A population of quail lives in an area of prairie grasslands. In good years, a pair of quail can have four clutches of young, with as many as 12 to 14 eggs in each clutch. Despite this, the population size remains stable over the long term. Discuss the
population structure, its potential for growth, and its possible limiting factors, using at least four of the terms you learned in this chapter.
What will be an ideal response?
Students might discuss the r-selection strategy of quail and their potential for exceeding the population's typical carrying capacity in a "good" year with mild weather and plentiful food. They might talk about the population distribution (clumped). They might choose to discuss the survivorship curve (type III), involving the large number of eggs and chicks and the rapid loss of young. Density-independent factors would include things such as weather and drought or floods. Some density-dependent factors might be disease, predators, available nesting sites, and the amount of food available.

Fly to Point 3. Click the “+” button on the Zoom control to move in closer to this sharp turn called “Bowknot Bend” along the Green River. Using the forward arrow on the Move control, fly over the landscape until you have a clear view of Point 3 along the river bottom. From this angle, it may appear that clouds are draped over the ridge between the tight loops in the river’s course. The historical imagery you see was taken in 2003 from a vantage point nearly directly overhead of this area and the clouds were not really this low to the ground, so why do the clouds appear this way in Google Earth™?

Looking at Figures 24-1 and 24-2, does the recent increase in global temperature exhibit such a lag?
The question is based on Figure 24-5, showing variations in CO2 and temperature anomalies in Antarctica going back 800,000 years. This temperature record shows the major glacial (cold) and interglacial (warm) periods of the later Pleistocene Epoch (2.58 million to 11,700 years ago). Research suggests that over the last few hundreds of thousands of years, changes in atmospheric CO2 concentration sometimes lagged behind a temperature increase by perhaps 1000 years—indicating that “feedback” loops associated with a warmer climate might lead to increasing CO2 in the atmosphere rather than the other way around.
