Diversification of shrub frogs (Rhacophoridae, Pseudophilautus) in Sri Lanka – Timing and geographic context
This paper is about the diversification of shrub frogs on the hills on the island of Sri Lanka - origins, patterns and rates. Hope this will help future research on this remarkable group
•Pseudophilautus diversification, begins during Oligocene (31 MYA)
•A stately pace of lineage accumulation despite orogeny and climate change.
•Assemblages in most regions comprise of species arising from diverse clades.
•MRCA of a back-migrating clade to India (8.8 MYA), reconstructs as a lowland form.
•Island’s mountains serve as species pumps and refuges for Pseudophilautus evolution.
