Figure 4 in Reproductive characteristics of Elaphe quadrivirgata (Serpentes: Colubridae) from ecologically dissimilar main island and island populations

Figure 4. Comparisons of (A) mean relative clutch mass (RCM) and (B) mean relative egg mass (REM) of Elaphe quadrivirgata between Shiga and Yakushima Island. RCM was calculated as clutch mass divided by post-ovipositional maternal body mass. REM was calculated as mean egg mass of a clutch divided by post-ovipositional maternal body mass. For snakes from Shiga, the right-hand column shows the subset of data which comprises snakes with an SVL range comparable to that of snakes from Yakushima. Vertical bars are 1 SD. Numerals above bars represent sample sizes.
