Exam 17: Biogeographic Divisions

The climate of the tropical rain forest biome is best described as

All needleleaf trees are evergreen.

New Zealand and Australiaʹs remarkably similar fauna suggests that they were connected,either as a single land mass or by a land bridge,during critical evolutionary times.

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.

Alpine tundra vegetation is characterized by evergreen needleleaf trees.

The boreal and montane forest biome is characterized by broadleaf deciduous trees.

What is conservation biogeography? What are its primary focuses?

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

This biome consists of large expanses of xerophytic grassland,scattered trees and shrubs adapted to drought,grazing by large herbivores,and fire.

The naturalist and father of zoogeography Alfred Russel Wallace noted a distinct difference in the fauna between several islands in the Malay Archipelago (present -day Indonesia).He used these differences to delineate the boundary between the Australian and Oriental biogeographic realms.Which of the following best describes the reason for these differences?

Earthʹs biodiversity is evenly spread across the planet.

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

Anthropogenic biomes,while not replacing the concept of terrestrial biomes classification,provide insight into the role humans have played in shaping the worldʹs ecosystems.

Alfred Russel Wallaceʹs zoogeographic realms roughly correspond to continental plate boundaries.

Home to the endangered Northern Spotted Owl,this biome is now characterized by anthropogenic disturbance and mostly secondary-growth forest.

Which of the following soil types is most associated with the tallgrass prairie (midlatitude grassland)?

This extensive biome stretches from the east coast of Canada to the Canadian Rockies,as well as across the entire extent of Russia to the European Plain and at high elevations at lower latitudes.

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

The most powerful biotic agent on Earth,influencing all ecosystems on a planetary scale is

Most non-native species introduced to a new community become established there.
