Terrestrial Data

Shrub Site


  • Plant biomass/production/chemistry Plant
    biomass measurements near Toolik Lake, Alaska for moist tundra, wet
    sedge, tall shrub, and dry heath. Some harvests include total nitrogen
    and phosphorus.
  • Plant communities and plant species list for area around Toolik Lake
  • Plant phenological and growth data. Leaf growth and phenology data from experimental plots near Toolik Lake
    and the long term data set of flowering abundance and nutrient content
    of Eriophorum vaginatum. The flowering abundance data are from
    observations at 34 sites, spanning 5.5 degrees latitude and 1050 m
    elevation in northern and central Alaska; collected since 1979 and
    annually since 1989.
  • Reflectance data sets from around Toolik region including vegetation indices calculated from canopy reflectance spectra.
  • Soil properties and chemical composition and extractable nutrients:
    Extractable NH4-N and NO3-N (2 N KCl), PO4-P (0.025 NHCl) and pH (0.01 M
    CaCl2); Carbon, nitrogen and phosphorus content; thaw depth; del C-13,
    del N-15; ergosterol concentration for soils near Toolik, along the
    Dalton Highway and Abisko, Sweden.
  • Soil microfuna and microflora- includes bacteria, fungi, protozoa, nematodes, rotifers, tardigrades.
  • Invertebrates (spiders, insects and slugs
  • Trace Gases Ecosystem respiration (ER: or CO2 flux), methane (CH4) fluxes and net
    ecosystem production (NEP) near Toolik Lake, Alaska, comparing effects
    of temperature, moisture and nutrients on tundra C balances.
