1Data rank transformed. Raw means presented. 2May 1995 results used as a covariate for postburn comparisons due to the potential for pre-treatment effects (). Postburn results are covariate-adjusted means. 3Treatment time interaction (). Means followed by the same letter within years are not different (). 4Limited captures (20 individuals) of this species precluded statistical comparisons. 5Data square-root transformed. Raw means presented.
