| Abstract | This study aims at analyzing the relationships between the black spruce (Picea mariana Mill. BSP) radial growth response to climate over a wide territory on the northern Quebec-Labrador peninsula's
boreal forest. Firstly, a hierarchical cluster analysis was conducted to detect the affinities among 93 black spruce tree-ring width series. Secondly, linear multiple regression analysis, associated with a bootstrap technique, was used to calculate
response functions of the tree-ring series. As a result, spatial affinities among tree-ring series highlight a geographical pattern that can be related to the spatial variability of the tree-ring - climate relationships. Inter-annual growth
variations are governed mainly by temperature variables of the preceding growing season: November temperatures have a negative influence, while April has a positive one for among the westernmost trees, as do December-January for the southernmost
trees. Growing season temperatures (mainly July temperatures) influence only the northernmost and easternmost populations. The response was spatially interpolated using a kriging technique with an external drift. |
