A Revision of Fossil Sequoia and Taxodium in Western North America Based on the Recent Discovery of Metasequoia


Book Description

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.










The Geobiology and Ecology of Metasequoia


Book Description

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.










The Origin of Species by DNA Coding


Book Description

Who are we? Where are we from? These questions have troubled people for centuries. The textbooks have long taught us that human beings evolved from anthropoid apes. Today, a new science, molecular anthropology, tells us this: 7 billion human beings in the world share a common grand, grand…father, the Y-chromosome Adam, and share a common grand, grand…mother, the Mitochondrial Eve. After reading information in this book, you will be convinced that human beings could not be the result of evolution, sudden mutation, or in any way related to the anthropoid apes.




Cenozoic Plants and Climates of the Arctic


Book Description

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.

Geobotany


Book Description

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.
