Document Summary
Know and understand the mechanisms employed by vegetation that enable them to cope with the types of climates for each; be able to locate on a map the natural vegetation types discussed in lectures. South america(especially brazil), and areas of central africa. Areas of brazil, australia, india, and southeast asia. The straight tree trunks and umbrella-shaped canopies of the trees creates an intense competition for sunlight. Buttress roots absorb nutrients from the thin organic layer found on the topsoil and anchor the tree. Epiphytes- plants that climb upon the tree trunks for support and sunlight. Air plants- the roots of these plants are on the canopy level itself and never reach the ground level. Long and extensive root systems to reach ground water in deep reservoirs. A few plants store water in their trunks during the wet season. Acacia plants have spine leaves to repel animals and reduce transpiration. The harsh climate lacks water to support full grown trees.
