Eco-Restoration of Polluted Environment
The book Eco-Restoration of the Polluted Environment: A Biological Perspective explores recent advances in biological strategies for the remediation of polluted environments, including soil, water, and air. It covers bioremediation of heavy metals, radioactive waste, and waste gases, which are believed to be bottleneck problems for researchers working in this field. The book contains separate chapters on genetic engineering technology for enhancement of the bioremediation potential of bioresources and the role of biosurfactants, enzymes, and exo-polysaccharides for bioremediation of polluted environments, along with basic aspects of eco-restoration by microorganisms. It summarizes the signif...
Systematics and the Origin of Species
In December 2004, the National Academy of Sciences sponsored a colloquium on "Systematics and the Origin of Species" to celebrate Ernst Mayr's 100th anniversary and to explore current knowledge concerning the origin of species. In 1942, Ernst Mayr, one of the twentieth century's greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. Mayr formulated the transition from Linnaeus's static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In addition to a preceding essay by Edward O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of "species," and genomic approaches for understanding diversity and speciation.
Global Implications of the Nitrogen Cycle
Nitrogen constitutes 78% of the Earth’s atmosphere and inevitably occupies a predominant role in marine and terrestrial nutrient biogeochemistry and the global climate. Callous human activities, like the excessive industrial nitrogen fixation and the incessant burning of fossil fuels, have caused a massive acceleration of the nitrogen cycle, which has, in turn, led to an increasing trend in eutrophication, smog formation, acid rain, and emission of nitrous oxide, which is a potent greenhouse gas, 300 times more powerful in warming the Earth’s atmosphere than carbon dioxide. This book comprehensively reviews the biotransformation of nitrogen, its ecological significance and the consequences of human interference. It will appeal to environmentalists, ecologists, marine biologists, and microbiologists worldwide, and will serve as a valuable guide to graduates, post-graduates, research scholars, scientists, and professors.
Antarctic Terrestrial Microbiology
This book brings together many of the world’s leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils represent one of the most extreme environments on Earth. Once thought to be largely sterile, it is now known that these diverse and often specialized extreme habitats harbor a very wide range of different microorganisms. Antarctic soil communities are relatively simple, but not unsophisticated. Recent phylogenetic and microscopic studies have demonstrated that these communities have well established trophic structuring and play a significant role in nutrient cycling in these cold and often dry desert ecosystems. They are surprisingly responsive to change and potentially sensitive to climatic perturbation. Antarctic terrestrial soils also harbor specialized ‘refuge’habitats, where microbial communities develop under (and within) translucent rocks. These cryptic habitats offer unique models for understanding the physical and biological ‘drivers’ of community development, function and evolution.
The Carbon Age
What do bubbles in a soft drink, a bullet-proof vest, a plastic chair, and our DNA have in common? Carbon. It is, and forever has been, the ubiquitous architect of life and civilization, forming the chemical backbone of every living creature. And yet, when we hear the word today, it is more often than not in a crisis situation: carbon dioxide emissions are destroying the ozone layer and warming the planet; the volatile Middle East explodes atop its stores of hydrocarbons; carbohydrates threaten obesity and diabetics. Carbon, thus, sustains us and threatens us in equal measure, Eric Roston illuminates this essential element in all its forms, cleverly recreating the intricate carbon cycle on t...
