Predators In Natural Fragments: Foraging Ecology Of Wolves In British Columbia’S Central And North Coast Archipelago, C. T. Darimont, M. H. H. Price, N. N. Winchester, J. Gordon-Walker, P. C. Paquet

Biogeography and Ecological Opportunity Collection

Aim Predator–prey dynamics in fragmented areas may be influenced by spatial features of the landscape. Although little is known about these processes, an increasingly fragmented planet underscores the urgency to predict its consequences. Accordingly, our aim was to examine foraging behaviour of an apex mammalian predator, the wolf (Canis lupus), in an archipelago environment.

Location Mainland and adjacent archipelago of British Columbia, Canada; a largely pristine and naturally fragmented landscape with islands of variable size and isolation.

Methods We sampled 30 mainland watersheds and 29 islands for wolf faeces in summers 2000 and 2001 and identified prey remains. We examined …

National Program Assessment, Animal Health: 2000-2004, Cyril G. Gay

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

National Program Assessments are conducted every five-years through the organization of one or more workshop. Workshops allow the Agricultural Research Service (ARS) to periodically update the vision and rationale of each National Program and assess the relevancy, effectiveness, and responsiveness of ARS research. The National Program Staff (NPS) at ARS organizes National Program Workshops to facilitate the review and simultaneously provide an opportunity for customers, stakeholders, and partners to assess the progress made through the National Program and provide input for future modifications to the National Program or the National Program’s research agenda. A workshop for Animal Health has been …

Evolution Of Nociception In Vertebrates: Comparative Analysis Of Lower Vertebrates, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Nociception is an important sensory system of major fundamental and clinical relevance. The nociceptive system of higher vertebrates is well studied with a wealth of information about nociceptor properties, involvement of the central nervous system and the in vivo responses to a noxious experience are already characterised. However, relatively little is known about nociception in lower vertebrates and this review brings together a variety of studies to understand how this information can inform the evolution of nociception in vertebrates. It has been demonstrated that teleost fish possess nociceptors innervated by the trigeminal nerve and that these are physiologically similar to …

Wild Justice And Fair Play: Cooperation, Forgiveness, And Morality In Animals, Marc Bekoff

Ethology Collection

In this paper I argue that we can learn much about ‘wild justice’ and the evolutionary origins of social morality – behaving fairly – by studying social play behavior in group-living animals, and that interdisciplinary cooperation will help immensely. In our efforts to learn more about the evolution of morality we need to broaden our comparative research to include animals other than non-human primates. If one is a good Darwinian, it is premature to claim that only humans can be empathic and moral beings. By asking the question ‘What is it like to be another animal?’ we can discover rules …

Neuroanatomical Structure Of The Spinner Dolphin (Stenella Longirostris Orientalis) Brain From Magnetic Resonance Images, Lori Marino, Keith Sudheimer, William A. Mclellan, John I. Johnson

Veterinary Science and Medicine Collection

High-resolution magnetic resonance (MR) images of the brain of an adult spinner dolphin (Stenella longirostris orientalis) were acquired in the coronal plane at 55 antero-posterior levels. From these scans a computergenerated set of resectioned virtual images in the two remaining orthogonal planes was constructed with the use of the VoxelView and VoxelMath (Vital Images, Inc.) programs. Neuroanatomical structures were labeled in all three planes, providing the first labeled anatomical description of the spinner dolphin brain.

On Cary Wolfe's Animal Rites And Zoontologies, Matthew Wolf-Meyer

Reconstruction: Studies in Contemporary Culture

[First paragraph]

The question of the category of the animal and its relation to that of the human is one that has recently surfaced in the work of such theorists as Jacques Derrida, Donna Haraway and Giorgio Agamben; this recent concern with the speciesism that underlies scientific categorization, and the faulty structure such speciesism lends for philosophical investigations into the qualities of Man, has largely been framed within the context of humanism and the problematic of articulating posthumanist ethics. Reductively, the concerns of the above authors are the ways in which the difference that has been constructed between the human …

An Interim Report Of A Viking-Age & Medieval Archaeofauna From Undir Junkarinsfløtti, Sandoy, Faroe Islands, Thomas H. Mcgovern, Colin Amundsen, Sophia Perdikaris, Ramona Harrison, Yekaterina Krivogorskaya

