This book presents studies on current vegetation topics, from polar to tropical regions. It is a festschrift to mark the 70th birthday of Prof. Elgene O. Box, who has studied vegetation all over the world, both through fieldwork and modeling. It reflects a number of his interests, including basic ecological plant forms (cf ‘plant functional types’), temperate-zone forests, and evergreen versus seasonal patterns. Section 1 discusses the concept of vegetation series, while Section 2 has two global-scale chapters on plant functional traits and whether they are related more to climate or phylogeny. Section 3 has nine chapters focusing on vegetation history, regional vegetation, and how these have influenced current species organizations and distributions. Regions treated include Russia, China, the USA, Mexico and Mediterranean areas. Lastly, Section 4 addresses aspects of vegetation change and plant ecology. Every chapter in this unique book offers original ideas on the topic of vegetation, as the authors are assembled from a world-wide population of leading vegetational ecologists, whose interests range from local communities to global theoretical questions.
