Abstract Over the last two decades, considerable research has built on remote sensing of spectral diversity to assess plant diversity. The variation hypothesis (SVH) proposes that spatial in reflectance data an area is positively associated with While SVH exhibited validity dense forests, it performs poorly highly fragmented and temporally dynamic agricultural landscapes covered mainly by grasslands. Such underperformance can be attributed mosaic-like structure human-dominated fields varying...
The habitat use of wild ungulates is determined by forage availability, but also the avoidance predation and human disturbance. They should apply foraging strategies that provide most energy at lowest cost. However, due to data limitations scale movement trajectories, it not clear what extent even well-studied species such as red deer (Cervus elaphus) trade-off between quality quantity, especially in heterogeneous alpine habitats characterized short vegetation periods. We used remote sensing...
Accurate retrieval of biophysical variables is crucial for characterizing properties (i.e. traits) plant canopies and capturing their spatiotemporal changes. Optical remote sensing offers the unique possibility frequent large-scale mapping due to strong associations between spectral data optical traits. One approach formally predict remotely based on hybrid retrieval. In this approach, a radiative transfer model (RTM) used simulate spectra training then machine learning regression utilized...