School of Global Integrative Studies: Faculty Publications

Cooperative international excavations at the site of Undir Junkarinsfløtti (27020) in the village of Sandur on the island of Sandoy, Faroe Islands in May 2003 recovered a stratified bone - rich midden deposit extending from the Viking Age to the early medieval period. The animal bone collection contains domestic mammals (cattle, sheep, dog, goat, and pig) and substantial amounts of fish (mainly cod), birds (mainly puffin and guillemot), and shellfish (mainly limpet). While the current collection has the archaeological limitations inherent in column samples, it suggests persistence of substantial pig keeping into the 13th c, and strongly indicates a sustainable …

An Evaluation Of The Us High Production Volume (Hpv) Chemical-Testing Programme: A Study In (Ir)Relevance, Redundancy And Retro Thinking, Andrew Nicholson, Jessica Sandler, Troy Seidle

Experimentation Collection

Under the US Environmental Protection Agency (EPA) High Production Volume (HPV) Challenge Programme, chemical companies have volunteered to conduct screening-level toxicity tests on approximately 2800 widely-used industrial chemicals. Participating companies are committed to providing available toxicity information to the EPA and presenting testing proposals for review by the EPA and posting on the EPA Web site as public information. People for the Ethical Treatment of Animals (PETA) and a coalition of animal protection organisations have reviewed all the test plans submitted by the participating chemical companies for compliance with the original HPV framework, as well as with animal welfare guidelines …

Animal Model Research: The Apples And Oranges Quandary, Kenneth J. Shapiro

Experimentation Collection

In this paper, I explore the premises underlying the problem of the evaluation of animal models. I argue that the presence of similarities and differences between the model and the modelled, although historically and currently a dominant antinomy framing evaluation, is not a bottom-line consideration. What is critical is 1) whether we learn and 2) whether we improve treatment through the animal model research. Similarity between model and modelled and the closely related concept of validity are not coterminus with these critical evaluative measures. In fact, differences between the model and modelled also can provide impetus to new understanding and …

Free-Stall Dimensions: Effects On Preference And Stall Usage, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

In 2 experiments, free-stall dimensions were examined to determine how they affected stall preference, usage, cleanliness, and milk production in Holstein dairy cattle. In experiment 1, stall width (112 or 132 cm) and stall length (229 and 274 cm from curb to wall) were compared in a 2 × 2 factorial arrangement of stall treatments using 15 individually housed, non-lactating animals. Cows showed no clear preference for stall size as measured by lying time. When animals had no choice between stalls, average lying time was higher in the wide stalls than in the narrow stalls (10.8 vs. 9.6 ± 0.3 …

A 15th C. Archaeofauna From Akurvík, An Early Fishing Station In Nw Iceland, Colin Amundsen, Sophia Perdikaris, Matthew Brown, Yekaterina Krivogorskaya, Salena Modugno, Konrad Smiarowski, Shaye Storm, Malgorzata Frik, Monica Koczela, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

This is a report of analysis of 15th c bone materials from the site of Akurvík in NW Iceland excavated in 1990. A small international project in Árneshreppur district recovered a series of stratified midden deposits associated with small turf structures on an eroding beachfront. Radiocarbon dates identify at least two major phases of occupation and use, one extending into the mid 13th century, and the other dating to the mid 15th century. This report documents the animal bone collection from the later 15th c occupation. Dominated by cod fish, these deposits appear to be the product of seasonal fishery …

Reflections On Animal Selves, Marc Bekoff, Paul W. Sherman

Sentience Collection

Is self-cognizance a uniquely human attribute, or do other animals also have a sense of self? Although there is considerable interest in this question, answers remain elusive. Progress has been stymied by misunderstandings in terminology, a focus on a narrow range of species, and controversies over key concepts, experimental paradigms and interpretations of data. Here, we propose a new conceptual and terminological framework, emphasizing that degrees of self-cognizance differ among animals because of the cognitive demands that their species-specific social structures and life-history characteristics have placed upon them over evolutionary time. We suggest that the self-cognizance of an organism falls …

Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury

Aquaculture Collection

Dominance hierarchies of the three-spined stickleback Gasterosteus aculeatus from river and pond populations were subjected to hypoxia (20%, range±1%). Under hypoxia, the hierarchies were less stable in terms of rank position and tissue L-lactate was higher in river fish than pond fish under normoxia and hypoxia. Dominant fish gained mass under normoxia but lost mass under hypoxic conditions possibly due to them maintaining high levels of aggression.

