Assessing Anglers Identification Of Common Fish Species Of Nebraska, Jason Reed
Assessing Anglers Identification Of Common Fish Species Of Nebraska, Jason Reed
Department of Environmental Studies: Undergraduate Student Theses
Creel surveys, also known as angler surveys, entail individual interviews with anglers. The interviews include a variety of questions pertaining to their fishing trip on that particular day. The interviewer asks the angler questions that include, but are not limited to what species they caught that day, the size of the fish, how many hours they spent fishing that day, what bait they were using, etc. If the angler does not know the species caught or misidentifies the species there is the potential for the recorded data to negatively impact management techniques that rely on the creel survey data. One …

Molecular Correlates Of Social Dominance: A Novel Role For Ependymin In Aggression, Lynne U. Sneddon, Rupert Schmidt, Yongxiang Fang, Andrew R. Cossins
Ethology Collection
Theoretical and empirical studies have sought to explain the formation and maintenance of social relationships within groups. The resulting dominance hierarchies have significant fitness and survival consequences dependent upon social status. We hypothesised that each position or rank within a group has a distinctive brain gene expression profile that correlates with behavioural phenotype. Furthermore, transitions in rank position should determine which genes shift in expression concurrent with the new dominance status. We used a custom cDNA microarray to profile brain transcript expression in a model species, the rainbow trout, which forms tractable linear hierarchies. Dominant, subdominant and submissive individuals had …

Caffeine Metabolism And Cytochrome P450 Enzyme Mrna Expression Levels Of Genetically Diverse Inbred Mouse Strains, Neal Addicott, Michael Malfatti, Gabriela G. Loots
STAR Program Research Presentations
Cytochrome P450 (CYP) enzymes activate or eliminate medications and other xenobiotics, and Caffeine has been used as an indicator of activity for some CYPs. The natural genetic variation in the human population for caffeine metabolizing CYPs does not yet have an established animal model for comparison, but the natural variation in inbred mouse strains presents an attractive starting point. The project gave four different strains of mice a 40mg/kg dose of caffeine and sampled blood and liver tissue after 30 minutes. Samples were analyzed using High Performance Liquid Chromatography (HPLC), reverse transcription PCR (rtPCR), and quantitative PCR (qPCR). The DBA/2J …
Measurement Of Particle Size Distribution In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Measurement Of Particle Size Distribution In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Faculty Publications
The majority of the research in animal buildings has been on measured concentrations of contaminants that the workers and animals are exposed to; emission measurements have only gained attention in recent years due to potential federal regulations on air quality emissions from animal feeding operations (AFOs). The contribution of AFOs to ambient PM10 and PM2.5 entails reliable measurement of particle size distribution. The objective of this study was to measure and compare the size distribution of particulate matter (PM) at multiple locations inside and at the exhausts of a wean‐to‐finish commercial swine building. The particle size distribution was measured by …
Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang
Faculty Publications
Pollutants, especially dust, are rarely uniformly distributed within ventilated air spaces due to non‐uniform flow fields, particle inertia, gravitational settling, and diffusion. Thus, selecting suitable sampling locations for representative sampling is a challenge. The objective of this study was to determine the spatial and temporal distributions of dust and ammonia concentrations(NH3) in a swine building. Results of this study are useful in the design of sampling strategies that require limited sampling locations and in studying pollutant transport. This study was conducted in a commercial swine building in Illinois. The total suspended particulate (TSP) matter and ammonia concentrations were measured at …

Aquaculture Collection
Bold, risk-taking animals have previously been putatively linked with a proactive stress coping style whereas it is suggested shyer, risk-averse animals exhibit a reactive coping style. The aim of this study was to investigate whether differences in the expression of bold-type behaviour were evident within and between two lines of rainbow trout, Oncorhynchus mykiss, selectively bred for a low (LR) or high (HR) endocrine response to stress, and to link boldness and stress responsiveness with the expression of related candidate genes. Boldness was determined in individual fish over two trials by measuring the latency to approach a novel object. Differences …
Beyond Anthropomorphism: Attributing Psychological Properties To Animals, Kristin Andrews
Beyond Anthropomorphism: Attributing Psychological Properties To Animals, Kristin Andrews
Attitudes Towards Animals Collection
In the context of animal cognitive research, “anthropomorphism” is defined as the attribution of uniquely human mental characteristics to non-human animals. Those who worry about anthropomorphism in research are confronted with the question of which properties are uniquely human. As animals, humans and non-human animals1 share a number of biological, morphological, relational, and spatial properties. In addition, it is widely accepted and humans and animals share some psychological properties such as the ability to fear or desire. These claims about the properties animals share with humans are often the products of empirical work.
Cetaceans And Primates: Convergence In Intelligence And Self-Awareness, Lori Marino
Cetaceans And Primates: Convergence In Intelligence And Self-Awareness, Lori Marino
Sentience Collection
Cetaceans (dolphins, porpoises and whales) have been of greatest interest to the astrobiology community and to those interested in consciousness and selfawareness in animals. This interest has grown primarily from knowledge of the intelligence, language and large complex brains that many cetaceans possess. The study of cetacean and primate brain evolution and cognition can inform us about the contingencies and parameters associated with the evolution of complex intelligence in general, and, the evolution of consciousness. Striking differences in cortical organization in the brains of cetaceans and primates along with shared cognitive capacities such as self-awareness, culture, and symbolic concept comprehension, …
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Sentience Collection
We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.

