What is biogeography? - Answer: Study of patterns of variation in
species composition and diversity among geographic locations
Which biome has the most biodiversity? - Answer: Forest biomes
(tropical rainforests)
,How is tree species diversity affected by latitude? - Answer: Tree
species diversity decreases with increasing latitude
What are endemic species? - Answer: Species found only in one
place on Earth
The same community type or biome, varies in species richness
and composition depending on its _______________ on Earth -
Answer: location
Species richness and composition are not the same in every
___________________ - Answer: continent
Spatial scales are interconnected in a _________________ way -
Answer: hierarchical
The patterns of species diversity and composition at one spatial
scale set the conditions for patterns at _____________ spatial
scales. - Answer: smaller
What are the 4 spatial scales? - Answer: Global, regional,
landscape, and local scales
,Differentiate the 4 spatial scales - Answer: - Global scale: The
entire world
- Regional scale: Within areas of uniform climate
- Landscape scale: Physical geography and environmental features
of a region
Local scale: A community
What is a regional species pool? - Answer: All the species
contained within a region (gamma diversity)
How are differences in species diversity determined at the global
scale? - Answer: Rates of speciation, extinction, and dispersal
How are differences in species diversity determined at the
regional scale? - Answer: Extinction and dispersal limitation
How are differences in species diversity determined at the
landscape scale? - Answer: Migration and extinction rates
(shaped by landscape features)
How are differences in species diversity determined at the local
scale? - Answer: Species physiology and species interactions
, Differentiate alpha, beta, and gamma diversity - Answer: - Alpha:
Within community diversity
- Beta: Between community diversity
- Gamma: Total diversity (regional species pool)
Beta diversity connects species diversity between which two
spatial scales? - Answer: Local and regional scales
What is beta diversity? - Answer: Change in species number and
composition (turnover) from one community type to another,
across a landscape
_____________ diversity sets the theoretical upper limit on
species diversity for communities - Answer: Gamma
The regional species pool (i.e. gamma diversity) provides raw
material for ___________ assemblages - Answer: local
When local and regional species richness values are equal (slope =
1), what does that signify? - Answer: All species within a region
will be found in the communities of that region
