Illegal motorcycle street racing is a threat to civil society – it symbol of adolescents' inner rebellion who channelled their unfulfilled desire through aggressive behaviour on the road, causing significant social and economic impact. Aggressive behaviours have been associated with prohibited substances intake, lack religious knowledge, problematic family structures, school failure. In this qu...

Research is needed to validate lesions recorded at meat inspection as indicators of pig welfare on farm. The aims were to determine the influence of mixing pigs on carcass lesions and to establish whether such lesions correlate with pig behaviour and lesions scored on farm. Aggressive and mounting behaviour of pigs in three single sex pens was recorded on Day -5, -2, and -1 relative to slaughte...

Lesions in the archistriatum, the avian homologue of the amygdala, and the nucleus striae terminalis suppress the aggressive behaviour and enhance the avoidance behaviour of selected aggressive pigeons. Similar limbic circuits thus seem to control aggression in birds and mammals. It is well documented in mammals that the limbic system plays an important role in the control of aggression. For bi...

BACKGROUND Childhood hyperactivity has previously been found to be closely connected to subsequent alcohol problems and violent offending among men considered to be without major mental disorders. For others, these associations might be moderated or confounded by other factors, predominantly comorbid conduct disorder. AIMS The purpose of the study was to investigate aspects of childhood hyper...

Research in the past decade has established the existence of consistent individual differences or 'personality' in animals and their important role in many aspects of animal behaviour. At the same time, research on honest signalling of aggression has revealed that while some of the putative aggression signals are reliable, they are only imperfectly so. This study asks whether a significant port...

Breeding for behavioural traits may improve pig welfare and breeding high production decrease welfare. Maternal behaviours important piglet includes savaging, crushing nursing. Behaviours of importance pigs slaughter feeding behaviour, tail biting aggressive behaviour. These are complex large amounts data needed accurate genetic evaluation selection.

Repeatable behavioural traits ('personality') have been shown to covary with fitness, but it remains poorly understood how such behaviour-fitness relationships come about. We applied a multivariate approach to reveal the mechanistic pathways by which variation in exploratory and aggressive behaviour is translated into variation in reproductive success in a natural population of blue tits, Cyani...
