During sexual imprinting, offspring learn parental phenotypes and then select mates who are similar to their parents. Imprinting has been thought to contribute to the process of speciation in only a few rare cases; this is despite imprinting's potential to generate assortative mating and solve the problem of recombination in ecological speciation. If offspring imprint on parental traits under divergent selection, these traits will then be involved in both adaptation and mate preference. Such ‘magic traits’ easily generate sexual isolation and facilitate speciation. In this study, we show that imprinting occurs in two ecologically divergent stickleback species (benthics and limnetics: Gasterosteus spp.). Cross-fostered females preferred mates of their foster father's species. Furthermore, imprinting is essential for sexual isolation between species; isolation was reduced when females were raised without fathers. Daughters imprinted on father odour and colour during a critical period early in development. These traits have diverged between the species owing to differences in ecology. Therefore, we provide the first evidence that imprinting links ecological adaptation to sexual isolation between species. Our results suggest that imprinting may facilitate the evolution of sexual isolation during ecological speciation, may be especially important in cases of rapid diversification, and thus play an integral role in the generation of biodiversity.

Abstract The extent to which sexual selection is involved in speciation with gene flow remains an open question and the subject of much research. Here, we propose that some insight can be gained from considering the concept of magic traits (i.e., traits involved in both reproductive isolation and ecological divergence). Both magic traits and other, “non-magic”, traits can contribute to speciation via a number of specific mechanisms. We argue that many of these mechanisms are likely to differ widely in the extent to which they involve sexual selection. Furthermore, in some cases where sexual selection is present, it may be prone to inhibit rather than drive speciation. Finally, there are a priori reasons to believe that certain categories of traits are much more effective than others in driving speciation. The combination of these points suggests a classification of traits that may shed light on the broader role of sexual selection in speciation with gene flow. In particular, we suggest that sexual selection can act as a driver of speciation in some scenarios, but may play a negligible role in potentially common categories of magic traits, and may be likely to inhibit speciation in common categories of non-magic traits.

Rapid adaptive radiation poses two distinct questions apart from speciation and adaptation: What happens after one speciation event and how do some lineages continue speciating through a rapid burst? We review major features of rapid radiations and their mismatch with theoretical models and speciation mechanisms. The paradox is that the hallmark rapid burst pattern of adaptive radiation is contradicted by most speciation models, which predict continuously decelerating diversification and niche subdivision. Furthermore, it is unclear if and how speciation-promoting mechanisms such as magic traits, phenotype matching, and physical linkage of coadapted alleles promote rapid bursts of speciation. We review additional mechanisms beyond ecological opportunity to explain rapid radiations: ( a) ancient adaptive alleles and the transporter hypothesis, ( b) sexual signal complexity, ( c) fitness landscape connectivity, ( d) diversity begets diversity, and ( e) plasticity first. We propose new questions and predictions connecting microevolutionary processes to macroevolutionary patterns through the study of rapid radiations.

The article considers floristic vocabulary of Lina Kostenko poetry in the linguocultulorogical aspect; mythological semantics and symbolic of floristic names were determined in the poetry collection "Three hundred verses"; the link between symbolic meaning of flowers with totemic beliefs, between chthonic semantics of vegetation, solar myths were studied, peculiar traits of poetic arrangement were analyzed. Conclusions were drawn on the original poetic model of the mythic space that unites the worlds of heavens and the earth, rich in floristic images, enrooted in ancient totemic beliefs. The harmonic synergy of a man and the nature envisages the author's interpretation of universal floristic symbols in the limits of paradigm "flowers" – "myth" – "poet", wherein the flowers acquire symbolic meaning of the eternity of life born in the cosmogony depths of mythological archaic. In the poetry of Lina Kostenko an amazing unification of the internal world of a man with the realities of the world of nature takes place, the natural elements turn into cosmogony forces that create the renewed mythical space, wherein the flowers are the symbols of time, live signs of times of year, and the color symbolizes life milestones of the poetess herself. Archaic mythological symbolic as an integral part of poetic text obtains a new meaning due to which an ancient past unites with modern times, floristic names are transformed into universal poetic symbols, disclose figurative world of poetry. The origins of floristic symbolic are enrooted into vegetation totemism, when the people respected different types of flowers and animals as prime ancestors, bestowed them with magic traits, chthonic semantics, considered them amulets and used separate types of plants as medicines or bloodless sacrifices in the gods' cults. A particular type of solar-floristic metaphor can be considered as a revelation of totemism, built on the grounds of metonymy, the majority of "floristic" lexemes, used by Lina Kostenko, stand as names for typical Ukrainian decorative plants, but the author's poetic arrangement makes every floristic composition of the poetess unparalleled.
