Oikos, Volume 2025, Issue 12, December 2025.Closely related species living in sympatry are often partitioned into divergent ecological niches. Such specialization can be enabled by the evolution of divergent traits enhancing adaptation to different niches. In this study, we investigate the partitioning of closely related butterfly species into different forest strata and daily activity time and ...
