Table 2. Variables that were used in the full hatching success model, and their definitions. * = interaction term.

Variable type	Variable	Definition
Fixed effects	Production pH, Production Temperature2,Prod pH * Prod Temp2	Does production environment affect egg hatching?
	Production pH * Time, Production Temp2 * Time	Does production environment affect egg hatching rate?
	Production pH *Day3 Production Temp2 * Day3	Does the effect of production environment change over time (acclimatization)?
	Hatching pH, Hatching Temperature2, Hatch pH * Hatch Temp2	Does hatching environment affect egg hatching?
	Hatch pH * Time, Hatch Temp2 * Time	Does hatching environment affect egg hatching rate?
	|ΔpH|, |Δtemp|2	Do differences in pH and temperature conditions between egg production and egg hatching environment affect hatching?
	|ΔpH|*Day3, |Δtemp|2*Day3	Does the effect of pH and temperature change between egg production and egg hatching environment differ between days?
Random effects	Day nested within levels of bottles(1|Bottle18/Day3)	Eggs that come from same bottle are more alike than other eggs, and eggs that come from same bottle on same day (divided into 2 Petri dishes) are even more alike.
	Repeated measures of same eggs counted over hatching time (Time|Petri_dish108)	Eggs on a Petri dish are counted several times, and thus are not independent replicates.

^{1, 2, 3, 18 & 108} = The number of factor levels.
