ABSTRACT. Biological soil crusts are diverse assemblages of bacteria, cyanobacteria, algae, fungi, lichens, and mosses that cover much
of arid land soils. The objective of this study was to quantify protozoa associated with biological soil crusts and test the response of
protozoa to increased temperature and precipitation as is predicted by some global climate models. Protozoa were more abundant when
associated with cyanobacteria/lichen crusts than with cyanobacteria crusts alone. Amoebae, flagellates, and ciliates originating from the
