  1. Contributions (%) to the total pollen amount are given per taxon (in descending order for the aircraft records), along with differences between sampling means (in parenthesis results from one-way, weighted-moments ANOVA is given, ***p < 0.001, **p < 0.01, *p < 0.05, ns: not significant relationship).
  2. Statistical analysis was performed for those taxa whose pollen contributed more than 0.5% to the total pollen concentration, respectively, for both car and aircraft sampling.
