Fig. 1: Origin of sampled black spruce provenances.

From: Annual aboveground carbon uptake enhancements from assisted gene flow in boreal black spruce forests are not long-lasting

a Squares: Locations of the Mont-Laurier (ML) and Chibougamau (CH) common gardens along with the locations of the black spruce seed origins (dots), superposed on the species’ range limits90. Background colors: mean annual growing degree days above 5 °C (GDD5, °C) computed over 1961–1990. b, c Percent survival (%) of individuals as of year of sampling in each common garden as a function of the seed provenance distribution. d Pie chart: Averaged genetic admixture proportions on a given cluster corresponding to Western (gWest), Central (gCenter), and Eastern (gEast) lineages. The admixture proportions are used as a proxy to describe among population genetic differences. Background colors: mean annual precipitation (MAP, mm).
