Pisula, W., Modlinska, K., Chrzanowska, A. 2019. Behavioural response to the environmental changes of various types in Lister-Hooded male rats. Scientific Reports 9, 7111.

The animal preference for complexity is most clearly demonstrated when the environmental change takes the form of an increase in complexity. Therefore, one of the potential difficulties in interpretation is that the preference for perceptual...

Fehlhaber, B., Heinemann, A. S., Rübensam, K. et al. 2019. A sensitive scoring system for the longitudinal clinical evaluation and prediction of lethal disease outcomes in newborn mice. Scientific Reports 9, 5919.

Neonatal animal models are increasingly employed in order to unravel age-specific disease mechanisms. Appropriate tools objectifying the clinical condition of murine neonates are lacking. In this study, we tested a scoring system specifically designed for...

Makowska, I. J., Franks, B., El-Hinn, C. et al. 2019. Standard laboratory housing for mice restricts their ability to segregate space into clean and dirty areas. Scientific Reports 9, 6179.

Laboratory mice (Mus musculus) are typically housed in simple cages consisting of one open space. These standard cages may thwart mouse ability to segregate resting areas from areas where they eliminate, a behaviour that is...

Chisholm, J., De Rantere D., Fernandez, N. J. et al. 2013. Carbon dioxide, but not isoflurane, elicits ultrasonic vocalizations in female rats. Laboratory Animals 47(4), 324-7.

Gradual filling of a chamber with carbon dioxide is currently listed by the Canadian Council on Animal Care guidelines as a conditionally acceptable method of euthanasia for rats. Behavioural evidence suggests, however, that exposure to...

Lidster, K., Jefferys, J. G., Blümcke, I. et al. 2016. Opportunities for improving animal welfare in rodent models of ep

Animal models of epilepsy and seizures, mostly involving mice and rats, are used to understand the pathophysiology of the different forms of epilepsy and their comorbidities, to identify biomarkers, and to discover new antiepileptic drugs...

Fares, R. P., Belmeguenai, A., Sanchez, P.E. et al. 2013. Standardized environmental enrichment supports enhanced brain plas

Environmental enrichment of laboratory animals influences brain plasticity, stimulates neurogenesis, increases neurotrophic factor expression, and protects against the effects of brain insult. However, these positive effects are not constantly observed, probably because standardized procedures of...

Delgado San Martin, J. A., Worthington, P., Yates, J. W. T. 2015. Non-invasive 3D time-of-flight imaging technique for tumour

Subcutaneous tumour xenograft volumes are generally measured using callipers. This method is susceptible to inter- and intra-observer variability and systematic inaccuracies. Non-invasive 3D measurement using ultrasound and magnetic resonance imaging (MRI) have been considered, but...

Bailoo, J. D., Murphy, E., Varholick, J. A. et al. 2018. Evaluation of the effects of space allowance on measures of animal welfare in laboratory mice. Scientific Reports 8, 713.

We studied how space allowance affects measures of animal welfare in mice by systematically varying group size and cage type across three levels each in both males and females of two strains of mice (C57BL/6ByJ...

Joshi, S., Pillay, N. 2016. Personality predicts the responses to environmental enrichment at the group but not within-groups in stereotypic African striped mice, Rhabdomys dilectus. Applied Animal Behaviour Science 182, 44-52.

Environmental enrichment is used to enhance the well-being of captive animals and to prevent or reduce stereotypic and other abnormal behaviours. However, environmental enrichment does not always succeed in its intended purpose. We investigated whether...

Gaskill, B. N., Stottler, A., Pritchett-Corning, K. R. et al. 2016. He’s getting under my skin! Comparing the sensitivity and specificity of dermal vs subcuticular lesions as a measure of aggression in mice.

Aggression is the leading cause of death in young laboratory mice, representing a major welfare issue. Many of the experimental measures used in traditional aggression research, especially those focusing on territorial aggression (e.g., resident/intruder) are...
