Likelihood-ratio tests and corresponding p-values derive from generalized linear models performed in JMP IN 7.0 (SAS Institute Inc., Carey, NC, USA). Non-significant interaction terms were removed from the final models. Developmental durations were log-transformed. Significant p-values are shown in bold
