Animal personalities and behavioural syndromes have overarching implications for individual survival, fitness and cooperative task participation. In social spiders, personality in boldness and aggression, and their association into behavioural syndromes, are thought to play a role in individual participation and task specialisation in collective behaviours, such as prey capture. However, recent retractions...
Animals can learn about the value of resources and predation risk by exploring novel environments or exploring novel stimuli in their regular environments. Still, there is a disconnect in the way that exploration has been defined and measured; exploration is defined in terms of information acquisition, while measured in terms of movement speed and diversity of contacted items in a novel environment...
Offspring provisioning and nest defence are important forms of parental care. In birds, parents that engage in nest defence behaviour have to interrupt nestling provisioning with potentially harmful consequences for offspring growth and condition. To maximize fitness, parents should trade off optimal levels of offspring provisioning versus nest defence, but relatively little is known about how parents...
Research on behavioural syndromes (consistent individual differences in suites of correlated behaviours) requires formal statistical methods to describe and compare syndrome structures. We detail the shortcomings of current methods aimed at describing variation in behavioural syndromes, such as multiple pairwise correlations and principal components analysis (PCA). In their place we propose an alternative...
