Animal personality and sociality
My research interests focus on understanding the role of consistent individual differences in animal behaviour, also known as animal personality, and its crucial link with sociality. In recent years there has been considerable interest in the phenomenon of animal personality and in a wide range of animal species individuals have been found to show large consistent variability in the way they cope with challenges in their environment. Importantly, this variation has been found to have a genetic basis and to be linked to fitness, suggesting that animal personality has important ecological and evolutionary implications. However, as the social environment plays a crucial role in the life of social animals, one cannot fully understand the significance of personality without a firm understanding of the relationship between animal personality and the social environment. It is therefore surprising that very few studies exist that have investigated this link.
The goal of my PhD is to provide a better understanding about the role of animal personality and its under explored but crucial link with sociality. Various of the questions I am currently working on are trying to understand how personality traits relate to the use and reliance on social information, how social feedback may affect individuals with certain traits differently and how that influences leadership, and how conformity behaviour depends on personality and what role this plays in group cohesion and movement. Investigating these questions is not only very exciting, it is very relevant as it has potentially significant ecological and evolutionary consequences for animal decision-making, social group behaviour and the evolution of culture. I work with a variety of species to answer these questions including fish (three-spine and nine-spine sticklebacks) and birds (rooks and jackdaws).
