1
How does the fragmentation of a landscape have a positive effect on biodiversity?
It increases the amount of edge habitat.
2
Why is it important to consider the quality of the matrix habitat that exists between habitat fragments?
The quality of matrix habitat affects the ability of species to disperse.
3
Which is NOT a reason that species diversity decreases while moving toward the poles in the Northern Hemisphere?
Decreased environmental heterogeneity increases diversity.
4
Alpha diversity is
the number of species in a small area.
5
Why are corridors and habitat stepping stones important to the conservation of biodiversity?
They reduce the negative effects of habitat fragmentation
6
Which conditions would you expect to support the most species?
a large island close to the mainland
7
How has continental drift affected global patterns of biodiversity?
The separation of continents has increased diversity
8
Why are solar energy, precipitation on land, and ocean water temperatures important in determining global patterns in biodiversity?
They control the energy available to support species
9
How does knowledge of historic climate patterns affect our interpretation of present-day patterns of species diversity?
Tropical regions have been limited by the increased differentiation between the poles and equator.
