Fig. 5. Relationship between body mass and net cost of pedestrian (filled
triangles, NCOTp) and burrowing (filled circles, NCOTb)
transport for individual hopping mice, Notomys alexis. Unfilled
symbols are mean NCOTb measurements for a variety of burrowing
mammals taken from the literature (Vleck,
1979; Du Toit et al.,
1985; Lovegrove,
1989; Seymour et al.,
1998; Withers et al.,
2000). Regression line shows NCOTp for walkers and
runners derived from (Full et al.,
1990) and incorporates data from mammals, birds, reptiles,
amphibians, myriapods, crustaceans and insects.
