Burn Terrestrial Data
Abstract
Adrian V Rocha, 2021 Tussock (Eriophorum vaginatum) density, mortality, and rodent-herbivore activity in moist acidic tussock tundra at the site of the 2007 Anaktuvuk River fire and nearby unburned tundra, measured in 2019. 10.6073/pasta/d25053a5e3d579321688f20558e96753
This dataset consists of tussock density, mortality rates and causes, and an assesment of rodent-herbivore activity levels in previously burned (2007 Anaktuvuk River fire) and unburned tussock tundra. Eriophourm vaginatum tussocks were counted every meter within a 1 square meter quadrat along three transects. Cause of tussock mortality, as well as level of rodent herbivory was assessed for each tussock, and rodent herbivore activity was assessed for each quadrat.

Abstract
Ned Fetcher, Jianwu Tang, Michael L Moody, 2019 White spruce trees tagged measured for total height and girth at 10 centimeter height, and leader length, Coldfoot, Alaska 2015, 2016. 10.6073/pasta/88e3e3717e6ced7f4c14aa89518f4613
White spruce seedlings have colonized the site of the Coldfoot transplant garden (CF, 67°15′32″N, 150°10′12″W) since the original garden was established in 1982.  Some trees are 2-3 meter tall. All seedlings and trees within the current (2014) garden were tagged, located with a Global Positioning System (GPS) receiver, and measured in 2015 and 2016 for total height and girth at 10 centimeter height and leader length.

Abstract
William "Breck" Bowden, 1992 Arctic Grayling Growth on the Oksrukuyik Creek near Toolik Field Station, Alaska 1990-2001. 10.6073/pasta/51ca0640049b0d2dc3706b25bdc6d13e
Arctic Grayling were collected at designated stations on the Oksrukuyik from 1990 to current time. Phosphorus addition has occurred from 1991 to 1996; station sites are relative distance from the original 1991 dripper. Grayling were caught, pit tagged, weighed, measured, and then released back into the river.

Adult Arctic Grayling were caught and tagged in the Kuparuk River. A second fishing campaign occurred later in the summer, and any fish that was recaptured was remeasured to determine growth. Phosphorus addition has occurred since 1983; station sites are relative distance from the original 1983 phosphorus dripper. Stations include sites in a reference, recovery, and fertilized reach. Reaches were defined based on the location of phosphorous addition (see methods). Arctic Grayling were caught early in the field season, tagged, and recaptured late in the field season.

Since 1983, the Streams Project at the Toolik Field Station has monitored physical, chemical, and biological parameters in a 5-km, fourth-order reach of the Kuparuk River near its intersection with the Dalton Highway and the Trans-Alaska Pipeline. In 1989, similar studies were begun on a 3.5-km, third-order reach of a second stream, Oksrukuyik Creek. Fish were collected on each river. Station locations, representing kilomter values certain distances from original phosphorus dripper (see method) were noted.
Terrestrial Plant Phenological and Growth Data
Abstract
Laura Gough, 2008 Growth data was collected on one deciduous shrub species on Arctic LTER experimental plots in moist acidic tussock and dry heath tundra 2004, Toolik Field Station, Alaska.. 10.6073/pasta/433d45e29be3c75342ab66182f235d17
Weekly growth of plant species of three growth forms were measured in the ninth year of a long-term experiment at Toolik Field Station. The experimental treatments excluded small and large mammalian herbivores and increased soil nutrients in two arctic Alaskan tundra communities: moist acidic tussock and dry heath. This data set reports the deciduous dwarf shrub species. Please see 2004lggrgram for the tussock-forming and rhizomatous graminoid species growth data.
Laura Gough, 2008 Growth data was collected on four graminoid species on Arctic LTER experimental plots in moist acidic tussock and dry heath tundra 2004, Toolik Field Station, Alaska.. 10.6073/pasta/8997387154a42d594073cd9bc21283cf
