Severe Aggression Among Zoo-Housed Coconut (Trichoglossus Haematodus) And Rainbow (Trichoglossus Moluccanus) Lorikeets: Wellbeing Considerations For Free-Flight Aviaries, Emily Simkins 2025 University of North Florida

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. …


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 2025 University of North Florida

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, …


Griffin's Slow Burn Revolution In Philosophy And Comparative Cognition, Kristin Andrews 2024 York University; Canadian Institute for Advanced Research

Griffin's Slow Burn Revolution In Philosophy And Comparative Cognition, Kristin Andrews

Animal Sentience

Ristau presents Griffin as launching a scientific revolution supported by philosophical insights. This commentary focuses on two points: Griffin as a scientific revolutionary, although the cognitive ethology revolution is not yet complete; and on the immense influence Griffin had, and continues to have, on philosophy.

Can Animal Consciousness Be Resolved Scientifically?, Yoram Gutfreund

Animal Sentience

Carolyn Ristau's biography of Donald Griffin is a comprehensive work that sheds light on a seminal chapter in the history of ethology—the ambitious attempt to establish a research field dedicated to animal consciousness. Although Donald Griffin's endeavor ultimately fell short of its revolutionary goals, it catalyzed significant progress in understanding evolution and mechanisms of animal cognition.

Beyond Human Perception: The Remarkable Science Of Donald R. Griffin, Gareth Jones

Animal Sentience

Carolyn Ristau shows how Donald Griffin’s revolutionary science sometimes progressed from ridicule, to opposition, to being self-evident. Griffin’s work involved phenomena beyond human perception, making it sometimes difficult for others to fathom. His work on ultrasonic echolocation, navigation and animal cognition has shifted established paradigms. His ‘zoomorphic’ approach provides a realistic framework for understanding how other animals perceive the world.

Donald Griffin: A Visionary In Science And Consciousness, Brock Fenton

Animal Sentience

I share some reflections on a sabbatical with Donald Griffin a half-century ago, with fieldwork on bats and echolocating swiftlets in Australia and our discussions of animal behavior and consciousness. Griffin's influence has been vast, from recent advances in bat research, including learning, navigation, and longevity, to his enduring legacy as a pioneer in animal cognition.

Undergraduate Research Symposium Posters

During deep space exploration, astronauts depend on mission-essential performance in Dual Cognitive Motor Tasks (DCMT), such as receiving information from ground control to assemble and configure wires during a spacewalk. DCMT relies upon processing cognitive and motor information simultaneously. Previous research on rodent models has shown various impairments in cognition and motor function in separate tasks after exposure to deep space radiation and sleep fragmentation (SF). However, an assessment of DCMT performance in rodents has not been established. Rats and humans use similar hand-over-hand movements to pull a string, and task demands may be varied to assess cognition and motor …

Undergraduate Research Symposium Posters

Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …


Effect Of Macronutrients On A Rat Model Of Clostridioides Difficile Infection, Stephanie Yang, Maria Niamba, Rose Jiang, Ashton Wippel, Efren Heredia, Liliko Watanabe, Katrina Valadez, Erica Bacab, Ernesto Abel-Santos 2024 University of Nevada, Las Vegas

Effect Of Macronutrients On A Rat Model Of Clostridioides Difficile Infection, Stephanie Yang, Maria Niamba, Rose Jiang, Ashton Wippel, Efren Heredia, Liliko Watanabe, Katrina Valadez, Erica Bacab, Ernesto Abel-Santos

Undergraduate Research Symposium Posters

Clostridioides difficile (C. diff) is an anaerobic, spore forming, gram-positive bacteria. C. diff is the causative agent of C. difficile infections (CDIs) and is recognized as the leading cause of nosocomial infective diarrhea worldwide. CDI is associated with the use of antibiotics that alter the gut microbiome and C. diff resides in the large intestine where onset of the disease then occurs. Having observed the impacts of CDI on mice models, the Abel-Santos lab now shifts to observing this infectious disease in rat models. Establishing the infectious dosage at 109 spores, this study aims to identify the correlation between diet …

