First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith 2019 University of Southern Mississippi

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The first occurrence ...


Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes 2018 Liberty University

Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes

Senior Honors Theses

African Wild Dogs (Lycaon pictus) are an endangered species of canid from Sub-Saharan Africa. They are very social communal hunters, and are capable of chasing down prey for long stretches of time. Wild dogs benefit a savannah ecosystem by regulating the populations of their prey so that it does not become unhealthy and overgrown. Like many organisms, wild dogs are also in competition with other predators for resources, namely lions and hyenas, who are capable of stealing their kills and occasionally injuring and killing them. Due to the depletion of their wild prey, wild dogs may also prey upon farmers ...


The Effect Of Rem Sleep Deprivation On Spatial Memory In Male And Female Rats, Kaitlyn Heywood 2018 Seton Hall University

The Effect Of Rem Sleep Deprivation On Spatial Memory In Male And Female Rats, Kaitlyn Heywood

Seton Hall University Dissertations and Theses (ETDs)

It is important for an organism to excel in spatial memory abilities. An organism’s survival is dependent on their ability to navigate through their environment to find resources, such as food and water, while being able to navigate home safely. With how important it is to navigate an environment safely, it is important to investigate things that impact spatial memory, such as rapid eye movement (REM) sleep deprivation. Sleep research has primarily utilized male rodents to model sleep disturbances studies which cannot be easily studied in human participants. Research has been divided on whether four hours of REM sleep ...

Searching Images And The Meaning Of Alarm Calls, Alan B. Bond 2018 University of Nebraska-Lincoln

Searching Images And The Meaning Of Alarm Calls, Alan B. Bond

Alan Bond Publications

The snake alarm call of Japanese tits prompts nesting adults to search for and mob the reptile until it is driven away. From playback experiments, Suzuki (2018) has inferred that the call provides an associative cue, evoking a searching image of the salient visual features of the predator—a novel approach to exploring visual attention and vocal communication in the wild.


Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Monica Padilla de la Torre, Christian Nawroth 2018 Queen Mary University of London

Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Monica Padilla De La Torre, Christian Nawroth

Emotion

Emotions can be defined as an individual’s affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other’s emotional states, a process labeled as “emotional contagion.” Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective ...


Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth 2018 Leibniz Institute for Farm Animal Biology

Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth

Social Cognition

In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other reference persons can influence human–animal interaction at different levels and over different periods of time. In this study, we investigated human-directed behaviour in the ‘unsolvable task’ paradigm in two groups of domestic goats (Capra aegagrus hircus). One group was positively handled and habituated to a plastic box by the experimenter to retrieve a food reward, while the other group only ...


Allomaternal Care By Conspecifics Impacts Activity Budgets Of Colobus Guereza Mothers, Dominique L. Raboin 2018 CUNY Hunter College

Allomaternal Care By Conspecifics Impacts Activity Budgets Of Colobus Guereza Mothers, Dominique L. Raboin

School of Arts & Sciences Theses

In primate societies, caring for infants involves nursing, protection, provisioning, and carrying - all energetically taxing states for mothers. The cost of holding and carrying clinging infants often constrains mothers from moving and traveling, potentially reducing their food and energy intake. Alternatively, when an infant is physically separated from their mother they are at risk of predation from birds of prey or other large mammals. This requires a high level of vigilance from mothers, often further deterring them from acquiring the food and energy that they need. Allomaternal care (AMC) is hypothesized to provide mothers with a way to safely detach ...


An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi 2018 CUNY Hunter College

An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi

School of Arts & Sciences Theses

The investigator attempted to predict the vocal learning propensity from either family pedigree or early vocal babbling (subsong). Pedigree trees suggest the possibility that vocal learning ability may depend on family. We failed to predict vocal learning propensity from subsong, but suggested that subsong may influence vocal learning outcome.


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor 2018 The University of Southern Mississippi

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard (Gardner & Gardner, 1969; Rumbaugh, 1977; Savage-Rumbaugh, 1986). Savage-Rumbaugh decided to take a different approach to learning after one individual demonstrated the ability to use the keyboard ...


