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.


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 ...


The Private And Free Roaming Street Dog Population In Coimbatore, Tamil Nadu, India, Tamara Kartal, Amit Chaudhari 2018 Humane Society International

The Private And Free Roaming Street Dog Population In Coimbatore, Tamil Nadu, India, Tamara Kartal, Amit Chaudhari

Stray and Feral Animal Populations

Humane Society International - India (HSI- India) together with Humane Animal Society (HAS) and a team of volunteers conducted two dog population surveys in 100 wards of Coimbatore, India (The 2011 census provides a human population of 10507211; An estimate from 2017 estimates a human population of 18900002). The first was a street dog survey and the other was a household survey of the private (pet) dog population and their owners.


Variables Affecting Latency Of Rats Running On A Maze, Divya Subramanian 2018 University of Connecticut

Variables Affecting Latency Of Rats Running On A Maze, Divya Subramanian

Honors Scholar Theses

When rats are running on a maze, what factors affect their latency? This project examines how time of day of training and hunger levels of the rats affect how long they take to complete the sessions of a behavioral task. A training day consists of three sessions, each with 20 runs. I hypothesize that the rats’ performance will improve if they are trained later in the day, if they are hungrier, and in successive sessions.

How To Help When It Hurts? Think Systemic, Corey L. Wrenn 2018 The Animal Studies Repository

How To Help When It Hurts? Think Systemic, Corey L. Wrenn

Corey Lee Wrenn, Ph.D.

To resolve a moral dilemma created by the rescue of carnivorous species from exploitative situations who must rely on the flesh of other vulnerable species to survive, Cheryl Abbate applies the guardianship principle in proposing hunting as a case-by-case means of reducing harm to the rescued animal as well as to those animals who must die to supply food. This article counters that Abbate’s guardianship principle is insufficiently applied given its objectification of deer communities. Tom Regan, alternatively, encouraged guardians to think beyond individual dilemmas and adopt a measure of systemic reconstruction, that being the abolition of speciesist institutions ...


Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter 2018 University of Arkansas, Fayetteville

Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter

Animal Science Undergraduate Honors Theses

A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Further growth performance data were analyzed during different phases of the nursery stage. Overall, no effect of teat order was found on average daily gain, average ...


Dog Population & Dog Sheltering Trends In The United States Of America, Andrew N. Rowan, Tamara Kartal 2018 The Humane Society of the United States

Dog Population & Dog Sheltering Trends In The United States Of America, Andrew N. Rowan, Tamara Kartal

Demography and Statistics for Companion Animal Populations

Dog management in the United States has evolved considerably over the last 40 years. This review analyzes available data from the last 30 to 40 years to identify national and local trends. In 1973, The Humane Society of the US (The HSUS) estimated that about 13.5 million animals (64 dogs and cats per 1000 people) were euthanized in the US (about 20% of the pet population) and about 25% of the dog population was still roaming the streets. Intake and euthanasia numbers (national and state level) declined rapidly in the 1970s due to a number of factors, including the ...


Effects Of Norharmane And Nicotine On The Conditioned Place Preference Of Mice, Lindsey Galbo 2018 Northern Michigan University

Effects Of Norharmane And Nicotine On The Conditioned Place Preference Of Mice, Lindsey Galbo

All NMU Master's Theses

Tobacco smoking in the United States is used by approximately 25% of adults. Many studies using animal models have suggested that nicotine has rewarding properties. Contrastingly, several studies have also found it to be a weakly reinforcing substance at low and high dose levels. Due to this, other tobacco constituents, such as the monoamine oxidase inhibitor norharmane which is found in tobacco leaf and smoke, may be responsible for tobacco addiction by potentiating the rewarding properties of nicotine. Several studies have attempted to observe this phenomenon, however, monoamine oxidase inhibitors that are not found in tobacco leaf or smoke have ...


Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas 2018 University of Rhode Island

Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas

Senior Honors Projects

Animal welfare is one of the most important parts of animal management. Apart from other measures of good animal welfare, like being in good health, animal behavior can be indicative of the animal’s internal state and is often one of the first signs of improper welfare. Stereotypies, or stereotypic behavior, are commonly viewed as a symptom of improper animal welfare. Unenriched, or barren, environments associated with farmed livestock have long been associated with inducing stereotypic behavior. The addition of precise enrichment to the animals’ environment is a common remedy for stereotypic behavior. With respect to stereotypic goat behavior, few ...
