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.

This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments. Special emphasis is given to the biogeochemistry that plays such a central role in the formation of sedimentary sulfides. It will be of interest to scientists in a number of disciplines, including geology, microbiology, chemistry and environmental science. The sulfur system is important to environmental scientists considering the present and future effects of pollution and anoxia. The development of the sulfur system – particularly the characteristics of ocean anoxia over the last 200 Ma – is useful in predicting the future fate of the Earth surface system as well as in understanding the past. The biochemistry and microbiology of the sulfur system are key to understanding microbial ecology and the evolution of life. - First monograph on sedimentary sulfides, covering the ancient and modern sedimentary sulfide systems - Comprehensive, integrating chemistry, microbiology, geology and environmental science - All key references are included and discussed

This is the first general selection from the substantial body of surviving documents about Elizabeth’s navy. It is a companion to The Navy of Edward VI and Mary I (Vol.157 in the NRS Series), where the apparatus serving both volumes was printed, and it complements the other NRS volumes that deal specifically with the Spanish Armada. This collection concentrates (though not exclusively so) on the early years of Elizabeth’s reign when there was no formal war. From 1558-1585 the navy was involved in a number of small-scale campaigns, pursuit of pirates and occasional shows of force. The documents selected emphasize the financial and administrative processes that supported these operations, such as mustering, victualing, demobilisation, and ship maintenance and repair. The fleet varied in size from about 30 to 45 ships during the period and a vast amount of maintenance and repair was required. The main component of the volume is the massively detailed Navy Treasurer's account for 1562-3 which is followed by and collated with the corresponding Exchequer Account. The documents illustrate just how efficiently the dockyards functioned. They were one of the great early Elizabethan achievements.
Most people have heard of pyrite, the brassy yellow mineral sometimes known as fool's gold. Pyrite behaves like stone and shines like metal, and its dual nature makes it a source of both metals and sulfur. Despite being the most common sulfide mineral on the earth's surface, pyrite's bright crystals have attracted the attention of many different cultures, and its nearly identical visual appearance to gold has led to tales of fraud, trickery, and claims of alchemy. Pyrite occupies a unique place in human history: it became an integral part of mining culture in America during the 19th century, and it has a presence in ancient Sumerian texts, Greek philosophy, and medieval poetry, becoming a symbol for anything overvalued. In Pyrite, geochemist and author David Rickard blends basic science and historical narrative to describe the many unique ways pyrite is integral to our world. He explains the basic science of oxidation, showing us why the mineral looks like gold, and inspects death zones of present oceans where pyrite-related hydrogen sulfide destroys oxygen in the waters. Rickard analyzes pyrite's role in manufacturing sulfuric acid and discusses the significant appearance of the mineral in literature, history, and the development of societies. The mineral's influence extends from human evolution and culture, through science and industry, to our understanding of ancient, modern, and future earth environments. Energetic and accessible, Pyrite is the first book to show readers the history and science of a mineral that helped make the modern world.
An accessible exploration of pyrite's influence on human history, culture, and science, revealing how fool's gold has become a universal symbol for everything overvalued.
Sure to become a game-changing guide to the future of good food and healthy landscapes." —Dan Barber, chef and author of The Third Plate Prepare to set aside what you think you know about yourself and microbes. The Hidden Half of Nature reveals why good health—for people and for plants—depends on Earth’s smallest creatures. Restoring life to their barren yard and recovering from a health crisis, David R. Montgomery and Anne Biklé discover astounding parallels between the botanical world and our own bodies. From garden to gut, they show why cultivating beneficial microbiomes holds the key to transforming agriculture and medicine.
Unlike most books on climate change, this one examines the current trends in climate--and predictions for the future--relative to similar events in Earth's history. This history paints a picture of repeated cataclysms in which most life on Earth was lost. However, our planet now hosts a species potentially capable of mitigating, regulating, and/or moderating the factors affecting global climate. According to widely accepted data, we have a narrowing window of time to make the necessary changes before we become just another name on a long list of species wiped out through climate catastrophes. Trexler, a paleontologist in Montana, makes powerful and specific suggestions for how the challenges facing our planet can be lessened or avoided.
