Gross external morphological parameters have been the most common area used by researchers to attempt to define identifying characteristics.This is at least in part due to the relative ease of data collection using these structures compared to features requiring the use of more complex laboratory methods. Morphological criteria have included a variety of structures and parameters including external body measurements, and coloration. Morphology is an area of research where the shape and size of a morphological individual or characteristic is described with quantitative 2 analysis, and because of very low heritability (h), morphology characteristics are very dependent on external conditions (Oxnard 1978). Multivariate statistical methods were applied to classify morphology differences and using these methods it was possible to evaluate the most important characteristics separating the subpopulations defined by wild boar. Relatively little data are available on the relationships among morphological parameters of wild boar.This data mostly dealing with growing patterns of different parameters were analyzed and some results were presented on the correlations and allometry of these characteristics. Better management of wild boar populations requires more morphological data. Therefore, the aim of this study was 1) to determine morphological differences among wild boars populations located in three Croatian geographical regions using morphological measurement; and 2) determine the existence of hybridization. MATERIALAND METHODS– Material i metode) From October 2007 to January 2009, sampling of wild boar populations was conducted in three Croatian geographical regions, East (Đakovo, Baranja, Bilogora) Central (Lpolje, Banija) and West (Plominska, Oprtalj, Grožnjan, SjVeleb, VelKapel, LicSredo) (Fig 1), where we covered three characteristic climate areas under Köppen’s climatic classification. The Eastern and Central region enjoys the Cfb climate, but on the other hand theWestern region is under the influence of the Cfa and Df climate (Šegota &Filipčić 2003).
