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

    Contributor(s):: Quadros, Sandra, Goulart, Vinicius D. L., Passos, Luiza, Vecci, Marco A. M., Young, Robert J.

    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...

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

    Contributor(s):: Temesi, Andrea, Turcsán, Borbála, Miklósi, Ádám

    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...

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

    Contributor(s):: Blackwell, Emily J., Bradshaw, John W. S., Casey, Rachel A.

    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...

  4. Attention, noise, and implications for wildlife conservation and management

    Contributor(s):: Chan, Alvin Aaden Yim-Hol, Blumstein, Daniel T.

    Anthropogenic stimuli are often viewed as disturbances that directly interfere with signal processing or communication, or directly harm animals. However, such sounds may also distract individuals and thus potentially interfere with their ability to make biologically important decisions about...

  5. Low welfare impact of noise: assessment in an experimental model of mice infected by Herpes simplex-1

    Contributor(s):: Trindade Madeira Araújo, Fernanda, Espírito Santo, Lilia de Cássia, Peixoto Teixeira, Ana Carolina, Senra Santos, Beatriz, Galvão Filho, Bruno, Souza Silva, Thais, Duarte, Marina Henriques Lage, da Silva Vasconcellos, Angélica, Farias de Alvarenga, Kevin Augusto, Viana Magno, Luiz Alexandre, Cavalcante, Krisdany Vinícius, Young, Robert John, Campos, Marco Antônio

    The breeding practices adopted and the equipment typically found in animal facilities produce sounds at frequencies within the auditory range of the mice (1 to 100 kHz), which can cause hearing and other non-hearing effects. Another aspect that could potentially affects the welfare of...

  6. The effects of mining machinery noise of different frequencies on the behaviour, faecal corticosterone and tissue morphology of wild mice (Mus musculus)

    Contributor(s):: Mancera, Karen F., Lisle, Allan, Allavena, Rachel, Phillips, Clive J. C.

    Mining noise has a wide variety of frequency spectra and is a potential source of stress for wildlife. We evaluated the effects of mining machinery noise on behaviour and associated physiological parameters at two isoenergetic frequency ranges: high (>2kHz) and low (≤2kHz), the latter being less...

  7. The effect of a pressure vest on the behaviour, salivary cortisol and urine oxytocin of noise phobic dogs in a controlled test

    Contributor(s):: Pekkin, Anne-Maria, Hänninen, Laura, Tiira, Katriina, Koskela, Aija, Pöytäkangas, Merja, Lohi, Hannes, Valros, Anna

    Fear of loud noises is a common welfare problem in pet dogs. Commercial treatment vests have been tested on dogs to relieve noise phobia, and peripheral oxytocin has been suggested to be one of the stress-relieving mediators. The effect of vests has not, however, been tested in a controlled...

  8. Validation of modified open field behaviour as a measure of trait anxiety in the dog

    Contributor(s):: Wormald, Dennis, Lawrence, Andrew J., Carter, Gabrielle, Fisher, Andrew D.

    Trait anxiety may be a predisposing factor for anxiety-related behavioural problems in dogs. This study aimed to measure and quantify trait anxiety using novel behavioural paradigms. Diazepam is an anxiolytic drug which can be used to validate behavioural paradigms that are designed to measure...

  9. The effects of mining machinery noise of different amplitudes on the behaviour, faecal corticosterone and tissue morphology of wild mice (Mus musculus)

    Contributor(s):: Mancera, Karen F., Besson, Marie, Lisle, Allan, Allavena, Rachel, Phillips, Clive J. C.

    Mining noise has been identified as a source of stress for wildlife but the effects on the behaviour and physiology of individuals are largely unknown. We evaluated the effects of exposing wild mice to mining machinery noise for 3 weeks at two amplitude ranges: high (HA; 70-75 dB (A)) and low...

  10. Altered acoustic environments influence boldness in minnows

    Contributor(s):: Hasan, Md Robiul, Crane, Adam L., Poulin, Nicolas P., Ferrari, Maud C. O., Chivers, Douglas P.

