Toolik Lake 2011 common garden leaf length phenology 2015-2016 Alaska

Abstract: 

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

 The 2011 garden comprises tussocks transplanted from No Name Creek (NN), Eagle Creek (EC), Coldfoot (CF), Toolik Lake (TL), Sagwon (SG) and Prudhoe Bay (PB) into a site at Toolik Lake in August 2011. Tussocks were transplanted into 24 plots of 3 tussocks from the same population. The plots of the 6 populations are distributed randomly around the garden in pairs. One of each pair was randomly chosen to be warmed with an open top chamber. The set up of the plots is displayed on the right, a red border around the  label indicates that plot was warmed. This garden can be found between the reciprocal '2014' transplant garden and the 'historic' LTER fertilizer plots.

One tiller on one tussock per plot was tagged at its base using a plastic zip tie. The dead, brown leaves were clipped from the tiller and the total length and the green length of each live leaf was measured to the closest 0.5 cm approximately weekly.  This was done by placing the ruler as far into the tussock as possible and measuring from that point to the end of the leaves.

#A note on some leaf lengths

Some leaves were measured with rulers with irregular extra lengths on the ruler, therefore this amount (e.g. 8 mm) was subtracted from the measured amount
