Significance of individual contrasts comparing different treatment combinations on morphometric characters

Contrast	Total body length	Snout-vent length	Tail length	Body width
Control vs ECO2	ns	ns	ns	ns
Control vs ETem32	0.0075	0.0488	0.0275	ns
Control vs ETem34	0.0022	< 0.0001	0.0089	0.0033
Control vs (ETem32, ETem34)	0.0022	0.0011	0.0087	0.0344
ETem32 vs ETem34	ns	0.0101	ns	0.0220
ECO2 vs ETem32	0.0436	Ns	ns	ns
ECO2 vs ETem34	0.0500	0.0016	ns	0.0321
ECO2 vs (ETem32, ETem34)	0.0227	0.0040	ns	0.0477

Significance of these contrasts was tested in repeated measures analyses of variance carried out using PROC MIXED in SAS for the whole experimental period. Contrasts involving ECO2 involved data during the initial 5 weeks after hatching. Contrasts involving the control and ETem34 involved data during the initial 11 weeks after hatching
