FIGURE 3 in Diversity and taxonomy of the genus Unio Philipsson in Italy, with the designation of a neotype for Unio elongatulus C. Pfeiffer (Mollusca, Bivalvia, Unionidae)

FIGURE 3. Unio mancus median-joining haplotype network based on a fragment of the mitochondrial gene encoding for the cytochrome oxidase subunit I (mtDNA COI). Dashes indicate substitution steps. Each circle represents a haplotype and its size is proportional to its frequency. AtlFrN: Atlantic N-French basin (Seine); AtlFrW: Atlantic W-French basins (Blez Jean, Laïta, Loire, Charente, Garonne, Adour); MedFrE: Mediterranean E-French basin (Argens); MedFrC: Mediterranean centre-French basins (Rhône, Hérault); MedFW: Mediterranean W-French basin (Tet); MedSp: Mediterranean Spanish basins (Ebro, Fluviá, Júcar, Llobregat, Sionlla, Ter); Corsica: Corsican basins (Golo, Orbu, Stabicciu, Taravo, Tavignano); Sardinia: Sardinian basins (Cedrino, Liscia, Tirso); Sicily: Sicilian basin (Belice); TyrrApp: Apennine-Tyrrhenian Italian basins (Magra, Arno, Ombrone, Volturno); IonApp: Apennine-Ionic Italian basin (Bradano). See Appendix B for detailed information on the analysed haplotypes.
