Laterality Enhances Cognition In Australian Parrots, Maria Magat, Culum Brown
Laterality Enhances Cognition In Australian Parrots, Maria Magat, Culum Brown
Sentience Collection
Cerebral lateralization refers to the division of information processing in either hemisphere of the brain and is a ubiquitous trait among vertebrates and invertebrates. Given its widespread occurrence, it is likely that cerebral lateralization confers a fitness advantage. It has been hypothesized that this advantage takes the form of enhanced cognitive function, potentially via a dual processing mechanism whereby each hemisphere can be used to process specific types of information without contralateral interference. Here, we examined the influence of lateralization on problem solving by Australian parrots. The first task, a pebble-seed discrimination test, was designed for small parrot species that …

Conservation Genetics And Systematics Of Several Turtles Species In The Southeastern United States, Joshua Robert Ennen
Conservation Genetics And Systematics Of Several Turtles Species In The Southeastern United States, Joshua Robert Ennen
Dissertations
Chelonians (i.e., turtles) are an imperiled group of reptiles with about 66% of the recognized species listed as threatened by the IUCN. Most chelonian species have a unique set of life history traits (i.e., longevity, delayed sexual maturity, and low juvenile survivorship), which makes their populations exceedingly sensitive to increases in adult and juvenile moralities. With numerous anthropogenic effects (e.g., habitat alteration, exploitation, and over harvesting) negatively influencing mortality rates, chelonians have experienced global precipitous declines and extinctions.
This dissertation focuses on species within two chelonian genera, Gopherus and Graptemys. Although these two genera are vastly different ecologically, they are …

Effects Of Coyote Removal On Pronghorn And Mule Deer Populations In Wyoming, Dylan Earl Brown
Effects Of Coyote Removal On Pronghorn And Mule Deer Populations In Wyoming, Dylan Earl Brown
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
I studied the relationship between coyote (Canis latrans) removal and pronghorn (Antilocapra americana) and mule deer (Odocoileus hemionus) density and fawn:doe ratios in southwest Wyoming and northeast Utah in 2007 and 2008. Coyote removal variables studied included the number of coyotes removed, ground hours worked, total hours worked, coyotes removed/aerial gunning hour, coyotes removed/ground work hour, and coyotes removed/total effort hour. None of the variables explained changes observed in fawn:doe ratios of pronghorn or mule deer. The number of coyotes removed, ground hours worked, total hours worked, and coyotes removed/aerial gunning hour were positively …

