Methods of mathematical analysis in the study of organizations stylopidia pelvic limbs of land animals on the example of the European rabbit

Abstract

To study systematic organization of the femur Orycolagus cuniculus - was produced osteometric study of the femur 40 carcasses of domestic rabbits, as a tetrapod with different types of locomotion. Material and methods. Osteometry was carried out according to the original methodology, further statistical analysis of the contralateral femur was performed for isolated preparations of the right and left side. All absolute values of the linear structures were converted to relative values, per unit of measurement adopted by the transverse size of the diaphysis of the bone. It is revealed that the methods of descriptive statistics do not allow to reveal differences in the structure of the contralateral femur of the rabbit. Results. Factor analysis was conducted consistently to a depth of four-three-two-one factor based on the lateralization stylopodia bones of the pelvic limbs revealed General settings experiencing equivalent factor loadings in both groups of bone drugs. The results of correlation and factor analysis discovered the asymmetry of the systematic organization of the femur, with the predominant movements of greater amplitude of the left pelvic limb of a rabbit.
