Carbon dioxide response curve, dark respiration, specific leaf area, and leaf nitrogen data for the 2014 Eriophorum vaginatum reciprocal transplant gardens at Toolik Lake and Sagwon, AK, collected in 2016.

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 (SAG, 69°25′26″N, 148°42′49″W) were transplanted.  Half the transplanted tussocks were grown under ambient conditions, while the other half were exposed to passive warming supplied by open-top chambers (OTC).

Effects of shading on tundra vegetation senescence at Toolik Lake, Coldfoot, Sagwon - Alaska 2016

Data on the effects of shading tundra vegetation from the sun when it is low in on the horizon in the north. If light quality was altered through shading, phenology might be affected. Senescence (color change) was measured for the common tundra species.

Eriophorum vaginatum leaf length 2015-2017 from 2014 common gardens established at Toolik Lake, Coldfoot, and Sagwon - Alaska

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 of Eriophorum vaginatum leaves in the reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon- Alaska in 2016

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.

Litter decomposition from 2014 reciprocal transplant garden Toolik Lake, Coldfoot, and Sagwon, Alaska 2016

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.

Normalized difference vegetation index and Leaf area index of tussocks from reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon, Alaska 2016

Normalized difference vegetation index (NDVI)  and Leaf area index (LAI) data from tussocks in the reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon in 2016.

Air and soil temperature in warmed and control plots of 2014 reciprocal transplant gardens Toolik Lake, Coldfoot, and Sagwon, Alaska 2015 and 2016

Air and soil temperatures from iButtons located at reciprocal transplant gardens at Toolik Lake, Coldfoot, and Sagwon in 2015 and 2016. The reciprocal transplant gardens at Coldfoot (CF), Toolik Lake (TL), Sagwon (SG) Each plot contains three tussocks, 30-50 centimeters apart
