An experimental procedure using biotin-labelled probes and streptavidin-bound magnetic beads (FIASCO) was used to produce a microsatellite-enriched library for the collembolan Orchesella villosa.

Abstract

An experimental procedure using biotin-labelled probes and streptavidin-bound magnetic beads (FIASCO) was used to produce a microsatellite-enriched library for the collembolan Orchesella villosa. PCR primers were successfully constructed for seven loci containing, respectively, five pure, one interrupted, and one compound dinucleotide microsatellite repeats. As a preliminary test of their variability, we investigated 15 individuals from 5 locations inside a dismissed mining area in southern Tuscany. All microsatellite loci showed high levels of polymorphism. The mean number of different alleles at each locus across populations was 10.1 and observed heterozygosity per locus was 0.13–0.86. Only 2 out of the 7 loci appeared to be in Hardy–Weinberg equilibrium. The potential application of these loci to test the effects of environmental contamination on the genetic structure of exposed populations is discussed.
