Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott

Learning Ability Collection

Variation in common personality traits, such as boldness or exploration, is often associated with risk–reward trade–offs and behavioural flexibility. To date, only a few studies have examined the effects of consistent behavioural traits on both learning and cognition. We investigated whether certain personality traits (‘exploration’ and ‘sociability’) of individuals were related to cognitive performance, learning flexibility and learning style in a social ungulate species, the goat (Capra hircus). We also investigated whether a preference for feature cues rather than impaired learning abilities can explain performance variation in a visual discrimination task. We found that personality scores were consistent …

A Moral Argument For Veganism, Dan Hooley, Nathan Nobis

Human Health Collection

In this essay, we argue for dietary veganism. Our case has two steps. First, we argue that, in most circumstances, it is morally wrong to raise animals to produce meat, dairy products, most eggs (a possible exception we discuss is eggs from pet chickens) and most other animal food products. Turning animals into food, and using them for their byproducts, causes serious harms to animals that are morally unjustified: that is, the reasons given to justify causing these kinds of harms – goods or alleged goods that result from animal farming and slaughter – are inadequate to justify the bad …

Use Of Qualitative Behaviour Assessment As An Indicator Of Welfare In Donkeys, Michela Minero, Emanuela Dalla Costa, Francesca Dai, Leigh Anne Margaret Murray, Elisabetta Canali, Françoise Wemelsfelder

Animal Welfare Collection

One of the objectives of the Animal Welfare Indicators project was to develop animal-based indicators to assess donkey welfare, including their emotional state. This study aimed to develop a fixed rating scale of Qualitative Behaviour Assessment (QBA) for donkeys, to evaluate the inter-observer reliability when applied on-farm, and to assess whether the QBA outcomes correlate to other welfare measures.

A fixed list of 16 descriptors was designed on the basis of a consultation in a focus group. The fixed list was then used by four trained observers to score nine 2 min videos of groups of donkeys owned by six …

Mating Games Squid Play: Reproductive Behaviour And Sexual Skin Displays In Caribbean Reef Squid Sepioteuthis Sepioidea, Jennifer Mather

Reproductive Behavior Collection

Observation of the sexual interactions of Sepioteuthis sepioidea squid during the short reproductive stage of their lives showed a scramble competition system, with both male and female polygyny. Mature females were faithful to a specific location in the daytime, whereas males moved from group to group and formed short-term consortships with females. Males defended females from other males, particularly with an agonistic Zebra display. Male–female pairs exchanged Saddle-Stripe displays, after which males might display an on–off Flicker. There was considerable female choice. Only if a female responded to this display with a parallel Rocking action would she pair and would …

Hpi Reactivity Does Not Reflect Changes In Personality Among Trout Introduced To Bold Or Shy Social Groups, Jack S. Thomson, Phillip C. Watts, Tom G. Pottinger, Lynne U. Sneddon

Social Behavior Collection

Physiological stress responses often correlate with personalities (e.g., boldness). However, this relationship can become decoupled, although the mechanisms underlying changes in this relationship are poorly understood. Here we quantify (1) how an individual’s boldness (response to novel objects) in rainbow trout, Oncorhynchus mykiss, changes in response to interactions with a population of either bold or shy conspecifics and we (2) measured associated post-stress cortisol levels. Initially-bold trout became shyer regardless of group composition, whereas shy trout remained shy demonstrating that bold individuals are more plastic. Stress-induced plasma cortisol reflected the original personality of fish but not the personality induced …

Dry Period Plane Of Energy: Effects On Glucose Tolerance In Transition Dairy Cows, S. Mann, F. A. Leal Yepes, M. Duplessis, J. J. Wakshlag, T. R. Overton, B. P. Cummings, D. V. Nydam

