Abstract
The age structure of sable samples has been analyzed on the basis of parameters obtained by three methods of age determination: by annual cementum layers (Klevezal, 1988), canine root canal width (Smirnov, 1960), and the degree of development of the mastication muscles and sagittal crest on the skull (Timofeev and Nadeev, 1955). It has been found that the first two methods produce similar results (r = 0.95) that are suitable for use in the practice of monitoring and commercial game management. The third method is simpler but less accurate and can be recommended only for the preliminary assessment of age ratios in populations. The results of such assessment by the method proposed by Klevezal are sufficiently accurate for a detailed analysis of population structure and dynamics of its reproductive core, but this method is laborious and involves a complicated histological procedure. When large samples are studied for the purposes of monitoring and management planning, the method proposed by Smirnov is preferable.
