Fig. 9. Specific dynamic action (SDA, in kJ) plotted against meal energy (kJ) for 11 species of lizards. The log plot was used for convenience in visualizing the range of data. On average, SDA was equivalent to 17.5% of meal energy. Numbers signify the following species and their meal type: 1, Sceloporus merriami – cricket meal (Beaupré et al., 1992); 2, Anolis carolinensis – beef meal (Coulson and Hernandez, 1983); 3, Sceloporus occidentalis – cricket meal (Roe et al., 2005); 4, Eulamprus tympanum – mealworm meal (Robert and Thompson, 2000); 5, Sphenomorphus indicus – mealworm meal (Hong-Liang et al., 2004); 6, Eumeces chinensis – frog meal (Pan et al., 2005); 7, Eumeces chinensis – mealworm meal (Pan et al., 2005);8, Eulamprus quoyii – mealworm meal (Iglesias et al., 2003); 9, Varanus exanthematicus – rodent meal (Hicks et al., 2000); 10, Tubinambis merianae – beef meal (Klein et al., 2006); 11, Varanus albigularis – egg meal (Secor and Phillips, 1997); 12, Varanus albigularis – turkey/snail meal (Secor and Phillips, 1997); 13, Varanus albigularis – rodent meal (Secor and Phillips, 1997).
