APES Chapter 5 Content Review Flashcards | Quizlet rainforests are found along coasts in temperate regions. Since there is no need to conserve moisture as their habitat is always wet, these trees do not spend energy on developing a thick bark. No Trees No Humans. | Our Science | Learn Science at Scitable - Nature By recycling, you will reduce the need for 5 How have plants adapted to the rainforest? Height growth is diminished whenever buttressing is developed, suggesting that the carbon resources of the tree are reallocated as a response to environmental conditions. Tree bark in the tropical rainforest is typically thin. Rubber Tree. (Image courtesy of Ecology Letters). Below this layer there is very little sunlight and trees have adapted to growing branches and leaves where sunlight can be obtained.

This makes it slow to seal injury sites, where branches have snapped off and also limits the overall growth rate of the tree. Introduction: The tropical rainforest is earth's most complex biome in terms of both structure and species diversity. The researchers found that tree-bark thickness across the globe is greater in ecosystems with higher incidence of fire. Often times the trunk and the larger branches have thorns. "As periods of drought begin to be seen more frequently in tropical forests the lungs of our planet the risk that these ecosystems will burn increases," said Coulson, who is familiar with the study but had no role in it.
