Long-Term Abundance Estimates Of A Northeast Florida Estuarine Dolphin Community: Evaluating The Impacts Of The 2013–2015 Cetacean Morbillivirus Unusual Mortality Event, Allison L. Wilkins
Long-Term Abundance Estimates Of A Northeast Florida Estuarine Dolphin Community: Evaluating The Impacts Of The 2013–2015 Cetacean Morbillivirus Unusual Mortality Event, Allison L. Wilkins
UNF Graduate Theses and Dissertations
Tamanend's bottlenose dolphins (Tursiops erebennus) in the St. Johns River (SJR), Jacksonville, FL, are subjected to substantial anthropogenic stressors (e.g., vessel traffic, dredging, fisheries interactions) and were heavily impacted by the 2013-2015 Mid-Atlantic cetacean morbillivirus unusual mortality event (UME). High prevalence of skin lesions and frequent sightings of emaciated dolphins suggest declining health and viability of the SJR dolphin community. Sighting data from Jul. 2011 to Oct. 2019 provided the rare opportunity to investigate long-term changes in dolphin abundance surrounding the UME. This study produced the first dolphin abundance estimate within the Jacksonville Estuarine System stock since 1997, …
Severe Aggression Among Zoo-Housed Coconut (Trichoglossus Haematodus) And Rainbow (Trichoglossus Moluccanus) Lorikeets: Wellbeing Considerations For Free-Flight Aviaries, Emily Simkins
UNF Graduate Theses and Dissertations
As conservation and education institutions, modern zoos balance the needs of animals with the interests of visitors through several strategies which can increase animal wellbeing and improve visitor experience. Environmental enrichment is frequently employed to increase the suitability of anthropogenic environments for zoo-housed animals, such as through walkthrough habitats and free-flight aviaries. While habitats such as these are important for visitor experience and can be enriching to animals, there are also wellbeing considerations for these spaces. Walkthrough habitats can be a potential source of fear and stress for animals, as shown by increased frequencies of vigilance, undesirable behavior, and aggression. …
Exploring The Welfare Of A Captive Population Of Cownose Rays (Rhinoptera Bonasus) Through Social And Resource Interactions, Kendal N. Rogers
Exploring The Welfare Of A Captive Population Of Cownose Rays (Rhinoptera Bonasus) Through Social And Resource Interactions, Kendal N. Rogers
UNF Graduate Theses and Dissertations
Zoos and aquariums utilize research-based management to ensure animals remain in a positive welfare standing. While vital, this research is taxa-biased towards mammals, with few studies observing other species that are frequently observed in captivity, such as elasmobranchs, or sharks and rays. Often maintained in exhibits that allow direct guest interaction, or touch pools, elasmobranchs have been shown to respond to these exposures through behavior changes in activity and social interactions. While this may indicate a potential for compromised welfare, the literature is conflicting and sparse, leaving uncertainty in the overall welfare condition of animals maintained in this popular exhibit …
Effects Of Environmental And Anthropogenic Factors On Loggerhead Sea Turtle (Caretta Caretta) False Crawl Rates On Jekyll Island, Ga, Brittany Byrd
Effects Of Environmental And Anthropogenic Factors On Loggerhead Sea Turtle (Caretta Caretta) False Crawl Rates On Jekyll Island, Ga, Brittany Byrd
UNF Graduate Theses and Dissertations
Loggerhead sea turtles (Caretta caretta) are currently listed as “vulnerable” on the IUCN Red List and are experiencing population declines across many parts of their range. These declines are caused by environmental and anthropogenic stressors which impact sea turtle ecology and behavior, including nesting behavior. One nesting behavior sea turtles exhibit is known as “false crawling,” which is when a female sea turtle ascends the beach in an attempt to nest and either abandons the attempt altogether or while in the middle of digging an egg chamber. False crawling, a largely understudied sea turtle behavior, can not only …
Residency And Sociality Analysis Of Skin Lesions In Bottlenose Dolphins (Tursiops Truncatus) Of The St. Johns River, Fl, Brittney Divittore-Goodrum
Residency And Sociality Analysis Of Skin Lesions In Bottlenose Dolphins (Tursiops Truncatus) Of The St. Johns River, Fl, Brittney Divittore-Goodrum
UNF Graduate Theses and Dissertations
Photo analysis of skin lesions is a non-invasive method to measure the health of cetacean populations. The St. Johns River (SJR) in NE Florida is an estuarine system inhabited by bottlenose dolphins that is characterized by high levels of anthropogenic activity, which can impact dolphin health. Social transmission of disease may influence lesion formation in dolphins; thus this study aimed to determine if skin lesion prevalence and body coverage differed based on 1) the amount of time spent in the SJR annually and 2) sociality measures. The dataset was restricted to three 12-month periods, based on the occurrence of an …
Implementing Welfare Science: Case Studies In Evidence-Based Zoo Management, Marisa Suzanne Spain
Implementing Welfare Science: Case Studies In Evidence-Based Zoo Management, Marisa Suzanne Spain
UNF Graduate Theses and Dissertations
Animal welfare science is a field that focuses on how we can improve the lives and well-being of animals in human care. Modern welfare science has moved away from simply preventing suffering and on to promoting positive welfare states, a concept that has been coined animal “wellness”. A process called evidence-based zoo management has been implemented in many zoos as a way to promote and ensure wellness. This is the idea that husbandry and housing standards should be evaluated and tested for their efficacy using data rather than relying on traditional best practices. In this manuscript we discuss an informal …
