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.

Ferns existing today represent a genetic inheritance of great value as they include species of ancient vascular plants, which have direct connection with the crucial steps done in the past for settling life on Earth. Their life cycle is an example of alternation of generations, in which both a multicellular diploid organism and a multicellular haploid organism occur and give rise to the other. Spore, gametophyte and sporophyte have been studied either for basic and practical purposes. In the first case, they offer us simple and easy to grow experimental systems to investigate on plant development, and secondly, they are culture by their ornamental appeal, their environmental benefit or as source of metabolites. This timely volume brings a selection of chapters, each one composed by experts in their respective fields. The chapters included cover a broad range from the knowledge of its biology and contribution to understanding of plant development, useful protocols for propagation and conservation purposes, genetic variability as well as environmental and theurapeutical applications. This wide spectrum of the contributions gives to reader a rapid idea of the enormous potential of this plant group. The originality of this book is to expose the most recent tendencies in their investigation, which is far from the traditional perspective usually followed. The collected articles in this volume incorporate most of novel techniques used nowadays routinely to resolve traditional questions. Ashwani Kumar Professor, Department of Botany, University of Rajasthan, Jaipur. The author’s repertoire of published works spreads across 150 research articles in various national and international journals. He has an experience of over three decades in his field of research, namely, tissue culture and biochemistry, being awarded with prestigeous V. Puri Medal in 2008 for his services to advancement of Botany. Helena Fernández Associate Professor, Department of Biology of Organisms and Systems, Oviedo University, Spain. Her research focuses on micropropagation and reproduction in ferns during the two last decades. In 2002 she obtained the award “Ramón y Cajal” by The Ministry of Science and Technology, being engaged to the Oviedo University as tenurer, full time, in the Area of Plant Physiology since then. M. Angeles Revilla Plant Physioloy Assistant Professor in the Biology Faculty at the Oviedo University (Spain) since 1987. Twenty years experience in plant tissue culture. She has also worked in cryopreservation and genetic stability for the last ten years, mainly in the development of protocols for in vitro shoot apices in agronomic species.