Investigation Of Van Gogh-Like 2 Mrna Regulation And Localisation In Response To Nociception In The Brain Of Adult Common Carp (Cyprinus Carpio), Siobhan C. Reilly, Anja Kipar, David J. Hughes, John P. Quinn, Andrew R. Cossins, Lynne U. Sneddon
Veterinary Science and Medicine Collection
The Van Gogh-like 2 (vangl2) gene is typically associated with planar cell polarity pathways, which is essential for correct orientation of epithelial cells during development. The encoded protein of this gene is a transmembrane protein and is highly conserved through evolution. Van Gogh-like 2 was selected for further study on the basis of consistent regulation after a nociceptive stimulus in adult common carp and rainbow trout in a microarray study. An in situ hybridisation was conducted in the brain of mature common carp (Cyprinus carpio), 1.5 and 3 h after a nociceptive stimulus comprising of an acetic acid injection to …
Genetic Relationship Between Longevity And Objectively Or Subjectively Assessed Performance Traits In Sheep Using Linear Censored Models, W. Mekkaway, Rainer Roehe, Ronald M. Lewis, M. H. Davies, L. Bünger, G. Simm, W. Haresign
Genetic Relationship Between Longevity And Objectively Or Subjectively Assessed Performance Traits In Sheep Using Linear Censored Models, W. Mekkaway, Rainer Roehe, Ronald M. Lewis, M. H. Davies, L. Bünger, G. Simm, W. Haresign
Department of Animal Science: Faculty Publications
Genetic parameters of longevity in crossbred mule ewes, and genetic relationships among longevity, growth, body composition, and subjectively assessed traits on mule lambs and ewes have been estimated using Bayesian linear censored models. Additionally, the genetic associations between longevity and culling reasons were examined. Data comprised 1,797 observations of mule ewes for longevity, culling reasons, growth, body composition, mouth scores, and type traits. Longevity was defined as the time (in years) from 2 yr of age (the age at first lambing of most ewes) to culling or death. Censored data (i.e., observations for which only the lower bound of the …
Assessing Animal Welfare: Different Philosophies, Different Scientific Approaches, David Fraser
Assessing Animal Welfare: Different Philosophies, Different Scientific Approaches, David Fraser
Assessment of Animal Welfare Collection
Attempts to improve animal welfare have commonly centered around three broad objectives: (1) to ensure good physical health and functioning of animals, (2) to minimize unpleasant ‘‘affective states’’ (pain, fear, etc.) and to allow animals normal pleasures, and (3) to allow animals to develop and live in ways that are natural for the species. Each of these objectives has given rise to scientific approaches for assessing animal welfare. An emphasis on health and functioning has led to assessment methods based on rates of disease, injury, mortality, and reproductive success. An emphasis on affective states has led to assessment methods based …
The Development And Role Of Peripheral Auditory Structures In Otocinclus Affinis, Sri Kiran Kumar Reddy Botta
The Development And Role Of Peripheral Auditory Structures In Otocinclus Affinis, Sri Kiran Kumar Reddy Botta
Masters Theses & Specialist Projects
Loricariidae is a very diverse family of catfishes found primarily in the Amazon River basin. These catfishes have a unique characteristic feature of having fenestrae (holes) in the skull region (compound pterotic bone) adjacent to their bi-lobed swim bladder. Since the swim bladders and the compound pterotic may act as an external ear for hearing in this taxon, I hypothesized that these swim bladders structures have an acoustical functional in the loricariid Otocinclus affinis. In order to understand the development of these structures in O. affinis, I first monitored the ontogeny of the compound pterotic bone by clearing …
Pain Perception In Fish: Indicators And Endpoints, Lynne U. Sneddon
Pain Perception In Fish: Indicators And Endpoints, Lynne U. Sneddon
Aquaculture Collection
Recent evidence has shown that fish display aversive behavioral and physiological reactions and a suspension of normal behavior in response to noxious stimuli that cause pain in other animals and humans. In addition to these behavioral responses, scientists have identified a peripheral nociceptive system and recorded specific changes in the brain activity of fish during noxious stimulation. As a result of these observations teleost fish are now considered capable of nociception and, in some opinions, pain perception. From both an experimental and an ethical perspective, it is important that scientists be able to assess possible pain and minimize discomfort that …

Migration Dynamics Of The Northern Saw-Whet Owl In The Piedmont, Mountain, And Coastal Plain Provinces Of Virginia, Kyle E. Van Althuis
Migration Dynamics Of The Northern Saw-Whet Owl In The Piedmont, Mountain, And Coastal Plain Provinces Of Virginia, Kyle E. Van Althuis
Senior Honors Theses
The Northern Saw-whet Owl (Aegolius acadicus) is a small common owl of which little is known. The saw-whet’s migration dynamics are particularly shrouded in mystery due to the secretive nature of this owl. This study examined data obtained by capturing owls with mist nets in order to better understand volume, timing, sex differences and age differences in migration in the Piedmont province of Virginia for 2002-2007. Comparative owl capture data from two other physiographic regions (Mountain and Coastal Plain) were also examined.
Migration flight volume was highest in the Mountain province and lowest in the Coastal Plain, while movements were …
Response To Displaced Neighbours In A Territorial Songbird With A Large Repertoire, Elodie F. Briefer, Thierry Aubin, Fanny Rybak
Response To Displaced Neighbours In A Territorial Songbird With A Large Repertoire, Elodie F. Briefer, Thierry Aubin, Fanny Rybak
Ethology Collection
Neighbour recognition allows territory owners to modulate their territorial response according to the threat posed by each neighbour and thus to reduce the costs associated with territorial defence. Individual acoustic recognition of neighbours has been shown in numerous bird species, but few of them had a large repertoire. Here, we tested individual vocal recognition in a songbird with a large repertoire, the skylark Alauda arvensis. We first examined the physical basis for recognition in the song, and we then experimentally tested recognition by playing back songs of adjacent neighbours and strangers. Males showed a lower territorial response to adjacent neighbours …

Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin
Bioacoustics Collection
The automatic recognition of animal sounds is one of the powerful techniques for replacing the traditional ecological survey method that mainly depends on manpower, which is hence both costly and time consuming. This study developed an automatic frog call recognition system based on the combination of a pre-classification method of the syllable lengths and a multi-stage average spectrum (MSAS) method. In this system, the input frog syllables are first classified into one of the four groups determined by the pre-classification method according to syllable length. Then the proposed MSAS method is used to extract the standard feature template to analyze …

Biofuels: Cultivating Energy, not Invasive Species, approved by ISAC on August 11, 2009
ISSUE
To provide alternatives to petroleum-based energy, the United States government has mandated a greater proportion of plant-based biofuels be integrated into its energy portfolio. However, certain plant species being proposed for biofuel production in the United States are invasive species or are likely to escape cultivation and become invasive. United States Executive Order (EO) 131121 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states: “Each Federal agency whose actions …

Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott
Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott
Veterinary Science and Medicine Collection
Many studies of sexually selected vocal communication assume that calls remain stable throughout the breeding season. However, during this period, physiological and social factors change and these can have strong effects on the structure of calls and calling rates. During the rut, fallow bucks, Dama dama, reduce their feeding and increase the time and energy spent on vocalizing and fighting to gain matings, and consequently their body condition declines greatly. The availability of matings and intensity of competition between males also change. Therefore, we predicted that male vocal signalling would vary over time in response to the changing intersexual and …

Varroa In The Aloha State, Tammy Horn
Varroa In The Aloha State, Tammy Horn
Tammy Horn
The Hawaiian word for fate is hopena, and since the early 1900s, it’s been a matter of hopena that Varroa mites would eventually come to the Islands. The inevitability increased in 2001 when APHIS/USDA forced Hawai’i to allow transshipments of queens and package bees from New Zealand to Canada to pass through its ports. Since Varroa arrived on Oahu in 2006 and on the Big Island in 2008, many agencies have been working together to create appropriate infrastructure to address the latest arrival. According to Hawai’i Department of Agriculture (HDOA) branch chief Neil Reimer, 'Before Varroa showed up in Hawai’i, …
Fort Richardson Ordnance Detonations And The Harbor Porpoise: A Case Study In Marine Mammal Bioacoustics, Heather Heenehan
Fort Richardson Ordnance Detonations And The Harbor Porpoise: A Case Study In Marine Mammal Bioacoustics, Heather Heenehan
Honors Scholar Theses
Hearing is extremely important for cetaceans because it is their “principal sense” (Weilgart, 2007) thus the harbor porpoise and other marine animals are highly dependent on sound for survival. This is why we should care about the impact of noise on animals like the harbor porpoise. Since sound travels so well in water, an explosion, sonar, boat noise, etc. can affect a very large area and thus many different species of marine mammals. Although military actions such as low frequency sonar have made recent news, noise has been affecting cetaceans, especially beaked whales, since at least 1991 (Weilgart, 2007).

