# Abstract: Growth in arctic vegetation is generally expected to increase 
#  under a warming climate, particularly among deciduous shrubs. 
#  We analyzed annual ring growth for an abundant and nearly 
#  circumpolar erect willow (Salix lanata L.) from the coastal 
#  zone of the northwest Russian Arctic (Nenets Autonomous Okrug). 
#  The resulting chronology is strongly related to summer 
#  temperature for the period 1942?2005. Remarkably high 
#  correlations occur at long distances (>1600 km) across 
#  the tundra and taiga zones of West Siberia and Eastern Europe.
#  We also found a clear relationship with photosynthetic activity 
#  for upland vegetation at a regional scale for the period 1981-2005, 
#  confirming a parallel 'greening' trend reported for similarly 
#  warming North American portions of the tundra biome. 
#  The standardized growth curve suggests a significant 
#  increase in shrub willow growth over the last six decades. 
#  These findings are in line with field and remote sensing studies 
#  that have assigned a strong shrub component to the reported greening 
#  signal since the early 1980s. Furthermore, the growth trend agrees 
#  with qualitative observations by nomadic Nenets reindeer herders 
#  of recent increases in willow size in the region. The quality of 
#  the chronology as a climate proxy is exceptional. Given its wide 
#  geographic distribution and the ready preservation of wood in 
#  permafrost, S. lanata L. has great potential for extended 
#  temperature reconstructions in remote areas across the Arctic.
