This fascinating new volume comes complete with color illustrations and features the methodology and main achievements in the emerging field of paleomicrobiology. It’s an area research at the intersection of microbiology and evolution, history and anthropology. New molecular approaches have already provided exciting results, such as confirmation of a single biotype of Yersinia pestis as the cause of historical plague pandemics. An absorbing read for scientists in related fields.




Paleomicrobiology of Humans


Book Description

Only recently was it determined that two of the world's most devastating plagues, the plague of Justinian and the medieval Black Death, were caused by distinct strains of the same pathogen. Use of paleomicrobiological techniques led to this discovery. This work is just one example of the historical mysteries that this emerging field has helped to clarify. Others, such as when tuberculosis began to afflict humans, the role of lice in plague pandemics, and the history of smallpox, are explored and further illuminated in Paleomicrobiology of Humans. Led by editors Michel Drancourt and Didier Raoult, the book's expert contributors address larger issues using paleomicrobiology. These include the recognition of human remains associated with epidemic outbreaks, identification of the graves of disasters, and the discovery of demographic structures that reveal the presence of an epidemic moment. In addition, the book reviews the technical approaches and controversies associated with recovering and sequencing very old DNA and surveys modern human diseases that have ancient roots. Essentially, paleomicrobiologists aim to identify past epidemics at the crossroads of different specialties, including anthropology, medicine, molecular biology, and microbiology. Thus, this book is of great interest not only to microbiologists but to medical historians and anthropologists as well. Paleomicrobiology of Humans is the first comprehensive book to examine so many aspects of this new, multidisciplinary, scientific field.




Fossil and Recent Biofilms


Book Description

This textbook on biofilms combines knowledge on sub-aquatic and sub-aerial biofilms and their products (stromatolites, oolites, ore, petroleum and gas deposits). It describes how formation and degradation of minerals and rocks is achieved through biofilm formation on and in sediments, soils and rocks. Methods of study, examples of Precambrian biofilms of an early Earth as well as the most recent examples of desert rock biofilms are treated in this integrative book on biofilms, microbial mats and stromatolites.




Geomicrobiology: Molecular and Environmental Perspective


Book Description

The interaction of microorganisms with geological activities results in processes influencing development of the Earth’s geo- and biospheres. In assessing these microbial functions, scientists have explored short- and longterm geological changes attributed to microorganisms and developed new approaches to evaluate the physiology of microbes including microbial interaction with the geological environment. As the field of geomicrobiology developed, it has become highly interdisciplinary and this book provides a review of the recent developments in a cross section of topics including origin of life, microbial-mineral interactions and microbial processes functioning in marine as well as terrestrial environments. A major component of this book addresses molecular techniques to evaluate microbial evolution and assess relationships of microbes in complex, natural c- munities. Recent developments in so-called ‘omics’ technologies, including (meta) genomics and (meta)proteomics, and isotope labeling methods allow new insights into the function of microbial community members and their possible geological impact. While this book summarizes current knowledge in various areas, it also reveals unresolved questions that require future investigations. Information in these chapters enhances our fundamental knowledge of geomicrobiology that contributes to the exploitation of microbial functions in mineral and environmental biotechn- ogy applications. It is our hope that this book will stimulate interest in the general field of geomicrobiology and encourage others to explore microbial processes as applied to the Earth.




Micropaleontology


Book Description

This book will help readers learn the basic skills needed to study microfossils especially those without a formal background in paleontology. It details key principles, explains how to identify different groups of microfossils, and provides insight into their potential applications in solving geologic problems. Basic principles are addressed with examples that explore the strengths and limitations of microfossils and their geological records. This overview provides an understanding of taphonomy and quality of the fossil records, biomineralization and biogeochemistry, taxonomy, concepts of species, and basic concepts of ecology. Readers learn about the major groups of microfossils, including their morphology, ecology, and geologic history. Coverage includes: foraminifera, ostracoda, coccolithophores, pteropods, radiolaria, diatoms, silicoflagellates, conodonts, dinoflagellates, acritarch, and spores and pollens. In this coverage, marine microfossils, and particularly foraminifera, are discussed in more detail compared with the other groups as they continue to play a major role in most scientific investigations. Among the various tracers of earth history, microfossils provide the most diverse kinds of information to earth scientists. This richly illustrated volume will help students and professionals understand microfossils, and provide insight on how to work with them to better understand evolution of life, and age and the paleoenvironment of sedimentary strata.

