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...

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...

Visitor effects on zoo-housed Sulawesi crested macaque (Macaca nigra) behaviour: Can signs with ‘watching eyes’ requesting quietness help?
Contributor(s):: Dancer, Alice M. M., Burn, Charlotte C.
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...

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...

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...

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...

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...

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...

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...
