Immune measures
The full models for all immune measures (circulation hemocytes, presence
of circulating microaggregations, and zones of antibacterial activity)
included diet type, infection cue, and the interaction between the two
(main effects) as well as the average amount of diet eaten and pronotum
width (covariates). Circulating hemocytes were analyzed with a negative
binomial generalized linear model, the presence of circulating
microaggregations of hemocytes was analyzed using a generalized linear
model with a binomial distribution, and the zones of antibacterial
activity were analyzed with a generalized linear model with a Gamma
error distribution.