Assessment Of A Nutritional Rehabilitation Model In Two Modern Broilers And Their Jungle Fowl Ancestor: A Model For Better Understanding Childhood Undernutrition, Mikayla Baxter 2018 University of Arkansas, Fayetteville

Assessment Of A Nutritional Rehabilitation Model In Two Modern Broilers And Their Jungle Fowl Ancestor: A Model For Better Understanding Childhood Undernutrition, Mikayla Baxter

Theses and Dissertations

The World Health Organization, estimated that 22.9% of children under the age of 5 are stunted. The etiology of stunting is multifactorial and is associated with poor linear growth, villous atrophy, dysbiosis, and increased intestinal permeability. Inclusion of rye in poultry diets induces nutrient deficiencies and increases intestinal permeability, dysbiosis and decreases growth rates. The objective of this dissertation was to determine if chickens consuming a rye based diet exhibited a similar pathophysiology of stunted children to develop a relevant animal model. Therefore, early or late phase malnutrition was induced determine the effects of malnutrition on performance, bone mineralization ...


Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning 2018 University of Arkansas, Fayetteville

Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning

Theses and Dissertations

Fescue toxicosis in grazing beef cattle is caused by consumption of Ergot alkaloids associated with tall fescue (toxic fescue) and is responsible for substantial economic loss to the U.S. beef industry. Cattle consuming toxic fescue suffer adverse physiological responses, such as: hyperthermia, increased respiration rate (RR), poor reproduction and growth performance. Other adverse responses to fescue toxins include the retention of a winter hair coat and vasoconstriction in the extremities, which can lead to tissue necrosis. Identifying cattle with reduced susceptibility to fescue toxins would allow for efficient use of fescue pastures; thus, the objectives of this thesis was ...


Report On Owned Dog Population Survey In Lingayen, Philippines, Tamara Kartal, Lynne U. Sneddon, Amit Chaudhari 2018 Humane Society International

Report On Owned Dog Population Survey In Lingayen, Philippines, Tamara Kartal, Lynne U. Sneddon, Amit Chaudhari

Demography and Statistics for Companion Animal Populations

The Philippines is among the Southeast Asian countries that has a long-standing problem with rabies. About 200 people die of rabies each year in the Philippines, and most are attributed to dog bite cases (Deray, 2015). The sources of infection of more than 95% of human rabies cases worldwide have been reported to be domestic dogs (Cleaveland, et al., 2006). Focusing on the main source rather than the human population, is therefore, the best strategy to eliminate rabies. The World Health Organization (WHO) recommends covering at least 70% of the existing domestic dog population with rabies vaccination in the shortest ...

Companion Animal Statistics In The Usa, Andrew N. Rowan 2018 The Humane Society of the United States

Companion Animal Statistics In The Usa, Andrew N. Rowan

Demography and Statistics for Companion Animal Populations

Early in 2008, a number of organizations and individuals interested in accurate statistics on pet population numbers and trends gathered in a hotel in Houston, TX to review the available data on estimated pet populations and shelter demographics. While the data and analysis below was produced and subsequently added to by just one of those individuals, the following document takes into account the input from those who attended. For example, it was generally accepted that the AVMA pet population estimates from their quinquennial surveys are likely to be more reliable than the biennial surveys used to produce the APPMA demographic ...


Subjective Measures Of Temperament In Beef Heifers Are Reliable Indicators Of Physiological Stress And Indicate Acclimation To Repeated Handling, Jamie Parham 2018 University of Nebraska - Lincoln

Subjective Measures Of Temperament In Beef Heifers Are Reliable Indicators Of Physiological Stress And Indicate Acclimation To Repeated Handling, Jamie Parham

Theses and Dissertations in Animal Science

Associations between excitable temperament and many economically relevant traits have been established. In being heritable, temperament can be augmented through selection. Current methods to evaluate temperament in a production setting include numerous subjective and objective measurements, which some producers may find cumbersome to navigate. Those who utilize these methods may not do so efficiently if selection criteria are not indicative of an animal's response to stress, or initial evaluations are not strong indicators of future temperament. The objectives of this research were to develop a procedure for evaluation of calf behavior, indicative of physiological stress, and then determine whether ...


Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. McElligott 2018 Queen Mary University of London

Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott

Social Cognition

Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall ...


Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth 2018 Agroscope Tänikon

Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth

Spatial Cognition

Horses’ ability to adapt to new environments and to acquire new information plays an important role in handling and training. Social learning in particular would be very adaptive for horses as it enables them to flexibly adjust to new environments. In the context of horse handling, social learning from humans has been rarely investigated but could help to facilitate management practices. We assessed the impact of human demonstration on the spatial problem-solving abilities of horses during a detour task. In this task, a bucket with a food reward was placed behind a double-detour barrier and 16 horses were allocated to ...
