      abstract     = {Biological soil crusts (biocrusts) occur widely in the
                      uppermost millimeters of the soil in arid and semi-arid
                      systems. Worldwide they cover large terrestrial areas and
                      play a major role in the global terrestrial carbon and
                      nitrogen cycles. However, knowledge of the microbial
                      decomposer foodwebs within biocrusts is particularly scarce.
                      Heterotrophic protists in soil are predominantly
                      bacterivores, and because of their high biomass compared
                      with other soil fauna and fast turnover rates, protists are
                      considered an important factor for soil nutrient cycling and
                      energy fluxes. Thus, knowledge of their biodiversity,
                      abundance and functional roles is important to understand
                      soil ecosystem functions. We investigated the diversity and
                      abundance of heterotrophic soil protists in different types
                      of biocrusts from the Succulent Karoo, South Africa. With an
                      overall diversity of 23 distinct morphotypes, soil protist
                      biodiversity was shown to be high. The most abundant groups
                      were Spumella-like chrysomonads, gliding bodonids,
                      glissomonads and heteroloboseans. Protist abundance was
                      highly variable among samples. The abundance and diversity
                      did not differ significantly among different types of
                      biocrusts, indicating that microscale differences, but not
                      macroscopic soil crust builders (e.g. cyanobacteria, lichens
                      and bryophytes), have a major impact on the protist
                      community.},
