Habitual loading patterns of domesticated animals may differ due to human influence from their wild counterparts. In the early stages of human-reindeer interaction, cargo and draft use was likely important, as well as corralling tame reindeer. This may result to changes in loading as increased (working) or decreased (captive) loading, as well as foraging patterns (digging for lichen from under the snow versus fed working and/or captive reindeer). Our aim is to study whether differences in activity modify variation in bone cross-sectional properties and external dimensions. Our material consists of donated skeletons of modern reindeer: 20 working reindeer (19 racing and one draft), 24 zoo reindeer, and sample of 78 free-ranging/wild reindeer as a reference group. We used general linear modelling to first establish the total variation in cross-sectional properties among wild and free-ranging reindeer, and then to infer how differences in loading modify observed variation among zoo and working reindeer. According to our results, direction of greater bone quantity as well as external dimensions in of radioulna of female reindeer differs from female reference group, likely relating to foraging behavior. External dimensions of humerus differ in working and zoo male reindeer compared to male reference group. Increased robusticity of long bones, especially of tibia among working male reindeer, may indicate increased loading, and increased cortical area of long bones may indicate sedentary lifestyle among female reindeer. The results of this study can be used to understand early stages of reindeer domestication by observing reindeer activity patterns from archaeological material.

“…Treatment had successfully removed the parasite burden; however, associated inflammation remained and, in combination with the lymphangiectasia, resulted in malabsorption and hypoproteinaemia. Closure of the rib growth plates in reindeer is recorded as occurring from around three years of age, 2 and the early closure in this case suggests a significant growth check, most likely due to PGE.…”

“…The epiphyseal fusion stage (Hufthammer 1995;Takken Beijersbergen and Hufthammer 2012) was used to determine the age of each individual. For analysis purposes, the bones were then divided into age groups based on their fusion time (Table 6).…”

“…The proximal end of the radius fuses between 4-10 months in reindeer (Hufthammer 1995;Takken Beijersbergen and Hufthammer 2012) and would thus be excluded when found without its distal end. An LDA of the measurements showed that they can be sexed with in the 10% error margin (ECE = 0.08, n = 20).…”

Takken Beijersbergen, L.M. 2017. Heaps of fascinating fragments: reconstructing a medieval reindeer population based on bone middens from the Hardangervidda high mountain plateau, Norway. -Acta Zoologica (Stockholm) 98: 340-361.The results of a detailed morphological and pathological study on reindeer bones (Rangifer tarandus) from four medieval hunting stations on Hardangervidda are presented. As intensive marrow collecting left almost no bones intact, traditional sexing methods could only sparsely be applied. Alternative methods had to be explored to successfully assign the fragments to a sex. Employing linear discriminant analysis (LDA) on early-and non-fusing skeletal elements, I have shown that (incomplete) calcanei, metapodia and phalanges I and II can be used successfully to assign a specimen to a sex and should no longer be excluded from osteometric analyses. Differences in the demographic compositions of the taphocoenoses lead to the assumption that hunters in the 11th century AD targeted large reindeer bucks, while at the 13th-century sites, the complete biocoenose is represented, albeit in a different ratio. There seems to have been a shift in hunting technique: from selective hunting to mass hunting. Size wise, the reindeer from Hardangervidda were smaller than reindeer from contemporary assemblages from the Dovre area (central Norway), a population that is genetically different. Few pathologically affected bones were encountered in the material, but some cases of infections, bone lesions and a progressed osteosarcoma are described. Liselotte M.
