“…An alternative explanation for the disparity between the within-and between-population studies may be the greater range in phenotypes amongst the crosses between two populations, compared with withinpopulation variation. Colorado flies are different from those from Vancouver, in both their songs and pheromones (Klappert et al, 2007;Routtu et al, 2007;Jennings et al, 2014a), despite coming from the same phylogeographic clade.…”

“…Our results are broadly suggestive of polygenic determination for intrapopulation phenotypic variation, though some individual chromosomes explained more phenotypic variation than others, in a population-specific manner. Song and CHCs contribute to mating success in D. montana, and CHCs are probably also involved in ecological adaptation (Veltsos et al, 2012;Jennings et al, 2014a). Heritabilities were sometimes low (Table 1), which may well have militated against our ability to detect QTL (the only suggestive QTL found was for a song trait with one of the highest heritabilities, CN in Oulanka).…”

“…PCs of CHC data were obtained from both sexes simultaneously because they are only moderately sexually dimorphic in D. montana, with no sex-specific compounds (Veltsos et al, 2012;Jennings et al, 2014a). The PCA was on relative proportions of log-transformed CHCs (Rundle et al, 2009) and used 18 compounds in total.…”

“…Various song components influence mating latency and courtship duration (Veltsos et al, 2012), and populations differ in both song and preference (Klappert et al, 2007;Ritchie et al, 2007). Recent studies of cuticular hydrocarbons (CHCs) in D. montana show that they influence mating decisions independently of song and also differ between populations (Veltsos et al, 2012;Jennings et al, 2014a).…”

The genetic architecture of sexually selected traits in two natural populations of Drosophila montana

et al. 2015

We investigated the genetic architecture of courtship song and cuticular hydrocarbon traits in two phygenetically distinct populations of Drosophila montana. To study natural variation in these two important traits, we analysed within-population crosses among individuals sampled from the wild. Hence, the genetic variation analysed should represent that available for natural and sexual selection to act upon. In contrast to previous between-population crosses in this species, no major quantitative trait loci (QTLs) were detected, perhaps because the between-population QTLs were due to fixed differences between the populations. Partitioning the trait variation to chromosomes suggested a broadly polygenic genetic architecture of within-population variation, although some chromosomes explained more variation in one population compared with the other. Studies of natural variation provide an important contrast to crosses between species or divergent lines, but our analysis highlights recent concerns that segregating variation within populations for important quantitative ecological traits may largely consist of small effect alleles, difficult to detect with studies of moderate power.

“…As a result of their species-specificity, CHCs are widely used for identification of sibling or cryptic species (Kather and Martin 2012). Recent studies on CHC profiles of drosophilid (Jennings et al 2014) and tephritid flies (Vaníčková 2012, Vaníčková et al 2015) evaluated the use of CHCs in delineating groups within supposedly cryptic taxa. An initial analysis included one population each of the three morphospecies within the FAR complex and Ceratitis capitata as a comparative taxon (Vaníčková 2012, Vaníčková et al 2014).…”

An integrative approach to unravel the Ceratitis FAR (Diptera, Tephritidae) cryptic species complex: a review

This paper reviews all information gathered from different disciplines and studies to resolve the species status within the Ceratitis FAR (Ceratitis fasciventris, Ceratitis anonae, Ceratitis rosa) complex, a group of polyphagous fruit fly pest species (Diptera, Tephritidae) from Africa. It includes information on larval and adult morphology, wing morphometrics, cuticular hydrocarbons, pheromones, microsatellites, developmental physiology and geographic distribution. The general consensus is that the FAR complex comprises Ceratitis anonae, two species within Ceratitis rosa (so-called R1 and R2) and two putatitve species under Ceratitis fasciventris. The information regarding the latter is, however, too limited to draw final conclusions on specific status. Evidence for this recognition is discussed with reference to publications providing further details.

Transgenerational effects in offspring of chronically irradiated populations of Drosophila melanogaster after the Chernobyl accident

The zone of the Chernobyl nuclear disaster represents the largest area of chronic low-intensity radioactive impact on the natural ecosystems. The effects of chronic low-dose irradiation for natural populations of organisms and their offspring are unknown. The natural populations of Drosophila melanogaster sampled in 2007 in Chernobyl sites with different levels of radiation contamination were investigated.
