Abstract: | Ganoderma sp. is an airborne fungal spore type known to trigger respiratory allergy symptoms in sensitive patients. Aiming to reduce
the risk for allergic individuals, we analysed fungal spore circulation in Szczecin, Poland, and its dependence on meteorological
conditions. Statistical models for the airborne spore concentrations of Ganoderma sp.—one of the most abundant fungal taxa in the area—were developed. Aerobiological sampling was conducted over 2004–2008
using a volumetric Lanzoni trap. Simultaneously, the following meteorological parameters were recorded: daily level of precipitation,
maximum and average wind speed, relative humidity and maximum, minimum, average and dew point temperatures. These data were
used as the explaining variables. Due to the non-linearity and non-normality of the data set, the applied modelling techniques
were artificial neural networks (ANN) and mutlivariate regression trees (MRT). The obtained classification and MRT models
predicted threshold conditions above which Ganoderma sp. appeared in the air. It turned out that dew point temperature was the main factor influencing the presence or absence
of Ganoderma sp. spores. Further analysis of spore seasons revealed that the airborne fungal spore concentration depended only slightly
on meteorological factors. |
