Geographic Ecology and Biogeography

Flashcards on Geographic Ecology, Island Biogeography, and landscape Ecology.

__ describes the geographic distribution of species richness over evolutionary time.

Biogeography

__ biogeography involves species ranges being split into isolated regions through processes like changes in continents or glaciation.

Vicariance

__ attempts to combine community ecology with biogeography, incorporating abiotic predictors and climate change.

Macroecology

Most plants and animals show gradients of species richness and diversity from high richness in to low richness in regions.

tropics, polar

In arid climates, species richness may be highest at __.

mid-elevation

Actual evapotranspiration refers to __ and energy.

water availability

__ noted that small oceanic islands have fewer species than larger islands or mainlands.

Darwin and Humboldt

__ (1921) first used the power law equation to describe species-area relationships.

Arrhenius

MacArthur and Wilson developed the Theory of __ in 1967.

Island Biogeography

In Diamond's study on the Channel Islands CA, smaller and more distant islands had __ bird species than larger islands closer to the mainland.

fewer

Wilson and Simberloff conducted __ experiments on mangrove islands to study island biogeography.

defaunation

Reducing the area of islands leads to a __ in the number of arthropod species.

decrease

The Biological Dynamics of Forest Fragments Project is located in __.

Manaus, Brazil

Over 30 species of ant-following birds are associated with __ in rainforest fragments.

army ants

__ ecology considers the spatial configuration and heterogeneity of lands as determinants of ecological patterns.
