From the reviews: "It provides a very worthwhile introduction to a topic that is receiving a lot of attention among phylogeneticists in the new millennium: how to combine the information contained in multiple phylogenetic trees with partially overlapping sets of taxa. ... this book achieves what it sets out to achieve, which is to provide an overview and evaluation of possible approaches to the construction of supertrees. ... This book does a good job of explaining the arithmetic and the mathematics of supertrees ... ." (David A. Morrison, Systematic Biology, Vol. 55 (3), 2006)
