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.