A Critical Assessment Of Protection For Key Wildlife And Salmon Habitats Under The Proposed British Columbia Central Coast Land And Resource Management Plan, Paul C. Paquet, Chris T. Darimont, R. John Nelson, Katrina Bennett

Habitat Assessment and Management Collection

The Central Coast Land and Resource Management Plan (CCLRMP) table recently declared a consensus1 on proposed protected areas for British Columbia’s Central Coast. This region is recognized for its globally rare and largely intact mainland and island ecosystems and land use decisions should reflect this importance. We evaluated the efficacy of this proposal using a spatial assessment of habitat. We focus on protected areas in the context of the overall CCLRMP. We examined the level of protection provided by the CCLRMP in three key coastal habitats: deer winter range, wolf reproductive habitat, and salmon reproductive and rearing habitat. Assessment of …

A Model Of Animal Selfhood: Expanding Interactionist Possibilities, Leslie Irvine

Human and Animal Bonding Collection

Interaction between people and companion animals provides the basis for a model of the self that does not depend on spoken language. Drawing on ethnographic research in an animal shelter as well as interviews and autoethnography, this article argues that interaction between people and animals contributes to human selfhood. In order for animals to contribute to selfhood in the ways that they do, they must be subjective others and not just the objects of anthropomorphic projection. Several dimensions of subjectivity appear among dogs and cats, constituting a “core” self consisting of agency, coherence, affectivity, and history. Conceptualizing selfhood in this …

Levels Of Citation Of Nonhuman Animal Studies Conducted At A Canadian Research Hospital, Anne Innis Dagg, Troy K. Seidle

Experimentation Collection

The publication of scientific articles that receive few or no citations raises questions of the appropriate use of resources as well as ethics. In the case of animal research, the ethics issue extends beyond human patients to nonhuman animals, as the research subjects them to pain and, typically, to death. This study is a citation analysis of animal research conducted at Toronto's Hospital for Sick Children (HSC). Of the 594 publications (1990 to 1995) on animal research by affiliates of HSC, 29% received Iower than 10 citations in a 10-year period. We compare the research history of 13 "best" and …

Carl Cohen’S ‘Kind’ Arguments For Animal Rights And Against Human Rights, Nathan Nobis

Animal Welfare Collection

Carl Cohen’s arguments against animal rights are shown to be unsound. His strategy entails that animals have rights, that humans do not, the negations of those conclusions, and other false and inconsistent implications. His main premise seems to imply that one can fail all tests and assignments in a class and yet easily pass if one’s peers are passing and that one can become a convicted criminal merely by setting foot in a prison. However, since his moral principles imply that nearly all exploitive uses of animals are wrong anyway, foes of animal rights are advised to seek philosophical consolations …

Rehabilitating Rescued Chinese Farm Bears (Ursus Thibetanus): Results, Limitations, And Implications, Peter J. Li

Bear Farming Collection

The objects of daily physical abuse and appalling deprivation for up to 22 years, rescued Chinese farm bears (Ursus thibetanus) pose a comprehensive challenge to the Chengdu Asiatic Black Bear Rescue Center, created and managed by the Animals Asia Foundation. This study looks at the unique conditions of the rescued bears, examines the center’s rehabilitation program, and identifies the program’s limitations. Despite the world-class care provided by the center and the qualitative improvement in their health, the bears have irreparable physical and mental incapacitation that undercuts their chances to survive in the wild. This situation questions the moral ground of …

Protecting All Animals: A Fifty-Year History Of The Humane Society Of The United States, Bernard Unti

eBooks

In 1954, when The Humane Society of the United States was founded by a small handful of dedicated visionaries, the modern concept of "animal welfare" barely existed. Fifty years later, The HSUS is the nation's largest animal protection organization, with a constituency of more than 8 million people, and a leader in the parallel rise of the modern animal welfare movement. Protecting All Animals: A Fifty-Year History of The Humane Society of the United States is more than a chronicle of one organization; it is the saga of the journey toward a truly humane society.

Trials, Tribulations, And Trends In Tumor Modeling In Mice, Joann C. L. Schuh

Toxicology and Animal Models in Research Collection

Selection of mouse models of cancer is often based simply on availability of a mouse strain and a known compatible tumor. Frequently this results in use of tumor models long on history but short on homology and quality control. Other factors including genetics, sex, immunological status, method and site of tumor implantation, technical competence, biological activity of the tumor, protocol sequence and timing, and selection of endpoints interact to produce outcomes in tumor models. Common reliance on survival and tumor burden data in a single mouse model often skews expectations towards high remission and cure rates; a finding seldom duplicated …

Animal Bones From Sondum (27012) Sandoy, Faroe Islands 200 Season Collection, Thomas H. Mcgovern, Seth Brewington, Sophia Perdikaris, Colin Amundsen

