Variation in genetic traits of the lugworm Arenicola marina: temperature related expression of mitochondrial allozymes?
Genetic traits of the lugworm Arenicola marina were determined for four Atlantic populations from France to Norway and compared with a population from the sub-arctic White Sea in Russia. Seven loci were analysed using horizontal starch gel electrophoresis. A low heterozygosity (0.09-0.17) and a non-...

The genetic identity between lugworms of European Atlantic populations was high, whereas similarity of the Atlantic populations with the population from the White Sea was low. The gene flow between the Atlantic and the White Sea populations must be considered negligible, as deduced from the average high and significant gene differentiation FST.
