Partitioning plant spectral diversity into alpha and beta components

摘要: Plant spectral diversity - how plants differentially interact with solar radiation is an integrator of plant chemical, structural, and taxonomic that can be remotely sensed. We propose to measure as variance, which allows the partitioning a region, called gamma (γ) diversity, into additive alpha (α ; within communities) beta (β among components. Our method calculates contributions individual bands or features γ-, β-, α-diversity, well communities diversity. present two case studies illustrating our approach identify "hotspots" α-diversity discover spectrally unique areas contribute strongly β-diversity. Partitioning mapping its spatial components has many applications for conservation since high local distinctiveness in composition are key criteria used determine ecological value ecosystems.
