Genetic consequences of fragmentation in "arbor vitae," eastern white cedar (Thuja occidentalis L.), toward the northern limit of its distribution range.

The difference in H o among the populations from the three zones was highly significant ( P = 0.003), as were differences for F is ( P = 0.002) and R elc ( P = 0.005).
