Intraspecific Variation in Maximum Ingested Food Size and Body Mass in Varecia rubra and Propithecus coquereli

Table 2

Least-squares regressions of log maximum ingested food size (V_b) against log last recorded (M_L), mean (M_X), and maximum (M_M) body mass. Note that only the interspecific regressions of all the strepsirrhine taxa are significant, while none of the intraspecific regressions (within P. coquereli and V. rubra) are significant (at alpha of 0.05).