Characterizing The Role Of Phaeobacter In The Mortality Of The Squid, Euprymna Scolopes, Brian Shawn Wong Won
Characterizing The Role Of Phaeobacter In The Mortality Of The Squid, Euprymna Scolopes, Brian Shawn Wong Won
Honors Scholar Theses
The subject of our study is the Hawaiian bobtail squid, Euprymna scolopes, which is known for its model symbiotic relationship with the bioluminescent bacterium, Vibrio fischeri. The interactions between E. scolopes and V. fischeri provide an exemplary model of the biochemical and molecular dynamics of symbiosis since both members can be cultivated separately and V. fischeri can be genetically modified 1. However, in a laboratory setting, the mortality of embryonic E. scolopes can be a recurrent problem. In many of these fatalities, the egg cases display a pink-hued biofilm, and rosy pigmentation has also been noted in the deaths of …
Time Series Observations Of Species Composition And Behavioral Interactions Of Fish At An Ocean Observatory Off The Coast Of Georgia, Amy E. Paquette
Time Series Observations Of Species Composition And Behavioral Interactions Of Fish At An Ocean Observatory Off The Coast Of Georgia, Amy E. Paquette
Honors Scholar Theses
The use of ocean observatories is expanding with the potential for collecting serial data with high temporal resolution at multiple sites within an ecosystem. Integration of underwater video cameras in observatory systems allow observation of vagile species and are useful tools for observing variations in behavior over time. In order to assess the utility of using video records for time series behavioral data I analyzed video records from an observatory site in the South Atlantic Bight (SAB) off the Coast of Georgia collected during the month of November in 2000, 2002 and 2004. Data were used to quantify annual variation …
Animal Behaviour, Animal Welfare And The Scientific Study Of Affect, David Fraser
Animal Behaviour, Animal Welfare And The Scientific Study Of Affect, David Fraser
Emotion Collection
Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect for both philosophical and methodological reasons. Philosophically, under the influence of Positivism many scientists considered that the affective states of animals fall outside the scope of science. Certain methodological features of the research also favoured explanations that did not involve affect. The features included the tendency to rely on abstract, quantitative measures …
Effects Of Direct And Indirect Predator Cues On Heteromyid Seed Selection And Seed Fate, Kelly J. Sivy
Effects Of Direct And Indirect Predator Cues On Heteromyid Seed Selection And Seed Fate, Kelly J. Sivy
Undergraduate Honors Capstone Projects
Many factors affect foraging behavior of rodents, including predation risk, which is thought to influence seed selection and seed handling by desert rodents in patchy environments. Understanding forces that drive seed selection and seed fate can aid understanding of rodents' impacts on vegetation structure and dynamics. In a feeding arena study, we tested how indirect and direct predation cues influence seed selection and handling behaviors (e.g., scatterhoarding and larderhoarding) of two heteromyid rodents, Dipodomys ordii (Ord's kangaroo rat) and Perognathus parvus (Great Basin pocket mouse), foraging on three seed species. The indirect cue was shrub cover: one half of the …
Animal Pleasure And Its Moral Significance, Jonathan Balcombe
Animal Pleasure And Its Moral Significance, Jonathan Balcombe
Sentience Collection
This paper presents arguments for, and evidence in support of, the important role of pleasure in animals’ lives, and outlines its considerable significance to humankind’s relationship to other animals. In the realms of animal sentience, almost all scholarly discussion revolves around its negative aspects: pain, stress, distress, and suffering. By contrast, the positive aspects of sentience – rewards and pleasures – have been rarely broached by scientists. Yet, evolutionary principles predict that animals, like humans, are motivated to seek rewards, and not merely to avoid pain and suffering. Natural selection favours behaviours that enhance survival and procreation. In the conscious, …
Wild Justice - Honor And Fairness Among Beasts At Play, Marc Bekoff, Jessica Pierce
Wild Justice - Honor And Fairness Among Beasts At Play, Marc Bekoff, Jessica Pierce
Social Cognition Collection
This essay challenges science’s traditional taboo against anthropomorphizing animals or considering their behavior as indicative of feelings similar to human emotions. In their new book Wild Justice: The Moral Lives of Animals, the authors argue that anthropomorphism is alive and well, as it should be. Here they describe some activities of animals, particularly animals at play, as clear signs that they have recognizable emotions and moral intelligence. Based on years of behavioral and cognitive research, the authors discuss in their book that animals exhibit a broad repertoire of moral behaviors, including empathy and cooperation, but here they concentrate on the …

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon
Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon
Aquaculture Collection
A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …
