From the general introduction: The Ehinodermata is one of the best characterized and most distinct phyla of animal kingdom Bather, 1900. The echinoderms being common and conspicuous marine animals have been known since ancient times. They are found at every ocean depth from the intertidal zone to the abyssal zone. The first definitive members of the phylum appeared near the start of the Cambrian period. The echinoderms are important both biologically and geologically: biologically because few other groupings are so abundant in the biotic desert of the deep sea, as well as the shallower oceans, and geologically as their ossified skeletons are major contributors to many limestone formations, and can provide valuable clues as to the geological environment.

Hardcover. Condizione: New. 1st Edition. The tropical forest ecosystems are one of the most diverse and rich in biological diversity on earth. The tropical rainforests of India are found in the Andaman and Nicobar Islands, the Western Ghats, and North-eastern India. India is exceptionally rich in biodiversity, and considered as one of the 17 mega-biodiversity countries in the world. Of the 34 biodiversity hotspots identified in the world, India cover four biodiversity hotspots namely, the Himalaya, Indo-Burma, Western Ghats and Sri Lanka and Andaman and Nicobar Islands. India occupies about 2.4 per cent of the world's land area and supports about 8 per cent of the world's total species, including 47,000 species of flowering plants, 4833 vertebrates and 68,389 arthropods. In 16 chapters, reputed experts in their field describe the various aspects in the tropical forest ecosystem of India. Key aspects on the floristic diversity of tropical evergreen forests of various ecosystems are discussed. This book will be of great help to researchers and field scientists as it is a document of this unique habitat of India. (jacket).

From the foreword: The Andaman and Nicobar Islands, popularly known as 'Bay Islands' are situated in the Bay of Bengal, mid way between peninsular India and Mayanmar, spreading like a broken necklace in the North-South direction. These islands are located between 6 45 and 13 41 N latitudes and 92 12 and 93 57 E longitudes. There are 572 islands in all which lie in North-South direction in the Bay of Bengal. The total geographic area of Andaman and Nicobar Islands is 8249 km2, of which Andaman group covers 6408 km2 while Nicobar group covers 1841 km2. The maximum altitude of these islands is 732m at Saddle Peak in North Andaman. Their geology is mainly limestone, sandstone, and clay. There are two volcanic islands, namely Narcondum Island and Barren island. The former is now apparently extinct while the latter is still active. The climate is typically tropical and is always warm, but with sea-breezes. The tropical hot and humid climate with abundant rains has resulted in very luxuriant and rich vegetation of tropical rain forests. This archipelago is considered as a paradise of biological diversity. Out of 1340 species of birds recorded from Indian subcontinent, 21 per cent are found in Andaman and Nicobar Islands. A total of 284 species of birds belonging to 56 families under 17 orders were reported from A & N Islands. Of the recorded species, 155 species were residents, 58 local migrants, 64 trans-continental migrants, 6 vagrants and one species a straggler. Of the 284 species of birds, 105 are endemics at species and subspecies levels. Of the 142 endemic bird species of the Indian subcontinent, 28 are distributed in Andaman and Nicobar Islands. Though the A & N Islands form only 0.25 per cent of the landmass of India, they support 12 per cent of the endemic avifauna.
