“…The mating-related animal research provided some support for both of these hypotheses. The use of backup signals of quality was demonstrated, for instance, in Drosophila saltans where removing one courtship component (either visual, auditory, chemical or tactile) did not eliminate the female's decision to mate (Colyott, Odu, & Gleason, 2016). On the other hand, the study on peacock spiders (Maratus volans) showed that both visual and vibratory signalling is important for mating success supporting the multiple messages hypothesis (Girard, Elias, & Kasumovic, 2015).…”

“…Drosophila constitutes an ideal group of species for studying the role of multiple sensory signals on mate recognition and sexual isolation: their social and sexual interactions depend on vision, sound, olfaction and taste [13][14][15][16][17][18][19][20][21][22]. The courtship of Drosophila melanogaster flies consists of a series of stereotyped behaviours [23,24].…”

Sensory cues exchanged during courtship are crucial for mate choice: if they show intraspecific divergence, this may cause or reinforce sexual isolation between strains, ultimately leading to speciation. There is a strong asymmetric sexual isolation between Drosophila melanogaster females from Zimbabwe (Z) and males from all other populations (M). While M and Z flies of both sexes show different cuticular pheromones, this variation is only partly responsible for the intraspecific isolation effect. Male acoustic signals are also partly involved in sexual isolation. We examined strain-specific courtship behaviour sequences to determine which body parts and sensory appendages may be involved in sexual isolation. Using two strains representative of the Z- and M-types, we manipulated sensory cues and the social context; we then measured the consequence of these manipulations on courtship and copulation. Our data suggest that Z females mated best with males whose sensory characteristics matched those of Z males in both quantity and quality. M females were less choosy and much less influenced by the sensory and social contexts. Differences in emission and reception of sensory signals seen between Z and M flies may lead to the concerted evolution of multiple sensory channel, thereby shaping a population-specific mate recognition system.

“…In Drosophila, sexual isolation has been shown to evolve faster than postzygotic isolation (Coyne and Orr 1997), and PMPZ isolation faster than hybrid inviability but more slowly than sexual isolation (Turissini et al 2018). In this taxon, the male courtship cues, the acceptance threshold of females and/or the use of different sensory modalities in mate choice often vary between closely related interacting species (Gleason et al 2012;Giglio and Dyer 2013;Colyott et al 2016). Reinforcement of female discrimination against heterospecific males can induce changes in any of the above-mentioned traits, and it may also increase female discrimination toward conspecific males from other populations (Noor 1999;Hoskin et al 2005;Jaenike et al 2006;Bewick and Dyer 2014;Comeault et al 2016).…”

Strength of sexual and postmating prezygotic barriers varies between sympatric populations with different histories and species abundances

The impact of different reproductive barriers on species or population isolation may vary in different stages of speciation depending on evolutionary forces acting within species and through species’ interactions. Genetic incompatibilities between interacting species are expected to reinforce prezygotic barriers in sympatric populations and lead to cascade reinforcement between conspecific populations living within and outside the areas of sympatry. We tested these predictions and studied whether and how the strength and target of reinforcement between Drosophila montana and Drosophila flavomontana vary between sympatric populations with different histories and species abundances. All barriers between D. montana females and D. flavomontana males were nearly complete, while in the reciprocal cross strong postzygotic isolation was accompanied by prezygotic barriers whose strength varied according to population composition. Sexual isolation between D. flavomontana females and D. montana males was increased in long‐established sympatric populations, where D. flavomontana is abundant, while postmating prezygotic (PMPZ) barriers were stronger in populations where this species is a new invader and still rare and where female discrimination against heterospecific males was lower. Strengthening of sexual and PMPZ barriers in this cross also induced cascade reinforcement of respective barriers between D. flavomontana populations, which is a classic signature of reinforcement process.
