Climate Change and Truffles

Climate change is affecting the distribution of many species, including those from the fungal genus Tuber (truffles). As a result, some truffle species are conquering new habitats and spreading throughout the Europe. One such example is the black truffle (Tuber melanosporum), which, together with the summer truffle (T. aestivum), is increasingly found in Croatia. In this study, the differences in chemical composition of summer and black truffles, associated soil and bark of symbiotic plants are discussed. For this purpose, a total of 44 summer truffle and 7 black truffle samples were collected, as well as the same number of associated soils and barks. In all these samples, the total concentrations of 36 elements were determined by mass spectrometry after the samples were digested appropriately. The concentrations in the different truffle species and their associated soils and barks were compared using statistical methods. The results show that, despite statistically significant differences in the composition of soil (for the elements Bi, Cd, Cr, K, La, Mo, Na, P, Pb, S, Sn, Tl, V and Y) and bark (for the elements As, Al , Ba, Be, Bi, Ce, Cd, Co, Cr, Cs, Fe, La, Li, Na, Ni, P, Rb, S, Sb, Sc, Sn, Tl, U and Y), there is little difference between two truffle species. In fact, statistically significant differences between summer truffle (T. aestivum) and black truffle (T. melanosporum) were found only for Cd, Mg and S.
