“…A decreasing trend in SDQ starts in late populations of Mimomys savini and continues in Arvicola ones. Sima del Elefante (Cuenca-Bescós et al, 2010a), Untermassfeld (Maul et al, 1998), Fuente Nueva 3, Barranco León, Gran Dolina TD 4B, TD 5b, TD 5a, TD 6-3, TD 6-2 and TD 6-1 (cette étude), Voigstedt (Maul et al, 1998), Meisenheim I (Kolfschoten, 1990), localités du Bassin Pannonien, d'Europe Centrale et de Weimar Ehringsdorf (Heinrich, 1982, Trinchera Galeria (Atapuerca) (Cuenca-Bescós et al, 2010a), El Mirón (Cantabrie) and the oldest populations of Arvicola cantianus display similar values to those of Mimomys savini. Moreover, the most modern populations of Mimomys savini (Gran Dolina TD 6-2, TD 6-1 and Voigtstedt) show a trend towards a reduction in this index, which is continued in Arvicola populations up to recent times.…”
