Abstract excerpt
The genetic structure of earthworm (Lumbricus rubellus) populations from plots (N = 3) contaminated by sewage sludge (containing Cd, Cu, Pb, Zn) and reference plots (N = 3) was compared. Earthworms (N = 30-40 per plot) were collected during May 2000 and electrophoretic analyses were used to assess genetic variation at three polymorphic loci (GPI, LAP, PGM). Allele and genotype frequencies for GPI and PGM differed...
