![]() ![]() With the increase of Ca 2+ concentration, the contents of Pro, SP and MDA of lithophytic bryophytes showed a downward-upward-downward trend. The present study aimed to explore the physiological regulation process of karst lithophytic bryophytes under high calcium environment, and to provide scientific basis for revealing the maintenance mechanism of karst biodiversity. The lithophytic bryophytes may have a special mechanism to adapt to the karst high calcium environment. ![]() However, the surface calcium content of bare rock is high. Lithophytic bryophytes grow on the rock surface, change the habitat on the rock surface through biological karstification, and provide a material basis for the growth of other plants.
