Fear responses to novelty in testing environments are related to day-to-day activity in the home environment in dairy cattle
Contributor(s):: MacKay, Jill R. D., Haskell, Marie J., Deag, John M., van Reenen, Kees
Behavioural tests for cattle take time to perform and can be stressful for the animals but are currently the only way of assessing behavioural reactions to fear-causing stimuli in a standardised manner. It may be possible to use behavioural data collected remotely in the home pen environment...
Establishing the extent of behavioural reactions in dairy cattle to a leg mounted activity monitor
Contributor(s):: MacKay, Jill R. D., Deag, John M., Haskell, Marie J.
Tri-axial accelerometers, typically used in activity monitors for detecting oestrus events in dairy cattle, are potentially a valuable device in the ethologist's toolbox. They open up the possibility of monitoring large numbers of animals over long periods of time with minimum human intervention....
African elephants ( Loxodonta africana) can detect TNT using olfaction: implications for biosensor application
Contributor(s):: Miller, A. K., Hensman, M. C., Hensman, S., Schultz, K., Reid, P., Shore, M., Brown, J., Furton, K. G., Lee, S.
The impact of war on local wildlife can be devastating, the effects of which are often felt well beyond the terminus of the initial threat. In areas where wildlife experiences unrestricted movement through previously affected zones, residual, unexploded landmines present a significant and...

Assessing acute effects of trapping, handling, and tagging on the behavior of wildlife using GPS telemetry: a case study of the common brushtail possum
Contributor(s):: Dennis, T. E., Shah, S. F.
Trapping, handling, and deployment of tracking devices (tagging) are essential aspects of many research and conservation studies of wildlife. However, often these activities place nonhuman animals under considerable physical or psychological distress, which disrupts normal patterns of behavior...
Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?
Contributor(s):: Burwell, A. K., Baldwin, A. L.
In animal facilities, noises, often poorly controlled, occur over a wide range of frequencies and intensities. Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology, but it is not known how they affect the autonomic nervous system (ANS). This study...
Possible costs of radio-tracking a young adult female mantled howler monkey ( Alouatta palliata ) in deciduous habitat of Costa Rican tropical dry forest
Contributor(s):: Hilpert, A. L., Jones, C. B.
Field experiments are required to determine the causes of the patterns identified in this report and their potential threats to the internal validity of field studies on mantled howlers. The literature on biotelemetry suggests that radio collars are likely to have deleterious effects on animals...

A note on silent ovulation identified by using radiotelemetry for estrous detection
Contributor(s):: Shipka, M. P.
The occurrence of silent ovulation in high-producing, postpartum Holstein cows was examined. 19 multiparous cows were fitted with transmitters (HeatwatchReg.) for radiotelemetry and examined using a visual oestrus detection routine for 1/2 h twice daily, on day 10 post partum. Blood samples were...
Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain
Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.
Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...
Consistency of individual behavioural characteristics of dairy cows in their home pen
Contributor(s):: Schrader, L.
The aim of this study was to identify reliable individual behavioural characteristics of dairy cows based on aspects of their spontaneous behaviour and their reactions towards behavioural tests performed in their home pen. The parameters measured were supposed to reflect how easily the behaviour...
Effects of environmental stressors on deep body temperature and activity levels in silver fox vixens ( Vulpes vulpes )
Contributor(s):: Bakken, M., Moe, R. O., Smith, A. J., Selle, G. M. E.
The present study was performed to investigate the effects of 14 different environmental stimuli on stress-induced hyperthermia (SIH) and levels of locomotor activity in 6 (3 infanticidal (killed their offspring during the previous year), 3 non-infanticidal) 2.5-year-old silver fox vixens. The...
Taking the time to assess the effects of remote sensing and tracking devices on animals
Contributor(s):: McMahon, C. R., Collier, N., Northfield, J. K., Glen, F.
The remote monitoring of animal behaviour using telemetry and bio-logging has become popular due to technological advances, falling costs of devices and the need to understand behaviour without causing disturbance to subjects. Over the past three decades thousands of animals have had their...
Reindeer and caribou ( Rangifer tarandus ) response towards human activities
Contributor(s):: Reimers, E., Colman, J. E.
We address the question of how human activities and infrastructure influence reindeer/caribou's (R. tarandus) behaviour and habitat use in Norway and review studies based on current methodologies. Anthropogenic activities have a direct affect on Rangifer behaviour through the senses hearing,...

ETHOSYS (R) - new system for recording and analysis of behaviour of free-ranging domestic animals and wildlife
Contributor(s):: Scheibe, K. M., Schleusner, T., Berger, A., Eichhorn, K., Langbein, J., Zotto, L. dal, Streich, W. J.
A storage telemetry system has been developed to monitor domestic animals and wildlife. It can be used for automatic recording of different patterns of behaviour, such as activity and feeding, and is based on advanced analysis of sensor-emitted signals. The system is made up of collars with...

A brief report on the relationship between level of milk production and estrous behavior of lactating dairy cows
Contributor(s):: Lopez, H., Satter, L. D., Wiltbank, M. C.
The objective of this study was to evaluate if there was an association between milk production and duration of estrus in lactating cows as determined by standing activity recorded by a radiotelemetry system. Holstein cows (n=42) were fitted with a radiotelemetric transmitter that allowed...
Identifying activity patterns from activity counters in ETHOSYSReg. collars on red deer
Contributor(s):: Pepin, D., Renaud, P. C., Decuq, F.
Identifying activity patterns of animals from activity counts recorded by sensors in the storage-telemetry-system ETHOSYSReg. requires to calibrate activity counters to field activities. We continuously observed from dawn to dusk during days 1, 3 and 5 three collared red deer hinds introduced...
Normal and more highly reactive horses. II. The effect of handling and reserpine on the cardiac response to stimuli
Contributor(s):: McCann, J. S., Heird, J. C., Bell, R. W., Lutherer, L. O.
A split-plot experiment evaluated the effect of handling and a tranquillizer, reserpine, on the autonomic heart-rate response of yearling horses to various stimuli. The emotionality levels of 32 Quarter-Horse yearlings were rated by 4 experienced horsemen on a scale from 1 to 4 (1 = most nervous...
