Anotace knihy

A subject of this work is adaptation in §heterogeneous environments analyzed by applying two §approaches, generalist-specialist and plant strategy §theory, and using several populations of a single §species, wild barley (Hordeum spontaneum Koch). Four §environments were specifically chosen to represent a §gradient of environmental productivity (annual §rainfall) and unpredictability (interannual §variation in rainfall). Plants originating in the §four distinct environments were tested for local §adaptation, and analyzed for the possible mechanisms §by which the adaptation was achieved. I found that §the specialist-generalist approach was not efficient §in analyzing selection process at large-scale §(regional-scale) heterogeneity. On the other hand, §the life history traits, phenotypic plasticity and §competitive ability of plants originating in the §four studied environments were in partial §correspondence with those predicted by Grime s C-S-R §model. A new plant strategy scheme that is based on §the rectangular ordination of environments and has §two ordination axes: adversity (stress) and §environmental unpredictability, is proposed.
