Results of linear models exploring the influence of sex, status and behaviour on brain arginine vasotocin (AVT) and isotocin (IT) concentrations in Neolamprologus pulcher. (Two-way interaction terms were included in the original models, but none were significant (α=0.05), and so these were dropped from the final models presented here. Values in italics indicate non-significant trends (0.1<p>0.05). Values in bold-italics indicate model terms that significantly contribute to significant models (p<0.05).)
