This book provides an up to date source of incubation data of more than 200 turtle- and tortoise species and subspecies currently bred. 200 tabular overviews give information on humidity, temperature, clutch size and period of incubation. Further more Andreas Hennig describes useful incubators, breeding substrates and temperature dependant gender. He collected data not only from publications or personal experience, but also included unpublished information gathered from a lot of breeders he knows personally. Its sad to say, but many species wont survive without effective captive breeding and Andreas Hennigs book is a essential tool to do so.
