Life History Consequences of the Facultative Expression of a Dispersal Life Stage in the Phoretic Bulb Mite (Rhizoglyphus robini).

摘要: Life history traits play an important role in population dynamics and correlate, both positively negatively, with dispersal a wide range of taxa. Most invertebrate studies on trade-offs between life have focused via flight, yet much less is known about how influence species that disperse by other means. In this study, we identify effects investing morphology (dispersal expression) the male dimorphic bulb mite (Rhizoglyphus robini). This has facultative juvenile stage (deutonymph) during which individuals can phoresy. Further, adult males are either fighters (which kill mites) or benign scramblers. Here, experiment, investigate size at maturity, sex morph ratio, female lifetime reproductive success. We show correlate negatively expression stage. Remarkably, all expressed developed into competitive none suggests alternative, strategies should not be viewed isolation but considered concurrently.
