This thesis addresses how animals cope with unpredictability by testing how environmental stability changes the behaviour of zebrafish (Danio rerio) in two complementary experiments. In Experiment 1, fish lived for three months in either a Dynamic environment (water temperature, feeding times, habitat complexity, group size, and membership fluctuated) or a Stable environment (all factors constant). Across seven behavioural assays, measuring individual behavioural differences, collective movement, social memory, and information use, Dynamic condition fish were found to be more sensitive to social cues and more likely to conform to recent social information, independent of the quality of the information …

Animals form groups for a variety of reasons, primarily as a way to increase access to food, mates, and safety. An important attribute of these groups is their personality composition. Personality is defined as repeatable traits over time and context, and has been found across multiple taxa. Traits have been found to be heritable, and are thus a unit for natural selection to act upon. Having a heterogeneous group may be beneficial for survival in a changing environment. The question of how the personality composition of the group affects group behaviour has rarely been asked in the field of animal …

Snakes are often considered non-social animals. However, this is mostly an untested assumption and the limited research that has been done has shown that snakes interact socially when given the opportunity. Here, the complexity of snake social interactions was explored through a social cognition and personality lens. Group and individual behavioural assays were used to explore flexibility and consistency in social interactions. The results provide evidence that elucidate the function, development, and evolution of these behaviours in snakes. In the first experimental chapter, chapter 2, social network analysis was used to provide a detailed description of aggregation behaviour in 4 …
