We characterizedthe genetic structure of the Eurasian otter (Lutra lutra)meta-population living in the core of its Italian distribution range providingresults from 191 fresh spraints, collected from 24 watercourses included in SouthernItaly. Furthermore, according to ecological corridors and barriers, we discussthe likely ways of movement and possible evolutionary fate of thesepopulations. We genotyped 136 samples using 11 Lut microsatellite nuclearmarkers amplified from faecal DNA. Microsatellites were moderately variable (Ho= 0.45; He = 0.46), with a total number of alleles and averagenumber of alleles per locus in the meta-population of 50 and 4.54,respectively. No significant heterozygosity excess was observed inmeta-population suggesting no recent population bottlenecks. Bayesianclustering discriminated a sub-structuring of the meta-population in fiveputative clusters, indicating that local populations are geneticallydifferentiated: three of these seem to be identifiable with geographicallydefined sub-populations (from the Cilento, Agri and Basento river basins). Thefourth is represented by multiple sub-populations with admixed genotype, thatinclude genotypes from the Lao, Sinni and Abatemaco river basins, living in alandscape with the higher environmental permeability. Landscape genetic analysiscould provide evidence of an unexpected ecological corridor: the seacoast,highlighted, for the first time as a new way for the dispersion of the South-Italianotters. Deepening the knowledge of these perspectives is crucial to identifysolid strategies aimed at the future health of the populations of the Italianotters, by restoring dispersal corridors and managing the watercourses.
