Biodiversity And Earth History

This uniquely interdisciplinary textbook explores the exciting and complex relationship between Earth’s geological history and the biodiversity of life. Its innovative design provides a seamless learning experience, clarifying major concepts step by step with detailed textual explanations complemented by detailed figures, diagrams and vibrant pictures. Thanks to its layout, the respective concepts can be studied individually, as part of the broader framework of each chapter, or as they relate to the book as a whole. It provides in-depth coverage of: - Earth’s formation and subsequent geological history, including patterns of climate change and atmospheric evolution; - The early stages of life, from microbial ‘primordial soup’ theories to the fossil record’s most valuable contributions; - Mechanisms of mutual influence between living organisms and the environment: how life changed Earth’s history whilst, at the same time, environmental pressures continue to shape the evolution of species; - Basic ideas in biodiversity studies: species concepts, measurement techniques, and global distribution patterns; - Biological systematics, from their historical origins in Greek philosophy and Biblical stories to Darwinian evolution by natural selection, and to phylogenetics based on cutting-edge molecular techniques. This book’s four major sections offer a fresh cross-disciplinary overview of biodiversity and the Earth’s history. Among many other concepts, they reveal the massive diversity of eukaryotes, explain the geological processes behind fossilisation, and provide an eye-opening account of the relatively short period of human evolution in the context of Earth’s 4.6 billion-year history. Employing a combination of proven didactic tools, the book is simultaneously a reading reference, illustrated guide, and encyclopaedia of organismal biology and geology. It is aimed at school- and university-level students, as well as members of the public fascinated by the intricate interrelationship of living organisms and their environment.

This publication gives a broad ecological overview of current condition in the three main parts of the biosphere, the seas, the land and inland waters. It also provides an historical context, from the origin of life on the planet onward. This has been done to demonstrate the long history of life on earth and to emphasise the brevity of human existence. The first part of the book includes a discussion of the components of biodiversity and an account of the expansion of this diversity through geological time and the pattern of distribution on the planet. The second part covers features of human impacts on the environment and the uses currently made of biodiversity. The main lesson drawn is that while life itself has remarkable tenacity, the tenure on earth of individual species has always been a strictly limited one. The environment of any species has two main roles: to provide the essential materials for growth and reproduction of the species and to remove or transform its waste products. A failure of either of these two will have an adverse or catastrophic impact on the species concerned. Ecosystems and the biosphere continue to function because the relentless pressure of natural selection has meant that organisms have evolved that thrive on the waste products of other organisms. This is considered in the book to be the function of biological diversity. A large number of tables and maps are presented in this publication, including a table on biodiversity at country level. This book has a companion volume, 'Life Counts'.

Human activity has irreversibly changed the natural environment. But the news isn't all bad. It's accepted wisdom today that human beings have permanently damaged the natural world, causing extinction, deforestation, pollution, and of course climate change. But in Inheritors of the Earth, biologist Chris Thomas shows that this obscures a more hopeful truth -- we're also helping nature grow and change. Human cities and mass agriculture have created new places for enterprising animals and plants to live, and our activities have stimulated evolutionary change in virtually every population of living species. Most remarkably, Thomas shows, humans may well have raised the rate at which new species are formed to the highest level in the history of our planet. Drawing on the success stories of diverse species, from the ochre-colored comma butterfly to the New Zealand pukeko, Thomas overturns the accepted story of declining biodiversity on Earth. In so doing, he questions why we resist new forms of life, and why we see ourselves as unnatural. Ultimately, he suggests that if life on Earth can recover from the asteroid that killed off the dinosaurs, it can survive the onslaughts of the technological age. This eye-opening book is a profound reexamination of the relationship between humanity and the natural world.

