Fig. 1. Carbon isotope ratios (¹³C; ) in wing membrane, blood and hair of Leptonycteris curosoae (A) and Glossophaga soricina (B) compared to the initial diet originating from plants with a C₃ photosynthetic pathway. Data are presented as box plots with the border of the box representing the 25% and 75% percentiles, the T-mark shows the 10% and 90% percentiles and the outermost points the 5% and 95% percentiles. The thin line within the box indicates the median.
