Table 2 Effects of paternity on male share of defense against territory competitors and brood predators. Maternal brood size and the size difference between females and males were included as additional factors that may affect male share of defense and/or male paternity share (see Methods). Significant intercept terms indicate non-egalitarian defense behaviors between males and females (note that parameter estimates are on the scale of the logit-link function). (a) Results for the model fit to intrusion pressure from territory competitors. (b) Results for the model fit to intrusion pressure from brood predators. Significant p-values (p < 0.05)  are in bold
