Available in PDF, EPUB and Kindle. Book excerpt: Changing Faunal Ecology in the Thar Desert - dedicated to the fond memory of Professor Dr. Ishwar Prakash, the legendary rodentologist - is a unique mlange of scientific investigations on diversified ecological subjects pertaining to different organism groups, from as tiny as protozoa to as giant as mammals. Altogether sixteen contributions, including an original, up-to-date and authentic bio-bibliography of Dr. I. Prakash, make this volume an exceptional treatise penned by 24 expert scientist authors many of whom have spent a life in arid ecosystems including the Thar Desert. The book provides a crystal clear proof of the constantly changing behavioural ecology of animals in the Thar Desert which has been under an ever increasing impact of, among several imminent factors, the Indira Gandhi Nahar Pariyojana (IGNP), one of the worlds largest irrigation systems of its type in a xeric environment. The change is discernible not only in structure and distribution of animals but in their resting, feeding, breeding and, as evident in case of parasites, the extent of parasitism as well as pathogenecity. Finally, this book offers the first well documented evidence of immense behavioral transformation in various different animal groups in the Tharp Desert a phenomenon of enormous significance for both conservation management and diversity inventorization activities of its faunal wealth.

Download or read book Coastal Ecosystems of the Tropics Adaptive Management written by Velmurugan Ayyam and published by Springer Nature. This book was released on 2019-10-11 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coastal areas of the tropics are rich in biodiversity, natural resources and place of intensive developmental activities as it provides livelihood to millions of people. At the same time evidences suggest that several unique coastal ecosystems viz., mangroves, wetlands, salt marshes, corals, estuaries, sand dunes and agro-ecosystem are vulnerable to natural disasters and events associated with global climate change. In recent times degradation of land, water and genetic erosion besides threat to native flora and fauna have been increasing due to unsustainable developmental activities. Therefore, a paradigm shift in deriving livelihood through conventional methods, developmental strategies, conservation practices are required for balanced and sustainable growth of the coastal areas. This publication strives to cover the status of different natural resources of the coastal region, various aspects of degradation process, production need and restorative methods besides new technological options and its socio-economic implications with case examples. Special focus is given to bring out the scope and potential of mangrove based farming, integrated and organic farming and its value addition besides the role of coastal vegetations as bioshield in protecting these regions from sea erosion, cyclones and tsunami. As the tropical coastal areas are vulnerable to climate change events, this book also covers the recent weather pattern, impacts of climate change and climate resilient technologies besides intuitional linkages and policy framework aimed at balancing development and environmental concerns.

Download or read book Basic Research and Applications of Mycorrhizae written by Gopi K. Podila and published by I. K. International Pvt Ltd. This book was released on 2007 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal research has grown by leaps and bounds in the past few decades. These fungi promise to promote plant growth, maintain plant and soil health, assist in bio-protection against root diseases, encourage production with reduced fertilizer and pesticides, allow for nutrient acquisition, affect soil skeletal structure holding primary soil particles together, are conductive to the formation of microaggregate structures and higher rhizosphere populations, enable symbiosis that alters host water relations, as well as alter root length and architecture. These fungi also help with the re-vegetation of landscapes, golf courses or contaminated soils. They assist with the biological hardening of tissue culture raised plants, postpone leaf dehydration, draught responses, osmo-protecting enzymes and enhance P acquisition. AM symbiosis could conceivably affect any of these steps. AMF should be considered as an alternative to costly soil disinfection. The mechanisms by which fungi induce resistance in their hosts and enhance disease resistance need critical evaluation and examination. Editors see this volume as a tremendously valuable collection of specialized up-date chapters describing the most sophisticated and modern protocols in mycorrhizal research, thoroughly explained and synthesized.

Download or read book Biofuels Solar and Wind as Renewable Energy Systems written by D. Pimentel and published by Springer Science & Business Media. This book was released on 2008-07-22 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.

Download or read book A Handbook of Tropical Soil Biology written by Fatima M. S. Moreira and published by Routledge. This book was released on 2012-05-04 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity Project, executed by the Tropical Soil Biology and Fertility (TSBF) Institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity and current land uses in terrestrial natural, semi-natural and agroecosystems in tropical forests and at forest margins. The aim is to assess soil biodiversity against current and historic land use practices both at plot and landscape scales and, further, to identify opportunities for improved sustainable land management through the introduction, management or remediation of soil biota, thus reducing the need for external inputs such as fertilizers and pesticides. The book also contains extensive advice on the handling of specimens and the allocation of organisms to strain or functional group type. Published with TSBF-CIAT, CTA, UNEP and GEF
