Phylogeography of the coastal mosquito Aedes togoi across climatic zones: Testing an anthropogenic dispersal hypothesis
The coastal mosquito Aedes togoi occurs more or less continuously from subarctic to subtropic zones along the coasts of the Japanese islands and the East Asian mainland. It occurs also in tropical Southeast Asia and the North American Pacific coast, and the populations there are thought to have been...
