Percent carbon, percent nitrogen, del13C and del15N of above ground plant and belowground stem biomass samples from experimental plots in moist acidic and moist non-acidic tundra, 2000, Arctic LTER, Toolik Lake, Alaska.
Percent carbon, percent nitrogen, del13C and del15N were measured from above ground plant and belowground stem biomass samples from experimental plots in moist acidic and moist non-acidic tundra. Biomass data are in 2000lgshttbm.dat.
Arctic LTER 2001: Relative percent cover was measured for plant species on Arctic LTER experimental plots in moist acidic and moist non-acidic tundra.
Relative percent cover was measured for plant species on Arctic LTER experimental plots in moist acidic and moist non-acidic tundra.
Above ground plant and belowground stem biomass in moist acidic and non-acidic tussock tundra experimental sites, 2001, Arctic LTER, Toolik Lake, Alaska.
Above ground plant and belowground stem biomass was measured in moist acidic and non-acidic tussock tundra experimental sites. Treatments sampled were control plots and plots amended with nitrogen and phosphorus.

Stems were measured, and aged from Ledum palustre and Salix pulchra on LTER Moist Acidic Tussock Tundra 1981 plots summer 1990, Toolik Lake Filed Station, AK.
Stems were measured, and aged from Ledum palustre and Salix pulchra species on treated plots at Toolik Lake, AK. Stem secondary growth in per cent per year was estimated from the slope of weight per unit length vs. age.
Phenological stages of deciduous plants were observed at a long term experimental moist acidic tussock tundra site, Arctic LTER 1996 Toolik Lake, AK.
Phenological stages of deciduous plants were observed at a long term experimental moist acidic tussock tundra site (Arctic LTER) near Toolik Field Station, AK. Also, ITEX maximum growth measurements were recorded on August 19th (moist tussock tundra). Experimental treatments at each site included factorial NxP, greenhouse and shadehouse and were begun in 1989. See 96gspheg.html and 96gsphsg. html for phenological data on evergreen and sedge species.
In situ soil respiration measured in the LTER treatment plots in moist acidic tussock and moist non-acidic tussock tundra, Toolik Field Station, North Slope Alaska, Arctic LTER 2002.

Plant biomass in moist acidic tussock tundra experimental small mammal exclosures, 1999 Arctic LTER Toolik, Alaska.
Above ground plant and below ground stem biomass was measured in Arctic LTER tussock tundra experimental small mammal exclosures. Treatments included Control, Nitrogen plus Phosphorus with both fenced and unfenced plots. In addition a moist non-acidic tussock tundra site was harvested. Leaf areas were also measured for each quadrat but are in a separate file.
Soil radiocarbon from moist acidic tussock and erect shrub tundra at Toolik Field Station
<p>Soil radiocarbon data from one moist acidic tussock tundra and one erect shrub tundra (<em>Betula glandulosa</em>) site in the northern foothills of the Brooks Range near Toolik Field Station, AK, USA. Data covers the active layer. The tussock site is located on Itkillik I glacial deposits. The shrub site is a palsa within a riparian area, and likely underwent a relatively recent shift in vegetation cover from wet sedge to shrub. (The soil profile is made up of two different soil types within the active layer).</p>
