'Ballooning' spiders grounded by infection

Money spiders infected with Rickettsia bacteria are less likely to 'balloon' - that is, to use their silk as sails to catch gusts of wind and travel long distances. Researchers writing in the open access journal BMC Biology suggest that it may be in the bacteria's interests to ground the spiders and that this reduction in dispersal could reduce gene flow and impact on reproductive isolation within the meta-population.
