“…However, this seasonal variation was different in rural and urban environments, showing that urbanization affected the temporal patterns in the foraging ecology of cats. In our study, and similar to the results of other, rodents were most often caught in autumn and early winter (Barrat 1997;Weber and Daily 1998), and this variability is most likely driven by distinct changes in their abundance, which is the highest in autumn (Goszczyński 1977). Interestingly, this seasonal change in the number of rodents brought home by cats seemed to be smaller in the urban environment.…”

The threat that domestic cats pose to wildlife has gained increased recognition by researchers and conservationists, and in this study, we investigated the seasonal variability and the effects of environment type (rural vs. urban) on the prey composition of free-ranging house cats in Poland. We analysed the variability in 307 monthly prey samples of different prey items killed by cats and brought to their owners (i.e., prey brought home by cats living in one home in one month) between 2002 and 2007 at 26 rural and urban sites. The variability in prey composition over time was analysed using additive models and canonical correspondence analysis. In total, we recorded 1348 prey items. Rodents were the most common prey in both environments, but shrews and reptiles were killed by cats more often in the rural environment while birds (mainly sparrows and pigeons) were more common in the urban environment. Additionally, prey composition changed seasonally. The pooled number of vertebrates killed by cats was largest in September and lowest in January, and rodents were killed most often in September, shrews and birds in June, and reptiles in April. The seasonal variation in the prey composition of cats was relatively high in the rural environment and more stable in the urban environment. Prey composition seemed to follow temporal and spatial variations in prey availability, thus confirming a facultative feeding strategy in free-ranging house cats.

“…Contrary to our results, in boreal and temperate zones (Goszczynski 1977, Angelstam et al 1984, Jędrzejewska and Jędrzejewski 1998, Hanski et al 2001) the diet of predators (red fox) was influenced by small mammal (in particular Microtus spp.) numbers.…”

“…The diet composition and feeding habits of the red fox, e.g., the preference for small mammals (e.g., Microtus species) or hare is known from studies in Europe (Goszczynski 1977, Macdonald 1977, Leckie et al 1998, whereas the feeding habits of the golden jackal are less well understood. In most studies no definite food preferences have been Figure 1 Geographic locality of the study area in Hungary (A), and habitat pattern of the study area (B).…”

“…The red fox is a typical searcher hunter as well as a food generalist, also utilising a wide range of small-sized prey types or plants and carcasses in European habitats (Englund 1965, Goszczynski 1977, Macdonald 1977, Ferrari and Weber 1995, Jędrzejewska and Jędrzejewski 1998, Leckie et al 1998).

Differences in food preferences between two sympatric canids, the golden jackal (Canis aureus), which is currently spreading from south-east Europe and is a little-known species in Europe, and the red fox (Vulpes vulpes) were investigated. Data on diet composition and food availability were collected over a 13-season period, in a temperate climate agricultural area of Hungary. We found that jackals and foxes preferred small mammals (Ivlev's electivity index, E i s0.38 and 0.39, respectively), and avoided towards wild boar (E i s -0.43 and -0.56, respectively) and cervids (E i s-0.92 and -0.94, respectively). Jackals preferred pheasant less than foxes (E i s0.06 and 0.51, respectively). Within small mammals, both predators preferred the open field living species, with the forest living species being less favoured. The relationship between the available biomass of small mammals, as the primarily important food resource for both canids, and the proportion of consumed biomass of small mammals was not close. This was probably as a result of abundant food resources and high trophic flexibility of the golden jackal and red fox allowing these two closely related carnivores to coexist sympatrically in Central European areas without resource partitioning.

“…It refers mainly to the study of predators, particularly weasels (Mustela spp.) and owls (Goszczyński 1977;Southern, Lowe 1982;King 1985). Effects of predators are considerably dependent on the environment heterogeneity, amount of the species of predators at the locality and availability of an alternative prey (Southern, Lowe 1982;Erlinge et al 1983;King 1985).…”

ABSTRACT:The population dynamics of wood mouse (Apodemus sylvaticus) was studied in three forest complexes differing in food supply in the intensively managed landscape of southern Moravia. They included an old semi-natural floodplain forest dominated by oak (HL), production broadleaved forest with the predominance of oak and robinia (HA) and a pheasantry with various forest stands consisting of diverse species and age categories of trees with a quantity of additional food for additional feeding of pheasants and roe deer (RB). The population fluctuation within six-year monitoring was affected by seed years (acorn crops in 2003 and 2006), which resulted in an increase in the species population density in the next year. Statistically significant effects of the crop of acorns on the body weight of monitored species were also detected (P < 0.01, F = 1.44). Relative abundance differed significantly between the floodplain forest (HL) and RB and HA (P < 0.01). The two last-mentioned sites did not differ and only a trend of greater preference to the most variable biotope in RB was noted. It evidences the unsuitability of floodplain forest for the species. In spite of the food specialization in small seeds significant effects of the excess crop of acorns can result in a rapid increase in the Apodemus sylvaticus population which can then cause damage to the natural regeneration of oak or artificial regeneration by seeding although to a substantially smaller extent than the more harmful A. flavicollis.
