Data on Eriophorum vaginatum leaf length collected from common gardens established at Toolik Lake, Coldfoot, and Sagwon in 2014 with tussocks from  Coldfoot, Toolik Lake, and Sagwon. Data collected during the growing seasons of 2015, 2016, and 2017

Quantum yield of Photosystem II  estimated from chlorophyll fluorescence of Eriophorum vaginatum leaves from tussocks in the reciprocal transplant gardons at Toolik Lake, Coldfoot, and Sagwon in 2016. A single transplant tussock per plot was repeatedly measured through the season.

Data on litter decomposition of Eriophorum vaginatum leaves collected at Toolik Lake, Coldfoot, and Sagwon and distributed to all three sites. Litter bags from the three populations were deployed at CF (8/26/15), TL (8/24/16) and SG (8/25/16) sites approximately 40 meter away from the main transplant gardens (east of CF, east of TL and west of SG) into 5 blocks with 4 intended harvests at each plots.

Transplant gardens at Toolik Lake and Sagwon were established in 2014.  At each location, 60 tussocks each from ecotypes of Eriophorum vaginatum from Coldfoot (CF, 67°15′32″N, 150°10′12″W), Toolik Lake (TL, 68°37′44″N, 149°35′0″W), and Sagwon (SG, 69°25′26″N, 148°42′49″W) were transplanted. At the reciprocal transplant gardens, ion exchange membranes were used to measure nutrient availability over two time periods: Early season (June) and mid season (July). Membranes were deployed in the field for either 20 or 21 days, depending on travel constraints.

Data on Eriophorum vaginatum leaf length collected from a common garden established at Toolik Lake in 2011 with tussocks from No Name Creek, Coldfoot, Eagle Creek, Toolik Lake, Sagwon, and Prudhoe Bay. Data collected during the growing seasons of 2015 and 2016. Results published in Parker, T. C., J. Tang, M. B. Clark, M. M. Moody, and N. Fetcher. 2017. Ecotypic differences in the phenology of the tundra species Eriophorum vaginatum reflect sites of origin. Ecology and Evolution 7: 9775-9786. doi: 10.1002/ece3.3445
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
Jennie DeMarco, Michelle Mack, 2013 Mass, C, N, and lignin from litter decomposed across a shrub gradient and with snow manipulations near Toolik Field Station between 2003 and 2009.. 10.6073/pasta/badba3735996e3de4cd02ee4bd1cfd5c
In arctic tundra near Toolik Lake, Alaska, we incubated a common substrate in a snow addition experiment to test whether snow accumulation around arctic deciduous shrubs altered the environment enough to increase litter decomposition rates. We compared the influence of litter quality on the rate of litter and N loss by decomposing litter from four different plant functional types in a common site. We used aboveground net primary production values and estimated k values from our decomposition experiments to calculate community-weighted mass loss for each site.
