Impacts of microbial aerosols on natural and agro-ecosystems: Immigration, invasions, and their consequences

Abstract : In order for the traits associated with aerial dissemination to be positively selected through evolution, microorganisms that survive atmospheric transport must multiply in some habitat that they have accessed via this transport. Surprisingly little is known about the rates of successful colonization of new-found habitats by the diverse range of microorganisms in the atmosphere. Most examples come from studies of the microbial ecology of extreme oligotrophic habitats with low microbial loads or of the epidemiology of plant diseases caused by very host-specific pathogens. The patterns that emerge from these studies suggest that successful colonization of new-found habitats depends on the interplay of resource availability, the weight of microbial competition, and the specialization of microorganisms to very particular niches. We suggest new experimental approaches to further elucidate the frequency of habitat colonization and invasion by microorganisms traveling in the atmosphere.
