Life history variation in gametophyte populations of the moss Ceratodon purpureus (Ditrichaceae).

The life cycles of mosses and other bryophytes are unique among land plants in that the haploid gametophyte stage is free-living and the diploid sporophyte stage is ephemeral and completes its development attached to the maternal gametophyte. Despite predictions that populations of haploids might contain low levels of genetic variation, moss populations are… CONTINUE READING
