Dataset landingpage: BioBasis Nuuk - Vegetation - Fluorescence of vegetation

Dataset specification

  • Title: BioBasis Nuuk - Vegetation - Fluorescence of vegetation
  • Description: The effect of increased UV-B radiation on plant stress is monitored indirectly by measuring chlorophyll fluorescence in three series of plots: Controls, plots with a filter excluding UV-B, and filter controls with a film without exclusion of UV-B. Measurements of chlorophyll fluorescence are carried out on Betula nana and Vaccinium uliginosum in a mesic dwarf shrub heath dominated by Empetrum nigrum and with B. nana and V. uliginosum as subdominant species. For further details, please refer to the newest BioBasis manual available at the website. Vegetation:Vegetation BioBasis Nuuk:The BioBasis programme monitors the dynamics of organisms and biological processes in the terrestrial and limnic ecosystems at Zackenberg and Nuuk. The BioBasis programme plays a central role in the development and implementation of the Circumpolar Biodiversity Monitoring Programme (CBMP) http://www.caff.is/monitoring across the Arctic.
