DESCRIPTION:An open question is whether the structure and function of rela
 tively undisturbed ecosystems are inevitable consequences of climate and g
 eology or whether the idiosyncracies of biogeographic and evolutionary pro
 cesses\, including the order and timing of lineage dispersal and diversifi
 cation\, have led to divergent outcomes in ecosystem function. The ecosyst
 em composition and diversity of plant electromagnetic spectra—the patter
 ns of reflected photons from plants—are emerging as important measures o
 f biodiversity\, alongside functional and phylogenetic components. Spectra
  contain abundant information about plant function and are tightly coupled
  to the tree of life. The evolutionary innovations and legacies of biogeog
 raphic history that have contributed to modern plant communities and ecosy
 stems may be revealed from the spectral reflectance of plants and from inc
 reasingly available remote sensing data that provide environmental informa
 tion across spatial and temporal scales. Understanding the context in whic
 h plants evolved and the role of evolutionary history in current ecosystem
  structure and function provides insight into how ecosystems will respond 
 to future environmental changes. These insights combined with advancing me
 thods for detecting and monitoring change in biodiversity and ecosystems c
 an help prioritize conservation and inform strategies for maintaining a ha
 bitable planet in the face of global change.\n\nContact se389@cam.ac.uk fo
