“…This adds to previous evidence that the quantitative genetic architecture of trait divergence can be similar (Cresko et al. , 2004; Kennington & Hoffmann, 2010) or different (Armbruster et al. , 1997; Gilchrist & Partridge, 1999) within a given system, and depends on the environment where the phenotype is expressed (e.g.…”

Knowledge on the relative contribution of direct genetic, maternal and environmental effects to adaptive divergence is important for understanding the drivers of biological diversification. The moor frog (Rana arvalis) shows adaptive divergence in embryonic and larval fitness traits along an acidification gradient in south‐western Sweden. To understand the quantitative genetic basis of this divergence, we performed reciprocal crosses between three divergent population pairs and reared embryos and larvae at acid and neutral pH in the laboratory. Divergence in embryonic acid tolerance (survival) was mainly determined by maternal effects, whereas the relative contributions of maternal, additive and nonadditive genetic effects in larval life‐history traits differed between traits, population pairs and rearing environments. These results emphasize the need to investigate the quantitative genetic basis of adaptive divergence in multiple populations and traits, as well as different environments. We discuss the implications of our findings for maintenance of local adaptation in the context of migrant and hybrid fitness.

“…However, for much of the large literature on genetic architecture of divergence between natural populations (e.g. Gilchrist & Partridge, ; Fenster & Galloway, ; Demuth & Wade, ; Wegner et al ., ; Kennington & Hoffmann, ; Pritchard et al ., ), the ancestral state and the selection forces driving the divergence remain poorly known. Furthermore, genetic architecture is often sensitive to the environmental conditions during assay (Blows & Sokolowski, ; Demuth & Wade, ; van Heerwaarden & Sgro, ; Bubliy et al ., ).…”

Based on ecological and metabolic arguments, some authors predict that adaptation to novel, harsh environments should involve alleles showing negative (diminishing return) epistasis and/or that it should be mediated in part by evolution of maternal effects. Although the first prediction has been supported in microbes, there has been little experimental support for either prediction in multicellular eukaryotes. Here we use a line-cross design to study the genetic architecture of adaptation to chronic larval malnutrition in a population of Drosophila melanogaster that evolved on an extremely nutrient-poor larval food for 84 generations. We assayed three fitness-related traits (developmental rate, adult female weight and egg-to-adult viability) under the malnutrition conditions in 14 crosses between this selected population and a nonadapted control population originally derived from the same base population. All traits showed a pattern of negative epistasis between alleles improving performance under malnutrition. Furthermore, evolutionary changes in maternal traits accounted for half of the 68% increase in viability and for the whole of 8% reduction in adult female body weight in the selected population (relative to unselected controls). These results thus support both of the above predictions and point to the importance of nonadditive effects in adaptive microevolution.

“…Most studies on clines in different ectoderms including Drosophila were carried out to improve our understanding of local adaptation to environments (Kennington & Hoffmann, 2010) and most of these studies were based on latitudinal rather than altitudinal transects. Thus, in this study, we aimed to determine the altitudinal clines in body size, cold tolerance, resistance to starvation and desiccation in natural populations of the sibling species D. melanogaster and D. simulans.…”

http://www.eje.cz altitudinal transects (Bubliy & Loeschcke, 2005). Even so, they show similar environmental patterns especially in climatic factors like temperature. In this way, altitudes are thought to mirror latitudes (Klepsatel et al., 2014) and thus similar clinal patterns are expected along altitudinal transects. Besides these differences and similarities, altitudinal transects occur over relatively short geographical scales, which may allow a relatively high gene fl ow between locations compared to latitudes and provide an opportunity to test the possibility of local adaptation in spite of gene fl ow (Keller et al., 2013).Drosophila melanogaster is a cosmopolitan species, which originated from sub-Saharan Africa and colonized Eurasia, America and Australia (David & Capy, 1988) and is the main organism used for investigating the adaptive basis of clines (Fabian et al., 2015). Drosophila, especially Drosophila melanogaster, are well studied in terms of latitudinal variation in traits including body size, abdominal pigmentation, ovariole number, resistance to starvation and desiccation, tolerance of heat and cold etc.
