The study of wood is key to the understanding of water transport and water relationships in trees, shrubs and climbers, and to the responses of these plants to climate change. In turn, the study of fossil wood is key to understanding the evolution of cells and tissues functioning in water conduction, mechanical strength, and storage and biological defence in woody plants.
In nine individual papers, this special issue of the IAWA Journal brings together information on fossil xylem from the earliest woody plants in the Devonian (420–360 Ma) to more recent woody floras from the Cenozoic, compared against the backdrop of the extant woody flora. Most papers were developed from presentations at the IAWA Symposium “Hydraulic Architecture through Time” held during the International Paleobotany Congress in Salvador de Bahia, Brazil, in October 2016. Others were invited at a later date. All papers take into account the latest insights in xylem evolution and the role of wood in tree biology and ecosystem functioning. Several woody form genera and species are named and described for the first time.
This book is aimed at researchers and students of paleobotany, plant evolution, wood anatomy, ecology, and climate change.
IAWA LIST OF MICROSCOPIC BARK FEATURES
by an IAWA Committee of 16 bark anatomists
and edited by
Veronica Angyalossy, Marcelo R. Pace, and Pieter Baas
Reprinted from IAWA Journal 37(4): 517–615 (2016)
Price of hard copies in special cover (paperback): EUR 13.00 (USD 15.00) plus postage. Special discounts will be given for bulk orders for teaching purposes.
This IAWA List of microscopic bark characters sets a new international standard for the definition and recognition of anatomical features of barks in woody angiosperms and gymnosperms. Codes are given for 173 anatomical character states to facilitate databasing the huge diversity of bark structure in trees and shrubs. It is richly illustrated with 169 splendid micrographs, virtually all in colour. An appendix gives practical guidance on methods for the microscopic study of bark.
The “IAWA Bark List” is not only indispensable for any future work on comparative bark anatomy and microscopic bark identification, but can also be used as a first inventory of functional traits in this complex tissue that is so vital for the physiology and protection of trees. Its significance can be compared with the IAWA Lists for Hardwood and Softwood Identification (1989 and 2004) that have been adopted by the entire international wood anatomical community.
The Bark List will also be a most valuable resource for advanced botanical teaching.

Natural and plantation forests, park and roadside trees, and even arctic, alpine and desert shrubs all depend on their wood or secondary xylem for hydraulic and mechanical fitness and biological defence. In recent decades the research community has become aware that the complex tissue of wood harbours a wealth of so-called functional traits that make natural and manmade ecosystems dynamic and sustainable. On the other hand, natural and anthropogenic stress factors such as prolonged or extreme droughts, floods, hurricanes and snow storms, which seem on the increase in our globally warming era, challenge the limits of functional xylem and phloem adaptations arisen over millions of years of adaptive evolution.
This special issue of the IAWA Journal brings together 12 papers by researchers collaborating in the Functional Traits Topic Group of the Cost-Action STReESS (Studying Tree Responses to extreme Events: a Synthesis) that was active from 2012 to 2016. Six papers are reviews of the literature dealing with the concept of functional traits in wood anatomy, and with individual functional traits such as porosity, various other growth ring markers, intra-annual density fluctuations (IADFs), inter-conduit pit membranes, vessel occlusions, and onset of sap conduction in earlywood vessels.
The other six papers contain a wealth of original results ranging from cambium dynamics and phloem formation to growth ring and IADF analysis in European and Tropical forests exposed at increasing frequency to extreme events. This book is aimed at the research community and advanced students of plant biology, forestry, wood science, and global change.

Beauty in wood by Steven Jansen, Peter Gasson, and E. A. Wheeler, Lulu, 2010.
31 pages ; incl. color illustrations ; 28 cm
Beauty in Wood is a photobook with contributions from over 30 wood scientists. The images showing the beauty in wood as viewed at different scales -- from attractive grain patterns visible at the macroscopic level to light microscope views of patterns of systematic value to electron microscope views of the minute features important to water movement in trees. Over 30 wood anatomists contributed photos. A few select references provide additional information on the topics illustrated.
The book is available for sale through Lulu Press, with profits going to IAWA. To buy this wonderful photobook, please visit lulu.com.
