Here is my question:
I have used several kinds of genetic markers to reconstruct the phylogeographic history of a kind of bats. A geographic relatively isolated population (call it YM population) contained three adjacent phylogeographic clades inference from mtDNA with lowest nucleotide diversity and haplotype diversity in both mtDNA and ncDNA, and firstly isolated from other populations in microsatellite analysis. ncDNA suggested weak geographical pattern of all clades inferred from mtDNA.
I want to figure out the potential origin of YM population, or the possible reasons for low nucleotide diversity and haplotype diversity in both mtDNA and ncDNA. By the way no bottleneck (based on microsatellite) or expansion (based on mtDNA) was detected.
Any suggestion will be appreciated including the question itself.
Maybe it is result of introgression of two mtDNA clades in ancient YM population.
Or it could have resulted from a "recent" founder event. You can try IMA2 or DiYABC to check the demographic history of the population, in relation to the other ones around.
Thans everyone for your help, I really appreciate your energy and time。 I will try IMA2 or DiYABC to check the DH of the population. Again, thank you. Also, I will think about the efect of introgression.
Depends on the number of loci and quality of the data. IMA2 and DiYABC requires many loci and high quality of the data. Use different bottleneck tests. To check for contemporary bottlneck you can try Wang's Colony.
