Genetically Constrained Temporal Trajectories of Temperate Forest Airborne Reflectance Spectra

Remote sensing has demonstrated its potential for wide-scale biodiversity monitoring. It overcomes the spatial limitations of ground-based measurements and allows acquiring high-temporal, -spatial and -spectral resolution data. The temporal trajectories of vegetation spectral responses hold information about time-specific physiological and morphological turnover that may express genetic constraints. We investigated the spectral response of individual trees derived from multi-temporal airborne imaging spectroscopy data along with genetic information and climatic variables. By deriving similarities of spectral and genetic distances, we present a multitemporal approach using remote sensing data to improve biodiversity monitoring at the level of genetic diversity within species.
