Haplotype variation in the spiny-cheek crayfish Orconectes limosus: colonization of Europe and genetic diversity of native stocks

Abstrakt

To test wheather different European spiny-cheek crayfish populations were likely to have come from a single source and to identify their possible origin, we analyzed the diversity of mitochondrial gene for cytochrome c oxidase subunit I (COI) of O. limosus individuals from Europe and from its original range in North America, including the presumed source region of European populations, the Delaware River watershed (eastern USA).
