Fear contagion in zebrafish: A behaviour affected by familiarity

Emotional contagion has recently been described in fish but whether it is affected by familiarity is not known. We tested whether the sight of a distressed conspecific elicited fear in zebrafish, Danio rerio, and whether this was modulated by familiarity....

Positive welfare for fishes: Rationale and areas for future study

Traditional animal welfare paradigms have focused on maintaining physical health and mitigating negative impacts to wellbeing. Recently, however, the field has increasingly recognized the importance of positive welfare (i.e., mental and physical states that exceed what is necessary for immediate...

Exercise reward induces appetitive 50-kHz calls in rats

Rats express affective states by visible behaviors (like approach or flight) and through different kinds of ultrasonic vocalizations (USV). 50-kHz calls are thought to reflect positive affective states since they occur during rewarding situations like social play or palatable food....

Attenuation of fear through social transmission in groups of same and differently aged horses

Transmission of fear and attenuation of fear within groups of farm animals remain relatively unexplored, despite the importance for human and animal safety. This paper reports the results of two separate experiments, aiming to explore social transmission of habituation in...

Examining affective structure in chickens: valence, intensity, persistence and generalization measured using a Conditioned Place Preference Test

When measuring animals' valenced behavioural responses to stimuli, the Conditioned Place Preference (CPP) test goes a step further than many approach-based and avoidance-based tests by establishing whether a learned preference for, or aversion to, the location in which the stimulus...

The effects of green odour on domestic dogs: A pilot study

Green odour (a mixture of cis-3-hexenol and trans-2-hexenal), similar to cut grass, has been demonstrated to appease subjects of various species (rats, cattle, humans etc.) subjected to different stressful stimuli. The aim of this study was to investigate whether green...

Is boredom an animal welfare concern?

Boredom, while often casually attributed to non-human animals by both laypeople and scientists, has received little empirical study in this context. It is sometimes dismissed by others as anthropomorphic or a trivial concern in comparison to other welfare problems faced...

Is heightened-shoaling a good candidate for positive emotional behavior in zebrafish?

Zebrafish, a highly-social species of freshwater fish, are widely studied across many fields of laboratory science including developmental biology, neuroscience, and genomics. Nevertheless, as standard housing for zebrafish typically consists of small and simplistic environments, less is known about their...

Effects of exercise and enrichment on behaviour in CD-1 mice

A host of scholarly work has characterized the positive effects of exercise and environmental enrichment on behaviour and cognition in animal studies. The purpose of this study was to investigate the uptake and longitudinal impact of exercise and enrichment on...

Effect of moderate environmental enrichment on commonly used behavioural tests in rats

The environment that laboratory animals are housed in should reflect their natural habitats in a manner that can satisfy their innate physiological and behavioural needs. This includes nest building, hiding, exploring and foraging. Providing environmental enrichment (EE) in order to...
