Targeted re-sequencing confirms the importance of chemosensory genes in aphid host race differentiation

TL;DR: Signs that chemosensory genes may be good candidates for local adaptation and barriers to gene flow in the pea aphid open the way to further investigations aiming to understand their impact on gene flow and to determine their precise functions in response to host plant metabolites.
Journal ArticleDOI
Transitions in cuticular composition across a hybrid zone: historical accident or environmental adaptation?
TL;DR: The pattern of variation in cuticular hydrocarbon blend in four transects through the hybrid zone of Chorthippus parallelus is described, suggesting that environment influences the constitution of the cuticle, and hence natural selection may interact with mating signals in this species.
Journal ArticleDOI
Sexes and species as rival units of niche saturation during community assembly
TL;DR: The most comprehensive test of the niche-packing equivalence theory at ecological time-scales (assemblage level) to date supports the prediction that sexual dimorphism and species richness are alternative outcomes of adaptive radiation.
Journal ArticleDOI
Chromosomal Speciation Revisited: Modes of Diversification in Australian Morabine Grasshoppers (Vandiemenella, viatica Species Group).
TL;DR: These findings suggest that geographical isolation leading to the fixation of chromosomal variants in different geographic regions, followed by secondary contact, resulted in the present day parapatric distributions of chromosome races.
