“…Melanium; 2n = 26), a species occurring both on metalliferous (Zn, Pb, Cd, Cu) and on non-metalliferous soils in Western and Central Europe (Dobrzańska, 1955;Ernst et al, 2004;Banásová et al, 2006;Hildebrandt et al, 2006Hildebrandt et al, , 2007. Our previous research addressed the influence of soils polluted with heavy metals on the plant antioxidative system (Słomka et al, 2008), plant morphology, reproduction and pollen viability (Słomka et al, 2010c), mycorrhiza colonization (Słomka et al, 2011a) and genetic variation (Słomka et al, 2011b).…”
