This diploma thesis deals with the influence of biological, socioeconomic, environmental and also physiological and pathophysiological factors on isotopic ratios of δ13 C and δ15 N bone collagen of individuals with complete osteobiographic documentation. So far, isotope analysis has been used to reconstruct the diet of past populations, without considering the effect of non- nutritive factors. The aim of this work is to describe the effect of these factors on isotopic values of carbon and nitrogen in bone tissue of individuals. The material was processed by the stable isotope analysis. The bone collagen of ribs and femurs of 45 individuals (27 males and 18 females) who were members of several related families and occupied the territory of the Czech Republic during 19th-21st century was analysed. The age range of the subjects was 20-90 years. For correct interpretation of the results, a reference set consisting of eight samples of different animal species was analysed. Significant isotope differences between families with different social status have been demonstrated in this thesis. Individuals with higher status showed higher δ15 N values. The year of death of the individual was also reflected in isotopic values, and later living individuals showed slightly reduced δ15 N, which may be due to...
