“…The possibility also remains that rainfall in tandem with wind direction leads to the monitoring observations made at the site. Alternaria and Cladosporium levels correlated significantly with mean temperature at both sites; this behaviour has been observed previously (Rodríguez-Rajo et al 2005) (Table 3). Moreover, mean temperature was shown by the MRT analyses to be the major variable influencing Alternaria spore concentration for both the Irish and English sites with a threshold of 15°C for Cork and 16°C at Worcester (Fig.…”

This study represents the first international intercomparison of fungal spore observations since 1990, focusing on atmospheric concentrations of Alternaria, Cladosporium, Ganoderma and Didymella spores. The campaigns were performed at sites located in Cork (Ireland) and Worcester (England) during summer 2010. Observations were made using Hirsttype volumetric spore traps and corresponding optical identification at the genus level by microscope. The measurements at both sites (including meteorological parameters) were compared and contrasted. The relationships between the fungal spore concentrations with selected meteorological parameters were investigated using statistical methods and multivariate regression trees (MRT). The results showed high correlations between the two sites with respect to daily variations. Statistically significant higher spore concentrations for Alternaria, Cladosporium and Ganoderma were monitored at the Worcester site. This result was most likely due to the differences in precipitation and local fungal spore sources at the two sites. Alternaria and Cladosporium reached their maxima a month earlier in Cork than in Worcester, and Didymella with Ganoderma peaked simultaneously with similar diurnal trends found for all the investigated spore types. MRT analysis helped to determine threshold values of the meteorological parameters that exerted most influence on the presence of spores: they were found to vary at the two sites. Our results suggest that the aeromycological profile is quite uniform over the British Isles, but a description of bioaerosols with respect to overall load and daily concentration can be quite diverse although the geographical difference between sites is relatively small. These variations in the concentrations therefore need to be explored at the national level.

“…However, we cannot underestimate the influence exerted by the local bioclimatic conditions of the inoculum source in the atmospheric representation of both types. Likewise, some authors have noted as the continentally index increased C. cladosporioides spore concentrations rose whereas C. herbarum concentrations increased with increasing height above sea level (Rodríguez-Rajo et al, 2005). Nonetheless, this hypothesis is not true for all sampling stations included in our study.…”

“…The abundance of Alternaria and Cladosporium spp. in the air has also been reported to vary with different bioclimatic conditions (Rodriguez-Rajo et al, 2005). In a study of the abundance of viable spores of the plant pathogenic fungus Gibberella zeae at 60 m above the ground, more viable spores were detected under cloudy conditions than under clear conditions, but fewer were found during rainfall (MaldonadoRamirez et al, 2005) presumably because they were washed out.…”

Abstract. For the past 200 years, the field of aerobiology has explored the abundance, diversity, survival and transport of micro-organisms in the atmosphere. Micro-organisms have been explored as passive and severely stressed riders of atmospheric transport systems. Recently, an interest in the active roles of these micro-organisms has emerged along with proposals that the atmosphere is a global biome for microbial metabolic activity and perhaps even multiplication. As part of a series of papers on the sources, distribution and roles in atmospheric processes of biological particles in the atmosphere, here we describe the pertinence of questions relating to the potential roles that air-borne micro-organisms might play in meteorological phenomena. For the upcoming era of research on the role of air-borne micro-organisms in meteorological phenomena, one important challenge is to go beyond descriptions of abundance of micro-organisms in the atmosphere toward an understanding of their dynamics in terms of both biological and physico-chemical properties and of the relevant transport processes at different scales. Another challenge is to develop this understanding under contexts pertinent to their potential role in processes related to atmospheric chemistry, the formation of clouds, precipitation and radiative forcing. This will require truly interdisciplinary approaches involving collaborators from the biological and physical sciences, from disciplines as disparate as agronomy, microbial genetics and atmosphere physics, for example.
