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.

What Is It Like To Be A Cognitive Ethologist?, Anne Wordsworth She/Her

Animal Sentience

Donald Griffin not only made the study of animal minds acceptable for scientific investigation but the work of the cognitive ethologists that he inspired made animals and their lives fascinating and accessible to the greater public. The scrupulously detailed examination of his life and work by Ristau ensures that this history will always be there to respect his work and his legacy

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.

The Utilization Of String Pulling To Determine Female Rats' Dual Cognitive Motor Task Performance Following Space Flight Stressor Exposure, Doc-Haden Rodgers, Nicole M. Atttallah, Teresa L. Garcia, Nuhamine A. Moges, N. A. Moges, K. D. Omengan, J. F. Cortez, K. S. Dhede, A. A. Blackwell

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 …

The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell

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

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 …

Effects Of Low Dose Exposure To Radiation And Sleep Fragmentation On Discrimination In String-Pulling Behavior With Female Rats, Jonathan F. Cortez, Diana Lloyd, T. L. Garcia, A. Adhikari, N. M. Attallah, N. Moges, D. H. Rodgers, K. S. Dhede, K. D. Omengan, A. A. Blackwell

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

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

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.

Blackbird, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The introduced common blackbird (Turdus merula) is a pest in eastern Australia. It damages commercial fruit crops and may compete with native birds. The species is prohibited in Western Australia and individuals found here are destroyed.

The Western Australian Organism List (WAOL) contains information on the area(s) in which this pest is declared and the control and keeping categories to which it has been assigned in Western Australia (WA). For more information, see our website at dpird.wa.gov.au.

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 …

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano

Animal Sentience

Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …

Root Lesion And Burrowing Nematodes And Their Management, Department Of Primary Industries And Regional Development, Western Australia

Variability In Associations Among Seabirds And Marine Mammals: Causes And Consequences, Samantha A. Monier

Dissertations, Theses, and Capstone Projects

Marine predators today face multifaceted stressors from changing climate to changing prey availability, and these changes are occurring at unprecedented speeds. Any alteration to a species’ environment has the potential to disrupt social networks and thus, how animals obtain and transfer information. Interspecific social interactions in the form of local enhancement and facilitation are a critical, but not yet well-understood, component of seabird foraging; of immediate concern is that anthropogenic changes may be altering the quantity and quality of positive species interactions, with consequences for the species involved.

While we know these interactions are not immutable, less is known about …

Exploring The Roles Of Physiology And Phylogeny In Novel Signal Evolution, Mia E. Phillips

Dartmouth College Ph.D Dissertations

In animal communication, signal phenotypes are shaped by a combination of selective

forces pushing for improved transmission, efficiency, and detection, and limited by

developmental constraints in signal production and reception abilities (Morton 1975; Guilford &

Dawkins 1991; Endler 1992; Davranoglou et al. 2023). These opposing forces have resulted in

communication strategies that are broadly diverse yet similar among closely related species. We

expect to see gradual changes in signal phenotypes across different clades (Harvey & Pagel

1991). Sometimes, though, the communication strategies of closely related taxa are drastically

different (Ligon et al. 2018), indicating that selection must have overcome the …

The Effects Of People, Time Of Day, And Season On Affiliative And Stereotypic Behaviors In Captive Rhinoptera Bonasus And Other Rays Across Two Human-Interactive Enclosures, Wren C. A. Newman

Theses and Dissertations

Cownose rays (Rhinoptera bonasus) are among the most common species found in aquaria, yet the impact of touch enclosures on their welfare remains largely unknown. While research on animal-visitor interactions has produced mixed results for other species, the lack of studies focusing on fish welfare poses a risk of overlooking potential welfare concerns. Therefore, we aimed to establish a baseline for cownose rays regarding stereotypic behaviors, sociality, and activity in captivity, and to examine the influence of human interaction on these behaviors. We collected over 700 hours of footage from two enclosures at Adventure Aquarium in Camden, NJ …

The Effect Of Moon Phase On Predator And Prey Activity Levels On Turnbull National Wildlife Refuge, Jeff Schell, Charlotte Milling