Metallic Mineral Resources: The Critical Components for a Sustainable Earth serves the increasing interest in metal resources, especially the critical and strategic metals which are essential commodities for the green energy transition. The opening chapters introduce the heterogeneous distribution of metal resources as well as the industrial use of metals. The main chapters then work systematically through abundant metal systems, scarce critical metal systems, rare critical metal systems, trace critical metal systems, and precious metal systems. The book wraps with a close examination of temporal distribution of mineral resources and an insightful discussion of the future of mineral resources. Researchers and engineers in economic geology and mining and exploration industries will find themselves returning to this key reference for years to come.• Describes how mineable and economic metal concentrations form and are preserved in the Earth's upper crust • Explores how they are discovered by systematic mineral exploration at a variety of scales • Discusses how to educate the public on the scarcity of natural metal resources and the issues concerning the nexus between the energy transition and potential exhaustion of critical metals
This thought-provoking book introduces a way to study ecosystems that is resonant with current thinking in the fields of earth system science, geobiology, and planetology. Instead of organizing the subject around a hierarchical series of entities (e.g. genes, individuals, populations, species, communities, and the biosphere), the book provides an alternative process-based approach and proposes a truly planetary view of ecological science. It demonstrates how the idea of fundamental ecological processes can be developed at the systems level, specifically their involvement in control and feedback mechanisms. This enables the reader to reconsider fundamental ecological processes such as energy flow, guilds, trade-offs, carbon cycling, and photosynthesis, and to put them in a global (and even planetary) context. In so doing, the book places a much stronger emphasis on microorganisms. Since publication of the first edition in 2006, ever growing societal concern about environmental sustainability has ensured that the earth system science/Gaian approach has steadily gained traction. Its integration with ecology is now more important than ever if ecological science is to effectively contribute to the massive problems and future challenges associated with global environmental change. The Fundamental Processes in Ecology is an accessible text for senior undergraduates, graduate student seminar courses, and researchers in the fields of ecology, environmental sustainability, earth system science, evolutionary biology, palaeontology, history of life, astrobiology, planetology, climatology, geology, and physical geography.
This book deals with macro and micro aspects of population change and their inter-face with socio-economic factors and impact. It examines theoretical notions and pursues their empirical manifestations and uses multidisciplinary approaches to population change and diversity. It investigates the organic nature of the relationships between socio-economic factors and population change and the feedback loops that affect socio-economic organisation and behaviour. The book brings together material often scattered in a number of sources and disciplines that helps to understand population change and their socio-economic aspects. In addition to dealing with the more conventional factors in population dynamics in the form of fertility, mortality and migration, the book examines socio-economic forces that influence them. It discusses population evolving attributes that affect population characteristics and social and behaviour and impact on the environment. Further, it deals with social organisation and pathways that lead to different social and economic development and standards of living of diverse populations.

Leaves are all around us—in backyards, cascading from window boxes, even emerging from small cracks in city sidewalks given the slightest glint of sunlight. Perhaps because they are everywhere, it’s easy to overlook the humble leaf, but a close look at them provides one of the most enjoyable ways to connect with the natural world. A lush, incredibly informative tribute to the leaf, Nature’s Fabric offers an introduction to the science of leaves, weaving biology and chemistry with the history of the deep connection we feel with all things growing and green. Leaves come in a staggering variety of textures and shapes: they can be smooth or rough, their edges smooth, lobed, or with tiny teeth. They have adapted to their environments in remarkable, often stunningly beautiful ways—from the leaves of carnivorous plants, which have tiny “trigger hairs” that signal the trap to close, to the impressive defense strategies some leaves have evolved to reduce their consumption. (Recent studies suggest, for example, that some plants can detect chewing vibrations and mobilize potent chemical defenses.) In many cases, we’ve learned from the extraordinary adaptations of leaves, such as the invention of new self-cleaning surfaces inspired by the slippery coating found on leaves. But we owe much more to leaves, and Lee also calls our attention back to the fact that that our very lives—and the lives of all on the planet—depend on them. Not only is foliage is the ultimate source of food for every living thing on land, its capacity to cycle carbon dioxide and oxygen can be considered among evolution’s most important achievements—and one that is critical in mitigating global climate change. Taking readers through major topics like these while not losing sight of the small wonders of nature we see every day—if you’d like to identify a favorite leaf, Lee’s glossary of leaf characteristics means you won’t be left out on a limb—Nature’s Fabric is eminently readable and full of intriguing research, sure to enhance your appreciation for these extraordinary green machines.
