Recombination, chromosome number and eusociality in the Hymenoptera
Extraordinarily high rates of recombination have been observed in some eusocial species. The most popular explanation is that increased recombination increases genetic variation among workers, which in turn increases colony performance, for example by increasing parasite resistance. However, support for the generality of higher recombination rates among eusocial organisms remains weak, due to l...
متن کاملSimultaneous Analysis and the Origin of Eusociality in the Vespidae (Insecta: Hymenoptera)
A review of the literature concerning the phylogenetics of the Vespidae is presented. We also present a new phylogenetic analysis of the Vespidae based on what is by far the largest taxon sample to include molecular data, and the largest phenotypic character dataset ever compiled. Relationships among the subfamilies are Euparagiinae + (Masarinae + (Eumeninae + (Stenogastrinae + (Polistinae + Ve...
متن کاملChromosome Number Variation in Iranian Populations of Acorus calamus
Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...
متن کاملChemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of sociality. However, because chemoreceptor repertoires have been characterized in few social insects and their solitary relatives, a comprehensive exam...
متن کاملColony Size Evolution and the Origin of Eusociality in Corbiculate Bees (Hymenoptera: Apinae)
Recently, it has been proposed that the one of the main determinants of complex societies in Hymenoptera is colony size, since the existence of large colonies reduces the direct reproductive success of an average individual, given a decreased chance of being part of the reproductive caste. In this study, we evaluate colony size evolution in corbiculate bees and their relationship with the socia...
