Researchers Find a Phylogeographic Evaluation of Amolops Mantzorum Species Group
May 12, 2014 Email"> PrintText Size
The recent rapid uplift of the Plateau caused dramatic habitat and climatic changes, which in turn may have promoted speciation events. The cascade frogs of the Amolops mantzorum group are the dominant vertebrate species in the forest-stream ecosystem of the eastern escarpment of the Tibetan Plateau. This provides an excellent system to study interactions between geography, geology and speciation.
Prof. FU Jinzhong and Dr. LV Bin of Chengdu Institute of Biology used DNA sequence data from a mitochondrial marker and a nuclear marker to examine phylogeography of the Amolops mantzorum species group. Using newly developed species-delimitation methods, they clearly delimited nine species, including four well-recognized species and five putative species, of which three are often listed as synonyms of A. mantzorum. The nominal species A. mantzorum may in fact included two cryptic species.
Divergence-time estimates aligned the speciation events with the recent intense uplift of the Tibetan Plateau in the last 3.6 million years. The species-distribution modeling also revealed different habitat preferences among species that were potentially linked to climatic changes associated with the uplift.
These geological events and climatic changes may play an important role in the speciation process and the formation of the current diversity pattern. This project is supported by the National Natural Science Foundation of China and China Postdoctoral Science Foundation. The results were published on Molecular Phylogenetics and Evolution,