School of Global Integrative Studies: Faculty Publications

Introduction

This paper reports on analysis of animal bones collect in 2000 by the Faroese Museum from a stratified but eroding beach front cliff in on the island of Sandoy. The site designation is Sondum, 27012 and the bone materials have been kindly sent to the CUNY laboratories for analysis by the excavator Simun Arge. While conditions of bone preservation are not as good as at the Undir Junkarinsfløtti locality to the SW across the embayment, and sample size is much smaller, a substantial amount of bone was recovered from datable which adds to our understanding of early economic patterns …

Coping With Hard Times In Nw Iceland: Zooarchaeology, History, And Landscape Archaeology At Finnbogastaðir In The 18th Century, Ragnar Edvarsson, Sophia Perdikaris, Thomas H. Mcgovern, Noah Zagor

School of Global Integrative Studies: Faculty Publications

During a cooperative archaeological project in NW Iceland (Strandasýsla) involving the Icelandic National Museum and Hunter College of the City University of New York.1990 season, a small rescue excavation at the site of Finnbogastaðir generated a quantifiable collection of animal bones dating to the early modern period, mainly to the 18th century. The 18th c was a period of hardship in much of Iceland, with widespread tenantry, adverse climate, and degradation of many terrestrial landscapes posing severe challenges to poor farmers- perhaps most intensely in the Vestfirðir. The animal bone collection from Finnbogastaðir reflects a multi-stranded subsistence economy involving seals, …

Effect Of Pig Weaning Age And Commingling After The Nursery Phase On Humoral And Behavioral Indicators Of Well-Being And On Growth Performance, Sarah C. Arthur, Mari E. Davis, Jason K. Apple, Charles V. Maxwell

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

Two hundred and sixteen pigs were weaned at 14 or 21 d of age to determine the effect of weaning age and commingling after the nursery phase on growth and behavior of pigs in a wean-to-finish facility. Pigs were divided into older and younger age groups and allotted 12 pigs/pen with nine replications of each group. At the end of the nursery phase (d 34 after weaning), one-half of the pigs in each group were removed and commingled for the grower/finisher phase and the other half remained in their original pens. Beginning at weaning (d 0), pigs were monitored via …

Impact Of Dietary Changes On Hepatic Homocysteine Metabolism In Young Broilers, Fauna M. Ganson, Padmakumar Pillai, Jason L. Emmert

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

Information regarding the impact of sulfur amino acids (SAA) on hepatic homocysteine (Hcy) flux through the various metabolic pathways competing for Hcy in young broilers is lacking. An experiment was conducted to evaluate the impact of varying levels of dietary methionine (Met), choline, and betaine on hepatic Hcy flux in young broiler chickens. A standard starter basal diet was fed to chicks until 8 d of age; 12 experimental diets were given from 8-22 d. The experimental basal diet contained deficient levels of Met and cysteine (Cys); supplemental Met (0, 0.08, 0.16, and 0.24%) was added to the basal diet …

Laboratory-Scale Evaluation Of Incandescent And Compact Florescent Lamps For Poultry House Lighting, Leanne Gabriel, Donald M. Johnson

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

This laboratory-scale study compared 1000- and 2000-h rated 60W incandescent lamps and 6000-h rated 60W-equivalent compact florescent lamps over 6000 h of simulated broiler-house operation. The four original 1000-h incandescent lamps were replaced 22 times and the four 2000-h incandescent lamps were replaced 14 times. None of the four compact florescent lamps failed during the 6000-h experiment, although one was broken due to human error. Both types of incandescent lamps had significantly higher (p < .0001) mean illuminance (lx) than did the compact florescent lamps. The compact florescent lamps used significantly less (p < .0001) power (W) and had significantly higher (p < .0001) efficiency (lx/W) than the incandescent lamps. Despite a higher initial purchase price, the total cost (purchase + replacement + electrical) of operating compact florescent lamps was approximately 36% lower than the total cost of operating either type of incandescent lamp over the 6000 h period. The results of this study indicate that even at a least-cost price for electricity ($0.04/kW/h), growers can reduce total broiler-house lighting costs by replacing incandescent lamps with compact florescent lamps.

Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe

Journal of the Arkansas Academy of Science

As thermal infrared imaging technology has improved, it has increasingly been used for estimating sizes of wildlife populations. The greatest bias of thermal infrared surveys is the lack of known detection rates to adjust for visibility bias. As with visual surveys, a measure of detection rate is needed to provide unbiased estimates. We assessed the detection rate of white-tailed deer (Odocoileus virginianus) using a thermal infrared sensor (1.2 - 5.9 /an) from an aerial platform. Similar characteristics between thermal signatures of people and deer allowed us to use people in a reclined or horizontal position as surrogates for deer. We …
