It discusses the morphology, reproduction, ecological roles, and conservation of lichens, as well as their economic and therapeutic importance. The book also examines the impact of climate change on lichens and their potential as indicators of environmental changes. Intended for researchers and students in botany, chemistry, and environmental science, it provides a detailed account of the taxonomy, physiology, and ecological significance of lichens, offering insights into their role as pioneers in ecological succession and their utility in various industries.Generated by AI.LichensGenerated by AILichenologyGenerated by AILichensLichenology579.7Das Ashoke Kumar1837424Sharma Ajay1057927Kathuria Deepika1837425Ansari Mohammad Javed1837426Bhardwaj Garima1837427MiAaPQMiAaPQMiAaPQBOOK9911019323603321Chemistry, Biology and Pharmacology of Lichen4416157UNINA
