Abstract:
The structure and chemistry of canopies reflect differences in biogeochemical cycling,
plant physiology and biological diversity that affect all life occupying a forest
environment. Changes in species composition can alter forest structure and chemistry,
and introduced species are sometimes uniquely capable of changing resource
distributions in forest ecosystems. Invasive species can also alter the biological diversity
of ecosystems they invade. This is particularly true in the once isolated tropical forest
environments in Hawai'i and similar places around the world.