2024 Symposium

Variation in nighttime illumination linked to moon phase has been demonstrated to affect the activity patterns of both prey and predator species. However, evidence of lunarphobia in ungulates is mixed. Turnbull National Wildlife Refuge (TNWR) in Spokane County spans 23,000 acres; features a diverse landscape of channeled scablands, wetlands, and Ponderosa pine (Pinus ponderosa); and is situated within 20 km of the second largest city in Washington. Our objective was to assess the influence of nighttime illumination on activity levels of common mammals on TNWR by quantifying the relationship between moon phase and visitation rate at trail cameras …

The Behavioral Specialization Of African Ant-Following Birds On Dorylus Driver Ants, Patricia F. Rodrigues

LSU Doctoral Dissertations

Ant-following birds, that forage on arthropods flushed by swarm raiding army ants, are an iconic phenomenon in tropical forests around the globe. Despite capturing the attention of naturalists for over a century, research on ant-following birds has largely focused on Neotropical species. Decades of research on Neotropical ant-following birds has revealed fascinating aspects of their specialization, including complex cognitive and behavioral adaptations that allow birds to locate and track nomadic army ants. Despite this breadth of research on Neotropical species, virtually nothing is known of the behavioral ecology of African ant-following birds, and it remains unknown whether they exhibit adaptations …

Records Of The Red-Bellied Snake (Storeria Occipitomaculata) In Central And Northeastern Nebraska, Taylor Lowe, Sarah M. Bailey, Dan D. Fogell, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Red-bellied Snakes (Storeria occipitomaculata) are a distinctive, small species that live in moist woodlands throughout much of eastern North America. In the Great Plains, isolated populations exist in South Dakota, Wyoming, and Nebraska. In Nebraska, the only known extant population occurs in wooded riparian habitats along the Big Bend Reach of the Platte River in southcentral parts of the state. Herein, we report on new county records of Red-bellied Snakes in Nebraska, with two observations from Merrick County along the Platte River adjacent to known populations and two observations of a new population in the extreme northeastern part …

The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux

LSU Doctoral Dissertations

Sexually transmitted infections (STIs) remain an economic and social burden, non-discriminately affecting sexually active individuals worldwide. The unique transmission of STIs is dependent upon host and pathogen life histories, as well as the underlying network structure of the host population. Within a population there is a group of individuals, the core group, that maintains STI presence and helps sustain ongoing transmission both within the core group and in the surrounding population. While the presence of these core groups is well documented, the criteria for inclusion into a sexual core group is not. In this dissertation, I explore common factors that …

Microplastic Accumulation In The Marsh Periwinkle (Littoraria Irrorata), Sarah Keaton, Hannah Lukhard, Eli Windy, Manar Hasan

DePaul Discoveries

Contamination of oceans by microplastics (mm) currently poses a major threat to aquatic and terrestrial ecosystems worldwide. Recent attention towards this issue has raised questions about the extent to which microplastics have accumulated in the environment, and has led to an increase in studies on the effects of microplastics in various organisms. However, levels of contamination in protected natural areas are still largely unexplored, yet can offer an important empirical perspective on the issue. In addition, little is known about the potential effects of microplastics on behavior in the field. This research was conducted within the protected ACE Basin National …

Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff

Animal Sentience

Individual differences in personality types within the same species have been studied much less than differences between species and populations. Personality differences are related to risk-taking and exploration, which in turn correlate with individuals' daily responses, decisions, and fitness. Bold and shy personality types can have different advantages and disadvantages under different social or environmental pressures. Analyzing personality differences has helped clarify how elk habituate to a well-populated area and how management strategies can be adapted to them. For wolves newly repatriated to Colorado, individual personality factors are likely to prove important for adapting to their new homes as well …

The Ecological Applications Of Δ17O: Validating A Novel Technique For Assessing Animal Metabolism And Water Intake, Zachary Taylor Steele

Biological Sciences Theses & Dissertations

Animals obtain water via different processes such as drinking, consuming food, and through metabolic processes like at the end of the electron transport chain when atmospheric oxygen is combined with hydrogen to form ‘cytochrome oxidase water’. Assessing animal water flux and metabolism has mainly been conducted via stable isotope analysis (SIA) of biological samples using hydrogen (²H) and oxygen isotopes (¹⁶O, ¹⁷O, and ¹⁸O; Δ¹⁷O), typically using enriched isotope tracers. However, natural abundance isotope modeling offers an approach for conducting SIA of biological samples that differs because it relies on the unique, …
