On the occasion of the 50th Anniversary of the International Association of Wood Anatomists several symposia were held during the 13th International Botanical Congress in Sydney, August 1981. Extended versions of most of the invited papers presented there, and some additional papers on aspects which could not be included in the congress program constitute the contents of this book, which intentionally received the pretentious title 'New Perspectives in Wood Anatomy'. To some readers it may seem a paradox that under this heading papers on a diversity of partly traditional wood anatomical subjects are assembled, even including two with a historical emphasis. However, a study of the history of wood anatomy and of how students of that discipline joined forces in an inter national association, brings to light many facts and views which deserve the attention of present day and future wood scientists as a potential source of in spiration for their research and organisational work.

This atlas presents macroscopic descriptions, macro cross section pictures, general characteristics and identification keys of 335 wood species currently introduced in the European timber market from all over the world. Overall 292 different genera are represented and CITES-listed timbers are also included. Macroscopic descriptions are based on a recently proposed list of macroscopic features for wood identification. Macroscopic features and their codes are defined and illustrated in the atlas. Wood descriptions also include information about natural durability, physical and mechanical properties, end uses, environmental sustainability and possible related misleading commercial names. Furthermore, each genus is described in terms of number of species, geographical distribution and main commercial timbers, and details are given about to what extent timbers within the genus can be typically identified through macroscopic and microscopic analysis, if any. The atlas will be a valuable guide for all agents in charge for timber verification, those involved in the European Timber Regulation enforcement and CITES inspections, as well as wood scientists, foresters, wood sellers, wood restorers, and any wood worker and wood passionate interested in a fast and reliable tool for wood identification.

Forest trees constitute one of the major resources of the world and their utilization, either for structural purposes or for the materials which they yield, dates back to antiquity. Over the centuries, the exploitation of this resource has become progressively more sophisticated, and, in many parts of the world has led to the development of highly complex forest-based industries. The research and development work which led to these industrial uses fostered the formation of numerous technical societies and associations, which, through their meetings and publi cations, have facilitated communication and the exchange of ideas. Over the years, there have been numerous symposia devoted to wood and the many facets of its properties and utilization. However, rarely has the emphasis in such symposia been placed upon the living tree and the changes which it undergoes in relation to its ultimate utilization. Hence the Phytochemical Society of North America arranged the symposium, "The Structure, Biosynthesis, and Degradation of Wood", held at the University of British Columbia in August, 1976. the contributions to which form the basis of the present volume.

Wood composites have shown very good performance and substantial service lives when correctly specified for the exposure risks present. The selection of an appropriate product for the job should be accompanied by decisions about the appropriate protection, whether this is by design, by preservative treatment, or by wood modification techniques. This Special Issue, “Advances in Wood Composites II”, presents recent progress in enhancing and refining the performance and properties of wood composites by chemical and thermal modification and the application of smart nanomaterials. Such enhancements and refinements have made wood composites a particular area of interest for researchers. In addition, this Special Issue reviews some important aspects in the field of wood composites, with particular focus on their materials, applications, and engineering and scientific advances, including solutions inspired biomimetically by the structure of wood and wood composites. This Special Issue, as a collection of 14 original contributions, provides selected examples of recent advances in wood composites.

Wood anatomy, the study of woody cells and tissues, has advanced considerably since the early descriptive accounts were made which consisted mainly of cataloguing what was 'out there'. Anatomical data have been applied in better understanding of the interrelationships of woody plants, confirming evidence of natural relationships of plant families in combined analyses. This book will serve its purpose well, for Undergraduates of Forestry. Wood is composed mostly of hollow, elongated, spindle-shaped cells that are arranged parallel to each other along the trunk of a tree. The characteristics of these fibrous cells and their arrangement affect strength properties, appearance, resistance to penetration by water and chemicals, resistance to decay, and many other properties. Just under the bark of a tree is a thin layer of cells, not visible to the naked eye, called the cambium. Here cells divide and eventually differentiate to form bark tissue to the outside of the cambium and wood or xylem tissue to the inside. This newly formed wood (termed sapwood) contains many living cells and conducts sap upward in the tree. Eventually, the inner sapwood cells become inactive and are transformed into heartwood. This transformation is often accompanied by the formation of extractives that darken the wood, make it less porous, and sometimes provide more resistance to decay. The center of the trunk is the pith, the soft tissue about which the first wood growth takes place in the newly formed twigs. The book will be helpful in imparting theoretical skills to the students, academicians and teaching faculty of the forestry and agricultural disciplines working in field of woody plants. This book is intended to impart basic education for the UG students of Forestry for the course Wood Anatomy.
