Interest is increasing regarding use of Cannabidiol (CBD) in companion animals due to anecdotal evidence of beneficial behavioral and health effects. The purpose of this investigation was to evaluate the influence of CBD on behavioral responses to fear-inducing stimuli in dogs. Sixteen dogs (18.1 ± 0.2 kg) were utilized in a replicated 4 × 4 Latin square design experiment with treatments arranged in a 2 × 2 factorial, consisting of control, 25 mg CBD, trazodone (100 mg for 10–20 kg BW, 200 mg for 20.1–40 kg BW), and the combination of CBD and trazodone. A fireworks model of noise-induced fear …
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson
All HCAS Student Capstones, Theses, and Dissertations
Wildlife tourism is increasing in popularity around the world, creating the need to understand alterations in animal behavior and spatial distributions that may occur due to associated anthropogenic disturbances. Nurse sharks (Ginglymostoma cirratum, Bonnaterre 1788) are commonly used for wildlife tourism within the Caye Caulker Marine Reserve in Belize. Shark and Ray Village (SRV) is a site within the reserve where nurse sharks are consistently fed by tour/snorkel boats to create an interactive experience with tourists, termed provisioning tourism. Prior to this experiment, no studies had been conducted in SRV to evaluate the impact of provisioning tourism (tourism …

The study focuses on the second-youngest and youngest males in the troupe and how they interact with each other. S. oedipus possess certain social and communication behaviors. The main behaviors observed in this study are vocalizations and movements indicating aggression between the two …
Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris
Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris
University of New Orleans Theses and Dissertations
Although the hypoxia-inducible transcription factor (HIF) orchestrates molecular responses to low oxygen, the amount of HIF-1α protein expressed during hypoxia varies among species, individuals, and tissues. This study measured HIF-1α protein levels along with several physiological and behavioral variables in the estuarine fish Fundulus grandis under normoxia (> 7 mg l-1 dissolved oxygen) and hypoxia (1 mg l-1 dissolved oxygen). Fish under hypoxic conditions had higher tissue levels of HIF-1α, hematocrit, blood glucose, blood lactate, frequency of aquatic surface respiration (ASR), and lower activity than normoxic controls. Under hypoxia, HIF-1α abundance in gill was positively correlated with body …
Multivariate Analysis Of Open Field Exploration Identifies Latent Spatial And Social Behavioral Axes In Domestic Dogs, Budhaditya Chowdhury, Moira Van Staaden, Robert Huber
Multivariate Analysis Of Open Field Exploration Identifies Latent Spatial And Social Behavioral Axes In Domestic Dogs, Budhaditya Chowdhury, Moira Van Staaden, Robert Huber
Advanced Science Research Center
Recent methodological advances in studying large scale animal movements have let researchers gather rich datasets from behaving animals. Often collected in small sample sizes due to logistical constraints, these datasets are however, ideal for multivariate explorations into behavioral complexity. In behavioral studies of domestic dogs, although automated data loggers have recently seen increasing use, a comprehensive framework to identify complex behavioral axes is lacking. Dog behavioral studies frequently rely on subjective ratings, despite demonstrable evidence that these are insufficient for identifying behavioral variables. Taking advantage of dogs’ innate running abilities and readily available GPS data loggers, we extracted latitude-longitude coordinates …
Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger
Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger
Murray State Theses and Dissertations
A multitude of claims exist regarding therapeutic benefits of cannabidiol (CBD) in human and animal medicine. Though supportive evidence of CBD as a nutraceutical option exists, lack of regulation means that product safety, consistency, and efficacy cannot be guaranteed. Trials for specific conditions and species are needed. The objective of this study was to evaluate CBD safety and use effects on reactivity and movement in the horse. Project 1 examined the bioavailability of a single 50 mg dose of an oil and pelleted CBD product. One of 2 Quarter Horse geldings received the oil product. The second received the pelleted …

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human– vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts …

BACKGROUND: Anticoagulant rodenticides are used worldwide to control pest rodent species. However, the risks posed to nontarget reptiles have not been well characterized. In this study, 46 giant ameivas (Ameiva ameiva), 39 boa constrictors (Boa constrictor), 33 wood turtles (Rhinoclemmys pulcherrima), and 47 green iguanas (Iguana iguana) were orally dosed with one of two levels of either diphacinone or brodifacoum anticoagulant in propylene glycol solutions. Dosages were derived using daily food intake (DFI) equations, converting DFI to an equivalent anticoagulant bait amount and gavaging the solution volume needed to deliver the quantity of anticoagulant in that amount of bait. Animals …
Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall
Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall
All Master's Theses
This study aimed to establish preliminary health and behavioral data, as well as understand group variation for a large population of Macaca fascicularis individuals within an anthropogenically altered monkey forest. A parasitic analysis of 40 mother and infant individuals showed that M. fascicularis carried 13 different parasitic taxa, and that there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three other groups. Mother-infant behavioral differences were seen between …

Effect Of The Prospect Of Transport On Captive Tiger Behavior And Fecal Cortisol In Naïve And Experienced Tigers, Callan Lichtenwalter
Graduate Theses and Dissertations
With close to 5,000 captive tigers in the United States, it is vital to ensure that these tigers are receiving adequate welfare whether they are in an accredited facility, or privately owned. The goal of this study was to assess whether captive tigers at a rescue facility with experience being transported outside of the facility would respond differently to the presentation of their transport vehicle than their naïve counterparts who had only been transported within the facility. The behavior of 5 naïve and 7 experienced tigers (n = 12) located at Turpentine Creek Wildlife Refuge in Eureka Springs, Arkansas was …
Stressed Out: Life-History Strategy And The Costs Of Multiple Stressors In Gryllus Crickets, Sugjit S. Padda
Stressed Out: Life-History Strategy And The Costs Of Multiple Stressors In Gryllus Crickets, Sugjit S. Padda
University of the Pacific Theses and Dissertations
The frequency, duration, and co-occurrence of several environmental stressors are increasing globally. Multiple stressors may have compounding or interactive effects on animals, resulting in either additive or non-additive costs, but animals may mitigate these costs through various strategies of resource conservation or shifts in resource allocation. Thus, through two related factorial experiments, I measured a range of traits—from those related to life history and behavior to underlying physiology— to investigate the nature of costs (additive, non-additive, or neither additive nor non-additive), cost-mitigating strategies (resource conservation or allocation), and life-history strategy related to multiple stressors. First, I leveraged life-history strategy differences …