Their World: A Diversity of Microbial Environments


Book Description

This volume summarizes recent advances in environmental microbiology by providing fascinating insights into the diversity of microbial life that exists on our planet. The first two chapters present theoretical perspectives that help to consolidate our understanding of evolution as an adaptive process by which the niche and habitat of each species develop in a manner that interconnects individual components of an ecosystem. This results in communities that function by simultaneously coordinating their metabolic and physiologic actions. The third contribution addresses the fossil record of microorganisms, and the subsequent chapters then introduce the microbial life that currently exists in various terrestrial and aquatic ecosystems. Coverage of the geosphere addresses endolithic organisms, life in caves and the deep continental biosphere, including how subsurface microbial life may impact spent nuclear fuel repositories. The discussion of the hydrosphere includes hypersaline environments and arctic food chains. By better understanding examples from the micro biosphere, we can elucidate the many ways in which the niches of different species, both large and small, interconnect within the overlapping habitats of this world, which is governed by its microorganisms.




Links Between Geological Processes, Microbial Activities & Evolution of Life


Book Description

Microbial systems in extreme environments and in the deep biosphere may be analogous to potential life on other planetary bodies and hence may be used to investigate the possibilities of extraterrestrial life. This book examines the mode and nature of links between geological processes and microbial activities and their significance for the origin and evolution of life on the Earth and possibly on other planets. This is a truly interdisciplinary science with societal relevance.




Women in Microbiology


Book Description

Many girls want to become scientists when they grow up, just like many boys do. But for these girls, the struggle to do what they love and to be treated with respect has been much harder because of the discrimination and bias in our society. In Women in Microbiology, we meet women who, despite these obstacles and against tough odds, have become scientific leaders and revered mentors. The women profiled in this collection range from historic figures like Alice Catherine Evans and Ruth Ella Moore to modern heroes like Michele Swanson and Katrina Forest. What binds all of these remarkable women are a passion for their work, a zest for life, a warm devotion to mentoring others—especially younger women—and a sense of justice and fairness that they are willing to fight tirelessly to obtain. Each story is unique, but each woman featured in Women in Microbiology has done so much to expand our knowledge of the natural world while also making it easier for the next generation of scientists to work collaboratively and in an atmosphere where people are judged by their intellect, imagination, skill, and commitment to service regardless of gender or race. Women in Microbiology is a wonderful collection of stories that will inspire everyone, but especially young women and men who are wondering how to find their way in the working world. Some of the names are familiar and some are lesser known, but all of the stories arouse a sense of excitement, driven by tales of new, important scientific insights, stories of overcoming adversity and breaking boundaries, and the inclusion of personal tips and advice from successful careers. These stories are proof that a person can live a balanced and passionate life in science that is rich and rewarding.




Early Life on Earth


Book Description

When did life first appear on Earth and what form did it take? The answer to this intriguing and fundamentally important question lies somewhere within the early Archean rock record. The young Earth was, however, a very different place to that we know today and numerous pitfalls await our interpretation of these most ancient rocks. The first half of this practical guide equips the reader with the background knowledge to successfully evaluate new potentially biological finds from the Archean rock record. Successive steps are covered, from locating promising samples in the field, through standard petrography and evaluation of antiquity and biogenicity criteria, to the latest state of the art geochemical techniques. The second half of the guide uniquely brings together all the materials that have been claimed to comprise the earliest fossil record into an easily accessible, fully illustrated format. This will be a handbook that every Archean geologist, palaeobiologist and astrobiologist will wish to have in their backpack or on their lab-bench.
