Urbanization is one of the major causes of the global biodiversity crisis with reptiles being particularly vulnerable, due to factors such as habitat loss and road mortality. Behaviour plays a crucial role in determining the success of urban animals, but behavioural responses to urbanization are rarely studied in reptiles. I studied the differences in aggression, boldness, and exploration in painted turtles (Chrysemys picta) living in urban and undisturbed areas. I hypothesized that aggression, boldness, and exploration would increase in urban painted turtles. I studied painted turtles from 24 sites across an urban to undisturbed gradient in Ottawa, Ontario, Canada over the summers of 2021 and 2022. I captured turtles with hoop nets and tested their behaviour in the field, and the repeatability of their behaviour in the laboratory. I found that urbanization had a statistically significant, positive effect on painted turtle aggression and boldness, and no effect on exploration. Overall, I determined that urbanization is affecting painted turtle behaviour, but further research is required to better understand the factors behind this.
