA-MRSA), is now causing infections in humans with and without direct livestock contact. A reduction in the non-therapeutic use of antibiotics in feed would likely reduce the capacity of industrial animal agriculture to continue to create, disseminate, and perpetuate a large reservoir of LA-MRSA on a global scale, but more fundamental changes in the way animals are raised for food may be necessary forestall a …

Confronting Language, Representation, And Belief: A Limited Defense Of Mental Continuity, Kristin Andrews, Ljiljana Radenovic

Sentience Collection

According to the mental continuity claim (MCC), human mental faculties are physical and beneficial to human survival, so they must have evolved gradually from ancestral forms and we should expect to see their precursors across species. Materialism of mind coupled with Darwin’s evolutionary theory leads directly to such claims and even today arguments for animal mental properties are often presented with the MCC as a premise. However, the MCC has been often challenged among contemporary scholars. It is usually argued that only humans use language and that language as such has no precursors in the animal kingdom. Moreover, language is …

Clinical Anesthesia And Analgesia In Fish, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Fish have become a popular experimental model and companion animal, and are also farmed and caught for food. Thus, surgical and invasive procedures in this animal group are common, and this review will focus on the anesthesia and analgesia of fish. A variety of anesthetic agents are commonly applied to fish via immersion. Correct dosing can result in effective anesthesia for acute procedures as well as loss of consciousness for surgical interventions. Dose and anesthetic agent vary between species of fish and are further confounded by a variety of physiological parameters (e.g., body weight, physiological stress) as well as environmental …

Characterisation Of Chemosensory Trigeminal Receptors In The Rainbow Trout, Oncorhynchus Mykiss: Responses To Chemical Irritants And Carbon Dioxide, Jessica J. Mettam, Catherine R. Mccrohan, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Trigeminally innervated, mechanically sensitive chemoreceptors (M) were previously identified in rainbow trout, Oncorhynchus mykiss, but it is not known whether these receptors are responsive only to noxious, chemical irritants or have a general chemosensory function. This study aimed to characterise the stimulus–response properties of these receptors in comparison with polymodal nociceptors (P). Both P and M gave similar response profiles to acetic acid concentrations. The electrophysiological properties were similar between the two different afferent types. To determine whether the receptors have a nociceptive function, a range of chemical stimulants was applied to these receptors, including non-noxious stimuli such as ammonium …

Prevalence Of Antibodies To Canine Parvovirus And Distemper Virus In Wolves In The Canadian Rocky Mountains, Brynn Nelson, Mark Hebblewhite, Vanessa Ezenwa, Todd Shury, Evelyn H. Merrill, Paul C. Paquet, Fiona Schmiegelow, Dale Selp, Geoff Skinner, Nathan Webb

Epidemiology Collection

Wild carnivores are often exposed to diseases via contact with peridomestic host species that travel through the wildland-urban interfaces. To determine the antibody prevalences and relationships to human activity for two common canid pathogens, we sampled 99 wolves (Canis lupus) from 2000 to 2008 for antibodies to canine parvovirus (CPV) and canine distemper virus (CDV) in Banff and Jasper National Parks and surrounding areas of the Canadian Rockies. This population was the source for wolves reintroduced into the Northern Rockies of the US. Of 99 wolves sampled, 94 had detectable antibody to CPV (95%), 24 were antibody-positive for CDV (24%), …

Animal Learning And Training: Implications For Animal Welfare, Sabrina I.C.A. Brando

Assessment of Animal Welfare Collection

KEY POINTS

• A definition of animal welfare is the state of the individual as it attempts to cope with its environment.
• Welfare concerns all of the mechanisms for coping, involving physiology, behavior, feelings, and pathologic responses.
• When training programs are not in place the animal’s welfare could be impaired.
• Some of the behaviors an animal exhibits can be used to gain insight into how the animal feels about the environment, caretakers, and procedures.
• Many contemporary animal trainers and care specialists focus on building relationships using positive reinforcement.

Mammary Cell Activity And Turnover In Dairy Cows Treated With The Prolactin-Release Inhibitor Quinagolide And Milked Once Daily, M. Boutinaud, V. Lollivier, L. Finot, R. M. Bruckmaier, P. Lacasse

Physiology Collection

To assess the regulation of mammary cell activity, survival, and proliferation by prolactin (PRL), 5 Holstein cows in early lactation received daily i.m. injections of 1 mg of quinagolide, a suppressor of PRL release, for 9 wk, whereas 4 control cows received the vehicle (water) only. During the last week of treatment, one udder half was milked once a day (1×) and the other twice a day (2×). Mammary biopsies were harvested 1 wk before and 4 and 8 wk after the start of quinagolide treatment. The quinagolide injections reduced milk yield and resulted in lower levels of κ-casein and …

Department of Animal Science: Faculty Publications

The use of terminal sires (TS) for crossbreeding is integral to the UK sheep industry where approximately 71% of market lambs are sired by TS rams. Early growth of these crossbred lambs affects profitability. The objectives of this study were i) to evaluate the effectiveness of index selection among TS on BW and ADG of their crossbred offspring; and ii) to compare the efficacy of that selection within TS breeds. The most widely used TS breeds in the United Kingdom are Charollais, Suffolk, and Texel. These participated in sire referencing schemes in which they were evaluated on a lean growth …

Magnitude And Structure Of Lymantria Dispar Asiatica Infestations Of Common Forest Steppe Tree Species In Northern Mongolia, Nina Tiralla, Kai Füldner, Stefan Schütz

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Lymantria dispar L. is one of the most serious forest pests worldwide by infesting large forest areas involving massive tree dieback. Unlike outbreaks of Lymantria dispar L. in Germany that cause massive defoliation, observations of outbreaks of Lymantria dispar asiatica made in the research area Khonin Nuga, West Khentii, Mongolia during the past six years showed only punctual defoliation, and dieback was extremely scarce. However, information on the performance of Lymantria dispar asiatica and the corresponding reaction of host tree species in Khonin Nuga is rare. Therefore, this study concentrates on the examination of primarily affected tree species and the …
