Underwater Noise Level Recordings from a Water Intake Pontoon and Possible Impacts on Yangtze Finless Porpoises in a Natural Reserve
| Contributor(s):: Lu, Wenfei, Tong, Jianfeng, Zhang, Xianfeng, Zhu, Bin, Dong, Weiwei
Underwater noise pollution caused by human activities may affect freshwater cetaceans to different degrees. To analyze the impacts of water intake pontoons on Yangtze finless porpoises (Neophocaena asiaeorientalis), this study collected underwater noise data from such a pontoon in a nature...

The Impact of Acute Loud Noise on the Behavior of Laboratory Birds
| Contributor(s):: Tayanne L. Corbani, Jessica E. Martin, Susan D. Healy
Husbandry procedures and facility settings, such as low-frequency fire alarms, can produce noises in a laboratory environment that cause stress to animals used in research. However, most of the data demonstrating harmful effects that have, consequently, led to adaptations to management, have...

Potential Impact of Construction Noise on Selected Zoo Animals
| Contributor(s):: Richard Jakob-Hoff, Michael Kingan, Chiaki Fenemore, Gian Schmid, John F. Cockrem, Amanda Crackle, Emily Van Bemmel, Rebecca Connor, Kris Descovich
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...

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...

Role of noise and music as anxiety modulators: Relationship with ovarian hormones in the rat
| Contributor(s):: Escribano, Begoña, Quero, Ismael, Feijóo, Montserrat, Tasset, Inmaculada, Montilla, Pedro, Túnez, Isaac
This work aims to verify the role of noise and music as anxiety modulators and their relationship with ovarian hormones. For this purpose, female Wistar rats were used and treated, forming different experimental groups, with 17-β-estradiol, progesterone, allopregnanolone, finasteride (inhibitor...

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...

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...

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

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...
