Forest Dynamics, Growth and Yield


Book Description

The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.




The Human Age: The World Shaped By Us


Book Description

Winner of the National Outdoor Book Award and the PEN New England Henry David Thoreau Prize. A dazzling, inspiring tour through the ways that humans are working with nature to try to save the planet. With her celebrated blend of scientific insight, clarity, and curiosity, Diane Ackerman explores our human capacity both for destruction and for invention as we shape the future of the planet Earth. Ackerman takes us to the mind-expanding frontiers of science, exploring the fact that the "natural" and the "human" now inescapably depend on one another, drawing from "fields as diverse as evolutionary robotics…nanotechnology, 3-D printing and biomimicry" (New York Times Book Review), with probing intelligence, a clear eye, and an ever-hopeful heart.




Advanced Technology for Design and Fabrication of Composite Materials and Structures


Book Description

The last decade has seen a significant growth in the processing and fabrication of advanced composite materials. This volume contains the up-to-date contributions of those with working experience in the automotive, marine, aerospace and construction field.
