Annotated cladogram showing the overlap in climatic niche of sunflower crop wild relatives and future climate space of cultivated sunflower in Northern America. Median percent niche overlap values are shown in purple. Leaf economics trait data which explain physiological syndromes differences between species, and geographically correlate with environmental variables such as average temperature and precipitation are shown in green, and an index of fungal disease resistance for each CWR are shown in red (See in Fig. 1 and methods for more details). Gaps in the plots indicate no data.
