The species spectrum of soil myxobacteria in relation to soil-forming factors, particularly soil reaction

Ruckert, G.

The average species composition of the myxobacteria in 9 series of soil samples is described. A total of 444 soil samples was examined, and each series or sub-series consisted of more than 20 samples. Soils of tropical rainforests were particularly rich in species. The primitive soils of the sub-Arctic tundra were particularly poor in species, and contained fewer than did arid and extremely arid desert soils.
