The book discusses the method of using a crane to study forest canopies. One well-known crane is in the forest in Washington near the Columbia Gorge, the Wind River Canopy Crane. Another well-studied forest ecosystem, but not with a crane, is the Hubbard Brook Experimental Forest in New Hampshire. Especially noteworthy because many long-term studies of all sorts have been conducted at Hubbard Brook, including nutrient cycling and community energetic. Many methods of studying vegetation change over time.
Pollen analysis is especially valuable, where it's feasible.
Patterns Biome - the largest commonly recognized division of terrestrial communities. Biomes are distinguished primarily by their predominant plants and their locations are determined primarily by climate. Soil Soil is influenced by climate and the biota living in that climate. Climate Temperature, Atmospheric circulation, an precipitation Many of the differences in climate is created by uneven heating of the earth's surface. The greater the latitude, the more seasonal the climate.