This book presents a hypothesis and evidence that organisms promote and ecosystems maximize biodiversity. All species have a net positive effect on their environment, other species, and diversity. The sun is 30% hotter than when life began, but the temperature has been kept moderate by life. Life created high oxygen, the ozone layer, and fertile soil, a diverse, living system. No species evolves in isolation, and most evolution is coevolution. The nature and number of links between species are as important as species number. Eukaryotes coevolve with complex ecosystems of microbes with which they exchange genes. Genomes and intraspecific interactions both act to promote evolution and diversification. Viruses increase diversity of their hosts and cause macroevolutionary transitions. Key Features Life alters the Earth in ways that increase biodiversity All species make their environment better for other species and promote diversity Life created the life-friendly atmosphere, temperature, and soil of today
This book presents a comprehensive overview of the science of the history of life. Paleobiologists bring many analytical tools to bear in interpreting the fossil record and the book introduces the latest techniques, from multivariate investigations of biogeography and biostratigraphy to engineering analysis of dinosaur skulls, and from homeobox genes to cladistics. All the well-known fossil groups are included, including microfossils and invertebrates, but an important feature is the thorough coverage of plants, vertebrates and trace fossils together with discussion of the origins of both life and the metazoans. All key related subjects are introduced, such as systematics, ecology, evolution and development, stratigraphy and their roles in understanding where life came from and how it evolved and diversified. Unique features of the book are the numerous case studies from current research that lead students to the primary literature, analytical and mathematical explanations and tools, together with associated problem sets and practical schedules for instructors and students. New to this edition The text and figures have been updated throughout to reflect current opinion on all aspects New case studies illustrate the chapters, drawn from a broad distribution internationally Chapters on Macroevolution, Form and Function, Mass extinctions, Origin of Life, and Origin of Metazoans have been entirely rewritten to reflect substantial advances in these topics There is a new focus on careers in paleobiology
WINNER OF THE 2018 JOHN BURROUGHS MEDAL FOR OUTSTANDING NATURAL HISTORY WRITING “Both a love song to trees, an exploration of their biology, and a wonderfully philosophical analysis of their role they play in human history and in modern culture.” —Science Friday The author of Sounds Wild and Broken and the Pulitzer Prize finalist The Forest Unseen visits with nature’s most magnificent networkers — trees David Haskell has won acclaim for eloquent writing and deep engagement with the natural world. Now, he brings his powers of observation to the biological networks that surround all species, including humans. Haskell repeatedly visits a dozen trees, exploring connections with people, microbes, fungi, and other plants and animals. He takes us to trees in cities (from Manhattan to Jerusalem), forests (Amazonian, North American, and boreal) and areas on the front lines of environmental change (eroding coastlines, burned mountainsides, and war zones.) In each place he shows how human history, ecology, and well-being are intimately intertwined with the lives of trees. Scientific, lyrical, and contemplative, Haskell reveals the biological connections that underpin all life. In a world beset by barriers, he reminds us that life’s substance and beauty emerge from relationship and interdependence.
The celebrated lower Cambrian Chengjiang biota of Yunnan Province, China, represents one of the most significant ever paleontological discoveries. Deposits of ancient mudstone, about 520 million years old, have yielded a spectacular variety of exquisitely preserved fossils that record the early diversification of animal life. Since the discovery of the first specimens in 1984, many thousands of fossils have been collected, exceptionally preserving not just the shells and carapaces of the animals, but also their soft tissues in fine detail. This special preservation has produced fossils of rare beauty; they are also of outstanding scientific importance as sources of evidence about the origins of animal groups that have sustained global biodiversity to the present day. Much of the scientific documentation of the Chengjiang biota is in Chinese, and the first edition of this book was the first in English to provide fossil enthusiasts with a comprehensive overview of the fauna. The second edition has been fully updated and includes a new chapter on other exceptionally preserved fossils of Cambrian age, exciting new fossil finds from Chengjiang, and a phylogenetic framework for the biota. Displaying some 250 figures of marvelous specimens, this book presents to professional and amateur paleontologists, and all those fascinated by evolutionary biology, the aesthetic and scientific quality of the Chengjiang fossils.

For the first time in paperback and with a new introduction. Discover how and why the government is corrupting scientific research. When Speaker Newt Gingrich greeted Dr. David Lewis in his office overlooking the National Mall, he looked at Dr. Lewis and said: “You know you’re going to be fired for this, don’t you?” “I know,” Dr. Lewis replied, “I just hope to stay out of prison.” Gingrich had just read Dr. Lewis’s commentary in Nature, titled “EPA Science: Casualty of Election Politics.” Three years later, and thirty years after Dr. Lewis began working at EPA, he was back in Washington to receive a Science Achievement Award from Administrator Carol Browner for his second article in Nature. By then, EPA had transferred Dr. Lewis to the University of Georgia to await termination—the Agency’s only scientist to ever be lead author on papers published in Nature and Lancet. The government hires scientists to support its policies; industry hires them to support its business; and universities hire them to bring in grants that are handed out to support government policies and industry practices. Organizations dealing with scientific integrity are designed only to weed out those who commit fraud behind the backs of the institutions where they work. The greatest threat of all is the purposeful corruption of the scientific enterprise by the institutions themselves. The science they create is often only an illusion, designed to deceive; and the scientists they destroy to protect that illusion are often our best. This book is about both, beginning with Dr. Lewis’s experience, and ending with the story of Dr. Andrew Wakefield. This new edition, now for the first time in paperback, features a new introduction by the author.
