Immunoecology of species with alternative reproductive tactics and strategies

BioRxiv : the Preprint Server for Biology

Abstract

Alternative reproductive tactics and strategies (ARTS) refer to polymorphic reproductive behaviours in which in addition to the usual two sexes, there are one or more alternative morphs, usually male, that have evolved the ability to circumvent direct intra-sexual competition. These additional morphs have unique morphological, ecological, developmental, behavioural, life-history, and physiological profiles that shift the balance between self-maintenance, one aspect being immunity, and reproduction. Here, we review the immunoecological work on species with ARTS. We first summarize the evolution, development and maintenance of ARTS. We then review the main immunoecological hypotheses relevant to species with ARTS, dividing them into physiological, life-history, and ecological hypotheses. In context of these hypotheses, we critically review in detail all immunoecological studies we could find on species with ARTS. Several interesting patterns emerge. Generally, progress would be faster if hypotheses and predictions were always explicitly articulated. Oddly, there is a paucity of studies on insects, despite the many benefits that arise from working with insects: larger sample sizes, simple immune systems, and countless forms of alt...Continue Reading
