    Parallel effects of the inversion In(3R)Payne on body size across the North American and Australian clines in Drosophila melanogaster

    Kapun, M. ; Schmidt, C. ; Durmaz, E. ; Schmidt, P. S. ; Flatt, Thomas

    Chromosomal inversions are thought to play a major role in climatic adaptation. In D. melanogaster, the cosmopolitan inversion In(3R)Payne exhibits latitudinal clines on multiple continents. As many fitness traits show similar clines, it is tempting to hypothesize that In(3R)P underlies observed clinal patterns for some of these traits. In support of this idea, previous work in Australian...

    Spatially varying selection shapes life history clines among populations of Drosophila melanogaster from sub-Saharan Africa

    Fabian, D. K. ; Lack, J. B. ; Mathur, V. ; Schlötterer, C. ; Schmidt, P. S. ; Pool, J. E. ; Flatt, Thomas

    In: Journal of Evolutionary Biology, 2015, vol. 28, no. 4, p. 826–840

    Clines in life history traits, presumably driven by spatially varying selection, are widespread. Major latitudinal clines have been observed, for example, in Drosophila melanogaster, an ancestrally tropical insect from Africa that has colonized temperate habitats on multiple continents. Yet, how geographic factors other than latitude, such as altitude or longitude, affect life history in this...
