Lake Pavin

This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Next Generation Sequencing technologies are increasingly revealing that microbial taxa likely to be parasites or symbionts are probably much more prevalent and diverse than previously thought. Every well studied free-living species has parasites; parasites themselves can be parasitized. As a rule of thumb, there is an estimated 4 parasitic species for any given host, and the better a host is studied the more parasites are known to infect it. Therefore, parasites and other symbionts should represent a very large number of species and may far outnumber those with 'free-living' lifestyles. Paradoxically, free-living hosts, which form the bulk of our knowledge of biology, may be a minority! Microbial parasites typically are characterized by their small size, short generation time, and high rates of reproduction, with simple life cycle occurring generally within a single host. They are diverse and ubiquitous in the environment, comprising viruses, prokaryotes and eukaryotes. This Frontiers Research Topic sought to provide a broad overview but concise, comprehensive, well referenced and up-to-date state of the art for everyone involved with microbial parasites in aquatic microbial ecology.

An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996. It was the third International Joint Conference on Limnology and Oceanography which brings together specialists of both environments. Considered to be necessary in Europe, this confrontation of two different aspects of common subjects could produce innovative approaches. The main purpose concerns scientific researches relative to the interfaces between various aquatic environment compartments. The principal treated topics are bioavailability and mobility of substances, influence of biotic and abiotic factors on transfers, and fluxes at the interfaces. It is particularly interesting to note the contribution of Limnologists and Oceanographers on the impact of nutrients and pollutants, and flux quantification of river basin inputs. As well as scientists, this book is also of interest to all engineers and consultants involved in teaching and working in aquatic management, restoration and enhancement.

Freshwater Microbiology: Perspectives of Bacterial Dynamics in Lake Ecosystems provides a comprehensive and systematic analysis of microbial ecology in lakes. It offers basic information on how well the bacterial community composition varies along the spatio-temporal and trophic gradients along with the evaluation of the bioindicator species of bacteria so as to act as a key to predict the trophic status of lake ecosystems. The book helps to identify the factors of potential importance in structuring the bacterial communities in lakes as it delves into the dynamics and diversity of bacterial community composition in relation to various water quality parameters. It helps to identify the possibility of bioremediation plans and devising future policy decisions, with better conservation and management practices. Provides a comprehensive and systematic analysis of microbial ecology Helps to identify the factors of potential importance in structuring the bacterial community composition Gives insight into the bacterial diversity of freshwater lake ecosystems along with their industrial potential Caters to the needs and aspirations of students and professional researchers

This book provides a comprehensive summary of research to date in the field of stable iron isotope geochemistry. Since research began in this field 20 years ago, the field has grown to become one of the major research fields in "non-traditional" stable isotope geochemistry. This book reviews all aspects of the field, from low-temperature to high-temperature processes, biological processes, and cosmochemical processes. It provides a detailed history and state-of-the art summary about analytical methods to determine Fe-isotope ratios and discusses analytical and sample prospects.

Freshwater Mycology: Perspectives of Fungal Dynamics in Freshwater Ecosystems presents chapters from expert contributors around the world. Through the contributed chapters, the contributors explore the perspectives of fungal dynamics in freshwater ecosystems, especially their diversity, distribution, functioning and role, biotransformation and bioprospecting potential, methodical advancements and metagenomic insights. Written with aquatic ecologists in mind, this book provides information on oceanic, estuarine and freshwater ecosystems not currently well understood and identifies new questions and answers about the roles of mycology in aquatic ecosystems. This topic is becoming an increasingly important area to understand due to the increasing global transports of microbes due to climate change and human actions. This is leading to a rapid loss of healthy freshwater ecosystems, the grave problem of antibiotic resistance, and the rarity of qualified mycology taxonomists and molecular systematicians. Includes data from locations not previously or well covered from prior synthesis publications Identifies new information on the roles of mycology in aquatic ecosystems Provides insights into the fungal diversity of freshwater ecosystems, along with their potential roles