Physiology Collection

Overfeeding energy in the dry period can affect glucose metabolism and the energy balance of transition dairy cows with potential detrimental effects on the ability to successfully adapt to early lactation. The objectives of this study were to investigate the effect of different dry cow feeding strategies on glucose tolerance and on resting concentrations of blood glucose, glucagon, insulin, nonesterified fatty acids (NEFA), and β-hydroxybutyrate (BHB) in the peripartum period. Cows entering second or greater lactation were enrolled at dry-off (57 d before expected parturition) into 1 of 3 treatment groups following a randomized block design: cows …

Body Condition Score And Plane Of Nutrition Prepartum Affect Adipose Tissue Transcriptome Regulators Of Metabolism And Inflammation In Grazing Dairy Cows During The Transition Period, M. Vailati-Riboni, M. Kanwal, O. Bulgari, S. Meier, N. V. Priest, C. R. Burke, J. K. Kay, S. Mcdougall, M. D. Mitchell, C. G. Walker, M. Crookenden, A. Heiser, J. R. Roche, J. J. Loor

Physiology Collection

Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × …

Geographic Variability Of Octopus Insularis Diet: From Oceanic Island To Continental Populations, Tatiana S. Leite, Allan T. Batista, Françoise D. Lima, Jaciana C. Barbosa, Jennifer A. Mather

Habitat and Trophic Ecology Collection

A predator’s choice of prey can be affected by many factors. We evaluated various influences on population dietary composition, individual specialization and size of prey in Octopus insularis populations from 2 continental and 4 insular locations. We expected that habitat diversity would lead to diet heterogeneity. Furthermore, in keeping with MacArthur & Wilson’s (1967) theory of island biogeography, we expected that diet diversity would be lower around islands than on the coast of the mainland. Both predictions were confirmed when prey remains from octopus middens were examined. The 2 continental areas exhibited a richer habitat diversity and a wider variety …

Intertemporal Similarity: Discounting As A Last Resort, Jeffrey R. Stevens

Jeffrey Stevens Publications

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, Leland (2002) and Rubinstein (2003) propose models that 1) compare the two reward amounts to determine whether they are similar, 2) compare the similarity of the two time delays, and then 3) make a decision based on these similarity judgments. Here, I tested discounting models against attribute-based …

Voluntary Food Sharing In Pinyon Jays: The Role Of Reciprocity And Dominance, Juan F. Duque, Jeffrey R. Stevens

Jeffrey Stevens Publications

Food sharing offers a clear example of prosocial behavior, in which one individual’s actions benefit another. Researchers have proposed a range of hypotheses that explain why food sharing may occur among unrelated individuals. Two such hypotheses, reciprocity and dominance, have been tested in many species, including fish, corvids, rats, bats, and primates, showing that (1) recipients sometimes reciprocate sharing back to previous donors and (2) dominant individuals share more than subordinates. Although primates dominate the study of prosocial behavior, active donation of food is actually quite rare in primates. In contrast, several corvid species spontaneously share food much more frequently. …

The Domain Specificity Of Intertemporal Choice In Pinyon Jays, Jeffrey R. Stevens, Bryce Kennedy, Dina Morales, Marianna Burks

Jeffrey Stevens Publications

When choosing between a piece of cake now versus a slimmer waistline in the future, many of us have difficulty with self-control. Food-caching species, however, regularly hide food for later recovery, sometimes waiting months before retrieving their caches. It remains unclear whether these long-term choices generalize outside of the caching domain. We hypothesized that the ability to save for the future is a general tendency that cuts across different situations. To test this hypothesis, we measured and experimentally manipulated caching to evaluate its relationship with operant measures of self-control in pinyon jays (Gymnorhinus cyanocephalus). We found no correlation …

Wildlife And Local Community Investigation In Trans-Boundary Area Between China-Mongolia Borders, Weikang Yang, Wenxuan Xu, Canjun Xia, Wei Liu, Xingyi Gao

