Tree species shape the elemental composition in the lichen Hypogymnia physodes transplanted to pairs of spruce and beech trunks
چکیده انگلیسی

The lichen Hypogymnia physodes was sampled from spruce trunks and we used to assess natural elements in the throughfall from pairs of neighbouring beech (Fagus sylvatica) and spruce (Picea abies) canopies in an unmanaged forest reserve. The beech bark (pH = 4.36 ± 0.13) was less acidic than spruce bark (3.71 ± 0.06). After a 1 yr transplantation onto trunks, lichens on beech had significantly higher concentrations of Ca, K, Mg and P than on spruce, and lower Mn, Zn and C, but had similar Al, B, Fe, N, Na, S and Si concentrations. Base cations (Ca, Mg, K) in lichens highly significantly increased with bark pH, with no overlap between tree species neither for base cations, nor for pH. The results are consistent with the view that trees modify the elemental composition of lichens in their dripzone, and that trees at least to some extent can modify the elemental chemistry of their local surroundings and thus influence ecosystem processes. We discuss lichen transplantation as a method to estimate long-term effects of tree species on local chemical environments.
