Email Steven Mamet (smamet@ualberta.ca) for availability Reference: Mamet, S. and Kershaw, G.P. (Submitted) Radial-growth response of forest-tundra trees to climate: Subarctic Hudson Bay Lowlands. Dendrochronologia. Submitted 23/03/2009. 32 pp. (MS#DENDRO-D-08- 00001R1). NOTES: The effects of climate on radial-growth of Larix laricina (Du Roi) K. Koch, Picea glauca (Moench) Voss and Picea mariana (Mill) BSP were investigated in northern Manitoba. The objective was to characterize spatial and temporal variations in growth of trees across three ecologically distinct regions. Along a 250 km transect 263 trees were sampled (stratified random) in three zones - northern forest (NFOR), central tundra (TUND) and southern forest (SFOR). Samples were collected in August of 2004 and 2005 and NFOR samples were supplemented with cores from a Black spruce wetland and White spruce upland (also available from ITRDB - cana270 and cana272).
