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. …

Condizione: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | This book carries the list of most pathogenic vector mosquitoes, and their biology, disease transmissions, biological control of mosquitoes; recent advance trends and tools used to the control methods of pathogenic vectors in our Tamil Nadu state are also reviewed. Mosquitoes (Diptera: Culicidae) are monophyletic group of true flies, recognizable by their elongate adult mouthparts. The family is a large and abundant group which occurs throughout temperate and tropical regions of the world, and well beyond the Arctic Circle. Mosquitoes are most diverse in tropical forest environments. Mosquitoes are saprophytic nature; in the breeding occurrence females are in need of blood meal for emerging the ovum. Changes in the livestock pattern along with the deforestation, and the loss of biodiversity should be considered while evaluating the consequences of land use changes on emerging disease. Mosquitoes are the majority of transmissions of the most important vector-borne diseases; henceforth we need serious caution to control the mosquitoes.…
