TABLE 1. Experimental parameters, the number of burrows produced in each experiment, and the distribution of burrow architecture among experiments. Terrarium size is in gallons. Sediment moisture values are in percent total volume. Duration is in days. Burrow architectures: IC = isolated chamber; VS = vertical shaft with terminal chamber; SS = subvertical shaft with terminal chamber. (All six tables presented in one PDF file.)
TABLE 2. Quantitative measurements of vertical shafts . All measurements in cm or degrees (slope only). SH# = Scaphiopus holbrookii burrow cast identification number. Sediment: O = 100% organic coconut fiber; LOS = layered 100% organic coconut fiber and sand; MOS = homogenized mixture of 100% organic coconut fiber and sand. (All six tables presented in one PDF file.)
TABLE 3. Quantitative measurements of subvertical shafts . Refer to Table 2 caption for legend. (All six tables presented in one PDF file.)
TABLE 4. Quantitative measurements of isolated chambers . Refer to Table 2 caption for legend. (All six tables presented in one PDF file.)
TABLE 5. Width and height of each toad compared to mean width and height values of the terminal chambers produced by each toad. All measurements are in cm. (All six tables presented in one PDF file.)
TABLE 6. Properties of dwelling traces (VS and SS) and a single resting trace (SHT16). Burrow architectures: VS = vertical shaft with terminal chamber; SS = subvertical shaft with terminal chamber; RT = resting trace. (All six tables presented in one PDF file.)
