Download or read book Ecology and Biogeography in India written by M.S. Mani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the outstanding features of the ecology and bio geography of the Indian region, comprising former British India, Nepal, Bhutan, Ceylon and Burma. It summarizes the results of nearly four decades' studies and field explorations and discussions with students on the distribution of plants and animals, practically throughout this vast area and on the underlying factors. A number of specialists in geology, meteorology, botany, zoology, ecology and anthropology have also actively collaborated with me and have contributed valuable chapters in their respective fields. India has an exceptionally rich and highly diversified flora and fauna, exhibiting complex composition, character and affinities. Although the fauna of the Indian region as a whole is less completely known than its flora, we are nevertheless fairly well acquainted with at least the salient features of its faunal characters to enable us to present a meaningful discussion on some of the outstanding peculiarities of the biogeography of India. A general synthesis of the available, though much scattered, information should prove useful to future students of biogeography throughout the world.

Available in PDF, EPUB and Kindle. Book excerpt: World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.

Download or read book Cyprinid Fishes written by Ian J. Winfield and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range ofbiological adaptations to diverse habitats has evolved. As weIl as living in the conventional habitats of lakes. ponds. rivers. rock pools and the open sea. fish have solved the problems of life in deserts. in the deep sea. in the cold Antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations. we find the most impressive specializations of morphology. physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas. air breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover. fish are of considerable importance of the survival of the human species in the form ofnutritious and delicious food ofnumerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology. but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
Download or read book Species Diversity of Animals in Japan written by Masaharu Motokawa and published by Springer. This book was released on 2016-11-26 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the status quo of the knowledge about the biodiversity in terrestrial, freshwater, and marine animals that live in Japan. Consisting of some 6,800 islands that are arrayed for approximately 3,500 km from north to south, the Japanese archipelago has a complex history in a paleogeographic formation process over time and harbors rich flora and fauna. This work will contribute to establishing a general biogeographic theory in archipelagoes around continental shelves. Facing the ongoing extinction crisis, one of the most important tasks for our generation is to bequeath this precious natural heritage to future generations. As the first step toward this goal, a species list has been compiled through solid, steady alpha-taxonomic work in each taxon. Furthermore, the phylogeography and population genetic structure for each species is elucidated for deeper understanding of the local fauna, the scientific results of which should be the basis for establishing conservation policies and strategies. Also the problem of alien or introduced species is investigated as another threat to the native fauna.Each of the 27 chapters is written by the most active specialist leading the field, thus readers can acquire up-to-date knowledge of the animal species diversity and their formation process of Japanese animals in the most comprehensive form available. This book is recommended for researchers and students who are interested in species diversity, biogeography, and phylogeography.

Download or read book The Taxonomy Systematics and Zoogeography of Hypsibarbus a New Genus of Large Barbs Pisces Cyprinidae from the Rivers of Southeastern Asia written by Walter J. Rainboth and published by Univ of California Press. This book was released on 1996-01-01 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study the author describes Hypsibarbus, a new genus of Asian cyprinid fishes with twelve species, three of them new. A complete set of 45 measurements and 17 counts was taken and analyzed for approximately 250 specimens, including all type material, of more than 1000 specimens encountered, representing most of the major fish collections of the world. The author fully redescribes and illustrates all species in the new genus, and includes keys for their identification. To provide a basis for understanding zoogeographic implications of the phylogeny obtained for Hypsibarbus, the geography and history of the Southeast Asia river basins is discussed in detail.
Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major concern among ecologists in and outside the ASEAN region is the degradation of the environment, and the overexploitation of freshwater and marine resources. There is as yet no indication that freshwater and marine resources are being managed on a sustainable basis, and loss of wetlands, whether freshwater swamps or mangrove swamps, is a major problem in the ASEAN region. Reclamation of mangrove swamps for aquaculture and agriculture seems to be a continuous activity here and the status of marine parks should also be examined in the light of recent resort development acitivities on small islands. This volume contains numerous recommendations for the promotion of ecological studies and regional cooperation in marine, freshwater ecology and conservation, with special emphasis on the common water masses like the Strait of Malacca, Gulf of Thailand and the South China Sea.
