dc.description.abstract | There have been many potential explanations put forward as to why polyandry often persists despite the multiple costs it can inflict
on females. One such explanation is avoidance of costs associated with mating with genetically incompatible males. Genetic incompatibility
can be thought of as a spectrum from individuals that are genetically too similar (inbreeding) to those that are too dissimilar
(outbreeding or hybridization). Here we look for evidence that the level of outbreeding influences the benefits of polyandry in the seed
bug Lygaeus equestris. Our system allows us to test for benefits of polyandry at levels of genetic similarity ranging from full siblings
to heterospecifics, both in terms of egg production and hatching success. We found that while outbreeding level appeared to have no
effect on fitness for intraspecific matings, and polyandry did not appear to result in any increase in fertility or fecundity, hybridization
with a closely related species, Lygaeus simulans, carried considerable fitness costs. However, these costs could be rescued with a
single mating to a conspecific. Thus, polyandry may be beneficial in populations that co-occur with closely related species and where
there is reproductive interference. However, within-species genetic incompatibility is unlikely to be the driving force behind polyandry
in this species. Furthermore, the mechanism underlying this rescue of fertility remains unclear as manipulation of male cuticular hydrocarbon
profile, a possible mechanism by which females can assess male identity, had no effect on female offspring production. | |
