Kruskal–Wallis analysis of variance testing the effects of temperature (10, 15 and 20°C) on the proportion of abnormally developing embryos reared at the different pressures for different incubation periods. (H statistic (degrees of freedom, N=number of replicates); ^*for temperatures: 5, 10, 15, 20 and 25°C.)
