There is a strong movement towards uneven-aged forest management based on the idea that such stands increase or at least maintain soil fertility, increase biodiversity, and improve stand resilience. This shift in forest management practice renders existing yield tables increasingly unreliable. Among potential alternatives are tree growth models, because they predict the growth of each tree within a forest stand. This book summarizes three years of work related to the topic, carried out as a joint effort of leading tree growth modellers across Europe together with forest companies. By means...

Despite their importance in sustaining livelihoods for many people living along some of the world s most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against...

It was the botanist Ernst Munch, who separated the plant into two principal compartments, the "dead" apoplast and the living symplast. Only during the last 20 years cell walls attracted the interest of a broader group of plant scientists. We know today that apoplastic functions are much more diverse. The apoplast may be considered as "the internal physiological environment of plant bodies," that essentially maintains homeostasis. The term 'cell wall' may be misleading, since the chemical and physical properties of cell walls are not fixed but rapidly respond to environmental stimuli. This...

Wood was essential to the survival of the Venetian Republic. To build its great naval and merchant ships, maintain its extensive levee system, construct buildings, fuel industries, and heat homes, Venice needed access to large quantities of oak and beech timber. The island city itself was devoid of any forests, so the state turned to its mainland holdings for this vital resource. A Forest on the Sea explores the history of this enterprise and Venice's efforts to extend state control over its natural resources.

Karl Appuhn explains how Venice went from an isolated city...

This volume provides an overview of recent advances in forest ecology on a variety of topics, including species diversity and the factors that control species diversity, environmental factors controlling distribution of forests, impacts of disturbances on forests (fires, drought, hurricane), reproduction ecology of both trees and understory species, and spatial organization of forests. Previously published in Plant Ecology, Volume 201, No.1, 2009.
