Figure 4. M,/Cb functions of Talpa romána populations.Legend : cross in ring T. r. Macedonean, half-black circle- Т. r. Southern Italy, Two quaters-black circle - T. г. terra typica, full-blac circle - T . г . ehik i , full-black triangle - T. europaea (Hungary) In my opinion this proves, that the longer growing season and higher annual insolation and consequently better food supply cause greater variability of the populations. On the other hand a strong genetic relation can be seen among the populations, which is reflected in the common centre. The populations of Talpa romána are distributed along a common regression line, but with different centroids, which is caused by genetic isolation of the populations of common origin. 2.42. According to the results of regression analysis there is a strong correlation (P = 0,1 4) between maximal diameter of maxillar M. and rostral width, in the case of all the four Talpa romána populations. Equation of common regression line. у = 0,136 + 0,305x Equation of the regression line of Talpa romána ehiki у = 0,63 + 0,305x This latter refers to correlation at 5 % level of significance. 2.43. The coordinates of the centroids of Talpa romána populations in Figure 8 can be substituted for geographical location and climate goodness. 146
