Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...
