| tests of conspecificity for allopatric vectors: simulium nodosum and simulium shirakii (diptera: simuliidae) in asia. | allopatric populations present challenges for biologists working with vectors. we suggest that conspecificity can be concluded in these cases when data from four character sets-chromosomal, ecological, molecular, and morphological-express variation no greater between the allopatric populations than between corresponding sympatric populations. we use this approach to test the conspecificity of simulium nodosum puri on the mainland of southeast asia and simulium shirakii kono & takahasi in taiwan. ... | 2015 | 26022092 |
