Elevational Distribution of Flightless Ground Beetles in the Tropical Rainforests of North-Eastern Australia.

Controlling for the influence of subregional differences, generalised linear mixed models showed that elevation was significantly and positively related to species richness (estimated coefficient = 0.75, standard error = 0.20, t value = 3.72, P = 0.0002, n = 69) and, albeit marginally significant, abundance (estimated coefficient = 1.16, standard error = 0.66, t value = 1.83, P = 0.067, n = 69).

The impact of treefall was, however, highly significant when using the information theory ( Table 2 ) which tested models using combinations of different variables.