Behavioral Assessment Of Social Structure And Guest Provisioning Program Participation Of Zoo-Housed Giraffes (Giraffa Camelopardalis) Under Varying Spatial Availability., Fatima Ramis
UNF Graduate Theses and Dissertations
Close encounters with animals are considered integral for visitors and are trademark components of traditional educational engagement in zoological parks. As capacity for up-close encounters continue to increase with a simultaneous development in the field of animal welfare science, behavioral assessments on the role of common close encounters is timely. Giraffes (Giraffa camelopardalis) visitor feeding programs are established in approximately 57% of institutions accredited by Association of Zoos and Aquariums. Due to successful breeding and capacity building for zoological giraffe populations, this percentage will likely continue to increase. There is a great deal of variation in the environmental …
Assessment Of Spatial Overlap And Social Mixing As A Pathway For Disease Transmission In A Northeast Florida Estuarine Dolphin Population, Emily A. Szott
Assessment Of Spatial Overlap And Social Mixing As A Pathway For Disease Transmission In A Northeast Florida Estuarine Dolphin Population, Emily A. Szott
UNF Graduate Theses and Dissertations
Bottlenose dolphins (Tursiops truncatus) in estuarine systems are often subjected to natural and anthropogenic risks, which may impact their health and behaviors. Effective management for this species should incorporate continual, updated information on behavioral patterns of a stock’s individuals. Currently, the Jacksonville Estuarine System stock assessment report, which includes dolphins in the St. Johns River (SJR) in northeast Florida, is based on data from the 1990s. Since then, dolphins’ use of the SJR has shifted, and the population has been impacted by two unusual mortality events (UME). This study analyzed site fidelity, space use and overlap, and social …
The Effects Of The Red Tide Producing Dinoflagellate, Karenia Brevis, And Associated Brevetoxins On Viability And Sublethal Stress Responses In Scleractinian Coral: A Potential Regional Stressor To Coral Reefs, David A. Reynolds
UNF Graduate Theses and Dissertations
Coral cover is in decline on a global scale, with increased mortality events being attributed to a number of global and regional stressors. While the impacts of global stressors (e.g. sea surface temperature rise, ocean acidification) are well documented, there is growing interest in identifying and understanding the impacts of regional stressors. The reason for this change in focus is that regional stressors can often work in combination, sometimes synergistically, with global stressors and that stressors on a regional scale tend to be more easily mitigated by management practices. One regional stressor that impacts a myriad of marine organisms in …
The Soundscape Of The St. Johns River And Its Potential Impacts On The Habitat Use Patterns Of Bottlenose Dolphins, Carissa Deeann King
The Soundscape Of The St. Johns River And Its Potential Impacts On The Habitat Use Patterns Of Bottlenose Dolphins, Carissa Deeann King
UNF Graduate Theses and Dissertations
The development of effective management plans for animal populations relies on an understanding of how the population is utilizing the habitat as well as the identification of any critical habitat areas. The St. Johns River (SJR), an urban estuary with a high level of anthropogenic disturbance, is home to a resident population of bottlenose dolphins (Tursiops truncatus). In chapter one, SJR dolphin habitat use patterns, the factors that influenced these patterns, and the critical habitat areas were identified. Significant associations were found in most pair-wise comparisons between season, behavioral state, group size, water depth, and location, indicating that …
Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant
Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant
UNF Graduate Theses and Dissertations
Based on recognized life history traits and ecology, zoos strive to house their gorillas (Gorilla gorilla gorilla) in mixed-sex groups with one mature male or silverback, multiple females, and their offspring. However, successful captive breeding programs and a nearly 50:50 birth sex ratio has created the need to house surplus males in solitary conditions or all-male groups. It is commonly believed that male western gorillas will not tolerate one another in the presence of females; however, multi-male, mixed-sex groups have been observed in the wild. For this reason, some zoos have begun experimenting with this scenario. At the …
Structure And Function Of Male Bottlenose Dolphin Alliances In Northeast Florida, Kristin A. Karle
Structure And Function Of Male Bottlenose Dolphin Alliances In Northeast Florida, Kristin A. Karle
UNF Graduate Theses and Dissertations
Bottlenose dolphins exhibit fission-fusion social systems in which group size and composition change fluidly throughout the day. Societies are typically sexually segregated, and the quality and patterning of individual relationships in this social species shape the social structure of a population. Female dolphins usually have a large network of associates with whom they form recurring moderate bonds, while male associations are highly variable due to their mating strategies. Males employ one of two strategies; males may be solitary, and encounter and herd females individually, while others may form strong bonds with one to two other males and cooperatively herd individual …
