The status and cycling of boron (B) were examined in two forest types in Greece, a maquis and a mountainous fir forest. In the hydrological cycle, in both forest types, the B concentration in the bulk deposition was significantly lower than that in throughfall implying dry deposition. It was also shown that some long-range transfer of B took place...

Conference Paper
Full-text available
Forest ecosystems are unique in having a detailed description of historical events and disturbances imprinted in the tree-ring record. Fire is the most important disturbance and it is found that fire scarred trees have this event depicted in their tree-rings. The climate is another factor that leaves an imprint in the tree-ring record. Defoliation...
