Data from: Integrating demographic niches and black spruce range expansion at subarctic treelines
Abstract When investigating relationships between species’ niches and distributions, niches can be divided demographically, resulting in unique niches for different life stages. This approach can identify changing substrate requirements throughout a species’ life cycle. Using non-metric multidimensi...

Using non-metric multidimensional scaling, we quantified microsite conditions associated with successful recruitment in the tundra landscape and successful seed production amongst adult trees of black spruce ( Picea mariana ) at subarctic treeline in Yukon, Canada to assess how life stage-specific requirements may impact the distribution of this widespread boreal tree species.
