Data for "Spatiotemporal variability in precipitation-growth relations of Betula nana in the Siberian lowland tundra"



Data files and R code used to perform climate-growth analysis on tree rings of the Arctic dwarf shrub Betula nana sampled in topographically contrasting sites at the Kytalyk station in North-eastern Siberia. The purpose of the study was to assess whether associations between annual climate variables and shrub growth (evident from tree rings) varied over decadal timescales and spatial contrasts. We used moving-window orthogonalized partial least squares regression and supporting analyses. While associations of shrub growth and temperature were consistent across time and space, associations of shrub growth and precipitation were not.
