Table 3. Results of mixed model analysis of variance for sperm velocity and percentage of motile sperm (% motile) of A. planci sperm subjected to three different pH/pCO₂ conditions (factor pH).

			Velocity			% Motile
	DF	MS	F	p	MS	F	p
pH	2	0.0218	23.57	<0.0001	1.2600	23.86	<0.0001
Male	5	0.0381	41.23	<0.0001	0.4400	8.33	<0.0001
pH X M	10	0.0015	1.58	0.1558	0.0531	1.01	0.4588
Slide (pH X M)	34	0.0009	1.99	<0.0001	0.0528	8.32	<0.0001
Residual	232	0.0005			0.0063
Total	283

Sperm was derived from 6 separate males (Males). Slide is a random/nested factor representing measurements taken from three independent dilutions for each male x pH combination. Velocity data were log-transformed, motility data arcsine-square root-transformed for analysis.
