Abstract:
Atmospheric ascospores have been monitored using volumetric spore trap. Spore concentration data were analysed using Spearman's correlation. Our results show that the meteorological factor with the greatest effect on spore concentration was the duration of rain. Temperature increase strongly reduced the ascospore concentration; but the length of windless periods resulted in an increase in spore count. The only measurable effect wind perse actually had on spore count, was registered when a strong wind blew after a long windless period. We observed that the count of ascospores during wet weather could surpass the total concentration of dry conidia measured on a typical, highly polluted summer day. Using selected air samples to study the effect of storms, certain aspects of long-distance spore transport were elucidated. We describe here three main strategies for long-range ascospore transport, "splash-off", "secondary emission" and "sporematrix projectiles".
