Urban stream syndrome alters habitat complexity. We define complexity as the degree of variation in physical structure, with increasing equating to higher Habitat affects species composition and shapes animal ecology, physiology, behaviour cognition. used a delayed detour test measure whether cognitive processes (motor self-regulation) (risk-taking) female Western mosquitofish, Gambusia affinis, varied structural (low, moderate high) that was quantified visually for nine populations. predicted motor self-regulation risk-taking would increase complexity, yet we found support opposite. Lower habitats offer less refuge potentially leading predation pressure selecting greater by fish self-regulation. Our findings provide insight into how can shape offers broader understanding why some may tolerate conditions urbanized environments.
