Exam 19: Landscape Dynamics

The landscape can be thought of as a shifting mosaic of habitat patches,each in a phase of successional development.

What does this figure suggest?

Patch size is generally more important for plant populations than for animal populations.

The ________ effect refers to the rich diversity of life that occurs along the border between adjacent habitat patches,represented by species from both adjacent patches and species adapted to edge habitats.

The theory of island biogeography predicts that large islands have more species than smaller islands.

Habitat fragmentation is harmful because no species are adapted to living along habitat edges.

Plants adapted to edge environments tend to be

The theory of island biogeography was developed for islands and cannot be applied to habitat patches within a larger landscape.

Subpopulations within a metapopulation are isolated from one another with no movement of individuals between subpopulations.

A(n)________ species lives within the borders of a habitat patch,avoiding edges where habitat change is abrupt.

The patchwork of different types of land cover is called a(n)________.

Island biogeography theory predicts that a 10-fold increase in area results in

When a forest gradually merges into a grassland over a wide area,the border between the two landscape patches is referred to as a(n)

Which of the following statements is true?

For a population to persist,which needs to be true?

Animal species inhabiting edges of habitat patches usually require two or more habitat types within their home range or territory.

Which of the following is NOT a general relationship?

What do these data suggest?

What would likely be true when P = 0.9?

Borders between patches that result from natural disturbances typically change over time.
