Download or read book A Revision of Fossil Sequoia and Taxodium in Western North America Based on the Recent Discovery of Metasequoia written by Ralph Works Chaney and published by American Philosophical Society. This book was released on 1951 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recently discovered redwood of China, "Metasequoia glyptostroboides" Hu & Cheng, shows close relationship to two North American trees, the coast redwood, "Sequoia sempervirens" Endlicher of the western U.S., & the swamp cypress, "Taxodium distichum" Richard of the Southeastern U.S. Foliage & cones of these living trees provide characters by which the three genera may be readily distinguished. But for nearly a century there has been confusion in the recognition of fossil specimens. The author is now able to distinguish the fossil foliage & cones of all three genera, & to assign to Metasequoia many specimens which have previously been identified as Sequoia & Taxodium. Illustrations.

This book was released on 2005-03-30 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

Download or read book Cenozoic Plants and Climates of the Arctic written by Michael C. Boulter and published by Springer Science & Business Media. 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.
Download or read book Geobotany written by Robert Romans and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume were presented at the Geobotany Conference held at Bowling Green State University, Bowling Green, Ohio, on 21 February 1976. Though such diverse topics as anthropology and paleobotany are covered, all papers utilized the concept of geobotany as a unifying theme. Nearly a decade ago, the first in this series of geobotany conferences was organized on this campus by Dr. Jane Forsyth of the Department of Geology. After considerable growth, culminating in an International Geobotany Conference at the University of Tennessee in 1973, it was decided to again organize a regional geobotany meeting. The melange of papers in this volume are products of that meeting. Geobotany, by definition, is an interdiscip1inarian approach to interpretational problems involving such investigators as geologists and botanists, archaeologists and stratigraphers, ecologists and pa1yno1ogists. Interaction among these individuals is necessary for the satisfactory solution of a problem. Each can provide invaluable assistance to the other. The purpose of the meeting in Bowling Green was to provide a forum for the exchange of ideas and information. Sponsors of the conference include the Department of Biological Sciences, the Department of Geology, the Environmental Studies Center, the College of Arts and Sciences, and the Graduate School. All of the sponsors are academic or administrative units of Bowling Green State University and each played an important role in the success of the conference.

Download or read book Late Cainozoic Floras of Iceland written by Thomas Denk and published by Springer Science & Business Media. This book was released on 2011-03-28 with total page 863 pages. Available in PDF, EPUB and Kindle. Book excerpt: Being the only place in the northern North Atlantic yielding late Cainozoic terrestrial sediments rich in plant fossils, Iceland provides a unique archive for vegetation and climate development in this region. This book includes the complete plant fossil record from Iceland spanning the past 15 million years. Eleven sedimentary rock formations containing over 320 plant taxa are described. For each flora, palaeoecology and floristic affinities within the Northern Hemisphere are established. The exceptional fossil record allows a deeper understanding of the role of the “North Atlantic Land Bridge” for intercontinental plant migration and of the Gulf Stream-North Atlantic Current system for regional climatic evolution. ’Iceland sits as a “fossil trap” on one of the most interesting biogeographic exchange routes on the planet - the North Atlantic. The fossil floras of Iceland document both local vegetational response to global climate change, and more importantly, help to document the nature of biotic migration across the North Atlantic in the last 15 million years. In this state-of-the-art volume, the authors place sequential floras in their paleogeographic, paleoclimatic and geologic context, and extract a detailed history of biotic response to the dynamics of physical change.’ Bruce H. Tiffney, University of California, Santa Barbara ’This beautifully-illustrated monograph of the macro- and microfloras from the late Cenozoic of Iceland is a worthy successor to Oswald Heer’s “Flora fossilis arctica”. Its broad scope makes it a must for all scientists interested in climatic change and palaeobiogeography in the North Atlantic region. It will remain a classic for years to come.’ David K. Ferguson, University of Vienna

Book excerpt: The epic story of the planet’s oldest trees and the making of the modern world Humans have always revered long-lived trees. But as historian Jared Farmer reveals in Elderflora, our veneration took a modern turn in the eighteenth century, when naturalists embarked on a quest to locate and precisely date the oldest living things on earth. The new science of tree time prompted travelers to visit ancient specimens and conservationists to protect sacred groves. Exploitation accompanied sanctification, as old-growth forests succumbed to imperial expansion and the industrial revolution. Taking us from Lebanon to New Zealand to California, Farmer surveys the complex history of the world’s oldest trees, including voices of Indigenous peoples, religious figures, and contemporary scientists who study elderflora in crisis. In a changing climate, a long future is still possible, Farmer shows, but only if we give care to young things that might grow old.

Book excerpt: This book provides an overview, research compendium and an introduction to the science of molecular paleontology, including literature overview for non-geochemists. Analytical methods employed are included as a part of each chapter that underpin this branch of paleontology and indeed geochemistry. The primary usefulness of this volume is for organic geochemists, molecular palaeontologists, and molecular archeologists. Researchers, graduate students and academics interested in astrobiology from a paleontological perspective may also find this to be valuable.
