Associated Researcher Erica Stieve Associated Researcher 2005 Above ground plant and below ground stem biomass was measured in the Arctic LTER acidic tussock tundra experimental plots. Treatments included control, nitrogen plus phosphorus amended plots for either 6 or 13 years and vole exclosure plots with or without amends of nitrogen and phosphorus. Alaska biomass productivity nitrogen phosphorus tundra exclosure primary production disturbance inorganic nutrients organic matter populations Acceptance and utilization of LTER data requires that: The Principal Investigator be sent a notice stating reasons for acquiring any data and a description of the publication intentions.

The experimental design is four blocks of 5 x 20 meters plots with randomly assigned treatments within each block. Treatments include control (CT), amended with 10 g per square meter of Nitrogen and 5 g per square meter of phosphorus (NP), simple warming with plastic covered greenhouses (GH), simple warming amended with 10 and 5 g per square meter of nitrogen and phosphorus (GHNP) and 50% shade house with and without 10 and 5 g per square meter of nitrogen and phosphorus added (SH and SHNP). Exclosure plots were setup in July 1996 on extra 5 x 20 meters plots within the four-block design of the 1989 LTER acidic tussock experimental plots. On each plot a 5x10 meter section was fenced with large mesh (4-inch square mesh) and within this fence a 5x5-meter plot was fenced with a small mesh (1/2-inch square mesh). In each block two fenced plots were setup: a plot with no fertilizer and a plot with annual fertilization (NP) treatments of 10 g/m2 Nitrogen (as NH4NO3) and 5 g/m2 Phosphorous (as triple superphosphate). In this biomass harvest only the control, 1989 NP (NP13), GH, GHNP, control small mesh (EX), NP unfenced (NP6), and NP small mesh (EXNP) treatments were sampled. Calculations: Units; Tissue mass data are expressed in g/quadrat (400 cm2). Multiply by 25 to get g/m2. Reference Citations: Shaver, G. R. and F. S. Chapin, III. 1991. Production/biomass relationships and element cycling in contrasting arctic vegetation types. Ecological Monographs 61:1-31. Sampling Description. Biomass quadrats, size 20x20 cm, were taken from Toolik tussock site. Five quadrats were taken from each of four blocks. All aboveground biomass was clipped in 20x20 cm quadrats. Five quadrats were randomly located along line transects in each of four replicate blocks in each treatment. Aboveground biomass is considered "within" the quadrat if it is associated with a meristem that is within the quadrat. Quadrats were sorted within 24 hours into species and then into tissue type. Depending on the harvest, tissue types can be broad categories, i.e. above and below, or more detailed, i.e. inflorescences, new growth, old growth, etc. Leaf area was measured with a LiCor LI-3000A area meter. The samples were dried at 60 degrees C in a drying oven and after several days weighed to nearest milligram. Samples are then returned to Woods Hole for nutrient analysis. Details are given in Shaver and Chapin (Ecological Monographs, 61(1), 1991, pg. 1-31). pers-1 John Hobbie

(508) 289 7496 arc_imr@mbl.edu Information Manager The goal of Arctic LTER project is to predict the future ecological characteristics of the site based upon our knowledge of the controls of ecosystem structure and function as exerted by physical setting and geologic factors, climatic factors, biotic factors, and the changes in fluxes of water and materials from land to water. To achieve this goal the Arctic LTER uses several approaches: Long-term monitoring and surveys of natural variation of ecosystem characteristics in space and time. Includes: climate, plant communities and productivity, thaw depth, stream flow, chemistry of streams and lakes, temperatures of streams and lakes, lake chlorophyll lake productivity, zooplankton abundance. Experimental manipulation of ecosystems for years and decades. Includes: tundra warming, shading, and fertilizing, grazer exclusions, fertilization of lakes and streams, addition and subtraction of predators. Synthesis of results and predictive modeling at ecosystem and watershed scales. Includes: stream N cycling, lake physics, bioenergetics of fish populations, water movement and transfer of DOC and nutrients from land to water, soil respiration, cycling and storage of C in tundra under different scenarios of future climates.

The Arctic LTER research site (68°N and 149°W) is in the foothills region of the North Slope of Alaska and includes the entire Toolik Lake watershed and the adjacent watershed of the upper Kuparuk River, down to the confluence of these two watersheds. This area is typical of the northern foothills of the Brooks Range, with continuous permafrost, no trees, a complete snow cover for 7 to 9 months, winter ice cover on lakes, streams, and ocean, and cessation of river flow during the winter. Tussock tundra vegetation of sedges and grasses mixed with dwarf birch and low willows form the dominant vegetation type with areas of drier heath tundra on ridge tops and other well-drained sites as well as areas of river-bottom willow communities. -149.75 -149.0433 68.8 68.5 610 1360 meter 2002gsttbm.csv Above ground plant and below ground stem biomass in the Arctic LTER acidic tussock tundra experimental plots, 2002, Toolik Lake, Alaska. 2002gsttbm.csv 1 \r\n column , " http://metacat.lternet.edu/das/dataAccessServlet?docid=knb-lter-arc.1398&urlTail=terrest/biomass/data/2002gsttbm.csv Date Date Date of sampling in ddmmyyyy dd-mon-yyyy Site Site Tundra site of sampling Tundra site of sampling Treatment Treatment plot treatment plot treatment Growth Form Growth Form Growth form of species Growth form of species Species Species The species The species Tissue Tissue The tissue type The tissue type Biomass Categroy Biomass Categroy growth category. growth category.
