Ecology, Phytogeography and Perennation of Bryophytes in Rajasthan, India

The present study deals with the study of bryophytes in relation to soil and climatic condition broadly speaking three bryoecological zones viz. the arid and semi arid, the plateau and the southern region each having different climatic conditions and vegetation. Abiotic and biotic factors play an important role in the occurrence and distribution of bryophyte vegetation in the state. The availability of water, amount of moisture in the air, temperature, light, elevation, nature of soil and its availability to retain moisture and biotic factors control the distribution of bryophyte species. Sixty four bryophyte species have been collected from different parts and various localities of this state out of which geographically 43 occur in the Western Himalayas, 34 in Eastern Himalayas and 32 in the South India. Further it was reported that plants perennate in adverse climatic condition by the formation of gemmae, tubers, meristematic rolling apical apices and some other vegetative parts of the plants.
