This book was released on 2013-06-29 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty million years ago, the Arctic Ocean was a warm sea, bounded by lush vegetation of the warm-temperate shores of Scandinavia, Siberia, Alaska and the Northwest Territories. Wind and storms were rare because Atlantic weather systems had not developed but, as today, polar day length added a hostile element to this otherwise tranquil climate. With the aid of scientists from all the countries close to the Arctic Circle, this book describes the palaeontology, the statistical analysis of vegetational features, comparisons with atmospheric, marine, and geological features and some of the first models of plant migration developed from newly constructed databases.

Book excerpt: How do you know what Gods direction is for your life? How can you find and more clearly understand the wondrous plans He has for you? Would you like to uncover the hidden passion thats lying in wait inside of you? In any economygood or baddo you ever fret about bills and money? Do you experience troubling nagging stressful life issues? Have you been skeptical or had a careless attitude about whether dark, evil forces are real or not? Would you like to encounter a fresh and enlightening simplistic perspective concerning this issue and spiritual warfare? Finally, here is an inspiring, modern-day true story of discovery that will give thought-provoking insight and answers to these and other important questions and problematic dilemmas. Author Jack Kovnas does not tell you how to pray as much as he shows you through his own teaching examples of actual prayer events. With deep humility, he candidly reveals how sinfully and shamefully he lived the beginning stages of his Christian lifewithout prayerbut then turned completely around as he uncovered genuine happiness with prayer. Inside this book you will find a declaration by somebody who learned the value of praying and trusting Godwho willingly gave up house and possessions, and then watched in amazement as they returned. This informative prayer-ride journey is a testimony to what God can and will do for any and all of us. As Jack humbly and assuredly attestseven though it is his own true life story, every sincere, caring word on each and every page is not about himit is about you! Trust in the Lord with all thine heart; and lean not upon thine own understanding. In all thy ways acknowledge Him, and He shall direct thy paths. Proverbs 3:5-6 (KJV)
Download or read book The Universe Within written by Neil Shubin and published by Penguin UK. This book was released on 2013-01-08 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Universe Within, Neil Shubin, one of the world's leading experts, reveals to us the extraordinary cosmic and evolutionary adventure of our own bodies. During the past 13.7 billion years (or so) since the Big Bang, our universe has evolved, stars have formed and died and our planet congealed from the matter in space. For aeons, the earth has circled the sun while mountains, seas and entire continents have come and gone. Against this epic backdrop, humanity's place in the cosmos can look tiny and insignificant. But as Neil Shubin shows in this revelatory new book, the one place where universe, solar system and planet merge is inside your body. Shubin shows how the origin of the Moon is tied to our internal body clocks; how the vast amounts of water on Earth and inside all living creatures crossed the deepest stretches of space to us; how strange fluctuations in the orbits within our solar system have led to our irregular ice-ages; and how tiny imbalances in the chaos immediately after the Big Bang can explain why matter exists at all. Delving below the earth's surface and into the frozen Arctic, exploring the smallest atomic structures and the vast reaches of space, Neil Shubin uncovers a sublimely beautiful, almost magical truth: that in every one of us lies the most profound story of all - how we and our world came to be. 'Shubin is not only a distinguished scientist, but a wonderfully lucid and elegant writer; he is an irrepressibly enthusiastic teacher ... a science writer of the first rank', Oliver Sacks Neil Shubin is a palaeontologist in the great tradition of his mentors, Ernst Mayr and Stephen Jay Gould. He has discovered fossils around the world that have changed the way we think about many of the key transitions in evolution and has pioneered a new synthesis of expeditionary palaeontology, developmental genetics and genomics. He trained at Columbia, Harvard and Berkeley and is currently a Professor in the Department of Organismal Biology and Anatomy at the University of Chicago. His previous book is Your Inner Fish: The amazing discovery of our 375-million-year-old ancestor.

Download or read book Mesozoic Biotas of Scandinavia and its Arctic Territories written by B.P. Kear and published by Geological Society of London. This book was released on 2016-06-02 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scandinavia and its Arctic territories of Svalbard and Greenland represent geographical regions with a long history of Mesozoic palaeontology. However the last few decades have witnessed a surge of new discoveries, especially from the famous Triassic and Late Jurassic Lagerstätten of East Greenland and Spitsbergen in the Svalbard Archipelago, together with the Late Cretaceous strata of southern Sweden and UNESCO World Heritage locality at Stevns Klint in Denmark; the latter recording one of the most complete terminal Mesozoic rock successions known globally. Collectively, these deposits encompass the spectrum of Mesozoic biotic evolution from the explosive radiation of marine faunas after the Permian-Triassic extinction and seminal specialization of amniotes for life in the sea, to the Late Triassic–Jurassic domination of the land by dinosaurs and Cretaceous development of modern terrestrial floras and marine ecosystems. This volume authored by leading experts in the field encapsulates key aspects of the latest research, and will provide a benchmark reference for future investigations into the Scandinavian Mesozoic world.

Available in PDF, EPUB and Kindle. Book excerpt: Changing Cold Environments; Implications for Global Climate Change is a comprehensive overview of the changing nature of the physical attributes of Canada's cold environments and the implications of these changes to cold environments on a global scale. The book places particular emphasis on the broader environmental science and sustainability issues that are of increasing concern to all cold regions if present global climate trends continue. Clearly structured throughout, the book focuses on those elements of Canada's cold environments that will be most affected by global climate change – namely, the tundra, sub-arctic and boreal forest regions of northern Canada, and the high mid-latitude mountains of western Canada. Implications are considered for similar environments around the world resulting in a timely text suitable for second and third year undergraduates in the environmental or earth sciences courses.
Download or read book Remnants of Ancient Life written by Dale Greenwalt and published by Princeton University Press. This book was released on 2023-01-17 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: "We usually think of fossils as being composed of rock, the original contents of the organisms lost to time. However, this is changing. Due to new technologies scientists are able to access the ancient biomolecules--the pigments, proteins, chemicals, and DNA--that once performed critical roles in organisms and have been preserved accross millions of years. In this book, Dale Greenwalt introduces readers to the new science of ancient biomolecules and what it tells about the lives of long extinct life. Ancient biomolecules, as we learn, give us a whole new view into the past. After an introductory explanation of what biomolecules are (and are not), each chapter treats an ancient biomolecule and what it can teach us about a long-dead organism and how it may have lived. For example, analysis of preserved pigmentation has improved our understanding of the evolution of camouflage, feathered dinosaurs, and flight. Ancient proteins aid taxonomic identification and determinations of sex. And ancient DNA-perhaps the best-known ancient biomolecule-can shed light on species' ancestry, including our own. Drawing on a wealth of paleontological research, including his own, Greenwalt traces ancient organic material back millions of years. Throughout, he emphasizes the infancy of this science while the book's conclusion looks ahead to its possible future in everything from the search for life on other planets to de-extinction"--
Download or read book Arctic Ecology written by David N. Thomas and published by John Wiley & Sons. This book was released on 2021-01-26 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.
