Clone diversity of Eiseniella tetraedra (Oligochaeta: Lumbricidae) along regulated and free‐flowing boreal rivers
We have sampled populations of the parthenogenetic and polyploid earthworm Eiseniella tetraedra along the Ume, Vindel and Sävar Rivers in northern Sweden. The Vindel River is one of the last free‐flowing large rivers in NW Europe, while the Ume River, which flows parallel to it, is harnessed with tw...
