Drivers of soil biodiversity vary with organism type along an extensive aridity gradient

Soils harbor a diverse range of biodiversity, including microbes and soil animals, which are crucial in supporting ecosystem functions. Despite the well-known effects of biotic and abiotic factors on soil biodiversity, their relative importance on different soil organisms remains less known, reducing our ability to maintain multiple soil communities under environmental changes. We sampled 150 sites from humid to arid areas in eastern Australia...
