From the reviews: This volume ... focused on a variety of topics relevant to PWD, including the threat to forest ecosystems, a summary of the current state of PWD research and insights into future scientific developments. ... the coverage of this book is comprehensive, each chapter providing an interesting and authoritative account of the current developments in PWD research. ... this is a useful, reasonably up-to-date and competently executed volume that justifies a niche on the shelf of all those involved in the PWD arena.
