Fluctuating asymmetry in the horns of Siberian roe deer, interrelation with trophy evaluation

The research of asymmetry in trophy business is actual in connection with increasing quality of hunting farming and keen interest in trophy tourism. Similar researches give the chance for the analysis of trophy qualities of certain animals in population or in the kind. The research of fluctuating asym-metry can be useful to the solution of problems of environmental protection, control of conditions of populations of deer and biomonitoring. For deter-mination of the fluctuating asymmetry in horns of Siberian roe and identification of interrelation with a trophy assessment experiment with group of sam-ples was made. Two methods were used: 1) inter- national trophy assessment of CIC; 2) checks of equality of average values in two selections with the use of t-criterion for identification in examples of the fluctuating asymmetry. The measurements of eighteen samples of horns of the Siberian roe with definition of trophy assessment of CIC were taken for this purpose. The samples were divided into two groups, depending on the territory of production: the first group was Mansky area, the second group was Beryozovsky area of Krasnoyarsk Region. Three measurements were taken: 1) the length of the main trunk; 2) the length of supraorbital out-growth; 3) the length of back outgrowth; they were investigated by the method given above. The re-search showed that all the samples had the signs of fluctuating asymmetry, i.e. insignificant devia-tions from bilateral symmetry. The first group re-ceived more CIC appreciation. The horns in the first group were larger, but less symmetric. The second group had more symmetric horns, but lower trophy mark as the sizes of horns were less. More appre-ciation was received by horns with bigger asym-metry. The criterion of symmetry relative was also measured "by eye". Calculating the symmetry mathematically we may say, that small copies have an opportunity to get higher point thanks to good symmetry. Among themselves groups had insignifi-cant distinctions explained by adjacent territories of dwelling, free movement of individuals from one territory to another and belonging to one popula-tion.
