Reading light: leaf spectra capture fine‐scale diversity of closely related, hybridizing arctic shrubs
Summary Leaf reflectance spectroscopy is emerging as an effective tool for assessing plant diversity and function. However, the ability of leaf spectra to detect fine‐scale plant evolutionary diversity in complicated biological scenarios is not well understood. We test if reflectance spectra (400–24...
