Life on the wind: Study reveals how microbes travel the Earth
Date:8/17/2011

Scientists from the UK and Switzerland have investigated the remarkable distance that microorganisms may be able to blow between continents, raising questions about their potential to colonise new lands and also potentially to spread diseases.

The researchers from Liverpool John Moores University (LJMU), Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) and the Ecole Polytechnique Fdrale de Lausanne (EPFL) the University of Neuchtel published their results in the Journal of Biogeography this month. They used large computer models of the Earth's atmosphere to study how widely microbes could be dispersed.

LJMU's Dr Dave Wilkinson led the team along with Symeon Koumoutsaris, from the International Space Science Institute in Bern, who modified computer models which were designed for studying the dispersal of dust particles. They looked at what would happen if they released virtual microbes from both the southern tip of South America and also from Mexico. Once airborne, microbes of 0.02mm in diameter and below can easily travel thousands of kilometres.

Dr Dave Wilkinson, LJMU School of Natural Science and Psychology, explained:

"Microbes less than 0.009 mm across went as far as Australia! These sizes would include microbes such as bacteria and many amoebae and also some fungal spores. We found that for smaller microbes, once airborne, dispersal is remarkably successful over a 1-year period. The most striking results are the extensive within-hemisphere distribution of small virtual microbes and the lack of dispersal between the Northern and Southern Hemispheres during the year-long time-scale of our simulations.

What our models show is that only the smallest microbes travel easily between continents. The larger ones (i.e. Larger than 20m but still 500 times smaller than the 1mm threshold previously believed to separate the "cosmopolitan organisms" from those with potential biogeographies) cannot
