Almost half of all life on earth may exist in the world's forest canopies. They may also play a vital role in maintaining the planet's climate, yet they remain largely unexplored owing to difficulties of access. They are renowned for their great diversity and role in forest functioning, yet there are still great gaps in the understanding of this `last biological frontier'. This seminal book shows how canopy science is now in a position to answer many of the outstanding questions, among which are some of the most pressing environmental issues society is presently facing. It represents a major summary of the current understanding of canopy ecology, and maps a path forward into a greater understanding of tropical forest ecology and management at a time when the very future of this ecosystem is threatened by humanity's actions.

The treetops of the world's forests are where discovery and opportunity abound, however they have been relatively inaccessible until recently. This book represents an authoritative synthesis of data, anecdotes, case studies, observations, and recommendations from researchers and educators who have risked life and limb in their advocacy of the High Frontier. With innovative rope techniques, cranes, walkways, dirigibles, and towers, they finally gained access to the rich biodiversity that lives far above the forest floor and the emerging science of canopy ecology. In this new edition of Forest Canopies, nearly 60 scientists and educators from around the world look at the biodiversity, ecology, evolution, and conservation of forest canopy ecosystems. -Comprehensive literature list -State-of-the-art results and data sets from current field work -Foremost scientists in the field of canopy ecology -Expanded collaboration of researchers and international projects -User-friendly format with sidebars and case studies -Keywords and outlines for each chapter

Forest management is a complex process that now incorporates information obtained from many sources. It is increasingly obvious that the physiological status of the trees in a forest has a dramatic impact on the likely success of any particular management strategy. Indeed, models described in this book that deal with forest productivity and sustainability require physiological information. This information can only be obtained from an understanding of the basic biological mechanisms and processes that contribute to individual tree growth. This valuable book illustrates that physiological ecology is a fundamental element of proficient forest management. Provides essential information relevant to the continuing debate over sustainable forest management Outlines how modern tools for physiological ecology can be used in planning and managing forest ecosystems Reviews the most commonly used forest models and assesses their value and future

Process-based models open the way to useful predictions of the future growth rate of forests and provide a means of assessing the probable effects of variations in climate and management on forest productivity. As such they have the potential to overcome the limitations of conventional forest growth and yield models, which are based on mensuration data and assume that climate and atmospheric CO2 concentrations will be the same in the future as they are now. This book discusses the basic physiological processes that determine the growth of plants, the way they are affected by environmental factors and how we can improve processes that are well-understood such as growth from leaf to stand level and productivity. A theme that runs through the book is integration to show a clear relationship between photosynthesis, respiration, plant nutrient requirements, transpiration, water relations and other factors affecting plant growth that are often looked at separately. This integrated approach will provide the most comprehensive source for process-based modelling, which is valuable to ecologists, plant physiologists, forest planners and environmental scientists. Includes explanations of inherently mathematical models, aided by the use of graphs and diagrams illustrating causal interactions and by examples implemented as Excel spreadsheets Uses a process-based model as a framework for explaining the mechanisms underlying plant growth Integrated approach provides a clear and relatively simple treatment

For decades ecologists, physiologists, tropical biologists and many others in related disciplines have been interested in the structure, function, and inhabitants of the forest canopy. Unfortunately, for nearly as long, this fascinating ecosystem seemed inaccessible. Recently, this situation has greatly improved. Using balloons, ropes, towers and cranes, scientists have begun to penetrate this dense foliage, allowing for a detailed, authoritative account of life in the enchanting world.

Since the publication of the first edition of this book ten years ago, international research into the physiological ecology of plants in the tropics has increased enormously in quantity and quality. This brand new edition brings the story right up to date. New approaches have been developed in remote sensing while at the other end of the scale molecular biology has come on in leaps and bounds, particularly regarding ecological performance of tropical plants, e.g. in understanding the adaptation of resurrection plants to the extreme habitat of inselbergs. In this fully revised and updated second edition the wealth of new information has made it necessary to break large chapters down into smaller ones.

The efficient management of trees and other woody plants can be improved given an understanding of the physiological processes that control growth, the complex environmental factors that influence those processes, and our ability to regulate and maintain environmental conditions that facilitate growth. Emphasizes genetic and environmental interactions that influence woody plant growth Outlines responses of individual trees and tree communities to environmental stress Explores cultural practices useful for efficient management of shade, forest, and fruit trees, woody vines, and shrubs

There is a new emerging interest in the effects of gaps and patches on succession and biodiversity. This innovative volume is a synthesis of studies of plant responses to temporal and spatial heterogeneity, the exploitation of resources from pulses and patches by plants, and their competition with neighbors in the face of this variability. Aboveground, the book focuses upon the nature of canopy patchiness, consequences of this heterogeneity for the light environment, and the mechanisms by which plants respond to and exploit this patchiness. Belowground, the text explores the heterogeneity of soil environments and how root systems obtain nutrients and water in the context of this temporal and spatial variability. As a new reference in an evolving and growing field, this text is sure to be a valuable tool for researchers and advanced students in plant physiology, ecology, agronomy, and forestry alike.

The stability of forest ecosystems is affected by changes of environment conditions, like by increasing temperatures, increasing atmospheric CO2 and decreasing deposition rates of nutrients and acidity. This volume integrates the results of long term interdisciplinary ecosystem research at two forested watersheds in Germany with special emphasis on the biogeochemistry of carbon, dissolved organic matter and mineral elements in response to changing environmental conditions and management. Despite the reduction in acidic deposition, forest ecosystems are still threatened by soil acidification, nutrient depletion and eutrophication and criteria of sustainability are not yet achieved. The results highlight the complex interactions between vegetation, animals and soils in terrestrial ecosystems that are triggered by changes in environmental conditions.

Lianas are woody vines that were the focus of intense study byearly ecologists, such as Darwin, who devoted an entire book to thenatural history of climbing plants. Over the past quartercentury, there has been a resurgence in the study of lianas, andliana are again recognized as important components of many forests,particularly in the tropics. The increasing amount ofresearch on lianas has resulted in a fundamentally deeperunderstanding of liana ecology, evolution, and life-history, aswell as the myriad roles lianas play in forest dynamics andfunctioning. This book provides insight into the ecology and evolution oflianas, their anatomy, physiology, and natural history, theirglobal abundance and distribution, and their wide-ranging effectson the myriad organisms that inhabit tropical and temperateforests.
