1In exponential population growth, r increases as population size increases.
- ATrue
- BFalse
2Population growth rates are usually close to r(max).
- ATrue
- BFalse
3If r=0.2 for a population, population size is:
- Adecreasing
- Bneither; r does not indicate population growth
- Cincreasing
- Dstable
4Carrying capacity, or K, is:
- Avariable in time and space
- Ban indicator of fecundity
- Cfixed for each population
- Da feature of exponential population growth
5Logistic population growth is density-dependent.
- ATrue
- BFalse
6Population growth rate can be defined as:
- Achange in number of individuals per unit time
- Bthe maximum number of individuals a habitat can support
- Cbirth rate x death rate
- Dmass gained by individuals per unit time
7A hurricane wipes out most of a population of palm trees. This type to limiter of population growth is:
- Adensity-dependent
- Bdensity-independent
- Cnegative exponential
- Dlogistic
8What kind of population growth curve is this?
- Alinear
- Blogistic
- Cexponential
- Dparabolic
9Exponential population growth is density-independent.
- ATrue
- BFalse
10In what type of species would r(max) be highest?
- Ayoung age-at-maturity, few offspring
- Byoung age-at-maturity, many offspring
- Cold age-at-maturity, many offspring
- Dold age-at-maturity, few offspring
11What limits growth of hare populations?
- Apredation by lynx
- Bfood availability
- Cspace
- Dboth a and b

12Which of the following statements about metapopulations is FALSE?
- Aa metapopulation is a population of populations
- Bpopulations that have gone extinct can be restored
- Coverall population size (summing all patches) is constant
- Dthere are 'core' populations that never go extinct
13In a metapopulation, there is a balance between extinction and (re)colonization.
- ATrue
- BFalse
14Many of the hypotheses that have been developed to explain population cycles (including in hares) involve:
- Adensity-dependent factors
- Bdensity-independent factors
- Ccarrying capacity
- Dage-specific factors
15Projections for human population growth depend primarily on what factor?
- Ainfant mortality rates
- Boverall survivorship
- Cfertility rates in women
- Ddisease eradication
16Which of the following is TRUE about the current status of the human population?
- Athe population is increasing, but r is decreasing
- Bthe population is increasing; r=0.5
- Cthe population is increasing, and r is increasing
- Dthe population is stable; r (population growth rate) = 0
17You are a human demographer, and you see an age pyramid that looks like the figure below. What would you say about this population?
- Athe population is growing rapidly
- Bnone of the above
- Cthe population is dominated by people past reproductive age
- Dthe population has reached carrying capacity
