Effects of pollution on heterozygosity in the barnacle Balanus amphitrite (Cirripedia: Thoracica)

Abstract

The effects of thermal and chemical pollution on gene and genotype frequencies and on multilocus structure were studied in 3 populations of Balanus amphitrite from the lagoon of Venice, Italy. Thermal pollution does not seem to play any important selective role. The hypothesis is advanced that selection is operated by heavy metals. -from Authors
