AbstractThe article describes the occurrence of selected weather phenomena that are hazardous to aviation (thunderstorms, hail, fog and glaze) in Bydgoszcz. The work employs 1971–2010 data from the Bydgoszcz-Airport meteorological station. The hazardous atmospheric phenomena selected for analysis hinder or sometimes even prevent aviation. Of the analysed weather phenomena in Bydgoszcz, those most hazardous to aviation are fog and thunderstorms. The average annual numbers of days featuring them exceed 71 and 14, respectively. The analysis shows that statistically significant threats to aviation have decreased, e.g. number of days with fog (by 4.76 days/10 yrs) and days with thunderstorms (by 1.68 days/10 yrs). However, no clear trends can be seen for the number of days with hail (decrease of 0.14 days/10 yrs) and days with glaze (an increase of 0.16 days/10 yrs).

Occurrence Of Species

The vertical distribution of epiphytic bryophytes in European forests are still relatively poorly understood. The aim of the study was to analyse the diversity and vertical zonation of epiphytic mosses and liverworts on selected tree types (Quercus petraea, Betula pendula and Pinus sylvestris) within windthrow areas in the Kampinoski National Park (Central Poland). The investigations were performed in five parts of the trees: the tree base, lower trunk, upper trunk, lower crown, and upper crown. Deciduous trees have more species than pine trees (13 on Quercus and Betula, 8 on Pinus). The type of phorophyte was crucial for the differences in the species composition from the tree base to the upper crown that was observed. The highest richness of bryophytes was recorded on the tree bases, while the lowest was recorded in the upper parts of the crowns. The variability of the habitat conditions in the vertical gradient on the trunk that affected the patterns of the occurrence of species with different ecological preferences was determined using the Ellenberg indicator values. An increase in the value of the light and acidity indicators from the base of the trunk upwards and decreasing tendency in the case of moisture indicator was noted.