Undergraduate Research Symposium Posters

Astronauts will face harmful stressors, such as galactic cosmic radiation (GCR) and sleep fragmentation (SF), on a three-year space flight mission to Mars and back. Astronauts perform skilled reach-to-grasp behaviors on these missions, including interacting with controls to navigate the spacecraft. Recent work has shown that GCR and SF disrupt skilled reach-to-grasp behavior in rodent models; however, the underlying nature of these deficits is unknown. To determine if tactile sensation and proprioceptive feedback contribute to these impairments, this study evaluated the effects of radiation and SF exposure on memory and sensorimotor discrimination in a rodent model. Twenty-one outbred Wistar, retired …

Rabbit Control In Urban And Semi-Urban Areas, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet provides information on control options for rabbits in urban and semi-urban areas in Western Australia (WA).

Rabbits cause considerable losses to agricultural and horticultural industries. They can cause serious environmental problems, such as soil erosion and degradation of native vegetation. Rabbits also compete with native fauna for food and habitat.

Rabbits may be a problem or a nuisance in urban environments where they can damage lawns and gardens, buildings, garages, and sheds. Rabbits can also damage golf courses, sports grounds, and parkland reserves.

The options for control of rabbits in urban areas are more limited than in rural …


Effects Of Retinal Gonadotropin-Releasing Hormone On Reproductive Behavior And Retinal Activity In The Cichlid Fish, Astatotilapia Burtoni, Chase Anselmo 2024 Louisiana State University and Agricultural and Mechanical College

Effects Of Retinal Gonadotropin-Releasing Hormone On Reproductive Behavior And Retinal Activity In The Cichlid Fish, Astatotilapia Burtoni, Chase Anselmo

LSU Master's Theses

Many animals use visual signals to evade predators, forage for food, and communicate with conspecifics. Some animals that shift into and out of breeding stages, such as fish, can modulate their visual sensitivity to better adapt to changing internal and external conditions. Previous work in our lab demonstrated that females of the cichlid fish Astatotilapia burtoni have improved visual sensitivity when they enter reproductive readiness. However, little is known about how fish and vertebrates more broadly modulate visual sensitivity across their reproductive cycle. We hypothesized that the hormone and neuromodulator gonadotropin-releasing hormone (GnRH) could modulate visual sensitivity because GnRH is …

Observations Of Co-Nest Building And Spawning In Native And Non-Native Chub Species (Nocomis Spp.) In The Swannanoa River, North Carolina, Patrick Ciccotto

Southeastern Fishes Council Proceedings

Co-nest building and spawning among individuals of the native population of River Chub (Nocomis micropogon) and among those of an introduced population of Bluehead Chub (N. leptocephalus) observed in the Swannanoa River (French Broad River basin) during Spring 2024 represents the first time such behaviors have been documented between two species of Nocomis. Observations of these behaviors are described and discussed in the context of potential hybridization and the impact of introduced Bluehead Chubs in the French Broad River basin.


Feral Donkey, Department of Primary Industries and Regional Development, Western Australia 2024 Department of Primary Industries and Regional Development, Western Australia

Feral Donkey, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Donkeys (Equus asinus) were first imported in substantial numbers to Australia in 1866 by Sir Thomas Elder. They were used as pack and draught animals in outlying areas of Western Australia (WA) until the 1930s. They were eventually replaced by the motor vehicle, and unwanted donkeys were released to the wild, where they became feral. The first record of feral donkeys is from the Kimberley in the early 1930s, but it is possible they became feral much earlier.

Feral Goat, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The goat (Capra hircus) was one of the first animals to be domesticated, 8 to 10 thousand years ago. Archaeological work indicates the earliest attempts at domestication were in dry hills surrounding the Mediterranean basin. The ability of goats to utilise the coarse browse of mountainous areas made them suitable for domestication, in preference to sheep. With large-scale domestication of goats throughout the world, goats escaped and established feral goat herds on most continents. Overgrazing by goats has caused severe environmental damage, worldwide.

Goats arrived in Australia with the first fleet. They were introduced to many areas by early settlers …
