Ecological Adaptations - Mesophytes - These are land plants which grow in moist habitats and need well aerated soils. They prefer soil and air with moderate humidity. They avoid soils with standing water and soils containing great abundance of salts. They have some special featu..

a) Crustose - lichen stage Lichen species like Graphis Rhizocarpon, Rinodina and Lacanora forms the pioneer community in a lithosere, as they can tolerate desiccation. Organic acids produced by lichens corrode the rock surface and release minerals for proper growth of lichens. Wind borne soil par..

Introduction - The term ecology is derived from two Greek words (oikos - means 'house' or place to live and logos means 'a discussion or study'). Literally, ecology is the study of organism 'at home' in their native environment. The term was first introduced by Reiter in 1868, b..

Many industries such as goldmines, cement industry, iron ore mines, coal mines, bauxite mines have excavated the land to very deep layers to extract the ore. But most of them have never devised any method to cover up the excavations. Many such excavations have spread to several square kilometers a..

Lithosphere (Xerarch) - It is a type of xerosere and involves the ecological succession on bare rock surfaces. Rocky surface is characterized by i) deficiency of water ii) absence of organic matter iii) surface temperatures are very hi..
