    Opis:
    Common European ticks, Ixodes ricinus, have been found in forest areas situated within the boundaries of big cities, and in areas changed by anthropogenic pressure. Monitoring I. ricinus, in the areas used by the public for recreation and leisure, makes it possible to assess the risk of infection with the diseases they transmit. The objective of this study was the comparison of the seasonal activity of ticks, I. ricinus, in the afforested areas of the city of Olsztyn and its surroundings. Material and methods. This survey was conducted at sites located in the afforested areas of Olsztyn and within the Warmiński Forest situated about 15 km from Olsztyn. Ticks, I. ricinus, were caught every 10-14 days from April to October 2001 by the commonly applied method of flagging. During each catch, the temperature (T) and relative humidity (%RH) was measured with a thermohygrometer, 1 m above the duff level. Results. The tick population density at the Warmiński Forest site was higher than that at the sites within the city limits (116.8 and 20.5 ticks per 100 m², respectively). Two peaks of tick activity were recorded in this area - the spring peak in June and the autumn peak (much lower) in September. The activity of ticks in the afforested area within the city limits was much lower - only one (spring) peak occurred, which at most sites was observed in June. At all sites, included in the study, the peak activity of ticks was observed in April. Conclusion. The study suggests that the afforested areas outside the city are more dangerous to people than the area within the city because of the large number of ticks there.

    Opis:
    Investigations into the abundance of adult D. reticulatus in relation to the effect of climatic conditions (temperature, humidity) on host-seeking behaviour were conducted during the autumn (September-October) and spring (May) activity peaks in 2008–2009 in eastern Poland (51°25’N). The study was conducted in the same habitat where similar examinations were performed in 1999–2000. A comparative analysis revealed that the abundance of D. reticulatus had almost doubled within 10 years. Analysis of data on the humidity and temperature conditions prevailing during tick collection, and on tick abundance in the respective study periods in 1999–2000 and 2008–2009, as well as absence of climatic changes over many years, indicate that the increase in the numbers of ticks may have been a result of a multitude of other factors, e.g. weather or environmental conditions favourable for ticks and their hosts. The substantial differences in D. reticulatus abundance observed during the autumn activity peak (an increase from 126 and 128.6 specimens per collection in 1999 and 2000, respectively, to 247.3 in 2008) demonstrate the considerable effect of the biotic and abiotic conditions prevailing during the development of young and adult stages on the abundance of this tick species. The activity of adult D. reticulatus ticks in the autumn was 2.7-fold higher in comparison to that observed during the spring collection; the difference was statistically significant (p<0.0001). Females dominated in both seasonal activity peaks. The ratio between females and males during the spring and autumn peaks was 3.31:1 and 1.05:1, respectively. The increase in the abundance of the D. reticulatus population implies a higher risk of transmission of tick-borne diseases in the study area, and the necessity to develop and implement effective prevention methods and tick control programmes.

    Opis:
    Activity of soil dehydrogenase (DHA) was measured in the mineral soil in a forest stand of 15 to 16-year-old Scots pine (Pinus sylvestris L.) from geographically diverse populations, as an indicator of biological activity of soil microorganisms, in a provenance experiment in Poland. The pine populations originated from six European countries (Sweden, Russia, Latvia, Poland, Germany, France) and differed widely in aboveground biomass and productivity. Soil DHA during two growing seasons showed pronounced seasonal variability, which was significantly related to the fine root concentration of nonstructural carbohydrates. Higher DHA was found in soil under canopies of the central and southern European populations than in those from more northern parts of the Scots pine range. Significant positive correlation between soil DHA and aboveground tree biomass suggest that these patterns most likely resulted from differences in carbon dynamics and productivity among populations.
