Supplemental Information
STUDY NOTES: Tree ring sampled; In four stands, cores were taken from the nearest black spruce (with DBH greater than ~5 cm to ensure a non-destructive core sample) every 10 m along three parallel 90 meter transects, spaced 25 m apart ? a total of 10 trees per transect. Where there were not trees present within a 5 m radius of a sampling point, the transect was extended by an additional 10 m until 10 trees were sampled. Subset of trees used in delta 13C analysis. NOAA Template Raw Measurements file added 2020-11-18.
ABSTRACT SUPPLIED BY ORIGINATOR: Northwestern Canada's boreal forest has experienced rapid warming, drying, and changes to permafrost, yet the growth responses and mechanisms driving productivity have been understudied at broad scales. Forest responses are largely driven by black spruce - the region's most widespread and dominant tree. We collected tree-ring samples from four black spruce-dominated sites across 15 degrees of latitude, spanning gradients in climate and permafrost. We investigated (1) differences in growth patterns, (2) variations in climatic drivers of growth, and (3) trends in water use efficiency (WUE) through 13C isotope analysis from 1945 - 2006. We found positive growth trends at all sites except mid-latitude, where rapid permafrost thaw drove declines. Annual growth was lowest at the tree limit site and highest at the treeline. Climatic drivers of these growth patterns varied; positive growth responses at the northerly sites were associated with warmer winters, whereas d13C trends and climate-growth responses at mid-latitude sites indicated growth was limited by moisture availability. d13C signatures indicated increased WUE at the southernmost site, with no significant trends at northern sites. These results suggest that warming will increase growth of trees at black spruce's northern extent, but southerly areas may face drought stress if precipitation does not balance evapotranspiration.
PurposeTree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.
