Peden, R. S. E., Turner, S. P., Boyle, L. A. et al. 2018. The translation of animal welfare research into practice: The case of mixing aggression between pigs. Applied Animal Behaviour Science 204, 1-9.

Aggression between unfamiliar pigs at mixing is a major animal welfare problem in commercial farming. It has been studied since the 1970s and remains an important topic in animal welfare research. Methods to reduce pig...

Ison, S. H., Bates, R. O., Ernst, C. W. et al. 2018. Housing, ease of handling and minimising inter-pig aggression at mixing for nursery to finishing pigs as reported in a survey of North American pork producers.

Inter-pig aggression is a welfare issue that has undergone extensive research. Although management techniques have proven useful in minimising aggression in research settings, it is not known how often these are used on-farm. One objective...

Clegg, I. L., Rödel, H. G., Delfour, F. 2017. Bottlenose dolphins engaging in more social affiliative behaviour judge ambiguous cues more optimistically. Behavioural Brain Research 322, 115-122.

Cognitive bias tests measure variation in emotional appraisal and are validated methods to assess animals’ affective states. However, the link between social behaviours and cognitive bias has not yet been investigated. Bottlenose dolphins are a...

Pasquarelli, N., Voehringer, P., Henke, J. et al. 2017. Effect of a change in housing conditions on body weight, behavior and brain neurotransmitters in male C57BL/6J mice. Behavioural Brain Research 333, 35-42.

The development of modern housing regimes such as individually ventilated cage (IVC) systems has become very popular and attractive in order to reduce spreading of pathogenic organisms and to lower the risk to develop a...

Arakawa, H. 2018. Ethological approach to social isolation effects in behavioral studies of laboratory rodents. Behavioural Brain Research 341, 98-108.

The aim of the present review is to discuss how housing conditions affect behavioral performance in laboratory rodents from an ethological view. Commonly used laboratory rodents such as rats and mice, are originally captured animals...

Donovan, M., Liu, Y., Wang, Z. 2018. Anxiety-like behavior and neuropeptide receptor expression in male and female prairie voles: The effects of stress and social buffering. Behavioural Brain Research 342, 70-78.

Strong social support can negate negative health outcomes – an effect defined as ‘social buffering’. In the present study, using the socially monogamous prairie vole (Microtus ochrogaster), we examined whether the presence of a bonded...

Hellström, G., Heynen, M., Borcherding, J. et al. 2016. Individual consistency and context dependence in group-size preference of Eurasian perch. Behavioural Processes 133, 6-11.

Many fish spend a large part of their life in groups. The size of the group influences potential costs and benefits of group living, and depending on context a fish may prefer different group sizes...

Lalot, M., Ung, D., Péron, F. et al. 2017. You know what? I’m happy. Cognitive bias is not related to personality but is induced by pair-housing in canaries (Serinus canaria). Behavioural Processes 134, 70-77.

Recent studies suggest that cognitive bias could constitute a novel and valid measure of animal welfare. Although interest for a link between personality and cognition is growing, no study to date investigated whether a cognitive...

Harvey, B. S., Dudzinski, K. M., Kuczaj, S. A. 2017. Associations and the role of affiliative, agonistic, and socio-sexual behaviors among common bottlenose dolphins (Tursiops truncatus). Behavioural Processes 135, 145-156.

Little is known about the specific behavioral exchanges that occur on a day-to-day basis between dyads of common bottlenose dolphins (Tursiops truncatus). This study assesses the proportion of time dyads spend in proximity (within ∼2...

Silva de Souza Matos, L., Palme, R., Silva Vasconcellos, A. 2017. Behavioural and hormonal effects of member replacement in captive groups of blue-fronted amazon parrots (Amazona aestiva). Behavioural Processes 138, 160-169.

Social species in captivity may face allostatic overload due to artificial grouping and other social constraints. In rescue centres, groups of psittacines are constantly mixed due to the arrival and/or release of individuals; this procedure...
