Geographical distribution of allozyme variation in relation to post‐glacial history in Carex digitata, a widespread European woodland sedge
Aim To investigate the distribution, and broad‐scale geographical patterns, of variation, in the widespread boreo‐nemoral woodland herb Carex digitata throughout its native European range. To interpret the revealed geographical pattern of variation in terms of glacial survival, post‐glacial migratio...
