Mean proportional abundance of core mycobacteria community members.
Proportional abundance of mycobacteria detected in > 90% of soil and water samples using the genus specific and slow growing specific primers respectively. Groups are ordered from left to right by increasing mean proportional abundance.

The effect of environmental variables on the presence of slow growing mycobacteria.
NMDS ordination of slow growing mycobacterium water community’s highlighting the effect of each significant environmental variables upon the separation of the data points. GAM fitted isoclines represent predicted values for latitude and the size of each point represents the true value for this variable. A = mycobacteria communities in soil, B = slow growing mycobacteria in soil, C = mycobacteria in water, D = slow growing mycobacteria in water.

The relationship between elevation and mycobacteria abundance.
Linear regression of the proportional abundance of mycobacteria in water against elevation.

The effect of elevation on proportional abundance of soil mycobacteria.
Linear regression of the proportional abundance mycobacteria in soil against elevation.
