Southeast Asia is one of the world’s richest regions in terms of
biodiversity. An understanding of the distribution of diversity and the
factors shaping it is lacking, yet essential for identifying conservation
priorities for the region’s highly threatened biodiversity. Here we take a
large scale comparative approach, combining data from nine forest
associated Anopheles mosquito species and using statistical
phylogeographic methods to disentangle the effects of environmental
history, species specific ecology, and random coalescent effects.
Spatially explicit modelling of Pleistocene demographic history supports a
common influence of environmental events in shaping the genetic diversity
of all species examined, despite differences in species' mtDNA gene
trees. Populations were periodically restricted to allopatric northeastern
and northwestern refugia, most likely due to Pleistocene forest
fragmentation. Subsequent southwards post-glacial recolonisation is
supported by a north-south gradient of decreasing genetic diversity.
Repeated allopatric fragmentation and recolonisation has led to the
formation of deeply divergent geographical lineages within four species
and a suture zone where these intraspecific lineages meet along the
Thai-Myanmar border. A common environmental influence for this divergence
was further indicated by strong support for simultaneous divergence within
the same four species, dating to approximately 900 kya. Differences in the
geographical structuring of genetic diversity between species are likely
the result of varying species’ biology. The findings have important
implications for conservation planning; if the refugial regions and suture
zone identified here are shared by other forest taxa, the unique and high
levels of genetic diversity they house will make these areas conservation
priorities.
