      abstract     = {Global changes have distinct influence on fluvial processes
                      in torrents causing erosion on slopes and riverbanks even in
                      forested areas. Continuous as well as discontinuous erosion
                      of riverbanks covered by trees frequently results in
                      destabilisation and finally cause the trees affected to tip
                      over. These uprooted trees may lead to a blockage of the
                      river and, in the case of a collapse of the resulting dam,
                      resulting in severe flooding or even debris-flow surges.
                      Dating the time of root exposure along riverbanks allows the
                      reconstruction of erosion dynamics. In the previous studies,
                      roots of coniferous trees have shown anatomical changes
                      (cell size reduction in earlywood) after exposure. This
                      anatomical feature in the xylem of exposed roots has helped
                      to determine the time of exposure at an annual resolution.
                      In the current study, this methodology is now applied for
                      the first time to European ash (Fraxinus excelsior L.) to
                      determine its specific reactions to root exposure.First
                      results show different reactions in vessel and fibre
                      dimensions. Fibres show a distinct decrease in lumen area
                      due to exposure, whereas vessel lumen area displays more
                      variability ranging from $50\%$ size reduction to no
                      changes. It is discussed that vessel size characteristics
                      are also related to ecophysiological and climatic patterns.
