Ferns are an integral part of the world's flora, appreciated for their beauty as ornamentals, problematic as invaders and endangered by human interference. They often dominate forest understories but also colonize open areas, invade waterways and survive in nutrient-poor wastelands and eroded pastures. Presented here is the first comprehensive summary of fern ecology, with worldwide examples from Siberia to the islands of Hawaii. Topics include a brief history of the ecological study of ferns, a global survey of fern biogeography, fern population dynamics, the role of ferns in ecosystem nutrient cycles, their adaptations to xeric environments and future directions in fern ecology. Fully illustrated concepts and processes provide a framework for future research and utilization of ferns for graduate students and professionals in ecology, conservation and land management.

Fundamental changes have occurred in all aspects of forestry over the last 50 years, including the underlying science, societal expectations of forests and their management, and the evolution of a globalized economy. This textbook is an effort to comprehensively integrate this new knowledge of forest ecosystems and human concerns and needs into a management philosophy that is applicable to the vast majority of global forest lands. Ecological forest management (EFM) is focused on policies and practices that maintain the integrity of forest ecosystems while achieving environmental, economic, and cultural goals of human societies. EFM uses natural ecological models as its basis contrasting it with modern production forestry, which is based on agronomic models and constrained by required return-on-investment. Sections of the book consider: 1) Basic concepts related to forest ecosystems and silviculture based on natural models; 2) Social and political foundations of forestry, including law, economics, and social acceptability; 3) Important current topics including wildfire, biological diversity, and climate change; and 4) Forest planning in an uncertain world from small privately-owned lands to large public ownerships. The book concludes with an overview of how EFM can contribute to resolving major 21st century issues in forestry, including sustaining forest dependent societies.

Forests cover approximately 30% of total land area and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. The canopy is one of the uppermost levels of a forest, below the emergent layer, formed by the tree crowns. The canopy is home to unique flora and fauna not found in other layers of a forest. Trees in the canopy are able to photosynthesise very rapidly thanks to the large amount of light, so it supports the widest diversity of plant as well as animal life in most rainforests. This book presents a wide variety of topics on the ecosystem in forest canopies. Included is a study on light distribution patterns and how it effects the daily photosynthesis of herbaceous vegetation. Recent progress, concerns, and future directions in simulations of vegetation processes are presented as well, in the terrestrial biosphere model that is coupled to a climate system model.

Contributed to by leading experts, this book looks at the history of coppice woodlands, their physical environment, the different management techniques used and their effects on the flora and fauna. The implications of this for conservation is controversial and this is debated in a lively way in many of the chapters.
