description <p>This research was conducted to investigate the dynamics of airborne fungi using viable culture collection and in respect to different abiotic variables, including seasonal and intra-diurnal variations. A gravimetric method was used to sample airborne fungal deposition on potato dextrose agar plates on alternate days, for a year between April 2015 to March 2016. From 176 settle plate exposures, a total of 1197 mould and 283 yeast colony-forming units (CFU), 21 genera and 62 species were retrieved. The highest fungal spore count was recorded in February 2016, whereas the lowest count occurred in August 2015. The main constituents of the fungal airspora were attributed to <em>Cladosporium</em> (60.2%), <em>Aspergillus</em> (10.4%), <em>Fusarium</em> (9.4%), <em>Alternaria</em> (8.5%), and <em>Ganoderma</em> spp. (2.3%). Temperature was negatively correlated with total colony count (<em>r</em> = −0.231, <em>p</em> ≤ 0.05) or species richness (<em>r</em> = −0.267, <em>p</em> ≤ 0.001), while wind speed was positively correlated with total colony count (<em>r</em> = 0.484, <em>p</em> ≤ 0.001) or species richness (<em>r</em> = 0.257, <em>p</em> ≤ −0.001). The highest dispersal of fungal spores was obtained at 18:00, whereas the lowest fungal spores release was recorded at 00:00 (midnight). There were no significant differences in species composition and richness of the airborne fungal population between two study sites, the Industrial area and Qatar University Campus. The count of <em>Alternaria</em> spp. and <em>Fusarium</em> spp. were significantly higher at the Industrial area site, which corresponds to a higher CO2 level than the Qatar University site. This study lays the foundation for future work to assess the implications of such aeromycological data on public health. </p> <h2>Other Information</h2> <p>Published in: International Journal of Environmental Research and Public Health<br> License: <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br> See article on publisher's website: <a href="https://doi.org/10.3390/ijerph18010182" target="_blank"><u>https://doi.org/10.3390/ijerph18010182</u></a> </p>
