Expressed sex ratio in populations of the moss Hamatocaulis vernicosus (Scorpidiaceae) in the Czech Republic with consideration of its cryptic species.

Abstract

This thesis aims at sex expression and sex ratio in cryptic species of a rare fen moss Hamatocaulis vernicosus. The sex expression and expressed sex ratio were compared at various hierarchical levels. Additionally, micromaps of expressed sex ratio in patches at 21 localities, including 5 localities where both clades co-occur have been created.
