Absence of reproduction-immunity trade-off in male Drosophila melanogaster evolving under differential sexual selection.

ABSTRACT: BACKGROUND:The theory of trade-off suggests that limited resources should lead to trade-off in resource intensive traits such as, immunity related and sexually selected traits in males. Alternatively, sexual exaggerations can also act as an honest indicator of underlying immunocompetence, leading to positive correlations between these traits. Evidences in support of either hypothesis in invertebrates are equivocal. Whereas several studies have addressed this question, few have used naturally occurring pathogens and realized post infection realized immunity (e.g., survivorship) to assay the fitness correlations between these two sets of traits. RESULTS:Adopting an experimental evolution approach, we evolved replicate populations of Drosophila melanogaster under high and low sexual selection
