We review the evidence for a link between consistent among-individual variation in behaviour (animal personality) and the ability to win contests over limited resources. Explorative and bold behaviours often covary with contest behaviour and outcome, although there is evidence that the structure of these 'behavioural syndromes' can change across situations. Aggression itself is typically repeat...
Many species show considerable variation in behaviour among individuals. We show that some behaviours are largely deterministic and predictable with mathematical models. We propose a general differential equation model of behaviour in field populations and use the methodology to explain and predict the dynamics of sleep and colony attendance in seabirds as a function of environmental factors. O...
Remote laboratories can provide distant learners with practical acquisitions which would otherwise remain precluded. Our proposal here is a remote laboratory on a behavioural test (open field test), with the aim of introducing learners to the observation and analysis of stereotyped behaviour in animals. A real-time video of a mouse in an experimental arena is streamed over the Internet from a s...
Poor communication between academic researchers and wildlife managers limits conservation progress and innovation. As a result, input from overlapping fields, such as animal behaviour, is underused in conservation management despite its demonstrated utility as a conservation tool and countless papers advocating its use. Communication and collaboration across these two disciplines are unlikely t...
New experimental evidence shows that policing behaviour by dominant monkeys stabilizes and integrates macaque societies.
Abuse of anabolic androgenic steroids (AAS) has been linked to psychiatric and physiological complications in humans. Studies have further found a relationship between AAS abuse and abuse of alcohol and other drugs. The main objective of this animal experimental thesis was to examine to what extent the AAS compound nandrolone decanoate (ND; Deca-Durabol [15 mg/kg/day for 2 weeks]) induces behav...
Using cooperation in chimpanzees as a case study, this article argues that research on animal minds needs to steer a course between 'association-blindness'--the failure to consider associative learning as a candidate explanation for complex behaviour--and 'simple-mindedness'--the assumption that associative explanations trump more cognitive hypotheses. Association-blindness is challenged by the...
The field of collective animal behaviour examines how relatively simple, local interactions between individuals in groups combine to produce global-level outcomes. Existing mathematical models and empirical work have identified candidate mechanisms for numerous collective phenomena but have typically focused on one-off or short-term performance. We argue that feedback between collective perform...
Over the last few decades the nature of farming has changed dramatically with small labour intensive farms being replaced by large, highly automated farms. With this change in the way things are done comes a new concern for animal welfare. Traditionally a skilled stock-man would look after a relatively small number of animals and have much direct contact with them on a daily basis. On the moder...
