Aquatic Humic Substances
Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.
Dissolved Organic Matter in Lacustrine Ecosystems
Concentrations of dissolved organic matter (DOM) in lakes are often an order of magnitude greater than concentrations of particulate organic matter; nevertheless, the biogeochemical analysis of DOM is described in only a few textbooks on limnology (most thoroughly by Wetzel). The orgins of dissolved organic substances are largely photosynthetic; DOM is either autochthonously synthesized by littoral and pelagic flora through secretions and autolysis of cellular contents, or allochthonously generated in terrestrial systems of the drainage basin, composing largely of humic substances refractory to rapid microbial degradation. The role of DOM in lacustrine ecosystems, as energy source and system regulator, however, is still poorly known. The aim of this book is: (1) to present state-of-the-art reviews of the role of dissolved autochthonous and allochthonous organic matter in pelagial and littoral zones; and (2) to focus attention on poorly understood but critical topics and hence to provide direction for future research activity.
Polar Lakes and Rivers
This book provides an overview of the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. It describes each ecosystem type, the remarkable aquatic life that thrives in these extreme habitats, and the similarities and differences between Arctic and Antarctic waters.
Soil Microbiome of the Cold Habitats
This book focuses on cold habitat microbes as a potential source of elite enzymes and secondary metabolites to meet the growing demands of the pharmaceutical, food and biotechnological industries. Microbes living in such extremely cold conditions are reported to produce various biomolecules with potential biotechnological applications. The book overviews recent research trends to discover such important biomolecules and also suggests future research directions to discover such elite novel biomolecules. Salient features: Covers studies on various biotic communities and abiotic components of the soil of terrestrial habitats with a focus on cold habitats Discusses various 'Omic' approaches: metagenomics and meta-transcriptomics Lists adaptation strategies adopted by cold-adapted microbes Highlights various biotechnological and industrially important biomolecules produced by cold-adapted microbes Explores the role of microbial biofilm in the degradation of microplastics in cold habitats
Water, Peace, and War
Now in an updated edition, this pioneering and authoritative study considers the profound impact of the growing global water crunch on international peace and security as well as possible ways to mitigate the crisis. Although water is essential to sustaining life and livelihoods, geostrategist Brahma Chellaney argues that it remains the world’s most underappreciated and undervalued resource. One sobering fact is that the retail price of bottled water is already higher than the international spot price of crude oil. But unlike oil, water has no substitute, raising the specter of water becoming the next flashpoint for conflict. Water war as a concept may not mesh with the conventional constr...
Africa in a Changing Global Environment
Africa is one continent severely affected by the ravaging effects of global environment change yet it is least responsible for this. The continent's rural and urban poor are particularly vulnerable to reduced agricultural production, worsening food security, increased incidence of both flooding and drought, spreading of disease and heightening risk of conflict over scarce land and water resources. As such this timely book consisting of chapters authored by scholars from multidisciplinary backgrounds provides the reader a variety of contexts from which to understand the impacts of global environmental change and how affected African communities are adapting an mitigating the scourge. In addition it discusses different models for mitigation and adaptation applicable to local contexts.
Functions of Natural Organic Matter in Changing Environment
Functions of Natural Organic Matter in Changing Environment presents contributions from the 16th Meeting of the International Humic Substances Society (IHSS 16) held in Hangzhou, China on September 9-14, 2012. It provides a comprehensive and updated research advance in the field of characterization, function, application of humic substances (HS) and natural organic matter (NOM) in environment, agriculture, and industry. A broad range of topics are covered: i) formation, structure and characteristics of HS and NOM; ii) HS/NOM and carbon sequestration; iii) HS/NOM and biogeochemical cycling of nutrients; iv) HS/NOM and the environmental processes of toxic elements and anthropogenic organics; v...
