The SimUText chapter provides 4 short-time-scale (ecological) explanations for why the latitudinal biodiversity gradient pattern exists. Pick two of the explanations and provide the ecological reasoning behind them.• Regional Energy Availability• Water Availability• Net Primary Productivity• Habitat Diversity

Which of the following is predicted to be a major driver in biodiversity loss:

In the accompanying figure, which number would designate the arctic tundra biome?

Loss of biodiversity around the world threatens the existence of the human population as well since humans depend on other species for:

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.

Estimates of current rates of extinction

We should care about loss in biodiversity in the populations of other species because of

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
