Whiteboard Populations Review

DTM and Pop. Pyramids DTM Graph: BR, DR, and overall population growth lines; label each stage; draw the shape of the population pyramid for stages 2, 3, and 4

Growth Rate (%) Calculate the growth rate of a population if: 75 births 20 deaths 5 immigrants 6 emigrants initial population = 25,000

How many years will it take the above population to double? Doubling Time How many years will it take the above population to double?

Population Density What is the population density of the above population (25,000) if they occupy an area of 15,000 km2? (Use the initial population).

% change In 1966 the world’s population had reached 3.4 billion. Today, the world’s population is 7.4 billion. What is the percent change in the world’s population from 1966 to 2016?

Natural rate of increase Mali has a CBR of 47 and a CDR of 10. What is Mali’s natural rate of increase? (expressed as a %)

Per capita What is the per capita oil consumption of the U.S. and Mali if: The U.S. uses a total of 420,000,000 gallons per day Mali uses a total of 250,000 gallons per day (pop. of Mali = 15.3 million)

Logistic Growth Make a graph that shows K, overshoot and dieback; label the portion of the graph that illustrates the biotic potential

Pop. Cycles Graph: A predator/prey cycle – solid line for prey and dashed line for predators (bottom-up population control)

Survivorship Graph: A population with a early survivorship vs. a population with a late survivorship, give an example for each; Label each as either r or K selected species.

Population Change Curve Graph: A population with an irruptive population change curve

Disease 1. Cholera 2. Blindness 3. Kwashiorkor 4. Anemia 5. Dysentery Label each as “I” as infectious or “N” for non-infectious: 1. Cholera 2. Blindness 3. Kwashiorkor 4. Anemia 5. Dysentery 6. Malaria 7. Marasmus 8. Minimata
