| Description
| - Případy koexistujících sexuálních a asexuálních příbuzných jsou hádankou, protože evoluční teorie předpokládá, že soutěž o stejnou ekologickou niku by vedla k vyloučení jedné či druhé skupiny. U cyklicky partenogenní mšice Rhopalosiphum padi se sexuální a fakultativně asexuální linie mísí v prostoru v období sexuální reprodukce. V tomto článku jsme zkoumali, jak vzájemné působení rozmnožovacího způsobu a prostředí může vest k časovému rozdělení nik. (cs)
- Cases of coexisting sexual and asexual relatives are puzzling, as evolutionary theory predicts that competition for the same ecological niches should lead to the exclusion of one or the other population. In the cyclically parthenogenetic aphid, Rhopalosiphum padi, sexual and facultative asexual lineages are admixed in space at the time of sexual reproduction. We investigated how the interaction of reproductive mode and environment can lead to temporal niche differentiation. We demonstrated theoretically that differential sensitivity of sexual and facultatively asexual aphids to an environmental parameter (mating host suitability) shapes the two strategies: whereas the sexual lineages switch earlier to the production of sexual forms, the facultative asexual lineages delay and spread out their investment in sexual reproduction. This predicted pattern of niche specialization is in agreement with the temporal structure revealed in natura by demographic and genetic data.
