Foliar spectra accurately distinguish most temperate tree species and show strong phylogenetic signal

Abstract: PremiseSpectroscopy is a powerful remote sensing tool for monitoring plant biodiversity over broad geographic areas. Increasing evidence suggests that foliar spectral reflectance can be used to identify trees at the species level. However, most studies have focused on only a limited number of species at a time, and few studies have explored the underlying phylogenetic structure of leaf spectra. Accurate species identifications are important for reliable estimations of biodiversity from spectral data.MethodsUsi… Show more

“…For plants, measurements of traits can include concentrations of foliar pigments (e.g., chlorophyll/m 2 ), leaf mass per area (dry m/area), some nutrients, e.g., nitrogen/leaf area (N/m 2 ) [ 315 , 316 ]. The shape of the spectra can be used to identify specific minerals [ 317 ], soils [ 318 ], or plant species [ 319 , 320 , 321 , 322 , 323 ]. Spectra provide important clues for hydrology [ 302 , 303 , 304 , 324 ], plant physiology [ 50 , 325 , 326 , 327 ], surface biogeochemistry [ 52 , 328 , 329 , 330 , 331 ], ocean and freshwater biology and coastal margins [ 308 , 309 , 332 ], as well as the type of pollution [ 312 , 333 , 334 , 335 ], and type and extent of disasters [ 311 , 313 , 336 , 337 ].…”
