  1. Dogs fail to reciprocate the receipt of food from a human in a food-giving task

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    Domestic dogs have been shown to reciprocate help received from conspecifics in food-giving tasks. However, it is not yet known whether dogs also reciprocate help received from humans. Here, we investigated whether dogs reciprocate the receipt of food from humans. In an experience phase,...

    Journal Articles

    Domestic dogs have been shown to reciprocate help received from conspecifics in food-giving tasks. However, it is not yet known whether dogs also reciprocate help received from humans. Here, we investigated whether dogs reciprocate the receipt of food from humans. In an experience phase,...

  3. Potential Impact of Construction Noise on Selected Zoo Animals

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    In anticipation of a major construction project in an urban New Zealand zoo, a study was initiated to assess the response to construction noise of selected animal species (elephant, giraffe, emu and alligator) previously observed to be sensitive to this kind of noise. The overall aim was to...

  4. Non-invasive Assessment of Fecal Stress Biomarkers in Hunting Dogs During Exercise and at Rest

    Journal Articles

    Intense exercise causes to organisms to have oxidative stress and inflammation at the gastrointestinal (GI) level. The reduction in intestinal blood flow and the exercise-linked thermal damage to the intestinal mucosa can cause intestinal barrier disruption, followed by an inflammatory...

  5. The Use of Environmental Enrichments Affects Performance and Behavior of Growing Rabbits Housed in Collective Pens

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    This study assessed the effects of an elevated plastic-slatted platform and/or a plastic hiding tube in collective pens with large group sizes (27 or 36 rabbits/pen; 16 rabbits/m2) on the performance and welfare of rabbits kept from weaning (at 33 days of age) to slaughter (at 68 or 75 days of...

  6. Eye Blink Rates and Eyelid Twitches as a Non-Invasive Measure of Stress in the Domestic Horse

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    Physiological changes provide indices of stress responses, however, behavioural measures may be easier to determine. Spontaneous eye blink rate has potential as a non-invasive indicator of stress. Eyelid movements, along with heart rate (HR) and behaviour, from 33 horses were evaluated over...

  7. Effects of Visitors and Enrichments on Behavior of Captive Red Wolves' (Canis rufus) at the Great Plains Zoo, Sioux Falls, South Dakota

    Theses | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    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...

  8. How do primary pre-service teachers assess circus with animals and its educational value? A study with Portuguese, Spanish and Greek students

    Conference Papers

    This study aimed to check the opinion of primary pre-service teachers about circus with animals, including if they recognize any educational value in this type of show and how they assess the animals’ treatment in this place. For that, a questionnaire with open and closed questions was...

  9. Does the provision of environmental enrichment affect the behaviour and welfare of captive snakes?

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

  10. Evaluation of Animal-Based Indicators to Be Used in a Welfare Assessment Protocol for Sheep

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    Sheep are managed under a variety of different environments (continually outdoors, partially outdoors with seasonal or diurnal variation, continuously indoors) and for different purposes, which makes assessing welfare challenging. This diversity means that resource-based indicators are not...

  11. Equine Activities Influence Horses' Responses to Different Stimuli: Could This Have an Impact on Equine Welfare?

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    The learning and cognitive challenges that horses may face differ according to the activities in which they are involved. The aim of this investigation was to study the influence of equine activities on the behavioral responses and autonomic nervous system (ANS) activity of adult horses....

  12. The Social Rank of Zoo-Housed Japanese Macaques is a Predictor of Visitor-Directed Aggression

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    The effect that visitors have on the behavior and welfare of animals is a widely-studied topic in zoo animal welfare. Typically, these studies focus on how the presence or activity levels of visitors affect animals. However, for many species, and particularly primates, social factors, such as...

  13. Voluntary Rein Tension in Horses When Moving Unridden in a Dressage Frame Compared with Ridden Tests of the Same Horses—A Pilot Study

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    Too much rein tension while riding may compromise the welfare of the horse. But who generates the tension on the reins—the horse or the rider? The primary aim of this pilot study was to evaluate the maximum rein tension that horses voluntarily maintain without a rider compared to rein...

  14. Evaluating the Behavior and Temperament of African Penguins in a Non-Contact Animal Encounter Program

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    Animal ambassador programs are increasingly prevalent in zoos, yet few studies have investigated their impact on animal welfare. We assessed the effects of an ambassador program on the behavior of a colony (N = 15) of zoo-housed African penguins (Spheniscus demersus) and evaluated whether...

  15. Feeding Enrichment in a Captive Pack of European Wolves (Canis Lupus Lupus): Assessing the Effects on Welfare and on a Zoo's Recreational, Educational and Conservational Role

    Journal Articles | Contributor(s): Alison E. Ries, Catherine Marrs Fuchsel (adviser)

    This study investigated the effects of two feeding enrichment programs on the behaviour of a captive pack of European wolves (Canis lupus lupus) and their correlation with both zoo visitors’ interest towards the exhibit and their overall perception of the species. Behavioural data...

  16. More Than "Just" Walking: An Observational Study of Dog-Related Physical Activities

    Journal Articles

    Dog ownership has been shown to correlate with physical activity (PA). However, knowledge about the intensities of dog-related PA (drPA) is still lacking. To investigate the duration and intensity of drPA in consideration of PA guidelines, an observational study of dog owners (DO) was...
