Lagomorphs are a mammalian order which includes rabbits, hares and pikas. They are distributed throughout the world and are of both scientific and public interest as they are classified between endangered and pest species. In addition, some have a high economic value as important game species. In the last few decades, a huge amount of information was made available to the scientific community and resulted in remarkable advances on all aspects of Lagomorph biology. However, this information is dispersed in multiple scientific and non-scientific journals. This book provides an updated synthesis of the current knowledge on Lagomorph biology.
