Lanszki J., Sárdi B., & Széles L. G.: Feeding habits of the stone marten 239 Martens living in villages and farms consumed in great proportion prey species linked to human environment (39.9%, or 46.8%, respectively), and mixed (living both in wild and human environment) prey species (52.9%, or 45.1), while wild living prey species were eaten in low proportions (Fig. 3d). The consumption ratio of the human-linked prey species in villages the lowest (20.8%) was in Nagyszakácsi, and the highest (65.2%) was in Felsőmocsolád, while on farms ranged between 33.9% (Somogyjád) and 68.7% (Mernye). The habitat type dependent difference was not significant in any case of the groups (tjo=0.34-0.80, P=0.442-0.744). The distributions of prey depending on human association in the diet of martens living in the two habitat types was not significant (X22=4.76, P=0.093). Consumption of domestic animal, rodent pests and garbage Martens living in villages and farms also consumed in a quite high ratios of domestic animals (Table 2). In the animal food, the poultry and the poultry egg was found in the largest biomass ratio in Mernye (47.9%) and in Polány (43.1%, from this part of domestic rabbit 0.9%). Pigeon at the farm in Somogyvár (0.2%) and at Felsőmocsolád (5.9%), pig at Nemesvid (0.6%), cat at inner-district of Somogyvár (0.5%) were consumed. In Kisgyalán remains of a parrot (budgerigar), which had been flown away from a house was detected in a scat. Consumption of pet food was found in samples collected in Somogysimonyi (2.4%) and in Polány (3.2%). In a sample collected in Somogyjád, remains of a dog (0.4%) were found. Consumption of domestic animal carrion (and scraps of meal or kitchen offal) - by simultaneous occurrence of carrion and fly pupa - were been significant at such locations (Nemesvid 33%, Nagyszakácsi and Somogyjád 25%, and Kisgyalán 19%). In animal food, consumption ratio of house mouse and brown rat according to biomass calculation were over than 10% at many of settlements (Table 2). The consumption of these harmful small mammals was especially high on the Memyeszentmiklós farm (41.9%) and on Felsőmocsolád (28.9%). In marten scats numerous, originally indigestible material occured, such as pieces of wood (in 51 cases), pieces of tile/brick scrap (12), nylon and straw (10-10), string and wall pieces (9-9), aluminium foil and paper (8-8), piece of rubber (7), salami husk (6), acrylic string (4), slag (3), power cable, limestone and leaf (2-2), styrofoam, sponge, mineral wool, rag, iron-, ceramics scrap, sheep wool and unknown substance (1-1). In the case of martens living in villages, the relation the indigestible material and the food elements compared was 4.5: 95.5, while in case of farms 3.8: 96.2. The habitat type dependent difference was not significant (x2j=0.75, P=0.388). Relationship between stone marten and barn owl In some cases (e.g. in Nemesvid, Polány and Memyeszentmiklós) samples were collected from both predators in a large sample size (Fig. 4). But in numerous locations either marten scats (e.g. in Felsőmocsoládi farm, Somogysimonyi, Mernye and Gamás), or owl pellets were only found (e.g. in Mesztegnyő, Buzsák, Ecseny and Felsőmocsoládi church). Distribution of marten scat and owl pellet numbers significantly different by location (X2i9=1733.38, PO.OOOl).
