Microbiol."],"abstract":"<jats:p>Airborne dispersion of microorganisms is a constant ecologically significant global process. However, the initial stage of this process, the uplift of microbes to the atmosphere, remains poorly understood as an ecological filter. Differential aerosolization could serve as a potent selector allowing a subset of microorganisms to disperse via air more efficiently, providing potential advantages in establishment in new environments. While traits associated with atmospheric survival and deposition are well documented, microbial aerosolization is still generally presumed to be stochastic, primarily due to the small size of microorganisms and their lack of active biological ejection mechanisms like those found in seeds and larger fungal spores. However, emerging evidence suggests that uplift into the atmosphere is a dynamic interaction between physical forces in the environment and specific biological traits. This review synthesizes observations from genomic source tracking studies and laboratory experiments that describe how preferential enrichment of certain taxa into the atmosphere is based on intrinsic properties including extracellular polymeric substance (EPS) mediated aggregation, cell surface hydrophobicity, surfactant production, and other potentially relevant microbial traits. Additional candidate traits that may contribute to enhanced aerosolization are identified along with the potential mechanistic basis by which they might influence uplift. Future work with controlled chamber studies on single organisms and integration of atmospheric flux measurements with trait-based microbial uplift can provide a mechanistic basis for more accurate models of bioaerosol flux. Improving our comprehension of bioaerosol aerosolization behavior and flux is critical to understanding the dispersal of microorganisms across diverse habitats and their subsequent impacts on ecosystems, global climate, and the spread of diseases.<\/jats:p>","DOI":"10.3389\/fmicb.2026.1923366","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T14:21:29Z","timestamp":1787235689000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond survival: microbial dispersion via aerosolization as an evolutionary trait"],"prefix":"10.3389","volume":"17","author":[{"given":"Emily A.","family":"Kraus","sequence":"first","affiliation":[{"name":"Department of Environmental Engineering, University of Colorado Boulder","place":["Boulder, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Gillison","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biological Engineering, Colorado State University","place":["Fort Collins, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocio","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Department of Agricultural Biology, Colorado State University","place":["Fort Collins, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margot M.-F.","family":"Thomas-Gatel","sequence":"additional","affiliation":[{"name":"Department of Biology, Colorado State University Pueblo","place":["Pueblo, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sam","family":"Golon","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology, and Pathology, Colorado State University","place":["Fort Collins, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolyn R.","family":"Cornell","sequence":"additional","affiliation":[{"name":"Department of Agricultural Biology, Colorado State University","place":["Fort Collins, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane E.","family":"Stewart","sequence":"additional","affiliation":[{"name":"Department of Agricultural Biology, Colorado State University","place":["Fort Collins, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amaya Garcia","family":"Costas","sequence":"additional","affiliation":[{"name":"Department of Biology, Colorado State University Pueblo","place":["Pueblo, CO, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen D.