Sentience Collection
The social milieus of animals can be complex, ranging from almost completely asocial to monogamous pairs (no mean feat) to entire societies. To adapt to a constantly shifting environment of individuals striving toward their own goals, animals appear to have evolved specialized cognitive abilities. As appealing and intuitive as the idea of social cognition is, just defi ning it is diffi cult. We attempted to delineate social cognition, speculate on its adaptive value, and come to an understanding of what we mean when we talk about complexity. Transitive inference was often brought up as an example of a cognitive ability …

Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon
Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon
Veterinary Science and Medicine Collection
Pain assessment in fish is particularly challenging due to their evolutionary distance from humans, their lack of audible vocalization, and apparently expressionless demeanour. However, there are criteria that can be used to gauge whether pain perception occurs using carefully executed scientific approaches. Here, the standards for pain in fish are discussed and can be considered in three ways: neural detection and processing of pain; adverse responses to pain; and consciously experiencing pain. Many procedures that we subject fish to cause tissue damage and may give rise to the sensation of pain. Fish are popular as pets, in animal exhibits, and …
Microdialect And Group Signature In The Song Of The Skylark Alauda Arvensis, Elodie Briefer, Fanny Rybak, Thierry Aubin
Microdialect And Group Signature In The Song Of The Skylark Alauda Arvensis, Elodie Briefer, Fanny Rybak, Thierry Aubin
Sentience Collection
The Skylark Alauda arvensis is a territorial species of open landscape in which pairs settle in stable and adjacent territories during the breeding season. Due to the heterogeneity of the habitat, territories are gathered in patches spaced by a few kilometres, in which each male produces very long and complex flight songs as a part of the territorial behaviour. We showed that, in a given patch, all the males (neighbours) share some particular sequences of syllables in their songs, whereas males settled in different patches (strangers) have almost no sequences in common. Such a phenomenon is known as microdialect. To …

Biochemical Methane Potential Of Different Organic Wastes And Energy Crops From Estonia, M. Luna-Derisco, A. Normak, K. Orupõld
Biochemistry Collection
The biochemical methane potential (BMP) of different Estonian substrates as alternative sources for biogas production was studied. For this purpose, the BMP test was carried out in batch mode at mesophilic temperature (36°C). Substrates were divided into 2 groups: agricultural substrates (silage, hay, cattle and pig slurry) and food industry residues (milk, brewery and cereal industry residues). Methane yields obtained were between 286–319 L kgVS-1 for silage and hay, 238–317 L kgVS-1 for animal slurry and 272–714 L kgVS-1 for agro-industrial wastes. The highest methane yield was obtained from sour cream (714 L kgVS-1), the …

The Canine Sand Maze: An Appetitive Spatial Memory Paradigm Sensitive To Age-Related Change In Dogs, Hannah Salvin, Paul D. Mcgreevy, Perminder S. Sachdev, Michael Valenzuela
Spatial Cognition Collection
Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a …

Male Field Crickets Infested By Parasitoid Flies Express Phenotypes That May Benefit The Parasitoids, Oliver M. Beckers, William E. Wagner
School of Biological Sciences: Faculty Publications
Parasites can cause changes in the phenotypes of their hosts that may benefit the parasite, the host, or both. To understand the evolutionary dynamics of host–parasite interactions it is necessary to first examine the effect of parasitic infestation on the host phenotype and whether the host or parasite benefits from these changes. The fly Ormia ochracea parasitizes the variable field cricket, Gryllus lineaticeps, and it uses male song to locate hosts for its lethal larvae. Adult flies preferentially orient to male songs with faster and longer chirps. We tested the effect of larval infestation on two types of host traits. …
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
All Graduate Theses, Dissertations, and Other Capstone Projects
Invasive plants are a primary contributor to loss of biodiversity worldwide. In southern Minnesota, many wetlands have been invaded by reed canarygrass (Phalaris arundinacea). The current perception among ecologists and resource managers is that these wetlands are of little value to wildlife, yet little is known about the effects on birds of the widespread conversion of diverse wetlands to apparent monocultures of P. arundinacea. The purpose of this study was to determine the effects of P. arundinaceamediated changes in the wetland plant community on avian communities and nesting success. During 2006 and 2007, I studied four diverse sedge wetlands paired …
Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon
Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon
USF Tampa Graduate Theses and Dissertations
Atlantic tarpon are sought after because of their fighting ability on various tackle and support a popular, lucrative and predominantly catch-and-release recreational fishery in Florida. They are not commercially harvested or consumed by the general public, therefore assessing effects of catch-and-release angling on tarpon survival is critical to a sustainable fishery. Tarpon caught on artificial breakaway jig and traditional live bait fishing charters in Boca Grande Pass (n=42) and trips from the recreational fishery of Tampa Bay (n=40) were tagged with ultrasonic transmitters and tracked up to 6 hours immediately following release to estimate post-release mortality. Of the 82 tagged …
Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar
Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar
USF Tampa Graduate Theses and Dissertations
In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil …
