  1. Models were split into three different categories: (1) genetic models, investigating the effects of different TLR haplotypes and heterozygosity; (2) ecological & landscape model, investigating the landscape, sex, age, and host population density in interaction with sex ratio as factors; and (3) genetics & landscape models, combining genetic factors from the genetic models with landscape as a surrogate for ecological factors. The best model is shown in bold.