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During June 2008, and August and December 2010, we investigated both the status of wildlife and local human communities in the great Gobi trans-boundary area between China and Mongolia. We surveyed Baytik Mountain (called Baitag Bogdt on the Mongolian side of the border)( 44°59′ - 45°21′N，90°30′ - 90°53′E), which is located in the West of Great Gobi B strict protected area (GGB) and connected with Dzungarian Gobi. The Kazakh shepherds still maintain their nomadic life here in Baytik Mountains. The region was divided into summer, winter and transitional pasture, and most of the livestock were goats and sheep. We also …

Evaluation Of Bison (Bison Bison) Ecology At The Olson’S Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada, Joshua L. Leonard

Electronic Theses and Dissertations

Bison (Bison bison), the largest mammalian species in North America, historically numbering in the tens of millions (Roe 1970, McHugh 1972, Dary 1989, Shaw 1995), was nearly extirpated at the turn of the 19th century (Knapp et al. 1999; Gates et al. 2010). At the time, estimates of less than 1,000 bison remaining in North America are widely accepted (Hornaday 1889; Seton 1927; Gates et al. 2010). The decline of bison includes factors such as disease (Flores 1991; Isenberg 2000), sport hunting (Danz 1997; Dary 1989; Hewitt 1919; Isenberg 2000; McHugh 1972), and unofficially funded commercial hunting by the U.S. …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodríguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Faculty Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …

Use Of Anti-Mullerian Hormone To Select For Fertility In Beef Heifers, Hannah Newberry, Beth Kegley, Charles Rosenkrans, Rick Rorie

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A study was conducted to determine whether concentration of serum Anti-Mullerian Hormone (AMH) at weaning and/or breeding could predict subsequent fertility in beef heifers. Frequency distribution was used to assign serum AMH concentration measured at weaning, breeding, and the change from weaning to breeding into quartiles. Comparison of heifers based on serum AMH quartiles at weaning failed (P ≥ 0.35) to detect any effect of AMH on subsequent heifer cyclicity at breeding, estrous response after synchronization, artificial insemination (AI) pregnancy rate, overall breeding season pregnancy rate, or estimated estrous cycle of the breeding season when conception occurred. Based on AMH …

Current Status Of The Northern Saw-Whet Owl (Aegolius Acadicus) In Arkansas, Mitchell L. Pruitt, Kimberly G. Smith

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The secretive Northern Saw-whet Owl (Aegolius acadicus) is believed to be much more widespread during fall and winter than previously thought. Of the few places in the southern United States conducting research on this species, all have been successful at capturing birds. A total of 12 historic records existed for Arkansas until our work began in fall of 2014. The first confirmed record was in 1959 and the most recent, prior to this research, was in 2010. Over the course of two field seasons, we captured and banded 24 Northern Saw-whet Owls in rural Madison County. All birds were mist-netted …

From Sentience To Science: Limits Of Anthropocentric Cognition, Charukeshi Chandrasekera

Animal Sentience

Donald Broom’s Sentience and Animal Welfare (2014) is an intellectually and morally engaging book written with radical new concepts in mind. It deals with many issues that are central to the animal welfare debate such as brain complexity, cognitive ability, when in life sentience begins, and how it all affects the way we endorse welfare. It addresses how our insatiable quest to define the uniqueness of our own species has led us to ignore logic and scientific evidence. It also brings greater clarity to these precarious positions and outlines pragmatic approaches to tackling this complex topic of sentience and welfare.

Animal Welfare And Animal Rights, M.E. Rolle

Animal Sentience

This overview of Broom’s book, Sentience and Animal Welfare (2014), considers the role the book could play in the animal rights debate. In a thoroughly researched and objectively presented text, Broom lays out information that could place doubt in the minds of decision-makers. By highlighting not just the ways animals resemble humans, but also the ways humans resemble animals, Broom shines a light on a solidly grey area in the animal rights debate.

