In order to study the body size of wild boar Sus scrofa Linnaeus, 1758 during the Boreal and Atlantic Chronozones in southern Scandinavia, 12 measurements of teeth and bones from 32 Mesolithic sites from Scania (Sweden) and Zealand and Jutland (Denmark) were analysed. The Osteometrie analysis revealed that the body size of wild boar from Scania did not change during the period. The results indicate that the changes of ecological conditions during the transition from the Boreal to the Atlantic chronozones did not affect wild boar in the same way as red deer and roe deer, which decreased in body size during the period. The tooth size of wild boar from Zealand is smaller than in wild boar from Jutland and Scania during the Late Atlantic Chronozones, which probably is the result of the isolation of the population when Zealand became an island. Calculations of withers height show that wild boar in southern Scandinavia during the Atlantic Chronozones were of similar body size as recent wild boar from eastern Europe.

Investigations have been done on 18 carcasses of wild boars including their cutting to main elements and detailed dissection of received parts of carcasses. It was found that the bigest element of wild boars carcass is a ham. High participation of neck shoulder and low participation of jowl is also characteristic. In comparison to the hog carcass the estimation of tissue composition showed not large quantity of adipose tissue and considerably higher mass of bones. Most valuable elements of wild boars carcass were ham and shoulder blade. The work confirms high useability of wild boars carcasses.

The wild boar is an omnivorous animal, and by foraging (rooting) disturbs the top soil layer. In some regions of Poland and Europe seasonal fluctuations in rooting have been observed. Wild boars not only eat plants, but also strongly modify their habitat. In Białowieża National Park wild boar most frequently visit oak-hornbeam forests on fertile soil. On sites where the forest floor is covered with dense vegetation the germination of seeds is difficult, and wild boar rooting can promote the removal of diaspores from deeper layers of the soil seed bank. Within a 3-year observation on 30 subplots about 10,000 seedlings emerged representing 38 species. Our study revealed that rooted patches are characterised by a very rich and diverse flora of seedlings representing mostly forest species, but their density is low. The dominant species germinating in the disturbed ground vegetation is Urtica dioica, a species forming the persistent soil seed bank. There is a possibility that seedlings of herbaceous plants emerging on permanently rooted patches are of exogenous origin, since the seeds germinating there were in many cases damaged by repeatedly rooting animals and had no chance for further growth and reaching the generative phase. However, the soil seed bank in the rooted area has to be analysed to confirm this theory, that they have exogenous or endogenous origin. Seedling density in a repeatedly rooted oak-hornbeam forest is determined by factors other than those related to rooting. In this context the present study did not demonstrate a negative impact of rooting intensity on seedling emergence.

Comparative coproscopic studies on the occurrence of helminths in the wild boar included two groups of animals living under different conditions: one (A) - wild boar inhabiting a woodland area, another (B) - wild boar from a free-range farm. Analysis of 142 samples of faeces revealed the occurrence of six nematode species: Oesophagostomum sp./Globocephalus sp., Metastrongylus sp., Trichuris suis, Ascaris suum, Ascarops strongylina, and Physocephalus sexalatus. The prevalence of infection was very high - 97.2%, while the mean number of eggs was 34.3 ±88.6. The prevalence was similar in the two groups: A=98.4% vs. B=96.3%. The mean number of eggs was higher in group B (46.6 ±115.3; range 1-902) compared to A (18.3 ±17.2; 1-83). All the parasite taxa were found in each group. The frequency of individual helminth taxa differed between the groups, but the differences were statistically significant only for Oesophagostomum sp./Globocephalus sp. (χ²=4.34; df=l; P=0.037), Metastrongylus sp. (χ²=8.03; df=2; P=0.004), and A suum (χ²=15.67; df=2; P=0.000).

