Exam 20: Terrestrial Biomes

Which of the following is a topic of research in conservation biogeography?

The Serengeti in east Africa is an example of which biome?

Tropical savannas are treeless areas in the equatorial region.

Due to the dense tropical rain forest canopy, only about 1% of the sunlight arriving at the canopy reaches the forest floor.

The biome concept has been applied equally to marine and aquatic systems as it has to terrestrial systems.

The flora and fauna of this biome is characterized by high biodiversity, including many lianas, epiphytes, and arboreal animal species, such as sloths, monkeys, lemurs, and snakes.

The Earth's tallest trees are the

This biome is characterized by a well-developed vertical structure with three distinct layers: an overstory, a middle canopy, and understory.

The Mediterranean shrubland biome is the most extensive terrestrial biome.

Due to international pressure, tropical deforestation has largely ceased except in a few isolated pockets of Amazonia and equatorial Africa.

Humans are the most powerful biotic agent on Earth, influencing all ecosystems on a planetary scale.

Biogeographic regions (realms) are delineated based on species assemblages and their evolutionary history.

Most desert plants are xerophytic with numerous mechanisms to cope with dry conditions.

In which of the following regions would one likely not find a tropical rain forest?

This biome is typically found in areas with marine west coast climates, characterized by high precipitation, moderate air temperatures, summer fog, and an overall maritime influence.

Tropical savanna soils are much higher in humus than the soils of the tropical rain forest.

The most extensive anthropogenic biome is croplands.

Several distinct communities of midlatitude broadleaf and mixed forests are found in North America, Europe, and Asia.

Most forests in the temperate rain forest are old growth.

Which of the following is not one of the major groups of terrestrial vegetation biogeographers often designate?
