Patterns of tree cover may well very by the arraingment of the
terresphere--so what is true in OZ may differ for what is true in,
say, N. America.
But the bottom line is this. Pine or evergreens at or near a snow
line are going to have a different impact on what gets washed down
into rivers. Trees with falling leaves are going to cause rotting
material to flow down into rivers in a seasonal pulse--in the fall
and winter or even the spring with the initial rains--to be set for
prime microbrial conditions in the spring when the heaviest winds
induct currents, and make for regional storm conditions. So it
would make sense that certain trees would evolve for certain climate
conditions, particularly for mountain regions or snow line regions
compared to forrested plains.
Tropical plants seem to be another thing altogether, limited by
nutrients found in the soil but not by season. Seasonal pulses of
increased electrical insulation from hydrates wouldn't help their
survival--IMO. Therefore, they do not defoliate with teh seasons.
Evolution is awesome.
