Leaf structure does not reflect the extreme environmental conditions to which trees in Amazonian floodplains are subjected. No patterns could be detected of a relationship of leaf functional traits with flooding intensity and

This can be crucial in an environment with a flood amplitude exceeding 10m. Time for seedling establishment in the non flooded terrestrial period is reduced to few months or weeks.

Seed Germination and Seedling Establishment of Amazonian Floodplain Trees highly flooded low-várzea tree species are well-adapted to tolerate the seasonal inundations, while seedlings from low and irregularly flooded high-várzea tree species are poorly-flood adapted thus reacting very sensitive to flood pulse variations.
