Indicators Of Age, Body Size And Sex In Goat Kid Calls Revealed Using The Source–Filter Theory, Alan Mcelligott, Elodie Briefer

Animal Sentience, Intelligence, and Emotion

The source–filter theory is an important framework recently applied to the study of animal vocalisations, which links the mode of vocal production to call parameters. Vocalisations can be good indicators of a sender’s characteristics, such as identity, body size, age, and even hormonal status and affective states. For these reasons, applied vocal communication research would greatly benefit from adopting the source–filter theory approach to identify key call parameters linked to physical and physiological characteristics of domestic animals. Here, we introduce the source–filter theory through a detailed analysis and interpretation of goat contact calls during development. In mammals, vocal development is …

The Case For Animal Rights

Animal Welfare and Animal Protection

In the space I have at my disposal here I can only sketch, in the barest outline, some of the main features of the book Its main themes-and we should not be surprised by this-involve asking and answering deep, foundational moral questions about what morality is, how it should be understood, and what is the best moral theory, all considered. I hope I can convey something of the shape I think this theory takes. The attempt to do this will be (to use a word a friendly critic once used to describe my work) cerebral, perhaps too cerebral. But this …

Influence Of Rock-Pool Characteristics On The Distribution And Abundance Of Inter-Tidal Fishes, Culum Brown, Gemma White, Gemma White

Ecology, Habitat, and Land Management

Rock pools can be found in inter-tidal marine environments worldwide; however, there have been few studies exploring what drives their, fish species composition, especially in Australia. The rock-pool environment is highly dynamic and offers a unique natural laboratory to study the habitat choices, physiological limitations and adaptations of inter-tidal fish species. In this study rock pools of the Sydney region were sampled to determine how the physical (volume, depth, rock cover and vertical position) and biological (algal cover and predator presence) parameters of pools influence fish distribution and abundance. A total of 27 fish species representing 14 families was observed …

Harry F. Harlow And Animal Research: Reflection On The Ethical Paradox, John Gluck

Animal Research, Testing, and Experimentation

With respect to the ethical debate about the treatment of animals in biomedical and behavioral research, Harry F. Harlow represents a paradox. On the one hand, his work on monkey cognition and social development fostered a view of the animals as having rich subjective lives filled with intention and emotion. On the other, he has been criticized for the conduct of research that seemed to ignore the ethical implications of his own discoveries. The basis of this contradiction is discussed and propositions for current research practice are presented.

Thinking Pigs: Cognition, Emotion, And Personality, Lori Marino

Mammalogy

An exploration of the cognitive complexity of Sus domesticus, the domestic pig.

An Hsus Report: Welfare Issues With Genetic Engineering And Cloning Of Farm Animals

HSUS Reports: Farm Industry Impacts on Animals

Developments in biotechnology have raised new concerns about animal welfare, as farm animals now have their genomes modified (genetically engineered) or copied (cloned) to propagate certain traits useful to agribusiness, such as meat yield or feed conversion. These animals suffer from unusually high rates of birth defects, disabilities, and premature death.

Commmunity, Ecology, And Modernity: Faunal Analysis Of Skútustaðir In Mývatnssveit, Northern Iceland, Megan Hicks

All Dissertations, Theses, and Capstone Projects

The dissertation examines the archaeofaunal remains from Skútustaðir, a middle to high-status farm in Mývatnssveit, Northern Iceland, to understand the experience of rural communities and their ecologies during Iceland’s transition from regulated colonial exchange to a capitalist economy during the 17^th through 19^th centuries. Archaeofaunal analysis is used to reconstruct changes in the ways that people herded, hunted, fished, providing insights into how they managed their local environments for subsistence and novel contexts of exchange. In addition to archaeofaunal analysis, primary textual sources are explored to assess how the Skútustaðir household and its rural community mobilized long-term knowledge …

Characteristics Of Non-Fatal Attacks By Black Bears: Conterminous United States, 2000–2017, Cady Sartini, Shawn Crimmins, Scott Hygnstrom, Janel Scharhag, Jeffrey Stetz

Human–Wildlife Interactions

Attacks on humans by bears (Ursus spp.) have increased in recent decades, as both human and bear populations have increased. To help mitigate the risk of future attacks, it is important to understand the circumstances in past attacks. Information and analyses exist regarding fatal attacks by both American black bears (Ursus americanus) and brown bears (U. arctos) as well as non-fatal attacks by brown bears. No similarly thorough analyses on non-fatal attacks by black bears are available. Our study addressed this information gap by analyzing all (n = 210) agency-confirmed, non-fatal attacks by black …

A Scientific Conception Of Animal Welfare That Reflects Ethical Concerns, David Fraser, Edmond Pajor, E. Pajor, B. Milligan, Barry Milligan, Daniel Weary, Daniel Weary

Ethics and Animal Welfare

Scientific research on 'animal welfare' began because of ethical concerns over the quality of life of animals, and the public looks to animal welfare research for guidance regarding these concerns. The conception of animal welfare used by scientists must relate closely to these ethical concerns if the orientation of the research and the interpretation of the findings is to address them successfully.

At least three overlapping ethical concerns are commonly expressed regarding the quality of life of animals: (1) that animals should lead natural lives through the development and use of their natural adaptations and capabilities, (2) that animals should …

The Public Health Impacts Of Concentrated Animal Feeding Operations On Local Communities, Michael Greger

Environmental Pollution, Contamination, and Public Health

Large-scale farm animal production facilities, also known as concentrated animal feeding operations (CAFOs), release a significant amount of contaminants into the air and water. Adverse health effects related to exposure to these contaminants among CAFO workers have been welldocumented; however, less is known about their impact on the health of residents in nearby communities. Epidemiological research in this area suggests that neighboring residents are at increased risk of developing neurobehavioral symptoms and respiratory illnesses, including asthma. Additional research is needed to better understand community-scale exposures and health outcomes related to the management practices and emissions of CAFOs.
