Handbook of Methods in Aquatic Microbial Ecology is the first comprehensive compilation of 85 fundamental methods in modern aquatic microbial ecology. Each method is presented in a detailed, step-by-step format that allows readers to adopt new methods with little difficulty. The methods represent the state of the art, and many have become standard procedures in microbial research and environmental assessment. The book also presents practical advice on how to apply the methods. It will be an indispensable reference for marine and freshwater research laboratories, environmental assessment laboratories, and industrial research labs concerned with microbial measurements in water.

Aquatic microorganisms are tidily related to the carbon cycle in aquatic systems, especially in respect to its accumulation and emission to atmosphere. In one hand, the autotrophs are responsible for the carbon input to the ecosystems and trophic chain. On the other hand, the heterotrophs traditionally play a role in the carbon mineralization and, since microbial loop theory, may play a role to carbon flow through the organisms. However, it is not yet clear how the heterotrophs contribute to carbon retention and emission especially from tropical aquatic ecosystems. Most of the studies evaluating the role of microbes to carbon cycle in inland waters were performed in high latitudes and only a few studies in the tropical area. In the prospective of global changes where the warm tropical lakes and rivers become even warmer, it is important to understand how microorganisms behave and interact with carbon cycle in the Earth region with highest temperature and light availability. This research topic documented microbial responses to natural latitudinal gradients, spatial within and between ecosystems gradients, temporal approaches and temperature and nutrient manipulations in the water and in the sediment.

This book promotes further understanding of the contribution that fungi make to the biogeochemical cycling of elements, the chemical and biological mechanisms involved, and their environmental and biotechnological significance.

This updated and expanded second edition reviews numerous aspects of the marine microbiome and its possible industrial applications. The marine microbiome is the total of microorganisms and viruses in the ocean and seas and in any connected environment, including the seafloor and marine animals and plants. In the first part of the book, diversity, origin and evolution of the marine microorganisms and viruses are discussed. The microbes presented originate from all three domains of life: Bacteria, Archaea, and Eukarya. The second part sheds some light on the different communities: it describes marine habitats and how their inhabitants control biogeochemical cycles. The third part finally examines the microbial ocean as a global system and evaluates methods of utilizing marine microbial resources. Adopting a translational approach, the book connects academic research with industrial applications, making it a fascinating read and valuable resource for microbiologists from both domains.

Hydrogeochemistry of Aquatic Ecosystems Discover the geological foundation of global water supply, focusing on resource conservation and restoration Hydrogeochemistry explores the connections between the geology of a region and the chemical characteristics and quality of its water sources, including such factors as erosion, evaporation, and, increasingly, man-made activities. With the emergence of climate change as a major factor reshaping water quality and availability, the need to understand interactions between hydrochemistry and geology has never been greater. Hydrogeochemistry of Aquatic Ecosystems meets this need by offering foundational knowledge about the hydrochemistry of different types of aquatic systems, the nature of their interactions with various pollutants and geological processes, and the possibilities and dangers of human intervention. With a particular focus on aqueous resource conservation and restoration, this is a vital, timely guide to a potentially life-saving subject. Hydrogeochemistry of Aquatic Ecosystems readers will also find: Detailed treatment of water-sediment interactions, arsenic and fluoride enrichment, sand mining, and many other subjects Coverage throughout of solute acquisition processes, the carbon cycle, and nutrient geochemistry Case studies from Asia and Africa demonstrating both natural and anthropogenic hydrogeochemical interactions Hydrogeochemistry of Aquatic Ecosystems is indispensable for professionals and researchers in environmental science and environmental engineering, as well as scholars and advanced graduate students working on aquatic ecosystems or effects of climate change.
