The correlation between aggression and courtship over the two salinity levels was highly significant (r Pearson = 0.58, df = 43, p < 0.001; Fig. 4 ).
The correlation between aggression and courtship over the two salinity levels was highly significant (r Pearson = 0.58, df = 43, p < 0.001; Fig. 4 ).
Moreover, over the entire data-set, there was only a marginally non-significant tendency for males to show higher levels of aggression and courtship in low, than high, salinity.
