The Recent Development of a Mixed Shrub and Conifer Community on a Rapidly Emerging Coast (Eastern Hudson Bay), Subarctic Quebec, Canada
This paper presents an analysis of the relation between shrub mat development and the expansion of conifer forest margins over a rapidly emerging coast (average rates ranging between 1.1 and 1.5 cm/year) in response to postglacial isostatic adjustment. Shore emergence stimulates the downward expansi...
