GEOGRAPHY IN THE NEWS:
By mapping tree chemistry, scientists have discovered there to be 36 kinds of forest in what, from the air, would seem to be a single swath of Peruvian forest. Defining a forest by its underlying topography and microclimate and the kinds of plants and animals it supports, researchers have provided local people and conservationists with a more nuanced understanding of what cutting down -- or preserving -- one stand of trees vs. another might mean for the biological function of the area.