In the past thirty years biodiversity has become one of the central organizing principles through which we understand the nonhuman environment. Its deceptively simple definition as the variation among living organisms masks its status as a hotly contested term both within the sciences and more broadly. In Eden’s Endemics, Elizabeth Callaway looks to cultural objects—novels, memoirs, databases, visualizations, and poetry— that depict many species at once to consider the question of how we narrate organisms in their multiplicity. Touching on topics ranging from seed banks to science fiction to bird-watching, Callaway argues that there is no set, generally accepted way to measure biodiversity. Westerners tend to conceptualize it according to one or more of an array of tropes rooted in colonial history such as the Lost Eden, Noah’s Ark, and Tree-of-Life imagery. These conceptualizations affect what kinds of biodiversities are prioritized for protection. While using biodiversity as a way to talk about the world aims to highlight what is most valued in nature, it can produce narratives that reinforce certain power differentials—with real-life consequences for conservation projects. Thus the choices made when portraying biodiversity impact what is visible, what is visceral, and what is unquestioned common sense about the patterns of life on Earth.

It's a big world out there, and it's populated with millions of different species of plants, animals, and microorganisms! Biodiversity: Explore the Diversity of Life on Earth with Science Activities for Kids introduces middle school readers to the evolution of life on Earth, beginning with the first single-celled organisms that emerged 3.8 billion years ago to the complex multi-celled organisms that exist today and make up the tree of life. Science-minded, hands-on experiments make this a book a fully immersive learning experience!

This book is a comprehensive compendium of conservation information. It aims to provide the first systematic report on the status, distribution, management and utilization of the planet's biological wealth. With extensive use of tables, graphics and maps, it presents standardized and comparable data for 205 countries of the world. The report is divided into three sections: Part I documents diversity at the genetic, species and ecosystem levels, including micro-organisms, species extinctions and rates of habitat loss; Part II covers the benefits and values of biodiversity, focusing on wildlife utilization, domestication and the economic valuation of diversity; Part III reviews the conservation and management of biodiversity at the national and international conventions and institutional and financial support.

This very readable overview of natural history explores the dynamics that have made our planet so rich in biodiversity over time and supported the rise and dominance of our own species. Tracing the arc of evolutionary history, biologist William C. Burger shows that cooperation and symbiosis have played a critical role in the ever increasing complexity of life on earth. Life may have started from the evolution of cooperating organic molecules, which outpaced their noncooperating neighbors. A prime example of symbiosis was the early incorporation of mitochondria into the eukaryotic cell (through a process called “endosymbiosis”). This event gave these cells a powerful new source of energy. Later, cooperation was again key when millions to trillions of individual eukaryotic cells eventually came together to build the unitary structures of large plants and animals. And cooperation between individuals of the same species resulted in complex animal societies, such as ant colonies and bee hives. Turning to our own species, the author argues that our ability to cooperate, along with incessant inter-group conflict, has driven the advancement of cultures, the elaboration of our technologies, and made us the most “invasive” species on the planet. But our very success has now become a huge problem, as our world dominion threatens the future of the biosphere and confronts us with a very uncertain future. Thought-provoking and full of fascinating detail, this eloquently told story of life on earth and our place within it presents a grand perspective and raises many important questions.

The current extinction crisis is of human making, and any favorable resolution of that biodiversity crisis-among the most dire in the 4-billion-year history of Earth-will have to be initiated by mankind. Little time remains for the public, corporations, and governments to awaken to the magnitude of what is at stake. This book aims to assist that critical educational mission, synthesizing recent scientific information and ideas about threats to biodiversity in the past, present, and projected future. This is the second volume from the In the Light of Evolution series, based on a series of Arthur M. Sackler colloquia, and designed to promote the evolutionary sciences. Each installment explores evolutionary perspectives on a particular biological topic that is scientifically intriguing but also has special relevance to contemporary societal issues or challenges. Individually and collectively, the ILE series aims to interpret phenomena in various areas of biology through the lens of evolution, address some of the most intellectually engaging as well as pragmatically important societal issues of our times, and foster a greater appreciation of evolutionary biology as a consolidating foundation for the life sciences.
