  1. The Effect of Extensive Human Presence at an Early Age on Stress Responses and Reactivity of Juvenile Ostriches towards Humans

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

    The effect of extensive human presence and regular gentle handling performed at an early age (0–3 months old) on stress responses and reactivity of juvenile ostriches towards humans was investigated. A total of 416 ostrich chicks over two years were exposed to one of three treatments for...

    Resumo: A manutenção de cães comunitários surge como uma alternativa compassiva de manejo que contribui para o controle populacional e para a melhoria de vida dos cães, colaborando para diminuição de riscos para a saúde humana. É...

  3. You Are Not My Handler! Impact of Changing Handlers on Dogs' Behaviours and Detection Performance

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

    Dog-handler relationships can directly impact team success. Changing a dog’s handler may therefore compromise detection performance. However, there are currently few studies which support this. This research explored the performance and behavioural impact of changing a dog’s...

  4. Effects of Rider Experience Level on Horse Kinematics and Behavior

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

    Large riding lesson programs are an essential part of the horse industry. To meet demand and remain profitable, lesson barns sometimes require horses to work multiple times a day with different rider levels. There is little guidance as to the behavioral and physical effects of such protocols,...

  5. Programas de socialização para cachorros: uma só saúde

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

    A medicina comportamental de animais de companhia tem vindo a sofrer uma enorme evolução ao longo dos últimos anos, nomeadamente no que concerne o desenvolvimento comportamental do cachorro e os seus programas de socialização. Paralelamente, também a...

  6. The Need for a Convergence of Agricultural/Laboratory and Zoo-based Approaches to Animal Welfare

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

    Advances in animal welfare science have led to a high number of studies published for farm, laboratory and zoo animals, with a huge breadth of innovative topic areas and methodologies. This paper investigates the different approaches used to undertake welfare research in farm, laboratory and zoo...

  7. Global mapping of landscape fragmentation, human-animal interactions, and livelihood behaviors to prevent the next pandemic

  8. Behavioral and Perceptual Differences between Sexes in Dogs: An Overview

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

    In this paper, we review the scientific reports of sex-related differences in dogs as compared to the outcomes described for wild animals. Our aim was to explore whether the differences in male and female dogs were affected by the domestication process, in which artificial selection is the main...

  9. Human development and climate affect hibernation in a large carnivore with implications for human–carnivore conflicts

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

    1. Expanding human development and climate change are dramatically altering habitat conditions for wildlife. While the initial response of wildlife to changing environmental conditions is typically a shift in behavior, little is known about the effects of these stressors on hibernation...

  10. Effect of a Standardized Four-Week Desensitization and Counter-Conditioning Training Program on Pre-Existing Veterinary Fear in Companion Dogs

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

    Many dogs show signs of fear during veterinary appointments. It is widely recommended to use desensitization and counter-conditioning training to reduce this fear. However, the efficacy of this method for reducing veterinary fear has not been examined. We assessed the effect of a standardized...

  11. Zoo visitor effect on mammal behaviour: Does noise matter?

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

    The zoo visitor effect is the change in animal behaviour and physiology in response to the presence of a viewing public. It is thought to result from, amongst other things, visitor generated sound (i.e., noise), but this hypothesis has never been explicitly tested. We tested this hypothesis...

  12. Measuring fear in dogs by questionnaires: An exploratory study toward a standardized inventory

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

    Several types of questionnaires are in use to measure fear-related behaviour in family dogs. Our aim was to develop a general questionnaire based on relevant previous studies in order to facilitate the standardization of measurements of fear-related behaviour in dogs (social fear, non-social...

  13. Lack of mirror use by pigs to locate food

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

    Many mammalian species, as well as birds, are able to use a mirror either in the context of self-recognition, or instrumentally for discovering and manipulating objects that cannot be perceived directly. A noteworthy study by Broom et al. (2009) investigated the ability of pigs (Sus scrofa) to...

  14. Fear responses to noises in domestic dogs: Prevalence, risk factors and co-occurrence with other fear related behaviour

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

    Behavioural signs of fear or anxiety on exposure to noises in owned domestic dogs have been suggested in clinical studies to be common and a significant welfare concern. In this study two approaches were taken to investigate the occurrence of, and risk factors for, these behaviours: a postal...

  15. Extensive human presence at an early age of ostriches improves the docility of birds at a later stage of life

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

    While ostriches are relatively wild birds with a short period of domestication, some birds demonstrate a strong interest in humans. Human imprinting of chicks could therefore facilitate the cooperation of birds for assisted reproduction technology purposes, improving the quality of human–bird...

  16. Automatic registration of grazing behaviour in dairy cows using 3D activity loggers

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

    Automated systems for monitoring behaviour of cows within dairy production are increasing and developments in technology provide new opportunities in this area. This study aimed to validate the use of a 3D activity logger (HOBO® Pendant G Data Logger), that registers the cow's head positions...

  17. Animal handling and stress-related behaviour at mobile slaughter of cattle

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

    By avoiding animal transportation, mobile slaughter may have the potential to reduce animal stress. In a cross-sectional study with elements of cohort design, we investigated relationships between animal handling and stress-related animal behaviours in connection with slaughter at two Swedish...

  20. Visitor effects on zoo-housed Sulawesi crested macaque (Macaca nigra) behaviour: Can signs with ‘watching eyes’ requesting quietness help?

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

    Visiting public can cause changes in the behaviour of zoo-housed primates. These effects, if indicative of stress, can be of welfare concern. However, few options to mitigate visitor effects through modulating visitor behaviour have been explored. Here we evaluated the effects of visitor number...