    Human-induced noise has a pervasive influence on the behaviour of animals in their natural environment, but little scientific attention has gone toward noises that regularly affect animals being maintained in captivity for research purposes. Here, we assessed underwater aquarium noise produced...

  11. Separation, Confinement, or Noises: What Is Scaring That Dog?

    Contributor(s):: Ballantyne, K. C.

  12. The effect of zoo visitors on the behaviour and welfare of zoo mammals

    Contributor(s):: Alexandra Farrand

    There is evidence that the presence of the visiting public affects the behaviour of zoo-housed mammals. Understanding the effect of visitors is important in improving animal welfare, achieving zoo conservation goals, increasing visitor education/entertainment, and facilitating interpretation of...

  13. The Management of Horses during Fireworks in New Zealand

    Contributor(s):: Gabriella Gronqvist, Chris Rogers, Erica Gee

    Within popular press there has been much coverage of the negative effects associated with firework and horses. The effect of fireworks has been documented in companion animals, yet no studies have investigated the negative effects, or otherwise, of fireworks on horses. This study aims to document...

  14. Validation of HOBO Pendant data loggers for automated step detection in two age classes of male turkeys: growers and finishers

    Contributor(s):: Dalton, H. A., Wood, B. J., Dickey, J. P., Torrey, S.

    Activity levels can be used as a predictor of health status, physical condition, feed efficiency, and coping style in animals. Small, portable data loggers have been validated as an inexpensive and effective alternative to video or live observation for automated activity detection in several...

  15. Traits of drug and explosives detection in dogs of two breeds as evaluated by their handlers and trainers

    Contributor(s):: Adamkiewicz, E., Jezierski, T., Walczak, M., Gorecka-Bruzda, A., Sobczynska, M., Prokopczyk, M., Ensminger, J.

    Police dogs handlers' and trainers' opinions on Labrador retrievers (n=87) and German shepherds (n=96) trained for drugs vs. explosives detection have been compared. As most important traits in both specialties the responders indicated: (1) willingness to sniff objects, (2) concentration...

  16. Noise sensitivity in 17 dog breeds: prevalence, breed risk and correlation with fear in other situations

    Contributor(s):: Storengen, L. M., Lingaas, F.

    A web-based survey was conducted to estimate prevalence of noise sensitivity in 17 dog breeds in Norway ( n=5257). Major focus was on noise from fireworks, loud noises (bang/gunshots), thunderstorms and heavy traffic. The study also investigated risk factors as well as correlation with some other...

  17. Effects of sounds of different quality on the behaviour and heart beat parameters of goats

    Contributor(s):: Johns, J., Patt, A., Hillmann, E.

    In alpine regions, bells are used to relocate free-ranging grazers like cows and goats. Considering that goats have a well-developed hearing capacity, sounds (e.g. a chime of a bell) may act as stressors depending on their characteristics. The aim of this study was to test whether a non-uniform...

  18. The effects of human age, group composition, and behavior on the likelihood of being injured by attacking pumas

    Contributor(s):: Coss, R. G., Fitzhugh, L. E., Schmid-Holmes, S., Kenyon, M. W., Etling, K.

    Documentation from the years 1890 to 2000 of 185 instances of pumas (Puma concolor) attacking humans in the United States and Canada has provided statistical evidence that pumas are less likely to kill or injure humans in certain circumstances. We identified incidents of fatal attacks, severe...

  19. Vowel Discrimination in Cats: Acquisition, Effects of Stimulus Level, and Performance in Noise

    Contributor(s):: Hienz, Robert D., Aleszczyk, Cynthia M., May, Bradford J.

  20. A case study: the effect of visitors on two captive pumas with respect to the time of the day

    Contributor(s):: Maia, C. M., Volpato, G. L., Santos, E. F.

    This study analyzed the effects of noise levels and number of visitors on the behaviors of a mother puma and her daughter in a zoo environment with respect to the time of day. The study monitored visitation (noise and number) over two 1-week periods (4 weeks between periods) and frequency of...
