Evolutionary trade-off between innate and acquired immune defences in birds

Table 1 The results of Bayesian phylogenetic mixed models testing associations between MHC gene copy number (acquired immunity) and haemagglutination (innate immunity) in birds

Predictor	Estimate	Lower 95% CL	Upper 95% CL	p
Intercept	1.395	0.975	1.811	< 0.001
Haemagglutination	− 0.042	− 0.080	− 0.003	0.033
Log body mass	− 0.237	− 0.407	− 0.065	0.007
Residual lifespan	0.258	− 0.170	0.687	0.241
Breeding latitude	0.007	0.000	0.013	0.057
Extent of migration	− 0.113	− 0.249	0.020	0.100

Coefficient estimates with corresponding 95% credibility limits (CL) and p-value are shown for each predictor; all values were averaged across 100 different phylogenies. Significant coefficients are marked in bold
