… and hypotheses from evolutionary biology ('immunocompetence-handicap hypothesis', 'good-genes hypothesis', 'compatible-genes hypothesis, and 'sex-allocation theory'), and with respect to possible influences of environmental factors on the immune system.

A test of the effects of androgens on immunity: no relationship between 11-keto testosterone and immune performance in bluegill sunfish (Lepomis macrochirus)
… effects of androgens are a key component of the immunocompetence handicap hypothesis (ICHH). My thesis uses bluegill sunfish (Lepomis macrochirus) to test two predictions arising from this hypothesis: (1) natural concentrations of the androgen 11-keto testosterone (11-KT) will be negatively …

Inbreeding, immunity and male sexual signaling in the black field cricket Teleogryllus commodus
… on the role of immunity in sexual selection. The immunocompetence handicap hypothesis (ICHH) proposes that sexual signals reliably indicate male immunocompetence because of a trade off between sexual trait expression and immunity. I first tested for the predicted trade off between male sexual …
