- Most density-dependent factors show negative feedback relative to population size. Which one of the following is more likely to show positive feedback relative to population size?
- Select the description of a population pyramid for a population that has the largest potential for exponential growth.
- What is the most reasonable conclusion that can be made from data graphed in the figure.
- What is the most reasonable conclusion that can be made from data graphed in the figure.
- A species whose population growth is not well described by the logistic growth equation is likely to have all of the following traits except
- Some population parameters vary directly (as one increases, the second increases) and some vary inversely (as one increases, the second decreases) with population density. Which one of the following would be expected to vary inversely with population density?
- At what point in a population will zero population growth occur?
- Parental care of the young is usually associated with species with a Type ___ survivorship curve.
- Which one of the following factors that affects population growth is not a direct part of the logistic growth equation?
- Which one of the following is not a correct distinction about source-sink metapopulations?
- Allen's rule states that mammals from colder climates have shorter ears and appendages than individuals of the same species from warmer areas. The related Bergman's rule states that mammal body size varies with latitude, with larger body size in populations located closer to the poles and smaller body size in populations located closer to the equator. Both Allen's and Bergman's rule has to do with the fact that
- Select the feature that is not an important characteristic of a population.
- You construct a life table for a plant species and find that in all cases about the same proportion of the cohort survive to the beginning of the next time interval. Such a plant would have
- Which one of the following is not a physical environmental factor that determines where an organism can live?
- Spacing within a population for a species that is strongly territorial would be expected to be
- Population pyramids are primarily used to show
- All of the following apply to the demography of human populations today except
- The human population growth rate has declined over the past 30 years. This means
- The Allee effect occurs when
- A __________ would probably have a Type III life history.
- Which of the following factors is not one that increases the likelihood of population extinction?
- Many times species are composed of networks of distinct populations called metapopulations. Metapopulations occur in areas where
- An example of clumped distribution of a population is
- Populations have three basic types of dispersal patterns—clumped, random, and uniform. One can observe random distributions because
- In the logistic growth model, as the number of individuals in the population (N) approaches the carrying capacity (K), the intrinsic rate of growth (r)
