Abstract Introduction Fungal spores constitute an important fraction of bioaerosols in the atmosphere. Objectives To analyse the content of Alternaria and Cladosporium spores in the atmosphere of Beja and the effect of meteorological conditions on their concentrations. Methodology The daily and hourly data of Alternaria and Cladosporium fungal spores concentration in the atmosphere of Beja were monitored from April 12, 2012 to July 30, 2014, based on the Portuguese Aerobiology Network methodology.The influence of meteorological conditions on the studied types of fungal spore concentrations was assessed through Spearman's correlation analysis.Results During the study period, 20,741 Alternaria spores and 320,862 Cladosporium spores were counted. In 2013, there were 5,822 Alternaria spores and 123,864 Cladosporium spores. The absolute maximum concentrations of Alternaria and Cladosporium spores were recorded on November 8, 2013, with 211 and 1301 spores/m 3 , respectively. Temperature,

Airborne Cladosporium and Alternaria spore concentrations through 26 years in Copenhagen, Denmark

“…However, annual Cladosporium SIn averages over 1993-2009 at 10 out of 12 stations in the Iberian Peninsula had lower values: 54,459-238,214 Spores day m -3 , with higher values in Merida (579,953 Spores day m -3 ) and Sevilla (933,485 Spores day m -3 )(Aira et al 2012). Annual SIn, lower than 3-month SIn averages in Denmark, were reported for Southern Portugal(Almeida et al 2018) and Madeira Island(Sousa et al 2016) at 92,351 -123,863 Spores day m -3 , and for the Western Thrace region in Greece at 120,464 Spores day m -3(Katotomichelakis et al 2016). Cladosporium SIn values close to or lower than the 3-month Copenhagen Cladosporium SIn were reported for northern Poland (annual SIn = 392,670 Spores day m -3 )(Bednarz and Pawlowska 2016) and North-West Morocco (SSIn 296,707 -417,929 Spores day m -3 )(Bardei et al 2017), whereas annual SSIn reported for western and eastern Poland were at least twice higher than the 3-month Copenhagen Cladosporium SIn(Kasprzyk et al 2016;Weryszko-Chmielewska et al 2018).…”

“…Seasonal length, however, does not appear to correlate with Alternaria spore abundance: relatively short Alternaria seasons in northern locations can have higher Seasonal Spore Integral (SSIn) values than those in locations with longer seasons (Skjøth et al 2016). A similar geographical pattern seems to be true for Cladosporium: longer seasons in the South with bi-modal distributions and lower SSIn (Katotomichelakis et al 2016;Sousa et al 2016;Bardei et al 2017;Almeida et al 2018) than in central European locations with mono-modal Cladosporium distributions (Chrenová et al 2004;Kasprzyk et al 2016;Sindt et al 2016), although Cladosporium incidence and seasonality are currently underreported.…”

“…and Cladosporium spp. and negative correlation with humidity (52). In this study, the greatest release of fungal aerosols occurred in the cold season while the minimum release occurred in the warm season, which is consistent with the results of studies by Pasquarella et al (2) and Niazi et al (14).…”

“…The authors attributed this result to increased wet deposition rates. In contrast, temperature was positively correlated with both Alternaria and Cladosporium spore levels measured over the course of two years in the atmosphere in the same study [48]. The day-to-day patterns are related to the phenology of the source communities, while diurnal fluctuations may better reflect physiological characteristics of the organisms and their tolerance to environmental stressors.…”
