The Szybalski wedge plate technique has been used to map the responses of bacteria to up to 4 simultaneously varying environmental factors. 2‐dimensional NaCl‐pH gradient plates were used throughout. Sets of the latter were incubated at a range of temperatures to provide a third dimension. A fourth variable, nitrate concentration, was investigated by incorporating it homogeneously in sets of NaCl‐pH gradient plates.
