Atlantic salmon Salmo salar in the chalk streams of England are genetically unique
Recent research has identified genetic groups of Atlantic salmon Salmo salar that show association with geological and environmental boundaries. This study focuses on one particular subgroup of the species inhabiting the chalk streams of southern England, U.K. These fish are genetically distinct fro...

Recent research has identified genetic groups of Atlantic salmon Salmo salar that show association with geological and environmental boundaries.

The genetic population structure of S. salar occupying five chalk streams was explored using 16 microsatellite loci.