Reaction To Stimulus Figures In Chimpanzee Drawings, Alexandra Bobrinskoy Casti

All Master's Theses

Seven captive chimpanzees (Pan troglodytes) produced drawings at the University of Oklahoma between November 1971 and November 1972. Chimpanzees drew on sheets of paper that were either blank or had a stimulus. The stimulus was located in the center or offset from the center. These drawings were scanned and digitized. Analysis tested whether chimpanzee mark placement was contingent on the location of stimulus figures. Centroid locations significantly changed between stimulus type for all drawing categories and among participants for free choice and central figure drawings. Participants drew in the empty space opposite offset figure drawings. Findings support previous …

Reflections Of The Social Environment In Chimpanzee Memory: Applying Rational Analysis Beyond Humans, Jeffrey R. Stevens, Julian N. Marewski, Lael J. Schooler, Ian C. Gilby

Jeffrey Stevens Publications

In cognitive science, the rational analysis framework allows modelling of how physical and social environments impose information-processing demands onto cognitive systems. In humans, for example, past social contact among individuals predicts their future contact with linear and power functions. These features of the human environment constrain the optimal way to remember information and probably shape how memory records are retained and retrieved. We offer a primer on how biologists can apply rational analysis to study animal behaviour. Using chimpanzees (Pan troglodytes) as a case study, we modelled 19 years of observational data on their social contact patterns. Much …

Context-Dependent Seed Dispersal By A Scatter-Hoarding Corvid, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison, Alan C. Kamil

Avian Cognition Papers

1. Corvids (crows, jays, magpies and nutcrackers) are important dispersers of large-seeded plants. Studies on captive or supplemented birds suggest that they flexibly adjust their scatter-hoarding behavior to the context of social dynamics and relative seed availability. Because many corvid-dispersed trees show high annual variation in seed production, context-dependent foraging can have strong effects on natural corvid scatter-hoarding behavior.

2. We investigated how seed availability and social dynamics affected scatter-hoarding in the island scrub jays (Aphelocoma insularis). We quantified rates of scatter-hoarding behavior and territorial defense of 26 colormarked birds over a three-year period with variable acorn crops. …

Effects Of Visitors And Enrichments On Behavior Of Captive Red Wolves’ (Canis Rufus) At The Great Plains Zoo, Sioux Falls, South Dakota, Kylee S. Shotkoski

Electronic Theses and Dissertations

Red wolves (Canis rufus) are the first animals to maintain a wild population from captive, released individuals. A captive breeding program for red wolves was started before complete extirpation, and 4 breeding pairs were released in Alligator River National Wildlife Refuge (North Carolina) in 1987 and a small wild population still exists there. Currently, there are several captive breeding facilities for red wolves within the Species Survival Plan (SSP) program. The Great Plains Zoo in Sioux Falls, South Dakota participates in the SSP program. My study was initiated to create a natural history background and evaluate interaction between …

Why Animal Welfarism Continues To Fail, Lori Marino

Animal Sentience

Welfarism prioritizes human interests over the needs of nonhuman animals. Despite decades of welfare efforts other animals are mostly worse off than ever before, being subjected to increasingly invasive and harmful treatments, especially in the factory farming and biomedical research areas. A legal rights-based approach is essential in order for other animals to be protected from the varying ethical whims of our species.

Responses To Familiar And Unfamiliar Humans By Belugas (Delphinapterus Leucas), Bottlenose Dolphins (Tursiops Truncatus), & Pacific White-Sided Dolphins (Lagenorhynchus Obliquidens): A Replication And Extension, Heather M. Hill, Deirdre Yeater, Sarah Gallup, Sara Guarino, Steve Lacy, Tricia Dees, Stan A. Kuczaj Ii

Psychology Faculty Publications

Previous research has documented that cetaceans can discriminate between humans, but the process used to categorize humans still remains unclear. The goal of the present study was to replicate and extend previous work on the discrimination between familiar and unfamiliar humans by three species of cetaceans. The current study manipulated the familiarity and activity level of humans presented to 12 belugas (Delphinapterus leucas) housed between two facilities, five bottlenose dolphins (Tursiops truncatus), and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) during free-swim conditions. Two measures of discrimination were coded from video recordings of each trial: …
