Estimates of current rates of extinction

Large urban parks such as Forest Park in Portland can approximate the ecological communities that existed in the area before the city was there. These parks are now surrounded by urban environments. Describe how island biogeography theory would predict how the ecological communities in a large urban park would change over time, compared to the community that existed before the city was built.

Which of the following statements best describes the effect of climate on biome distribution?

In a rural hilly neighborhood, a landowner uses bulldozers to clear all but the largest trees and cleans up a nearby stream, lining the bottom of the stream with decorative rocks and stepping-stones. Planting lawn grasses around the base of the trees, the owner wants to create a park-like setting around his home. We expect that in this ecological simplification of the cleared yard, there will be
