Variation in genetic traits of the Baltic clam Macoma balthica from a tidal gradient in the subarctic
In a subarctic tidal gradient, strong heterogeneity in genetic traits of the Baltic clam Macoma balthica was found. The heterogeneity was stronger within the intertidal gradient, over a distance of only about GO mi than along a horizontal gradient over a distance of 1200 km in clams from the west Eu...
