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.

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.

In this classic work of natural history, John William Dawson traces the development of plant life over millions of years. With exquisite detail and insight, he describes the fascinating evolution of different species and their interactions with the changing environment. This book is a must-read for anyone interested in botany, ecology, or the history of life on earth.

Questions as to the origin and history of life are not at the present time answered by mere philosophical speculation and poetical imagining. Such solutions of these questions as science can profess to have obtained are based on vast accumulations of facts respecting the remains of animals and plants preserved in the rocky beds of the earth’s crust, which have been successively accumulated in the course of its long geological history. These facts undoubtedly afford the means of attaining to very certain conclusions on many points relating to the history of life on the earth. But, on the other hand, they have furnished the material for hypotheses which, though confidently affirmed to be indisputable, have no real foundation in nature, and are indirectly subversive of some of the most sacred beliefs of mankind. In these circumstances it is most desirable that those who are not specialists in such matters should be in a position to judge for themselves; and it does not appear impossible in the actual state of knowledge, to present, in terms intelligible to the general reader, such a view of the ascertained sequence of the forms of life as may serve at once to give exalted and elevating views of the great plan of creation, and to prevent the deceptions of pseudo-scientists from doing their evil work. Difficulties, no doubt, attend the attempt. They arise from the number and variety of the facts, from the uncertainties attending many important points, from the new views constantly opening up in the progress of discovery, and from the difficulty of presenting in an intelligible form the preliminary data in biology and geology necessary for the understanding of the questions in hand. In order, as far as possible, to obviate these difficulties, the plan adopted in this work has been to note the first known appearance of each leading type of life, and to follow its progress down to the present time or until it became extinct. This method is at least natural and historical, and has commended itself to the writer as giving a very clear comprehension of the actual state of our knowledge, and as presenting some aspects of the subject which may be novel and suggestive even to those who have studied it most deeply. In selecting examples and illustrations, the writer has endeavoured to avoid, as far as possible, those already familiar to the general reader. He has carefully sought for the latest facts, while rejecting as unproved many things that are confidently asserted; and has endeavoured to avoid all that is irrelevant to the subject in hand, and to abstain from all technical terms not absolutely essential. In a work at once so wide in its scope, so popular in its character, and so limited in its dimensions, a certain amount of hostile criticism on the part of specialists is to be expected, some portion of it perhaps just, other portions arising from narrow prejudices due to limited lines of study. The writer is willing to receive such comments with attention and gratitude, but he would deprecate the misuse of them in the interest of those coteries which are at present engaged in the effort to torture nature into a confession of belief in the doctrines of a materialistic or agnostic philosophy.

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.”
