Results of statistical analyses of the effects of egg number (cluster size) on rates of water uptake of snake eggs (as measured by changes in egg mass through time during incubation). (The significance of the effects from each main factor in the repeated-measures ANOVA plus the interaction terms are shown. (a) The results based on the inclusion of all cluster size categories and (b) those based on a dataset excluding the smallest (and most divergent) cluster size (=four to five eggs). Cases where p<0.05 are shown in italics.)
