A note on enrichment for spontaneous tool use by chimpanzees ( Pan troglodytes )
Contributor(s):: Morimura, N.
In the wild, decisions as to "when", "where", and "how" an animal acts are made based on the individual's own choice; in contrast, the behaviour of wild animals in captivity may be under human control. To improve the physical and psychological well-being of captive animals, we should ensure that...
ISAE international congresses, 1999-2001. (International Society for Applied Ethology Special Issue)
Contributor(s):: Widowski, T., Mench, J.
This special issue of Applied Animal Behaviour Science contains topics on the International Society for Applied Ethology (ISAE) congress. The 8 topics include (1) human-animal interactions in livestock production; (2) applied and basic research in farm animal welfare; (3) transferring the results...
A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups
Contributor(s):: Schapiro, S. J., Nehete, P. N., Perlman, J. E., Sastry, K. J.
A variety of psychosocial factors have been shown to influence immunological responses in laboratory primates. The present investigation examined the effects of social housing condition on cell-mediated immune responses, comparing rhesus macaques (Macaca mulatta) in three housing conditions...
Indication of a genetic basis of stereotypies in laboratory-bred bank voles ( Clethrionomys glareolus )
Contributor(s):: Schoenecker, B., Heller, K. E.
The development of stereotypies was studied in 2 successive laboratory-bred generations of bank voles representing F1 (n=248) and F2 (n=270) of an originally wild caught stock. It was shown that the propensity to develop stereotypies under barren housing conditions strongly relates to the same...
Guidelines for the ethical use of animals in applied ethology studies. (International Society for Applied Ethology Special Issue)
Contributor(s):: Sherwin, C. M., Christiansen, S. B., Duncan, I. J., Erhard, H. W., Lay, D. C., Jr., Mench, J. A., O'Connor, C. E., Petherick, J. C.
Applied ethology has a continuing interest in the promotion of animal welfare and the ethical treatment of animals used in research. However, in contrast to some other fields involving animal research, there are currently no guidelines written specifically for those engaged in applied ethology...
The effect of the functional attributes of objects within the caged environment on interaction time in laboratory rats
Contributor(s):: Williams, C. M., Hanmer, L. A., Riddell, P. M.
Determining rat preferences for, and behaviour towards, environmental enrichment objects allows us to provide evidence-based information about how the caged environment may be enriched. In recent years there have been many studies investigating the preferences of laboratory rodents for a wide...
Short-term social memory in the laboratory rat: its susceptibility to disturbance
Contributor(s):: Burman, O. H. P., Mendl, M.
Adult rats presented with a juvenile conspecific for 5 min on 2 occasions, separated by a 15-min inter-exposure interval (IEI), investigated the reintroduced juvenile significantly less in the second encounter. It is suggested that this was because the adult rats remembered the identity of the...
Effects of cage-cleaning frequency on laboratory rat reproduction, cannibalism, and welfare
Contributor(s):: Burn, C. C., Mason, G. J.
Regular cage-cleaning is important for health, but for breeding rats it disrupts the nest and removes olfactory signals important for parental care. To investigate how different cage-cleaning frequencies affect breeding rats' health and welfare, we monitored reproductive output, pup mortality,...
A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages
Contributor(s):: Chu, L. R., Garner, J. P., Mench, J. A.
Despite their gregarious nature, rabbits used for research are often housed individually due to concerns about aggression and disease transmission. However, conventional laboratory cages restrict movement, and rabbits housed singly in these cages often perform abnormal behaviours, an indication...
Effects of a running wheel-igloo enrichment on aggression, hierarchy linearity, and stereotypy in group-housed male CD-1 (ICR) mice
Contributor(s):: Howerton, C. L., Garner, J. P., Mench, J. A.
Environmental enrichment is an important strategy to improve the welfare of laboratory animals. Running wheels might serve as enrichment devices for laboratory mice, since mice use them extensively when they are provided. However, competition among group-housed mice for such highly preferred...
Ethical issues faced by field primatologists: asking the relevant questions. (Special Issue: Ethical Issues in field primatology.)
Contributor(s):: Fedigan, L. M.
Field primatologists face unusual ethical issues. We study animals rather than people and receive research approval from animal care rather than ethics committees. However, animal care evaluation forms are developed from concerns about laboratory animal research and are based on the "Three R's"...
