The evolution of South American populations of Trimerotropis pallidipennis (Oedipodinae: Acrididae) revisited: Dispersion routes and origin of chromosomal inversion clines

In the past few years large-scale genome sequencing has demonstrated that inversion rearrangements are more frequent than initially hypothesized. Many examples suggest they may have played an important function in delineating the evolution of biodiversity. In particular, clinal patterns of variation...

description In the past few years large-scale genome sequencing has demonstrated that inversion rearrangements are more frequent than initially hypothesized. Many examples suggest they may have played an important function in delineating the evolution of biodiversity.

Within grasshoppers, Trimerotropis and Circotettix show high incidence of inversion rearrangements, either in fixed or polymorphic state, according to which several hypotheses about phylogenetic relationships have been proposed. Herewith we review the evolutionary significance of inversions in Trimerotropis pallidipennis, whose South American populations show clinal variation for pericentric inversions along environmental gradients.
