Book Description
At present the only method available for age determination of woodchucks does not provide a means for separation of physiologically mature woodchucks into specific chronological age classes. Previous studies of mechanisms for aging woodchucks have dealt primarily with gross morphological features of the animals. This thesis involved a histological examination for annulations in the cementum of teeth and in the periosteal zone of bones that might be correlated to age of the woodchucks. A comparison of incisor measurements to age classes that were determined by annuli counts is also presented.

Book Description
This text focuses on the principles and methods of using growth layers formed in teeth and bones of mammals to make a judgement on essential traits of the animal's life history. In nearly all mammalian species, including man, the age of individuals can be determined from the number of growth layers and, at least in some of them, it is possible to estimate the season of an animal's birth and death, age of sexual maturation, periodicity of reproduction, certain feeding habits and other aspects of the individual's biology. It is also possible, from tooth-enamel analysis, to assess doses of radiation accumulated by animals and human beings during their lifetime.;This book is intended for zoologists, wild-game biologists and zoo archaeologists, but some of the sections could also be of interest for anthropologists, radioecologists and conservation biologists.
