Dynamics of Copy Number Variation in Host Races of the Pea Aphid
Ludovic Duvaux,Quentin Geissmann,Karim Gharbi,Jing-Jiang Zhou,Julia Ferrari,Carole M. Smadja,Roger K. Butlin +6 more
TL;DR: It is found that CNV was widespread in the global sample, with a significantly higher occurrence in multigene families, especially in Ors, and it was found that Gr were overrepresented among genes discriminating host races, as were CDD genes and pseudogenes.
Journal ArticleDOI
Inter- and Intrapopulation Effects of Sex and Age on Epicuticular Composition of Meadow Grasshopper, Chorthippus Parallelus
TL;DR: In this paper, the authors analyzed patterns of variation in cuticular lipids across and within five populations of the meadow grasshopper Chorthippus parallelus and revealed considerable differences between the sexes and between populations and differences in the pattern of sexual dimorphism between populations.
Journal ArticleDOI
Signals of demographic expansion in Drosophila virilis
TL;DR: The lack of geographic structure and the star-like topology depicted by the D. virilis haplotypes indicate a pattern of global demographic expansion, probably related to human movements, although this interpretation cannot be distinguished from a selective sweep in the mitochondrial DNA until nuclear sequence data become available.
Journal ArticleDOI
Does runaway sexual selection work in finite populations
TL;DR: It is suggested that assortative mating is inefficient at generating correlations, especially if sexual selection maintains characters away from their viability optimum, and in finite populations, such weak correlations will be overwhelmed by drift.
Journal ArticleDOI
Phylogenomics of the adaptive radiation of Triturus newts supports gradual ecological niche expansion towards an incrementally aquatic lifestyle.
TL;DR: The phylogeny of Triturus indicates that NTV, body form, and aquatic ecology have evolved together, and suggest that they may underlie the adaptive radiation that characterizes Trituras.
