Incubating Chelonian Eggs by Andreas S. Henning.
 
Incubating Chelonian Eggs provides an up-to-date source of incubation data for more than 200 turtle and tortoise species and subspecies currently propagated in captivity. 200 tabular overviews summarize information on humidity, temperature, clutch size, and incubation periods in a concise manner. Author Andreas Hennig furthermore describes suitable incubators, incubation substrates, control technology, and methods of applying temperature-dependent sex determination compiled not only from publications or personal experience, but from unpublished information gathered from numerous breeders he knows personally. It's sad to say, but many species won't survive without effective captive breeding and Andreas Hennigs book is a essential tool to do so.
