Such a study is to structural botany what dynamical geology is to structural geol ogy. Just as modern geologists interpret the structure of the rocks by seeking to find how and under what conditions similar rocks are formed today, so ecologists seek to study those plant structures which are changing at the present time, and thus to throw light on the origin of plant structures themselves.

DOWNLOAD EBOOK →These investigations identify and clarify some basic assumptions and methodological principles involved in ecological explanations of plant associations. How are plants geographically distributed into characteristic groups? What are the basic conditions that organize groups of interspecific plant populations that are characteristic of particular kinds of habitats? Answers to these questions concerning the geographical distribution of plants in late 19th century European plant geography and early 20th century American plant ecology can be distinguished according to differing logical assumptions concerning the habitats of plant associations. Through an analysis of several significant case studies in the early history of plant ecology, Konopka distinguishes a logic of habitats that conceives of plant associations in an analogy to individual organisms with a logic that conceives of plant associations in a reciprocal relation to habitat physiography. He argues that a phenomenological conception of the logical attributes of habitats can philosophically complement the physiographic tradition in early plant ecology and provide an attractive alternative to standard reductionism and holism debates that persist today. This wide ranging and original analysis will be valuable for readers interested in the history and philosophy of ecology.

DOWNLOAD EBOOK →Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. Advances understanding of natural disturbances by combining geophysical and ecological processes Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition

DOWNLOAD EBOOK →The rise of American geography as a distinctive science in the United States straddles the 19th and 20th centuries, extending from the post-Civil war period to 1970. American Geography and Geographers: Toward Geographic Science is the first book to thoroughly and richly explicate this history. Its author, Geoffrey J. Martin, the foremost historian on the subject and official archivist of the Association of American Geographers, amassed a wealth of primary sources from archives worldwide, which enable him to chart the evolution of American geography with unprecedented detail and context. From the initial influence of the German school to the emergence of Geography as a unique discipline in American universities and thereafter, Martin clarifies the what, how and when of each advancement. Expansive discussion of the arguments made, controversies ignited and research voyages move hand in hand with the principals who originated and animated them: Davis, Jefferson, Huntington, Bowman, Johnson, Sauer, Hartshorne, and many more. From their grasp of local, regional, global and cultural phenomena, geographers also played pivotal roles in world historical events, including the two world wars and their treaties, as the US became the dominant global power. American Geography and Geographers: Toward Geographical Science is a conclusive study of the birth and maturation of the science. It will be of interest to geographers, teachers and students of geography, and all those compelled by the story of American Geography and those who founded and developed it.

DOWNLOAD EBOOK →The two volumes of this handbook provide a comprehensive account of the emerging and vibrant science of the ecological restoration of both habitats and species. Ecological restoration aims to achieve complete structural and functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, reconstruction or re-creation is also included. Restoration in Practice provides details of state-of-the-art restoration practice in a range of biomes within terrestrial and aquatic (marine, coastal and freshwater) ecosystems. Policy and legislative issues on all continents are also outlined and discussed. The accompanying volume, Principles of Restoration defines the underlying principles of restoration ecology. The Handbook of Ecological Restoration will be an invaluable resource to anyone concerned with the restoration, rehabilitation, enhancement or creation of habitats in aquatic or terrestrial systems, throughout the world.
