Parasites have evolved numerous complex and fascinating ways of interacting with their hosts. The subject attracts the interest of numerous biologists from the perspective of ecology and behavioral biology, as well as from those concerned with more applied aspects of parasitology. However, until now there has been no recent book to synthesize this field. This book, written by leading authorities from the USA, Europe, Australia and New Zealand, provides the most comprehensive coverage of this important topic on the market.

The Scottish folklorist J.F. Campbell pieced together the tale of the Celtic Dragon, an intricate oft-told story involving not just dragons but mermaids, giants, and fairies. This story, or portions thereof, is found in many Indo-European folklore traditions, as far away as India. Campbell includes not only his merged narrative, but original Gaelic texts for two of the episodes. This book includes an introduction by George Henderson, the Gaelic text and an English translation of the related tale of Fraoch and the Dragon.
