A new genus (Darbyshirella) of giant amoebae has been isolated from Scottish soil and elsewhere as described by Berney et al. (2015) Protist 166,291-296. The significance of these amoebae in soil ecology remains to be determined. Dr Darbyshire continues to research protozoa in the rhizosphere and on the root surface; recent videos of his work can be viewed on the Institute's YouTube channel.
