“…We analysed female morph frequencies from the literature in seven I. graellsii populations from Iberia (Andrés et al, 2000;Sánchez-Guillén et al, 2005), five I. elegans populations from eastern Europe (Gosden, 2008), four I. senegalensis populations from Japan (Takahashi and Watanable, 2009), four I. fluviatilis populations from Uruguay (Mckee et al, 2005), four I. damula (Johnson, 1964), three I. ramburii (Robertson, 1985;Sirot et al, 2003) and two I. denticollis (Fincke et al, 2005;Có rdoba-Aguilar, 1993) populations from north America (Tables 1 and 2). …”

The influence of stochastic and selective forces in the population divergence of female colour polymorphism in damselflies of the genus Ischnura

Disentangling the relative importance and potential interactions of selection and genetic drift in driving phenotypic divergence of species is a classical research topic in population genetics and evolutionary biology. Here, we evaluate the role of stochastic and selective forces on population divergence of a colour polymorphism in seven damselfly species of the genus Ischnura, with a particular focus on I. elegans and I. graellsii. Colour-morph frequencies in Spanish I. elegans populations varied greatly, even at a local scale, whereas more similar frequencies were found among populations in eastern Europe. In contrast, I. graellsii and the other five Ischnura species showed little variation in colour-morph frequencies between populations. F ST -outlier analyses revealed that the colour locus deviated strongly from neutral expectations in Spanish populations of I. elegans, contrasting the pattern found in eastern European populations, and in I. graellsii, where no such discrepancy between morph divergence and neutral divergence could be detected. This suggests that divergent selection has been operating on the colour locus in Spanish populations of I. elegans, whereas processes such as genetic drift, possibly in combination with other forms of selection (such as negative frequency-dependent selection), appear to have been present in other regions, such as eastern Europe. Overall, the results indicate that both selective and stochastic processes operate on these colour polymorphisms, and suggest that the relative importance of factors varies between geographical regions.

“…However, the female's willingness to accept or reject male mating attempts will determine whether the male is successful (e.g. Van Gossum et al 2001a;Sirot et al 2003). Interestingly, mature female morphs of Ischnura elegans have been shown to differ in resistance and tolerance to male mating attempts (Gosden and Svensson 2007).…”

Differences in Mating Propensity Between Immature Female Color Morphs in the Damselfly Ischnura elegans (Insecta: Odonata)

Female-limited color polymorphisms occur in a variety of animal taxa where excessive male sexual harassment may explain the coexistence of multiple female color morphs. In the color polymorphic damselfly Ischnura elegans, mature and immature female color morphs coexist at the mating site where males are in search for suitable mating partners. Here, we study male preference and female mating propensity for the two immature female morphs. As would be expected, compared to mature morphs, both immature female morphs mate much less. Within immature females, one morph consistently mates more frequently compared to the other morph, a pattern that is similar for the ontogenetically corresponding mature female morphs. Preference experiments with the two differently colored immature female morphs, however, did not indicate male mate preference for either morph. Low mating frequencies of immature females at natural sites in combination with relatively high attractiveness of immature models in terms of male preference indicate that female behavior influences female mating success.

“…Female-limited polymorphisms are found in many species of damselflies (Cordero, 1992;Fincke, 1994;Andrés & Cordero Rivera, 2001;Wong et al, 2003;Sirot et al, 2003), dragonflies (Corbet, 1999), and butterflies, as well as some species of birds (Bleiweiss, 1992;Roulin et al, 2003). Species of damselfly with female-limited colour polymorphism usually have one morph that resembles a male, so-called Androchrome females (Corbet, 1999).…”

Phenotypic and genetic variation in emergence and development time of a trimorphic damselfly

Although colour polymorphisms in adult organisms of many taxa are often adaptive in the context of sexual selection or predation, genetic correlations between colour and other phenotypic traits expressed early in ontogeny could also play an important role in polymorphic systems. We studied phenotypic and genetic variation in development time among female colour morphs in the polymorphic damselfly Ischnura elegans in the field and by raising larvae in a common laboratory environment. In the field, the three different female morphs emerged at different times. Among laboratory-raised families, we found evidence of a significant correlation between maternal morph and larval development time in both sexes. This suggests that the phenotypic correlation between morph and emergence time in the field has a parallel in a genetic correlation between maternal colour and offspring development time. Maternal colour morph frequencies could thus potentially change as correlated responses to selection on larval emergence dates. The similar genetic correlation in male offspring suggests that sex-limitation in this system is incomplete, which may lead to an ontogenetic sexual conflict between selection for early male emergence (protandry) and emergence times associated with maternal morph.
