What's on your boots : An investigation into the role we play in protist dispersal
D. M. Wilkinson (2010, Journal of Biogeography, 37, 393-397) suggested that anthropogenic dispersal is an understudied and potentially important factor in terrestrial protist biogeography. We investigated human footwear as a potential vector of dictyostelids, a diverse group of amoebae that includes both geographically restricted and cosmopolitan species. Eighteen pairs of boots were examined and