This study presents the first molecular and serological evaluation of Echinococcus granulosus infections in wild boars in Iran. Twenty five wild boars were collected in south-western Iran, during authorized hunting program, from March to October 2013, necropsied and examined for E. granulosus infection. Furthermore, seroprevalence of cystic echinococcosis in hunted boars was evaluated by an ELISA system. A fertile hydatid cyst due to E. granulosus was detected in the lung of one of the animals. Genotype analysis of the isolate was determined by analyzing a mitochondrial gene, cytochrome C oxidase subunit 1 (co1). DNA was extracted from the cyst sample and polymerase chain reaction amplification and DNA sequencing of the specific region of the co1 gene was performed. Molecular evaluation confirmed the presence of a sheep strain, the G1 genotype, in the wild boar in south-western Iran. This is the first report of the presence of G1 genotype of E. granulosus in wild boar in Iran. Serological evaluation of hydatid cyst by antigen-B ELISA revealed E. granulosus antibodies in 5 (20%) of 25 wild boars. A statistically significant difference was observed between the prevalence of E. granulosus antibodies and gender while the difference between the seroprevalence of E. granulosus and age was insignificant. Findings of this study might have important implications for the prevention and control of cystic echinococcosis.

Location of nests, built by free-living wild boars Sus scrofa Linnaeus, 1758, was analysed in order to assess the importance of environmental and social conditions in piglets' survival during the first days after birth. The research was carried in a Mediterranean forest with different habitats and high density of natural predators. The results indicate that most nests were already constructed before the beginning of March, being located preferentially in areas with: (1) abundant plant cover, (2) water nearby and (3) a warmer temperature than in other places. These results suggest that female wild boar try to diminish mortality caused by natural predators by constructing their nests in places with dense cover. Water is very important because of the females' new necessities derived from milk production. Warm nesting places might diminish deaths after birth in a species with important thermoregulation deficiencies. The distance between nests is also important because in this period the wild boar develops a territorial behaviour, possibly with the objective of establishing bonds between the mother and her offspring before returning to the familiar units made up of several females and their piglets, all of them of a similar age.

Meat juice and serum samples from hares and wild boars were used in the ELISA for the examination for the presence of anti-Brucella antibodies. A high correlation between meat juice ELISA and serum ELISA was obtained. All 9 meat juice samples from hares with anatomopathological lesions characteristic of brucellosis (from 8 animals Brucella was isolated) were positive in the ELISA, similarly as sera. Out of 46 remaining hares only 1 reacted positively in the meat juice ELISA and it was not confirmed by the serum ELISA and other methods. As concerns the material from wild boars 12.3% of sera (out of 933 samples) and 13.7% of meat juice samples ( out of 336) were positive in the ELISA. Among 48 serum and meat juice samples coming from the same animals, 6 samples were positive both in the serum ELISA and meat juice ELISA and 42 were negative. The meat juice ELISA proved to be a valuable method for testing both hares and wild boars for anti-Brucella antibodies.

This paper presents the results of studies on the content of polychlorinated biphenyls (PCBs) in the fat of wild boars and roe-deer shot in the region of Warmia and Mazuria during the 1993 hunting season. PCB levels in the adipose tissue of these animals were relatiely low. The average PCB content in wild boar fat was 21.8 μg/kg, and in roe-deer 9.7 μg/kg. PCB content was below 15 μg/kg in the majority of wild boar fat samples, and below 7 μg/kg in the case of roe-deer.

To determine the helminth fauna of wild boars, 160 stomachs and intestines, 72 lungs and 58 livers of animals from eight areas in Corsica, have been examined. It is the first study made in this Mediterranean island. The evaluation of the helminthic composition revealed six following species: Dicrocoelium dendriticum (Rudolphi, 1819), larval stage of Echinococcus granulosus (Goeze, 1782), Ascaris suum (Goeze, 1782), Metastrongylus sp., Globocephalus urosubulatus (Alessandrini, 1909), Macracanthorhynchus hirudinaceus (Pallas, 1781). Differences among prevalence data indicated an overdispersed helminth distribution in Corsica.

Partial sequence of mitochondrial ND1 gene was obtained from Echinococcus granulosus isolate from a wild boar (Sumy region, Ukraine). It has been found to be identical to the sequence of G7 (pig) strain of E. granulosus, which was earlier found in pigs from the same region. It is supposed that in some areas wild boars may support the existence and propagation of the pig strain of E. granulosus.
