Product Description

A group of special interest to mammalogists, taxonomists, and systemicists, ungulates have proven difficult to classify. This comprehensive review of the taxonomic relationships of artiodactyls and perissodactyls brings forth new evidence in order to propose a theory of ungulate taxonomy.

With this straightforward volume, Colin Groves and the late Peter Grubb cut through previous assumptions to define ungulate genera, species, and subspecies. The species-by-species accounts incorporate new molecular, cytogenetic, and morphological data, as well as the authors' own observations and measurements. The authors include references and supporting arguments for new classifications.

A starting point for further research, this book is sure to be discussed and hotly debated in the mammalogical community. A well-reasoned synthesis, Ungulate Taxonomy will be a defining volume for years to come.

Ungulate Taxonomy Review

This is one of the most monumental undertakings in taxonomic history and changes a lot of the preconceptions that we had about hoofstock. Every single taxa of Perissodactyla and Artiodactyla has been reexamined and new findings have been made based upon the best evidence to date. As the authors say, this should not be the final word on their taxonomy, but a starting point for more research to be done.

To give an example of some of the revisions, there is now one more species of rhinoceros that we had envisioned (the northern white rhino) and there are now eight species of giraffes instead of one.

This book uses both the latest in DNA evidence as well as traditional morphological data. The morphological data is in some area the first time this information has been published (being taken from the massive files and notes of the late Peter Grubb).

Some people will find some of the information hard to swallow as it can be so revolutionary, but when Groves did the same thing with primate taxonomy in 2001, his findings were quickly adopted by the majority of scientists.

Bovidae has had the largest revision with nearly double the number of species previously accepted. These new findings are also the basis for the Bovidae chapter in the recent Handbook of Mammals of the World vol. 2. Both of these books together will give a better understanding of the massive changes that have happened.

The only drawback to this book is the lack of charts, diagrams, and maps. The only charts present are tables of morphologic data in the form of skull measurements. Exact localities are hard to pinpoint. Phylogenetic trees are completely absent and would be most welcome if a 2nd edition were to ever be done. A phylogenetic tree would be most handy in explaining why the genus Tragelaphus has been split into 5 different genera.

No doubt, this book will spur endless debates, but its main goal it to elucidate how diverse the ungulate world really is and to give a better starting point for the conservation of significant populations heretofore neglected.
