“…If we consider the Early Bronze Age in the Mediterranean and more generally in southern Europe, the isotopic data at Arano fall within the general isotopic setting. The sites of Padru Jossu and Is Calitas (Sardinia, Italy; Lai et al, 2007), Singen (Germany; Koch and Kupke, 2012), Perachora and Makrigialos (Greece, Petroutsa et al, 2007;Triantaphyllou, 2001), Chantemerle, Machal and Le Tourteix (Auvergne, France; Goude et al, 2011;Herrscher et al, 2014) and Cova de la Pastora, Coveta del Frare, Castillejo del Bonete, Motilla de Azuer, and Balearic Islands (Spain;García Borja et al, 2013;McClure et al, 2011;Nájera Colino et al, 2010;Nájera et al, 2012;Salazar-García et al, 2013;Van Strydonck et al, 2005), all dated to the beginning of the Bronze Age, show similar carbon and nitrogen ranges, suggesting that C 3 plants were a very significant nutritional source, typical of a temperate ecosystem. However, the moderate enrichment in 13 C for some sites is due to the presence of a more arid local environment (e.g.…”
