Population Structure of Dicranum Elongatum in Northeastern Regions of Wapusk National Park, Manitoba, Canada
Genetic variation and gene flow is examined for Dicranum elongatum on the beach ridge system along the Hudson Bay Lowlands in Wapusk National Park in Manitoba, Canada. Samples were collected from 10 quadrats from each of 14 transects on the beach ridge crests and in the low-lying troughs between bea...
