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
