Geology And Plant Life

Before any other influences began to fashion life and its lavish diversity, geological events created the initial environments--both physical and chemical--for the evolutionary drama that followed. Drawing on case histories from around the world, Arthur Kruckeberg demonstrates the role of landforms and rock types in producing the unique geographical distributions of plants and in stimulating evolutionary diversification. His examples range throughout the rich and heterogeneous tapestry of the earth's surface: the dramatic variations of mountainous topography, the undulating ground and crevices of level limestone karst, and the subtle realm of sand dunes. He describes the ongoing evolutionary consequences of the geology-plant interface and the often underestimated role of geology in shaping climate. Kruckeberg explores the fundamental connection between plants and geology, including the historical roots of geobotany, the reciprocal relations between geology and other environmental influences, geomorphology and its connection with plant life, lithology as a potent selective agent for plants, and the physical and biological influences of soils. Special emphasis is given to the responses of plants to exceptional rock types and their soils--serpentines, limestones, and other azonal (exceptional) substrates. Edaphic ecology, especially of serpentines, has been his specialty for years. Kruckeberg's research fills a significant gap in the field of environmental science by connecting the conventionally separated disciplines of the physical and biological sciences. Geology and Plant Life is the result of more than forty years of research into the question of why certain plants grow on certain soils and certain terrain structures, and what happens when this relationship is disrupted by human agents. It will be useful to a wide spectrum of professionals in the natural sciences: plant ecologists, paleobiologists, climatologists, soil scientists, geologists, geographers, and conservation scientists, as well as serious amateurs in natural history.

Published in 1931 for non-specialist readers, this engaging book explains what plant fossils can tell us about prehistoric times.

Carnivorous pitcher plants, pygmy conifers, and the Tiburon jewel flower, restricted to a small patch of serpentine soil on Tiburon Peninsula in Marin County, are just a few of California's many amazing endemic plants—species that are unique to particular locales. California boasts an abundance of endemic plants precisely because it also boasts the richest geologic diversity of any place in North America, perhaps in the world. In lively prose, Arthur Kruckeberg gives a geologic travelogue of California's unusual soils and land forms and their associated plants—including serpentines, carbonate rocks, salt marshes, salt flats, and vernal pools—demonstrating along the way how geology shapes plant life. Adding a fascinating chapter to the story of California's remarkable biodiversity, this accessible book also draws our attention to the pressing need for conservation of the state's many rare and fascinating plants and habitats. *148 outstanding, accurate photographs, more than 100 incolor, illustrate California's diverse flora *Covers a wide range of locations including the Channel Islands, the Central Valley, wetlands, bristlecone pine forests, and bogs and fens *Provides selected trip itineraries for viewing the state's geobotanical wonders *Includes information on human influences on the California landscape from the early Spanish explores through the gold rush and to the present

In this classic work of natural history, John William Dawson traces the development of plant life over millions of years.

This book is a completely revised, substantially extended treatment of the physical and biological factors that drive life in high mountains. The book covers the characteristics of alpine plant life, alpine climate and soils, life under snow, stress tolerance, treeline ecology, plant water, carbon, and nutrient relations, plant growth and productivity, developmental processes, and two largely novel chapters on alpine plant reproduction and global change biology. The book explains why the topography driven exposure of plants to dramatic micro-climatic gradients over very short distances causes alpine biodiversity to be particularly robust against climatic change. Geographically, this book draws on examples from all parts of the world, including the tropics. This book is complemented with novel evidence and insight that emerged over the last 17 years of alpine plant research. The number of figures – mostly in color – nearly doubled, with many photographs providing a vivid impression of alpine plant life worldwide. Christian Körner was born in 1949 in Austria, received his academic education at the University of Innsbruck, and was full professor of Botany at the University of Basel from 1989 to 2014. As emeritus Professor he is continuing alpine plant research in the Swiss Alps.

The landscape and vegetation of the Dolomites have characteristics that are very particular. Some 2300 species live here, about a fifth of the flora in Europe as a whole. This book depicts what the plant cover of the Dolomites is composed of, how it was formed, and what future evolution may bring. The data presented is based on the authors’ combined botanical research, which consists of thousands of surveys throughout the entire region of the Dolomites. To explain the vegetation, 106 plant communities are described in detailed datasheets. Biological, geological, climatic and physical-chemical parameters are given for each plant community, including a description of the habitat, the indicator species, the floristic composition, distribution, conservation, and alteration risks, as well as a distribution map and a photo of the association. The associations are grouped into habitats, such as the human habitat, natural forests and meadows on the valley floor, the coniferous forest belt, screes, alpine vegetation on granite, porphyry, and volcanic rock, as well as on dolomite and limestones. In closing, the authors make a case for using the scientific information provided in the book for the conservation of the Dolomites, the heritage of all humanity. Additional in-depth analysis will be presented in the supplementary volumes “Plant Life of the Dolomites: Vegetation Tables” and “Plant Life of the Dolomites: Atlas of Flora.”
